Executive Summary and Recommendations
The 1983 La Paz Agreement defines the border area as 100 kilometers
on each side of the U.S. /Mexico international boundary. In
response to the Agreement and subsequent annexes, binational Work
Groups were established and formal communication procedures were
developed to address environmental concerns relating to water,
hazardous waste, air, contingency planning/emergency response,
enforcement, and pollution prevention issues affecting the border
area.
On November 27, 1990, the Presidents of the United Mexican States
and the United States met in Monterrey, Nuevo Leon, Mexico, to
discuss issues important to both countries including environmental
conditions along the U.S./Mexico border. The Presidents agreed to
direct their respective environmental authorities to jointly
develop a comprehensive border environmental plan designed to solve
environmental problems in the border area.
In February 1992 the Integrated Environmental Plan (IBEP) for the
U.S.-Mexican Border Area was released to the public. The scope of
the plan is such that the activities specified represent a series
of actions designed to ultimately achieve environmental results
along the border.
In response to the ground water protection concerns referenced in
the IBEP, the Environmental Protection Agency, Region 6,
established a Ground Water Protection Sub-group to address its
unique ground water concerns. The sub-group is chaired by EPA
Region 6 Office of Ground Water and is composed of representatives
from the Texas Natural Resource Conservation Commission, New Mexico
Environment Department, Texas Water Development Board, Texas
General Land Office, Texas Bureau of Economic Geology, U.S. Section
of the International Boundary and Water Commission, and the U.S.
Geological Survey.
The scope of the Sub-group was geographically limited by the Water
Work Group to the vulnerable Hueco and Mesilla Bolson aquifers in
the El Paso/Ciudad Juarez area. The work accomplished by the
Ground Water Protection Sub-group during FY93 and for the remainder
of FY94 will establish the foundation for future tasks during Phase
II (FY95 - FY00), which should include the entire Border Region.
The following major accomplishments and recommendations are
presented so they may be considered for implementation during the
1995 - 2000 time frame. The recommendations for specific
activities relate to the four objectives defined for the Ground
Water Protection Sub-group.

MAJOR ACCOMPLISHMENTfl:
•	The Ground Water Protection Sub-group coordinated
the development of a Ground Water Quality Data
Format that will be used as a basis for the
exchange of ground water quality data between the
governments of the United States and Mexico.
•	The Sub-group participated with EPA Headquarters in
the development of a catalog of Geographic
Information System (GIS) applications for the water
environment in the Border Region.
•	In June 1993 Sub-group representatives hosted a
tour of the El Paso Wellhead Protection project
area. Mexican government officials from Comision
Nacional del Agua (CNA), Mexican Section of IBWC
(CILA), and Ciudad Juarez were briefed on the
El Paso project and other ground water protection
programs that are being implemented in the United
States.
•	The Sub-group has provided National Wellhead
Protection program guidance, technical assistance
documents, and the El Paso Ground Water Protection
Strategy to the Chair of the Water Work Group to
send the Mexican Government.
•	EPA, coordinating through the Sub-group, has
awarded $159,000 in assistance funds for Wellhead
Protection Demonstration Grant projects in the
El Paso/Ciudad Juarez/Las Cruces area. These funds
are for the implementation of a Wellhead Protection
Program for El Paso County, Texas, the City of
Las Cruces in Dona Ana County, New Mexico, and for
Ciudad Juarez, Chihuahua, Mexico.
SUB-GROPP RECOMMENDATIONS:
The following specific recommendations are targeted to the Water
Work Group and to the U.S. Federal and State agencies as indicated:
RECOMMENDATIONS FOR THE WATER WORK GROUP:
•	The Sub-group recommends that international linkage
and electronic access to data and data
documentation are needed in the agreed upon format
and that GIS technology be used to facilitate data
management.

-------
-3-
•	The Sub-group recommends that studies be conducted
that will identify the region's transboundary
aquifers, quantify the natural and induced chemical
quality of each aquifer, characterize and quantify
the available supply of each aquifer, determine the
direction of ground water flow and its relationship
to the flow of the Rio Grande/Rio Bravo, and
develop GIS coverages of the region. The
information obtained from this ' study will
contribute to an environmental baseline that could
be used to facilitate technical and policy
decisions.
RECOMMENDATIONS FOR U.S. FEDERAL AND 8TATE AGENCIES:
•	The Ground Water Protection Sub-group has been
involved in the successful implemention and
coordination of ground water protection activities
in the El Paso/Ciudad Juarez/Las Cruces area, and
based on this experience recommends that such
efforts be expanded to the other areas of the
U.S./Mexico Border.
Priority should be given through a risk-based
approach to those areas where human health or
ecosystems are presently imperiled or threatened.
•	The Sub-group recommends that the catalog of Water-
Related Geographic Information Systems Along the
United States-Mexico Border (EPA-832-B-93-004) be
expanded to include a database inventory of the
systems.
•	The Ground Water Protection Sub-group recommends
that the Sub-group, or its equivalent, be continued
to provide technical assistance to the Work Groups
established by the La Paz Agreement. In addition,
a binational membership would be beneficial. A
binational coordinated effort at the Sub-group
level can serve an important role for coordination
of border area activities. Such a coordinated
effort would increase efficiencies and avoid
redundancy.

-------

ACTIVITIEB FOR THE BALANCE OF FY94:
Highlights of activities planned by the Sub-group for the second
half of FY94 are as follows:
•	Based on information obtained from the appropriate
authorities in the U.S. and Mexico, the Sub-group will
continue to work with the Mexican government through
IBWC in developing an inventory of the shared ground
water sources and ground water quality for the sister
cities of El Paso, Texas, and Ciudad Juarez, Chihuahua.
This information will be digitized and entered into the
Region 6 GIS database and made available to other
federal, state, and local governments.
•	Based on ground water quality monitoring data gathered
from the appropriate authorities in the U.S. and
Mexico, the Sub-group will continue to identify areas
where any transboundary ground water source or any
potential transboundary ground water source of drinking
water is contaminated or where there is an identifiable
threat of contamination to these sources of water.
•	The Sub-group will participate as appropriate in the
development of the U.S./Mexico Border Action Plan
(Second Stage Plan, 1995 - 2000) during FY94.

INTRODUCTION
The upper region of the Rio Grande/Rio Bravo in Texas and New
Mexico occupies a part of the physiographic province known as the
Chihuahuan Desert and, except for the Rio Grande/Rio Bravo,
contains virtually no permanent surface water source. In this
region where the surface evaporation rate is 10 tines the average
annual rainfall, and surface water is in short supply, reliance on
ground water resources is vitally important.- Host of the
communities lying within this region obtain all of their water
supply from underground sources. Likewise, most other water users,
with the exception of the river valley irrigators, rely exclusively
on underground sources of water for and other domestic uses.
Several conditions in the region have changed during recent years
that warrant a closer review of existing water resources. Some of
these conditions are:
1.	Rapid population expansion in the City of El Paso
and Ciudad Juarez has created a growing demand for
fresh water and potentially threatens ground water
quality.
2.	Numerous colonias (communities without public water
supplies or wastewater treatment systems) and other
economically disadvantaged areas have become
established along the Rio Grande/Rio Bravo
corridor. An adequate water supply of suitable
quality is needed for these areas.
3.	In an effort to protect the existing ground water
resources, the City of £1 Paso has implemented a
Wellhead Protection (WHP) program that is designed
to provide an additional level of protection to
delineated areas around its 138 public water supply
wells. The El Paso City/County Health and
Environmental District is extending the City's WHP
program to cover all of El Paso county.
BACKGROUND
The 1983 Agreement between the United States of America and! the
United Mexican States on Cooperation for the Protection and
Improvement of the Environment in the border area (often referred
to as the La Paz Agreement), defines the border area as an area 100
kilometers on each side of the international boundary.
In response to the La Paz Agreement and subsequent annexes,
binational Work Groups were established and formal communication
procedures were developed for addressing principal environmental
concerns relating to water, hazardous waste, air, contingency
planning/emergency response, enforcement, and pollution prevention
issues affecting the border area.

-------
On November 27, 1990, the Presidents of the United Mexican States
and the United States met in Monterrey, Nuevo Leon, Mexico, to
discuss issues important to both countries. Each President was
accompanied by the heads of their respective environmental
authorities and discussions focused on concerns about the
environmental conditions along the U.S. - Mexican border.
One result of the Monterrey meeting was a joint communique that
included commitments and directives for cooperative activities in
response to these conditions. The Presidents agreed to direct
their respective environmental authorities (the Ecological Sub-
Secretariat of the Secretariat of Urban Development and Ecology
(SEDUE)(SEDUE was reorganized and merged with SEDESOL - Secretary
of Social Development - in May 1992) of Mexico and the U.S.
Environmental Protection Agency (EPA), to jointly develop a
comprehensive border environmental plan designed to solve
environmental problems in the border area.
In February 1992 the Integrated Environmental Plan (IBEP) for the
U.S. - Mexican Border Area was released to the public. The scope
of the plan is such that the activities specified represent a
series of actions designed to ultimately achieve environmental
results along the border.
In response to the ground water protection concerns referenced in
the IBEP, the EPA, Region 6, established the Ground Water
Protection Sub-group to address its unique ground water concerns.
The sub-group is chaired by EPA Region 6 Office of Ground Water
Chief and is composed of representatives from the Texas Natural
Resource Conservation Commission (TNRCC), New Mexico Environment
Department (NMED), Texas Water Development Board (TWDB), Texas
General Land Office (TGLO), Texas Bureau of Economic Geology
(TBEG), U.S. Section of the International Boundary and Water
Commission (U.S. Section - IBWC), and the U.S. Geological Survey
(USGS) (see Appendix 4 for membership list). The charge given to
the sub-group included:
1.	Serve in an advisory capacity to the Water Work
Group
2.	Answer directly to the Water Work Group
3.	Limit activities to implementation of ground water
protection elements of the IBEP Phase I (FY92-94)
4.	Hold meetings quarterly, at a minimum
5.	The sub-group will geographically target the
vulnerable Hueco and Mesilla Bolson aquifers in the
El Paso/Ciudad Juarez area
2

-------
IBEP Phase I addresses several aspects of environmental protection
in the border area. The specific ground water protection concerns
mentioned in the plan are listed below and are the objectives of
the sub-group:
1.	Based on data obtained from appropriate authorities
in each country, develop an inventory of the ground
water sources, and quality for the sister city
communities which will include an area within 100
kilometers on each side of the border
2.	Exchange information on ground water protection
programs (ie., Underground Injection Control
program, Underground Storage Tank program, and the
Wellhead Protection program)
3.	Through monitoring programs, identify areas where
any transboundary ground water source or any
potential transboundary ground water source of
drinking water is contaminated or where there is an
identifiable threat of contamination to these
sources of water
4.	Advise the Water Work Group and develop cooperative
programs for solving identified problems under
existing U.S. - Mexican agreements
ADMINISTRATIVE CONSTRAINTS
The scope of the Sub-group was geographically limited to the Hueco
and Mesilla Bolson aquifers in the El Paso/Ciudad Juarez area. The
work accomplished by the Ground Water Protection Sub-group during
FY93 and for the remainder of FY94 will establish the foundation
for future tasks during Phase II (FY95 - FY00), which should
include other areas of border region. This work has also added to
our awareness of related administrative issues that must be
addressed if the specific recommendations are to be effective and
limited resources are to be efficiently expended to meet the
objectives of the IBEP and to enhance ground water protection
throughout the border region. The following discusses key
administrative issues and recommends to other U.S. Federal and
State agencies several specific activities that should be advanced
during the 1995 - 2000 time frame. The recommendations for
specific activities are related back to the four objectives that
were defined for the Ground Water Protection Sub-group.
1. Coordination
The Ground Water Protection Sub-group has been involved in the
successful implementation and coordination of several ground water
protection programs in the El Paso/Ciudad Juarez area, and based on
this experience recommends that such efforts be expanded to other
3

-------
areas along the U.S./Mexico Border.
Mandated responsibilities for state, local, and federal agencies
result in a distribution of environmental and water resources work
to many entities. In many cases, a common information base could
serve the management and planning responsibilities of multiple
agencies. There is a need for increased coordination of ground
water protection activities both within and among the many federal
agencies, state agencies, university researchers, and private
sector companies along the U.S. side of the border. Duplication of
effort should be avoided and successful projects should serve as
templates for programs in other areas. Uniformity in approach is
desirable as long as flexibility is encouraged to meet area-
specific conditions.
2.	Prioritization of Activities
In the U.S., priority should be given through a risk-based approach
to those areas where human health or ecosystems are presently
imperiled or threatened. In general, the major population centers
are coincident with the most pressing concerns about ground water
protection.
3.	Information Management
Enormous quantities of data of diverse and unknown quality from
many sources currently exist; additional large data sets will be
generated in the future. The Water Work Group should consider a
process where international linkage and electronic access to data
and to the actual data in the agreed upon format can be achieved.
GIS technology should be used to facilitate data management.
4.	Resources
Within the U.S., a comprehensive approach to address current ground
water quality problems and to avert anticipated future problems is
needed. The Sub-group recommends that a process be developed to
effectively and efficiently focus resource allocations to the
identified problem areas.
RECOMMENDATIONS AND FUTURE PROGRAM ACTIVITIES
Sufficient collection, synthesis, and analysis of multi-attribute
data sets is important to ground water protection strategies and
supports related environmental baseline initiatives and policy
decisions. EPA Headquarters' border GIS systems catalog developed
during IBEP Phase I is the initial step in this effort. The Sub-
group recommends to the U.S. Federal and State agencies that the
systems catalog be expanded to include a database inventory of the
systems. It is also important that this effort be international in
scope and that compatible data sets be developed for the border
area of both United States and Mexico.

-------
Characterization of shared ground water resources throughout the
border area, with special emphasis on those used by the major
population centers is needed. Aquifers used by small communities
may also be at risk as may be the ecosystems that depend on
discharge from aquifers. Characterization forms the scientific
basis for problem recognition, remediation, and policy
implementation.
Characterization of the ground water resource involves many
activities. In an effort to provide a basis to recognize and
document ongoing activities which apply to an overall ground water
program and to identify those activities which require priority
consideration as information may be lacking, the matrix of program
activity versus border segment has been developed (table 1).
Initially, a collaborative effort involving a literature and data
availability review should be conducted for the entire border area.
The Ground Water Protection Sub-group has completed the "Selected
References with Abstracts for the El Paso Region" (Appendix 1) for
the El Paso/Ciudad Juarez area to serve as an example of how the
product would appear in final form. Given the availability of this
information, agencies will be in a position to plan more responsive
and cost effective, collaborative programs.
In the U.S., ground water protection is far reaching and no one
agency or sector of the technical, regulatory, or policy community
can address it comprehensively. New alliances and consortia of
people (federal, state, local government, university, and private
sector) with relevant expertise must be promoted to address this
issue. The framework established under IBEP Phase I should be
continued to facilitate and coordinate critical activities. There
are many needs and limited resources; however, pollution prevention
has proved to be more cost effective than remediation activities.
For ground water protection efforts to be effective, they should
anticipate and avert potential problems. The development of the
Border Area is placing great stress on aquifers that are currently
highly developed and will impact other aquifers as additional
population and industry are attracted to the region. The problems
(quality, quantity, and impacts on ecosystems) associated with
development of new ground water resources and the increased
production from currently utilized resources can be anticipated if
the appropriate data are collected and analyzed. The Sub-group
recommends to the Water Work Group that studies be conducted that
could contribute to an environmental baseline to facilitate
technical and policy decisions.
The Ground Water Protection Sub-group recommends that the Sub-
group, or its equivalent, be continued to provide technical
assistance to the Work Groups established by the La Paz Agreement.
The Sub-group could assist in the dissemination of technical
information and provide a vehicle for the coordination of border

ground water related activities.
The membership of the Ground Water Protection Sub-group should be
expanded to include representatives of the Mexican government. A
binational coordinated effort at the Sub-group level could serve as
an important role for coordination of border area activities. Such
a coordinated effort vould enhance efficiencies and avoid
redundancy.
GROUND WATER PROTECTION SUB-GROUP OBJECTIVES ASSESSMENT AMD
IDENTIFICATION OF BORDER AREA GROUND WATER PROTECTION PROGRAM GAPS
Within the framework of the IBEP - Phase I report, specific
responsibilities were delegated to the Ground Water Protection Sub-
group. The Sub-group has meet the responsibilities within existing
budgetary and institutional constraints; however, some are beyond
the control of the Sub-group membership. With regard to the four
specific objectives listed for ground water protection in the IBEP
- Phase I report, the following is submitted.
Objective #1: Based on data obtained from appropriate authorities
in each country, develop an inventory of the ground water sources,
and quality for the sister city communities.
Assessment: The Sub-group has focused its efforts on the sister
city communities of El Paso and Ciudad Juarez during IBEP - Phase
I implementation. As evidenced by the selected references for the
El Paso region (Appendix 1), a number of studies of the ground
water resources in the border region already exist for the
Texas/Mexico/New Mexico area. However, some of these studies are
dated and are based on information of unknown quality, and the store
recent studies lack a comprehensive approach to defining the ground
water resources for the El Paso/Ciudad Juarez area.
Need: There is a need to identify all ground water bearing units,
quantify the natural and induced chemical quality of each aquifer,
characterize and quantify the current and prospective use and
available supply of each aquifer, and determine the direction of
ground water flow and its relationship to the flow of the Rio
Grande/Rio Bravo along the U.S./Mexico border. An extensive
literature search could serve to update the current reference
materials available for the El Paso/Ciudad Juarez area. The Sub-
group is recommending that a study be funded and that companion
studies commence for the El Paso/Ciudad Juarez region including New
Mexico and Mexico during IBEP Phase - I.
Objective #2: Exchange information on ground water protection
programs (ie., Underground Injection Control program, Underground
Storage Tank program, and the Wellhead Protection program).
Assessment: The Sub-group has devoted a considerable amount of
time and effort toward meeting this objective. The accomplishments
6

-------
section of this report highlight some of the activities undertaken
by the Sub-group.
Meed: There is a continuing need to maintain a free and open line
of communication with the Mexican government for the exchange of
information on ground water protection programs. The Sub-group
recommends that the Sub-group, or its equivalent, be continued to
provide technical assistance and coordination for border ground
water related activities.
Objective #3: Through monitoring programs, identify areas where
any transboundary ground water source or any potential
transboundary ground water source of drinking water is contaminated
or where there is an identifiable threat of contamination to these
sources of water.
Assessment: Through coordination with the U.S. Section of the
IBHC, ground water resource information may be obtained from the
Mexican government. However, the process is involved and the speed
at which information is being received from the Mexican government
has impeded the Sub-group's efforts at identifying areas where any
transboundary ground water source or any potential transboundary
ground water source of drinking water is contaminated or where
there is an identifiable threat of contamination to these sources
of water for the Mexican side of the border in the El Paso/Ciudad
Juarez area. The Sub-group has made some limited progress in
obtaining ground water information from the Mexican government by
working closely with the U.S. Section of the 1BWC.
Meed: The Ground Water Protection Sub-group is recommending that
the Water Work Group support/continue efforts in obtaining
published ground water information from the Mexican government by
encouraging the Mexican government officials on the Water Work
Group to provide ground water information in a timely manner.
Objective #4: Advise the Water Work Group and develop cooperative
programs for solving identified problems under existing Mexican -
U.S. agreements.
Assessment: Colonias located in the El Paso County area of the
border region represent a significant potential source of
contamination to the transboundary aquifers underlying the El
Paso/Juarez area. A particular concern for the quality of ground
water in these areas stems from the fact that improperly
constructed onsite wastewater treatment facilities are in use.
Federal financial assistance in the form of grants and loans to the
residents of these colonias is being made available through EPA,
States, and other U.S. federal agencies to install access to public
Water Supplies and wastewater treatment facilities. The improperly
constructed onsite wastewater treatment systems and improperly
constructed domestic water supply wells are not being required to
be decommissioned as a condition for federal financial assistance
7

-------
and remain a source of potential contamination of the ground water.
Meed: The Ground Water Protection Sub-group is recommending that
when State Revolving Fund dollars and federal financial assistance
are provided to individual households; riders be attached to the
financing agreements whereby existing shallow water Bupply wells
must be pulled and septic systems/cesspools/privies must be
properly decommissioned. The Ground Water Protection Sub-group
further recommends that the Texas and New Mexico Colonias Sub-
groups and the Drinking Water Sub-group of the Water Work Group
promote concurrent development of wastewater treatment systems with
the provision of public water supplies to avoid stressing existing
household septic systems and creating additional or exacerbating
existing ground water contamination.
THE INTERNATIONAL AGREEMENT PROCESS
The International Boundary and Water Commission (IBWC), in
accordance with the 1944 Water Treaty, is an international body
composed of a United States Commissioner and a Mexican
Commissioner. Each Commissioner heads the national section of
his/her respective country. Each Section is organized independent
of the other. Each Section deals with its own country's
authorities at the various levels of government in its role of
ensuring that the rights and obligations its government assumed in
the boundary and water treaties are met. The IBWC provides the
United States and Mexico a binational institution that enables
application of the various boundary and water treaties and other
agreements by technical experts at the border where the solution to
a problem may be developed, leaving only the political
international agreement decision to the two capitals.
When a problem arises that falls within the jurisdiction of the
IBWC, the IBWC conducts investigations and make recommendations for
international solutions to the two countries. Those findings are
usually in the form of joint reports of the Principal Engineers of
each Section, prepared in English and Spanish, for consideration of
the IBWC. Often each Section, independent of the other, organizes
inter-agency task forces of technical advisors within their
respective country to provide them with technical expertise in
resolving a particular problem. In turn, the IBWC would make its
formal decision and agreement in the form of an IBWC "Minute". The
joint reports of the Principal Engineers are often included as part
of the Minute.
IBWC Minutes, are prepared in both English and Spanish. The
Minutes are signed by the Commissioners and attested by the
Secretaries. Within three days of signing, a Minute is sent to the
foreign offices of the two governments for approval. Once approved
by the two Governments, an IBWC Minute becomes a binding obligation
of each government and the respective Commissioners are charged
with its implementation either directly through each Section or in
8

-------
cooperation with other agencies in one country or the other under
the supervision of the IBWC. Unless expressed otherwise, the two
Governments have 30 days to approve a Minute. Should such an
expression not come in 30 days, the Minute enters into force at
that tine.
An IBWC Minute may be a detailed international agreement which
implements the specific terms of a boundary or water treaty or it
may detail further implementation of an earlier JBWC Minute. An
IBWC Minute may also be an interpretation of a not so specific term
of a treaty provision that arose from application of that treaty.
INFORMATION MANAGEMENT
Many ground water studies have been conducted in the border region
that can be used as the basis for beginning the process of
characterizing the aquifers of the area. The Sub-group has
compiled a comprehensive list of these studies in the £1
Paso/Ciudad Juarez areas in an attempt to identify the references
available for developing an inventory of the region's ground water
resources and for characterizing the transboundary ground water
resources of the region. The 34 selected references include 12
State publications, 14 U.S. Geological Survey publications, 4
State/U.S. Geological Survey publications, and 1 each for the
Bureau of Reclamation, International Boundary and Water Commission
on the University of Texas. The list of references is included in
this report as Appendix 1.
In addition to the indexing of border ground water studies, the
Sub-group sought to develop a ground water data dictionary for the
El Paso/Ciudad Juarez area. Early in the process of developing the
dictionary, the Sub-group discovered that EPA Headquarters had
committed funds toward developing a Border Geographical Information
System Catalog that identified twenty-six (26) systems in the
Border region. Since the two efforts sought to achieve the same
objectives, the Sub-group refocused its efforts to support and
enhance the EPA Headquarters initiative. EPA's technical
assistance document entitled, "Water-Related GISs (Geographical
Information Systems) Along the United States-Mexico Border", is
included in this report as Appendix 3.
In order to facilitate the exchange of ground water quality
information between the United States and Mexican governments, the
Sub-group developed a standard format that could be used by both
countries. The format is designed to be consistent with EPA Order
7500.1A, Minimum Set of Data Elements for Ground Water Quality and
is included with this report as Appendix 3.

ACCOMPLISHMENTS
The following activities have been accomplished by the Sub-group
since its organization:
•	The Ground Water Protection Sub-group has net six
times (7/27/92, 9/22/92, 2/9/93, 5/4/93, 8/19/93, and
2/3/94) and has held two conference calls,
•	The Sub-group participated with an EPA Headquarters
(Office of Water - Municipal Support Division)
contractor (Vigyan, Inc.) for the development of a
catalog of Geographic Information System applications
for the water environment in the U.S./Mexico border
area. The first edition of the catalog was released on
October 14, 1993.
•	The Sub-group provided National Wellhead Protection
program guidance, technical assistance documents, and
the El Paso Ground Water Protection Strategy to the
Chair of the Water Work Group to send to the Mexican
government.
•	FY92 Wellhead Protection Demonstration grant funds have
been awarded to the El Paso City/County Health and
Environmental District ($39,500 Federal, $2,600 Local
match) for the expansion of the City of El Paso's
Wellhead Protection (WHP) throughout El Paso County.
Data gathered by the project will be entered into the
Region 6 GIS.
•	FY92 Wellhead Protection Demonstration grant funds have
been awarded to the City of Las Cruces, New Mexico
($39,500 federal, $2,500 local match) to implement a
WHP for the City's public water supply wells. The
information gathered by the project will be entered
into the Region 6 GIS.
•	EPA Region 6 is funding through TNRCC a Wellhead
Protection Demonstration Project for Ciudad Juarez,

the GWCAB.
TEXAS NATURAL RESOURCE CONSERVATION COMMISSION (TNRCC)
The TNRCC conducts various ground water protection programs that
focus on both prevention of contamination and remediation of
existing problems through education, permitting, and enforcement.
As the state lead agency for water resources, the TNRCC has to
administer both state and federally mandated programs including,
the Resource Conservation and Recovery Act; the Comprehensive
Environmental Response, Compensation and Liability Act (also
referred to as the Superfund program); the Clean Water Act; and the
Safe Drinking Water Act. The agency recognizes the special
problems associated with the border and has created an Office of
Border Affairs to act as a central contact point for activities.
The Office of Waste Management and Pollution Cleanup conducts the
following ground water related programs: The Petroleum Storage Tank
Division regulates underground and above ground product storage
tanks and requires ground water monitoring and remediation at
contaminated sites. The Industrial and Hazardous Waste Division
has responsibility for preventing contamination and insuring
remediation at industrial sites through the waste disposal facility
permitting and enforcement programs, underground injection control
programs, and uranium and radioactive waste disposal programs. The
Municipal Solid Waste Division monitors activities associated with
the collection, handling, storage, processing, and disposal of
municipal solid waste to ensure protection of ground water) and
requires remediation where these activities have failed. The
Pollution Cleanup Division is responsible for both Federal and
State Superfund activities and conducts remedial investigations and
seeks funding for remedial activities based upon a health risk
ranking program.
The Office of Water Resource Management conducts the following
ground water related programs. The Watershed Management Division
is responsible for chairing the Texas Groundwater Protection
12

-------
Committee and is also responsible for surface and ground water
quality management and planning programs and implementation of the
ground water nonpoint source pollution program. This division is
also responsible for ensuring that ground water resources are
protected during permitting and enforcement activities related to
municipal and industrial wastewater treatment and the Class V
underground injection well program. The Agriculture and Rural
Assistance Division is responsible for protecting ground water
resources by permitting confined animal feeding operations and
conducting the Wellhead Protection Program, On-site Waste Water
Program, and the Water Well Drilling Program. The Water Utilities
Division monitors public water systems for compliance with state
drinking water standards.
The Field Operations Division of the Office of Legal Services and
Compliance is responsible for the field investigation of
contamination complaints and the inspection of permitted and non
permitted facilities.
Section 26.403 of the Texas Water Code creates, the Texas
Groundwater Protection Committee as one means of bridging the gaps
in existing state ground water programs and optimizing quality
protection and improved coordination among agencies involved in
ground water related activities. The TNRCC was designated as the
lead agency for the committee and is responsible for administering
the activities of the committee. The committee meets once a
quarter and has a membership composed of representatives of the
following state agencies: Texas Natural Resource Conservation
Commission, Texas Water Development Board, Railroad Commission of
Texas, Texas Department of Health, Texas Department of Agriculture,
Texas State Soil and Water Conservation Board, Texas Alliance of
Groundwater Districts, Texas Agricultural Experiment Station, and
the Bureau of Economic Geology of the University of Texas at
Austin.
Major responsibilities of the Committee are to improve interagency
coordination in the area of ground water protection; to provide
recommendations to the Legislature regarding new protection
programs; to publish an interagency ground water monitoring and
contamination report; and to develop, implement and update a
comprehensive State ground water protection strategy. Recent focus
of the Committee's activities has been the development of a
nonpoint source pollution management program for ground water,
development of an Agriculture Chemical State Management Plan, and
the coordination and enhancement of the various ground water data
bases maintained by the member agencies. The focus of the
Committee's and the State's efforts over the next two years will be
the development of a comprehensive ground water protection program.
13

-------
MEW MEXICO ENVIRONMENT DEPARTMENT (NMED)
NMED will coordinate the Ground Water Protection Sub-group's
activities through its New Mexico Water Quality Control
Commission's Ground Water Protection Planning Committee, which it
chairs. The Committee includes representatives from the following:
State Engineer's Office, Energy Minerals and Natural Resources
Department, Game and Fish Department, Bureau of Mines, Department
of Agriculture, and a citizen representative.
TEXAS WATER DEVELOPMENT BOARD (TWDB)
The TWDB is responsible for financial assistance and planning
recommendations for water resource facilities and policies in
Texas. The Board issues State funds in the form of loans and
grants for financing water supply and wastewater treatment
facilities, flood control projects, agricultural water
conservation, colonia assistance, water supply research, and other
water related programs. The Board is also responsible for
forecasting and planning the State's water needs for the next 50
years. This function requires a significant level of data
collection, evaluation, and monitoring of the water resources
throughout the State.
In the El Paso region, the TWDB is currently: (1) providing
financial assistance for the construction of additional water and
wastewater treatment facilities, (2) identifying and providing
financial assistance to numerous economically distressed areas
(colonias), (3) providing technical assistance in long range
planning activities, (4) cooperating in water-level and water-
quality monitoring efforts, and (5) providing hydrogeologic
evaluations of the aquifers within the region.
The TWDB coordination mechanism includes water-level and water-
quality monitoring of the aquifers in the border region and is
primarily a function of the El Paso Water Utilities and Public
Service Board, the U.S.G.S., and the TWDB. Monitoring data is
incorporated into the TWDB ground water database and is used in
water planning studies and activities. The TWDB is also active in
the State's Ground Water Protection Committee.
INTERNATIONAL BOUNDARY AND WATER COMMISSION (IBWC)
The United States and Mexico have long recognized their shared
interests in the border environment. The two countries have been
involved in formal cooperative efforts related to the use of the
border's waters for almost one hundred years.
14

-------
During the 19th century, the Rio Grande and Colorado River
periodically changed course, causing uncertainty in both countries
as to the precise location of the border. The response, Mexico and
the United States signed a convention in 1889 creating the
International Boundary Commission, consisting of a Mexican and a
U.S. Section, to resolve boundary location issues related to
movements of the Rio Grande and Colorado River.
In 1944 the two countries agreed by treaty to create a new IBWC,
extend its authority to the land boundary, and give it lead
responsibility for border water sanitation project's mutually agreed
to by both countries. Consequently, in addition to its other
duties, the IBWC currently is involved in the planning,
construction, operation, and maintenance of several wastewater
treatment plants in the border area.
In 1983 joint U.S. - Mexican environmental activities in the border
area were formalized with the signing of a comprehensive Border
Environmental Agreement. This agreement defined the border area as
a 100-kilometer wide zone on either side of the political boundary,
and it established a general framework in which both countries
agreed to prevent, reduce, and eliminate sources of air, water, and
land pollution.
In particular, the 1983 agreement outlined procedures for
establishing technical annexes under which specific projects are
carried out. Five annexes are currently in force:
•	Annex I: Provides for the construction and operation
of Tijuana/San Diego wastewater treatment facilities.
•	Annex II: Authorizes the establishment of the Inland
Joint Response Team (JRT) to respond to accidental
spills of oil and hazardous substances in the border
area.
•	Annex III: Establishes procedures governing the
transboundary shipment of hazardous wastes and
hazardous substance.
•	Annex IV: Requires copper smelters in the border area
to comply with certain emission limits.
•	Annex V: Provides for an assessment of the causes of,
and solution to, air quality problems in sister cities
in the border area.
Four binational work groups have been working since 1983 to
implement the terms of the agreement and its technical annexes.
Those four workgroups, which address air, water, hazardous waste,
and emergency response issues, currently are involved in a number
of projects in the border area.

-------
U.S. GEOLOGICAL SURVEY (USGS)
The mission of the Water Resources Division, which supports the
overall mission of the U.S. Department of the Interior and the U.S.
Geological Survey, is to provide the hydrologic information and
understanding needed for the best use and management of the
Nation's water resources for the benefit of the people of the
United States.
To accomplish its mission, the Water Resources Division in
cooperation with State and local governments and other Federal
agencies:
•	Systematically collects data needed for the continuing
determination and evaluation of the quantity, quality,
and use of the Nation's water resources.
•	Conducts analytical and interpretive water-resources
appraisals to describe the occurrence, availability,
and physical, chemical, and biological characteristics
of surface and ground water and their inter-
relationship.
•	Conducts supportive base and problem-oriented research
in hydraulics, hydrology, and related fields of science
and engineering to improve the basis for field
investigations and measurement techniques and to
understand hydrologic systems sufficiently well to
predict quantitatively their response to stress, either
natural or manmade.
•	Disseminates water data and the results of
investigations and research through reports, maps,
computerized information services, and other forms of
public releases.
•	Coordinates the activities of Federal agencies in the
acquisition of certain water information.
•	Provides scientific and technical assistance in
hydrologic fields to State, local, and other Federal
agencies, to licensees of the Federal Energy Regulatory
Commission, and, on behalf of the U.S. Department of
State, to international agencies.
•	Acquires, develops, and disseminates information on
water-related natural hazards such as droughts, floods,
landslides, land subsidence, mudflows, and volcanoes.
16

-------
•	Administers the provisions of the Water Resources
Research Act of 1984, which include the State Water
Resources Research Institutes and the Research Grants
program.
•	Supports the provisions of the National Environmental
Policy Act of 1969 and manages Geological Survey
conduct of natural-resources surveys in response to the
Comprehensive Environmental Response, Compensation, and
Liability Act (Superfund Act) of 1980.
Authority for carrying out this mission is derived from legislation
of 1879, which created the Geological Survey, and legislation of
1888 and 1894, which provided for gaging of streams and determining
the Nation's water supply. Congressional appropriations have been
made annually since 1894 for gaging streams and performing other
functions relating to water resources. In 1964, the Office of
Management and Budget broadened the U.S. Geological Survey's
mission to include the role of lead agency for the coordination of
Federal water information programs. This responsibility was
reaffirmed most recently by the Office of Management and Budget
memorandum 9201 on the coordination of water information.
General direction of the Division's field program is through four
Regional Hydrologists, each of whom is located at a regional center
— Reston, Va. (Northeastern Region); Norcross, Ga. (Southeastern
Region); Lakewood (Denver) Colo. (Central Region); and Menlo Park,
Calif. (Western Region).
Each region consists of several States, and each Regional
Hydrologist, with authority from the Chief Hydrologist, is
responsible for the water-resources programs and projects conducted
by the District offices within the region. The Regional
Hydrologist also represents the Chief Hydrologist in negotiations
and dealings with other organizations and committees on matters of
concern to the Division. Regional Hydrologists are assisted by
Area Hydrologists who are responsible for coordinating management
activities among several Districts.
Field operations are conducted through 48 District offices, each
headed by a District Chief. These offices generally are located in
State capitals, and their jurisdictional boundaries correspond to
State boundaries. Each District typically has one or| more
subdistrict and field offices that report to the District Chief.
There are three multi-State Districts — New Hampshire-Vermont,
Massachusetts-Rhodes Island, and Maryland-Delaware-D.C. — that
have offices that coordinate programs within each state and report
to the District office. Each District Chief is responsible for the
planning, programming, and implementation of water-resources
investigations within the District.

BUREAU OF ECONOMIC GEOLOGY -
THE UNIVERSITY OF TEXAS AT AU8TIN (TBEG)
The TBEG functions as the geological Burvey of Texas and is a
research unit of The University of Texas at Austin. The Bureau has
conducted studies of the geology and hydrogeology of the Border
Area for many years and is capable of supporting the Ground Water
Protection Sub-group through geologic and hydrologic investigations
that will provide a further understanding of the processes that
impact the availability of safe drinking .water supplies,
remediation of contaminated ground water, and the geologic
framework of ground water resources. Investigations of such issues
as impacts of aquifer systems, hydrochemistry, vadose zone
processes, aquifer heterogeneities, and recharge and discharge
processes are among the many topics that are important to ground
water protection. The Bureau has special expertise in arid zone
systems and the interplay between surface water bodies and ground
water resources. The Bureau is also active in the State's Ground
Water Protection Committee.
P.fl./MEXICO BORDER INITIATIVE'B INTEGRATION
WITH THE
COMPREHENSIVE STATE GROUND WATER PROTECTION PROGRAM (CSGWPP1
New Mexico and Texas State agencies with ground water protection
responsibilities are represented on the Sub-group. Activities of
the Sub-group are reviewed by each member to assure that actions
and recommendations are consistent with their respective CSGWPP.
State agency program requirements are presented to the Sub-group
during the planning of projects.
Resources in the form of personnel and assistance funding represent
the greatest barrier to integrating these two activities. Some
State agencies fail to attend Sub-group meetings due to the lack of
adequate travel funds. Financial assistance is needed to provide
cooperative agreement funding to the States along the border and
for administrative and programmatic support by the EPA Regions.
ACTIVITIES FOR THE BALANCE OF FY94
Highlights of activities planned by the Sub-group for the second
half of FY94 are as follows:
• Based on information obtained from the appropriate
authorities in the U.S. and Mexico, the Sub-group will
continue to work with the Mexican government through
IBWC in developing an inventory of the shared ground
water sources and ground water quality for the sister
cities of El Paso, Texas, and Ciudad Juarez, Chihuahua.
This information will be digitized and entered into the
Region 6 GIS database and made available to other
Federal, State, and local governments.
18

-------
•	Based on ground water quality monitoring data gathered
from the appropriate authorities in the U.S. and
Mexico, the Sub-group will continue to identify areas
where any transboundary ground water source or any
potential transboundary ground water source of drinking
water is contaminated or where there is an identifiable
threat of contamination to these sources of water.
•	The Sub-group will participate as appropriate in the
development of the U.S./Mexico Border Action Plan
(Second Stage Plan, 1995 - 2000) during FY94.

ACKNOWLEDGMENTS
Production of this catalog was made possible through the
enthusiastic participation and generous contributions of time, talent,
and knowledge by the organizations who submitted information on
their own geographic information systems (GISs) for the catalog.
Especially noteworthy are the interest and commitment
exhibited by the GIS coordinators and others who serve as GIS
contacts for the participating organizations. These individuals, many
of whom are identified in the catalog entries, represent a substantial
intellectual and economic investment in water-related GIS information
by catalog contributors. Most are from academic institutions,
government agencies, advocacy groups, and the corporate sector.
Catalog participants have helped identify a significant
collection of GIS resources available to communities or organizations
seeking to alleviate the serious environmental problems that exist
along the United States-Mexico border. We appreciate their
cooperation and valuable contributions.

The GIS Catalog
and the
United States-Mexico Border
Geographic Information System (GIS)
Catalog
This catalog identifies 26 existing or proposed
geographic information systems (GISs) that
contain information on the water environment
within 100 kilometers (about 62 miles) of the
U.S.-Mexico border. The catalog is part of an
effort by governments and communities on
both sides of the border to better manage their
water resources as called for by the February
1992 'Integrated Border Environmental Plan for
the MexicarvU.S. Border Area' The Plan was
issued jointly by the Secretaria de Desarrollo
Urbano y Ecotogia (SEDUE) of Mexico and the
U.S. Environmental Protection Agency. The
GIS catalog aims to provide a ready reference
for GIS system developers and users at all
levels of government and the private sector in
both the United States and Mexico.
The Need for GIS Information Along the
Border
The catalog responds to the need voiced by
water program managers and staff of both
countries to share GIS information that can
help solve environmental problems existing
along the border. GIS allows information
extracted from various existing databases to be
combined to produce valuable new information
formatted and displayed for quick
comprehension in a way which GIS has made
economically feasible for the first time. This
new data can not only visually demonstrate
relationships between complex environmental
problems but also can help point the way to
optimal solutions. Typical GIS outputs are
maps, charts, graphs, tabular listings, and
surface models.
What Is a GIS?
Managers and technical staff who have created
GISs express strong support for GIS as a
decisionmaking and planning tool. A
geographic information-system Is a
computerized database management system
that has a unique ability to link, integrate, and
visually display information contained in
numerous disparate databases. It allows
capture, storage, retrieval, analysis, and
display of spatial (locationally defined) data. It
consists of hardware, software, data, and an
organizational framework of people and
organizations. GIS technology bridges the
disciplines of computer science, information
management, and cartography. GIS data may
come from sources as diverse as maps, aerial
photographs, and satellite imagery to
socioeconomic, census, meteorological, and
crop records.
GISs and Water Quality
Among GISs described in the catalog are
projects either developed or in progress by
State, Federal, and local agencies; educational
institutions; advocacy groups; and the private
sector. Much of the information these systems
contain is useful to such water-related activities
as managing point and nonpoint pollution,
evaluating management alternatives for local
water use planning and zoning, and modeling
the effects of existing and proposed activities
on water quality.

Catalog Organization
GIS Descriptions. The catalog contains a one-
page description for each of the 26 GISs listed.
Entries are listed alphabetically according to
the State/country where the GIS is physically
located. This location is indicated in the upper
right hand comer of each entry. The State or
country names appearing in parentheses
below the top line in the upper right corner
represent the areas of geographic coverage for
that entry.
Matrix Showing Geographic Coverage.
Following this page and before the individual
GIS listings is a matrix that summarizes the
coverage of each entry according to
geographic region from west to east along the
border; that is, from the Baja,
California/California region to the Gulf of
Mexico.
Attachments. Some organizations submitted
supplemental material that more fully explains
their systems. This material is presented
under the •ATTACHMENTS' section at the end
of the catalog.
Catalog Is Preliminary Effort ~
The purpose of this catalog is to provide a
preliminary list of water-related GISs that
pertain to features along the border. It should
acquaint GIS developers and users with
information on some existing systems identified
by various organizations that either have GISs
or may want to develop'them.
The goal is to help water program managers
and staff access valuable and dynamic
information as they strive to develop or
upgrade their own programs. It may help them
decide whether to introduce a GIS component
into their current projects. It may help them
determine whether a GIS exists that can serve
as a model they can adapt to their own
systems or needs. Or it may help them
discover that a GIS already exists on a subject
they had planned to pursue. A further goal is
to stimulate the information sharing and
people-to-people networking that help assure
the best use of scarce resources for all those
working to improve environmental conditions
along the U.S.-Mexico border.

COMMENTS (System Originator):
*GIS has been beneficial to data integration, data visualization, conflict identification, and the ability
to ask previously impossible questions. The largest problem has been the cost and quality of data
Both scale and accuracy are highly variable and range from 1*« 100* to V«24,000". Many
questions remain regarding the accuracy of data that we did not build. Most databases in use
today were not built with GIS in mind. In addition, a more detailed listing of data sets could be
useful in the future.'

COMMENTS (System Originator):
•GIS has been most valuable in the types of activities the RGIS program does. We have found
ARC/INFO to be to be a useful management and data conversion tooL It Is also a very powerful
spatial analysis tool and when combined with remote sensing technology we are able to provide
more indepth analysis for our clients. Some problems encountered have been lack of full
documentation, incompatible systems, and porting large data sets from a workstation to PCs. The
system is constrained in that most data sets are currently at a small scale and there is a lack of
good quality source data in both mapped and digital formats.'

COMMENTS (System Originator):
The 'Geographic Information System (GIS) Prototype Data Dictionary for Oil Spill Response
Activities' is a compilation of information on oil spill related data sets held by State and Federal
Agencies. The dictionary is an initial component in GLO's development of a GIS to support the
Statewide oil spill response and prevention program. It is designed to ensure proper
documentation of data acquired for the GIS and is a first step in the development of State GIS data
standards. Conducted between September 1,1991, and November 31,1992, with funding by the
U.S. Environmental Protection Agency and the Suae, the project received input from more than 52
individuals representing 19 organizations.
The dictionary describes the format, location, structure, and usage of 55 data coverages called
thematic layers.' Other information items include: 'Entity Reports,' which identify and define the
data elements in the thematic layer; 'Attribute Reports,' which describe attributes or characteristic
features of the data; and a list of Texas GIS contacts.*

COMMENTS (System Originator):
•Rapid growth on both sides of the international boundary makes a common information base
essential to managing both municipal and natural resources in a common geography.
Development of GIS capabilities at the twin-city scale is problematic with differences in information
quality, extent, and format between U.S. and Mexican sides. Building the street base tor Nuevo
Laredo in AutoCAD from existing hard-copy maps provided the first level for data exchange and
communication. We are using merged Landsat and SPOT imagery to complete the land use
classification and mapping of street networks and surface hydrology in the Nuevo Laredo Municipio.
The 1990 Mexican census tracts provide a comparative base for understanding infrastructure
service delivery at a city and neighborhood scale.' ATTACHMENTS: Nona

programs In remote sensing and geographic
Information systems, computer applications,
natural resource research, and environmental
analysis The rapid growth of these technolo-
gies often has adversely affected their success-
ful Integration Into routine management
operations and has created a gulf between
laboratory development and application to
actual problems The Arizona Remote Sensing
Center (ARSC), formed 20 yean ago. serves to
facilitate the integration of Information tech-
nologies in the routine management process by
responding to the real-world problems of
decision makers Scientists in ARSC are ac-
tively involved in the design, development, and
application of new technologies to respond to
today's global problems

Imaging amy and filter wheel to allow acquisi-
tion of accurate, narrow-band mul.tspectral
data. A bl-spectral multiplexing video camera,
developed by ARSC, allows for either real-time
or stored Image analysis When flown on light
aircraft, these systems allow for cost-effective
acquisition of highly accurate and repltcable
image data for automated mapping and monl-
-------
taring of renewable natural resources. In
conjunction with the aerial video systems.
ARSC operates a Trimble Global tosltlonlng
System (CPS) (or continuous mrievsl of

PRICE SHEET - AUGUST 1992
The Natural Diversity Data Base (NDDB) collects information-on the location and
condition of California's rare and threatened species and natural communities, and enters
these data into a computerized data management and mapping system. This information is
made available to interested parties for a fee in the form of computer printouts, map
overlays, and in computer files on disk or tape. The entire inventory can be purchased for
an annual subscription in the form of a microcomputer database application called RareFind.
RareFind provides a text based (no graphics) report for any of California's 2,800+, 1:24,000
scale quad maps (United States Geological Survey 7.5 minute maps).
The location for a single population or community stand is the basic unit of record in
this system. Product pricing is based on the number of records involved for a given-
retrieval. The NDDB uses a two-tiered pricing structure that affords a 50% reduction in the
per record cost for government agencies and private conservation organization! Private, for
profit organizations or individuals are charged the full rate. These rates are listed in the
following table.

Typical requests for information will usually involve a report and map overlay for a
single USGS 7.5' quad. The average quad in California has about seven (7) NDDB records.
The cost for such a retrieval would be calculated as follows:
We find that many of the requests we receive are for projects in the south coastal and
San Francisco Bay areas where we have records for many rare and threatened species and
natural communities. In these regions, the per request cost usually range between $140 and
S240 per quad. Text only requests will not include a separate charge for staff time unless an
inordinate amount of staff time is required due to the custom nature of the request.
We will charge 50% of the total cost for cancellation of orders that we have taken,
processed, but not yet delivered. Orders that have been delivered cannot be returned,
and no refund will be made.
We frequently customize products to meet the needs and desires of our customers. For
example, we can produce county specific data sets for use with our RareFind application.
We attempt to be flexible with product design and pricing to best serve the information needs
of the conservation and development communities.

TECHNICAL DESCRIPTION
HDDB-Oeogrephie Informstioa System
In 1989, the Department of Fish and Cane transferred the Natural
Diversity Data Base (NDDB) to a modern Geographic Information
System (CIS). The NDDB CIS is an integrated system of hardware,
software and data which is used to store and analyze information
about the geographic extent and condition of rare and endangered
species and communities in California.
The NDDB CIS uses Hewlett-Packard computers and HP-UX (UNIX)
operating system for its computing platform. The configuration
consists of a local area network (IAN) -of seven workstations which
are equipped with high-resolution color displays - and 8 to 32
megabytes of local RAM. Total disc storage space available on the
system is about 2.5 gigabytes. Peripheral devices include a
CalComp 36" color electrostatic plotter, one 3'x«' and four 2'x3'
digitizing tables, a high-speed line printer, laser printer, a tape
cartridge unit and a 6250 BP1 9-track tape drive.
The software used is a vector-based CIS called Genamap. a product
of Cenasys, Inc. of Fort Collins, CO. Genamap i6 closely linked
with the Oracle relational data base manager through the industry
standard, Structured Query Language (SQL) interface. Genamap is
used for the graphic and geographic functions, while Oracle handles
the extensive textual attributes. The system provides a variety of
tools for input, storage, manipulation and output of digital
spatial data. Data input is accomplished through digitizing
hardcopy maps, coordinate geometry (COCO), or importing existing
digital data. The graphic data are stored topologically within
Genamap as points, lines or areas. Each map feature is assigned a
"tag" value which is the key field used to link it to the textual
attribute data stored in Oracle relational tables. Typical
analyses include retrieval of species occurrences based on
geographic location, such as by 7.5' quad or a project area; or by
proximity, such as within two miles of a project area. The
attribute data can be used to narrow the search criteria using
thematic characteristics, such as species or listing status, in
addition to geographic criteria. The results of queries can then
be output using pre-formatted text reports or color maps.
In addition to rare species and natural community data, the JSIS
contains land ownership information and cartographic data such as
roads, streams, boundaries and Public land Survey System. The CIS
is also be used by the Significant* Natural Areas Program (SNAP) to
identify areas of significant biological diversity and toy Realty
Services to manage parcel information for DFG-owned lands.
For information regarding the CIS contact Tom Lupo, Geographer, at
(916)445-6264. For species data retrievals contact Nancy Vierra,
Information Services Coordinator, at (916)324-3812.

INTRODUCTION
The San Diego Association of Governments (SANDAG) is the regional planning agency and
"council of governments" for the San_piego region. This Association is governed by a
Board of Directors composed of an elected official from each of the region's 19 local
governments. Supplementing the voting members are advisory representatives from the U.S.
Department of Defense, the California Department of Transportation (CALTRANS), the San
Diego Unified Port District, and Tijuana/Baja California.
SANDAG's monthly Board of Directors meetings provide the public forum for significant
regional issues suctras growth, transportation, environmental management, housing, open
space, air quality, energy, fiscal management, economic development, and criminal justice.
Association Directors adopt plans, establish policies and develop programs for these regional
issues which are used by local governments and other public and private organizations.
As a result of the tasks carried out in the Overall Work Program and special projects for
member agencies, many data bases and an array of technical capabilities have been
developed. These, along with the staff that performs the processing and analysis of the
information, make up the Regional Information System. This report includes a discussion of
the major components of this system.
Access to information and services is available to SANDAG member agencies through the
Local Technical Assistance (LTA) program. SourcePoint, a non-profit corporation chartered
by SANDAG, was established to provide data and technical expertise to non-member public
agencies, the private sector, and the general public. Appendix A contains a list of data
reports and technical documentation that have been developed for some of the information
described in the "Data Bases" section of this report. Appendix B includes sample data
profiles used to summarize the information in tabular form. In most cases, these can be
produced for standard geographic areas (such as jurisdictions) as well as for user-defined
areas, such as facility service areas or marketing areas.

-------
COMPUTER HARDWARE AND SOFTWARE
SANDAG uses a Prime 9955 n minicomputer and Sun Spaicstations to perform the data
processing and geographic information systems (GIS) functions described in this report. Two
Calcomp 8-pen color plotters, one connected to the Prime computer and another connected to
a Sun Spaicstation, are used to produce all-color plots. Outside service bureaus are used to
provide electrostatic plotting services.
More than 80 PCs are maintained, with most connected through two Novell networks. In
response to the ever-increasing use of PCs in the workplace, SANDAG offers microcomputer
workshops free of charge to local agency staffs. The workshops, conducted twice a year,
include half-day sessions for spreadsheet (Lotus 1-2-3), wordprocessing, (WordPerfect) and
general PC skills at introductory and intermediate levels. Approximately 500 people attend
these workshops during each session.
The GIS used at SANDAG is ARC/INFO v.6.0, developed by ESRI of Redlands, California.
ARC/INFO is used to automate, manipulate, analyze and display geographic data. The
characteristics of the software include its modular design, its ability to integrate many types
of data, its utility for developing application-specific user interfaces with screen menus and
its programming language called Arc Macro Language (AML). ARC/INFO is structured to
accommodate various relational database management systems and can operate on many types
of computers with a variety of graphics hardware.
Using ARC/INFO, SANDAG has the ability to perform map digitizing and editing and
conduct analytical operations using map overlay and summary statistics procedures. Feature-
based editing is used to maintain and update the digital databases. Points, lines, areas, and
map annotation can be moved, copied, added, deleted, or reshaped using ARC/INFO.
Tabular attributes can be created and updated or transferred between features. The
cartographic production component of the software is used to produce a variety of map
products at SANDAG. Features from any number of map coverages can be selected for
display and drawn with different symbols.
ERDAS software provides image processing and raster geographic information system
capabilities. The ERDAS-ARC/info Live Link allows for the integration of vector data with
raster imagery. Additional software includes a Fortran compiler and SPSSx v. 3.1 for
statistical analysis.

DATA BASES
Historical, current, and projected data of many types are maintained as part of the Regional
Information System. Some are primary data bases, created by SANDAG specifically for use
in regional and local planning activities. Others axe secondary in nature, compiled from
outside sources.
In most cases, information from each data base is available in summary format in printed
reports, bulletins, or in computer-readable format (ASCII or Lotus 1-2-3 spreadsheet format).
Technical reports describing the methodology used to produce die data are also available for
some data bases. Appendix A lists the data and technical reports containing information
about the data described in this section; Appendix B provides examples of data profiles that
are available for selected data bases.
DEMOGRAPHIC AND ECONOMIC DATA BASES
Census
The census, conducted every ten years, provides the most detailed collection of demographic
data available. SANDAG/SourcePoint is designated as the Regional Census Data Center for
San Diego. As such, we are involved in pre-census planning activities, such as questionnaire
content development and the definition of census-related geographic areas, such as census
tracts and block groups. Once census data are released, we are the first in the region to
receive the data in computer-readable format and are able to make the information available
for in advance of printed reports distributed by the Census Bureau.
The most geographically detailed information comes from the "short form", or 100 percent
count questionnaire that all households received. This information, available down to the
census block level of geography, includes information about the population by ethnicity, age,
marital status, household composition, and housing information such as type, tenure,
occupancy status, value, and rent
Less geographically detailed but more comprehensive in terms of the information available is
data from the "long form", or sample questionnaire. This questionnaire was received by
about one out of six households and contains all of the short form questions as well as
additional questions about income, educational attainment, occupation, employment status,
ancestry, place of work, disability status, vehicle ownership, commute patterns, and length of
residency. This information is available down to the block group level of geography.

Since the DIME file's inception for the 1970 Census, SANDAG has updated and maintained
a street center-line data base, making the file an integral part of the regional information
system. The "enhanced DIME file" now includes 1990 Census geographic area information
from the TIGER file, shape nodes, zip codes, private roads and full county coverage.
There are two special files that are scheduled for release in 1993.' The first is the Census
Transportation Planning Package (CTPP). In this file census data are aggregated to special
transportation planning zones to provide demographic information and travel characteristics
about people at their place of work. The CTPP includes joumey-to-work data (including
origin and destination information) means of transportation to work, travel times, socio-
economic characteristics of workers, and other census information about persons and
households.
The second special file is the Public Use Microdata Sample (PUMS). PUMS files consist of
a sample of actual census records (stripped of name and address) that allow the user to
produce special crosstabulations of information, such as age of householder by household
income. Because of the small sample size of this file, the information is available only for
areas of 100,000 persons or more. There will be two PUMS files,'one a five percent sample
and the second a one percent sample. In San Diego, geographic areas in the five percent
sample file will be defined as 13 groups of subregional areas, with the population in each
group ranging from just over 100,000 to about 350,000. The one percent sample will also
have information for 13 areas, but those areas are defined as the four cities over 100,000 in
population (Chula Vista, Escondido, Oceanside, and San Diego), with the City of San Diego
divided into nine areas and a total for the remainder of the county.
Population and Housing Estimates
Population growth in the region is monitored through annual population and housing
estimates, developed in cooperation with local agencies and the California State Department
of Finance (DOF). The estimates provide intercensal estimates of the size and geographic
distribution of the population for jurisdictions and census tracts. The estimates use the
ccmsus as their base and are prepared using the "housing unit method", the most commonly
used technique for making subcounty population and housing units estimates. The
components of this method are total housing units, occupancy rates,average household size,
and the number of people living in group quarters (such as military barracks and college
dormitories.) Using building completion and demolition data and group quarters and
annexation information provided by local agencies, DOF produces annual estimates for each
jurisdiction. SANDAG then produces estimates at the census tract level that are controlled to
the jurisdictional totals. Every two years, the estimates are produced for very small

-------
geographic areas to allow for aggregation to user-defined and other non-standard geographic
areas.
Demographic Characteristics Estimates
While it is important to address planning issues on the basis of the overall change in
population size, changes in the characteristics of the population can be of equal or greater
significance. For example, changes in the age structure affect school, health care, and
marketing issues. Estimates of the population by age, racial/ethnic composition, and
household income are developed down to the census tract level of geography. The
demographic characteristics program has two purposes. The first is to provide current
information and update key trends in the region's demographic make-up. The second is to
analyze these changes and their impact on various planning issues in the region. These
estimates are produced every two yean.
Regional Growth Forecast
In cooperation with local jurisdictions, a forecast of population, housing, employment, and
land use is developed. The first step in the process is to develop a regionwide forecast. A
subregional forecast is then prepared based on the General/Community plans each jurisdiction
has in place at the time the forecast is produced. (See "Regional Growth Forecasting
Models" in the Models section of this report.)
The current subregional forecast, Series 7, portrays the likely timing and distribution of
future population, housing, and employment for the years 1995, 2000, and 2010. This
forecast is currently being updated in a cooperative effort between SANDAG and local
jurisdictions. The Series 8 Regional Growth Forecast uses the 1990 Census as the base and
will provide information for the years 2000, 2010, and 2015. For the first time, the
subregional forecast will include projections of the population by four ethnic groups, age,
and sex. The preliminary Series 8 subregional allocation is scheduled for release in the Fall
of 1992.
Criminal Justice Data
The Criminal Justice Research Division collects and maintains historic and current crime and
justice-related information from the region's ten local law enforcement agencies. Statistical
data, such as crimes and clearance rates by type of offense, characteristics of crimes and
victims, and offender characteristics are examples of the types of information available in
tabular and graph form.

EMPLOYMENT-RELATED DATA BASES
Employment Estimates
The 1990 Regional Employment Inventory is the most current compilation of site-level
employment statistics. The inventory reflects an estimate of average annual employment
(from the Economic Development Department) classified by industry at the place of work
and is comprised of three components: civilian wage and salary employment, self-employed
and domestic workers, and military employment. Since 1972, employment inventories have
been produced by SANDAG for use in transportation studies, public facilities analyses,
growth forecasts, and other applications. An historical series such as this allows for analysis
of regional employment trends in terms of type of employment, number and size of
employers, and geographic distribution. The Employment Inventory is updated every two
years.
Activity Centers
"Activity centers" are facilities and institutions that attract large numbers of people and
generate high volumes of vehicle trips on a regular basis. The 1990 Activity Centers
Inventory contains data on eight different types of facilities: major employers, office
buildings, industrial parks, government centers, shopping centers, hospitals, tourist attractors,
and schools. The location, size, number of employees, and date of establishment is
maintained for each facility. Each facility is given a unique identification number which
allows tracking over time even though the name or location may change. The information
can be used to evaluate the need for additional facilities, to perform transportation demand
analyses, assist in land use planning, and to monitor growth forecasts. The Activity Centers
inventory is updated every year.
LAND USE AND ENVIRONMENTAL DATA BASES
General and Community Plans
An important data base is developed as a direct result of the Regional Growth Forecast
process. This is a computer-readable file of General/Community plans, which contains
planned land use information for each jurisdiction. Information about lands constrained from
private development by policy, public ownership, or for environmental reasons is also
maintained. By performing a series of computer overlays of existing land use, planned land
use, and constrained lands, net developable acres by land use category can be tabulated and
mapped. Also maintained is a computer-readable file of each jurisdiction's Circulation
Element of the General Plan.

Land Use
The 1990 Land Use Inventory reflects land use patterns in the region as they were in June,
1990. The file was created using new technologies involving satellite imagery and change
detection procedures. Multi-date imagery, from 19S6 to 1990, were viewed simultaneously
to produce a composite image which highlighted arOs of change. Using the image as a
backdrop, new land uses were added to the file. Ancillary resources, such as color infra-red
photography, Thomas Bros, maps, USGS topographical mdps, the employment inventory,
and the activity centers data base were used to identify over 70 types of land-uses. A color
1" to 2 mile scale Generalized Land Use map is available that portrays 19 categories of land
use. The digital file can be used to tabulate and plot any combination of land uses. The
land use inventory is updated approximately every five years for use in the Regional Growth
Forecast and the Regional Transportation Plan.
Public Ownership
The 1990 Public Ownership File inventories lands owned by public agencies. Eleven
categories of federal, state and local agencies are contained in the data base. Information
was obtained from local jurisdictions, the County of San Diego Tax Assessor, and other
public agencies such as the California Department of Forestry, California Department of
Parks and Recreation, and water and school districts. The data base is updated
approximately every five years in conjunction with the Regional Growth Forecast.
Public Land Survey
The Public Land Survey, developed primarily by the U.S. Geological Survey, shows
township and range lines and the resulting sections and ranches in the region's land base
survey.
Steep Slopes
This data base identifies areas in the region with a slope of 25 percent or more. The original
mapped information was created by the U.S. Geological Survey using a photomechanical
process to translate the distance between contours into percentage slope. The digital data
base was created by electronically scanning the mapped information and converting it to
ARC/INFO format.

National Wetlands Inventory
The National Wetlands Inventory, developed by the U.S. Fish and Wildlife Service, contains
data on wetlands in the San Diego region. The information was collected in 1985 and
identifies over 140 types of wetlands. The classification system is hierarchical and structured
around a combination of ecological, hydrologicaTand substrate characteristics. The data base
contains wetland classifications for rivers, streams and creeks as well as for water bodies
such as lakes, lagoons, and bays.
Hydrography
The hydrographic data base contains streams and their direction of flow replicating the
stream drainage .patterns in the region. Digital files were obtained from the Teale Data
Center in Sacramento. The data base waS" developed in cooperation with the California
Department of Forestry and Fire Protection and is based on digital files from the U.S.
Geological Survey.
Important Farmlands
The State of California Department of Conservation Farmland Mapping and Monitoring
Program inventories important farmlands in the state. The data base contains information on
the location of prime and unique farmlands, grazing lands, and farmlands of state-wide or
local importance in the region. This information is updated every two years.
Agricultural Lands
Agricultural preserves and Williamson Act contract lands are included in this data base.
Land within agricultural preserves is classified into three land use categories-urban prime
(parcels located within three miles of cities of 25,000+ population), other prime, and
nonprime (grazing land, which is the major agricultural contract land in San Diego County).
Vegetation
Various efforts are currently under way to collect information on natural vegetation
communities and sensitive habitats in the San Diego region. These include the City of San
Diego's Clean Water Program Multi-Species Conservation Plan, the Metropolitan Water
District's Pipeline 6 study, and well as efforts by local agencies and the North County
Wildlife Forum. All of the vegetation and habitat data bases will be joined into one seamless
county-wide data base.

California Natural Diversify Data Base
The California Natural Diversity Data Base is a state-wide data base developed by the
California Department of Fish and Game. If contains information on rare, threatened or
endangered plant and animal sightings. SANDAG's version of the data base contains point
locations for species sightings within the San Diego region only. Although it is not a
comprehensive inventory of all rare plant and animal species, it provides historical-and
current information on sightings of rare plants and animals.
TRANSPORTATION-RELATED DATA BASES
Travel Behavior Survey
In 1986, a travel behavior survey was conducted of almost 3,000 randomly selected
households in the region. The two primary purposes of the survey were to obtain trip origin
and destination information and to determine travel patterns throughout the region. This
information is used to calibrate the trip generation, trip distribution, and mode split models
that are part of the regional transportation modeling package. For this survey, each
household member was asked to keep a trip diary of his or her travel during the assigned
travel day. This information included trip purpose, location, trip length, mode of travel, and
vehicle occupancy. Household characteristics obtained from the survey include household
size, tenure, structure type, income, and vehicle ownership. This survey is updated every 10
years.
On-Board Transit Survey
The most recent on-board transit survey was completed in the Fall of 1990. Over 40,000
surveys were collected on-board the region's 90 transit routes. The survey was conducted to
determine trip-making characteristics such as purpose, fare used, mode of access to and from
transit stops, and the origin and destination of the trip. In addition, the demographic
characteristics of transit riders were obtained, including age, gender, income, occupational
status, number of vehicles available, household size, geographic area of residence, and
frequency of use of public transit The survey results are used by the region's fixed-route
transit operators in their transit planning activities.
Regional Transit Passenger Counting Program
This program updates passenger boardings and alightings by bus stop on an annual basis.
While the program was initiated in 1979 to satisfy Urban Mass Transit Administration (now
Federal Transit Administration) requirements, it is also designed to provide ridership and
USEPA Office of Water (WH-547). US-Mexico Border G1S Catalog attachment. July 1993.
Page 65
-------
other performance data to the region's fixed-route transit operators. In addition to boardings
and alightings, the number of passenger and revenue miles, average trip lengths, passenger
and revenue minutes, standing and seating capacity, maximum loads, gallons of fuel used,
miles of service over capacity, and on-time performance indicators also are measured for
each route. Transit operators usejhis information to correct running times, determine the
frequency of service, analyze route configurations and bus stop locations, and-to analyze the
need for facility improvements and equipment changes.
Trolley Ridershin Estimation Program
Since the Trolley is a barrier-free-system (no turnstiles, etc.) it is not feasible to count the
number of persons boarding and alighting each vehicle to determine ridership. It is therefore
necessary to estimate ridership by combining information collected from vendomat machines
with survey information collected on-board the vehicles by fare inspectors. The purpose of
the fare inspector surveys is to determine the percentage of passengers using a monthly pass
or other types of fare media not requiring the use of vendomat machines. By combining data
from these two sources (vendomat machines and fare inspector survey data), a monthly
estimate of ridership by fare payment type is produced. Average ridership for weekdays,
Saturdays, and Sundays are calculated for the system and by line. A data base is maintained
that contains trolley ridership information dating back to 1981, when trolley service began.
Average Daily Traffic Volumes
Each jurisdiction annually conducts vehicle counts on local streets and arterials, while
CALTRANS performs vehicle counts on the region's freeways. Each agency makes those
counts available to SANDAG for inclusion on the Average Weekday Traffic Volume map
that is published each year. The 24-hour volumes are standardized to represent traffic
volumes on an average weekday. Also published is a report listing all street segments and
their current and historical volumes over a five year period.
Vehicle Occupancy and Classification Survey
Vehicle occupancy monitoring programs were conducted in the San Diego region in 1981,
1985, and 1990. Each year, field counts at one hundred locations were made on non-holiday
weekdays during the morning peak commute period (6:30 a.m. to 8: a.m.), with counts
recorded at 15-minute intervals. At the same time that occupancy counts were made, field
surveyors determined vehicle classification data (trucks, passenger vehicles, motorcycles,
etc.). The results of the vehicle occupancy monitoring program are used to evaluate facility
needs, mode splits, vehicle emissions, and fuel consumption. The data also provide
Pag* 66

-------
information on occupancy counts over time and indicate whether programs to encourage
higher vehicle occupancy through ridesharing programs prove to be effective.
Freeway Level of Service Analysis
Traffic engineers utilize a level of service (LOS) rating to indicate the degree of congestion
along freeway segments. Although there are various methods to determine these ratings, the
method used locally is based upon the "volume/capacity" concept (the number of vehicles
divided by the freeway segment's capacity). Related to this calculation is vehicle density (the
number of vehicles per mile per lane) and the average travel speed. Using this methodology,
with vehicle counts provided by CALTRANS, six LOS ratings have been defined. Current
and historic weekday LOS information for 61 locations along the region's 11 freeways is
maintained. Hourly LOS data are also available to help evaluate the spreading of peak
period travel time. By monitoring traffic conditions over time, areas with the most critical
levels of congestion can be addressed.
Bicyclg Use Survey
The Regional Bicycle Counting Program identifies directional bicycle volumes at major street
intersections. To conduct the counts, surveyors are stationed at intersections throughout the
region in the morning between 6:00a.m. and 9:00a.m. and in the afternoon between
3:00p.m. and 6:00p.m. Separate counts of adult riders, children, and those on mopeds are
taken. This study is conducted approximately every two yean, with many of the sites
staying the same each year to allow for the analysis of data over time. In 1990, counts were
taken at 71 locations. The information is used by local government agencies in planning for
and providing a regional network of safe bicycle routes and facilities that will encourage
people to use the bicycle as an alternative means of commuting. The next bicycle counts are
scheduled for Fall 1993.

MODELS
Regional Growth Forecasting Models
There are two phases to the forecasting process and four major models used to obtain the end
results. The first phase uses the Demographic and Economic Forecasting Model (DEFM),
which produces a forecast for the San Diego region. DEFM combines a population-
employment forecasting model with an economic impact analysis system. It uses a series of
econometric equations, derived from historical data, which reflect the interaction between
economic forces and population growth. The model produces annual forecasts for the region
which represent the overall demand for housing and jobs over a 25-year forecast period.
DEFM consists of six sectors which are directly or indirectly linked. The sectors are
population, employment, income, construction, prices, and public finance.
The second phase uses two allocation models to distribute the regional forecast to subareas
within the region. The first of the subregional allocation models is the Employment
Allocation Model (EMPAL). It produces the future distribution of employment. This
distribution becomes the input to the second model used in the allocation process, the
Projective Land Use Model (PLUM). PLUM allocates other activities, such as population
and housing units to subareas based upon the location of employment, the capacity to absorb
additional development, and transportation accessibility.
The final model used in the forecasting process in the Sophisticated Allocation Process
(SOAP). SOAP is a micro-allocation model that distributes the subregional level forecast
from PLUM/EMPAL to the smallest geographic component, the Master Geographic
Reference Area (MGRA). The allocation of development activities to MGRAs is determined
by two primary factors-the availability of appropriate land for that activity and the
accessibility to employment opportunities.
Transportation and Transit Models
Transportation modeling efforts utilize the transit and socio-economic data bases and transit
networks described elsewhere in this report, as well as a number of others unique to
transportation planning. The Transportation Planning Package (TRANPLAN) is a set of
computer programs that assist in regional and subregional planning of street, highway, and
transit facilities. TRANPLAN includes a system of trip generation, trip distribution, and
mode-split models which create current and projected person, vehicle, and transit trips based
Pap 68

-------
on existing and future land uses. The models are updated based on information obtained
from the Travel Behavior Survey and On-Board Transit Survey, while existing and future
land use patterns are obtained from the Regional Growth Forecast. TRANPLAN is
commonly used to evaluate the traffic impacts of proposed development and improvements
to the region's existing and future highway and transit systems. The model is also used to
analyze person or transit trip movements between areas.
In addition to each jurisdiction's Circulation Element of the General Plan, SANDAG
maintains two computerized street network systems-a highway modeling network and a
transit modeling network. The networks are used in transportation modeling, facility site
location analysis, and computer map generation.
The highway modeling network consists of all freeways, prime arterials, major arterials, and
some smaller streets for the purpose of connectivity. Included are current street/road
patterns as well as future configurations. Some of the attributes associated with each street
segment are link distances, peak and offpeak travel times, posted speeds, name descriptors,
traffic volumes, functional road classifications, capacity (the amount of traffic which can
effectively flow through a section of roadway), and signal or stop sign controls.
The transit modeling network is a subset of the highway network. All street links with transit
activity are contained in the transit network files. All routes and their possible configurations
are represented. Street links with transit service have a number of attributes associated with
them, including route numbers which use the link, frequency of service or headways, number
of bus stops, travel times, bus speeds, and fare structures. Bus speeds and travel times are
based on a relationship to auto speeds and drive times, number of bus stops, bus stop
activity, and time of day. 1986 and 1990 base year networks are maintained, as well as
future networks for 1995, 2000, and 2010.
A short-range transit model called STOPS is used in evaluating the demographic and
economic characteristics of potential transit riders. It is an interactive menu-driven micro-
computer data retrieval system that includes graphics capabilities. Information such as race,
gender, age, housing value, and employment characteristics can be obtained for the
population within user-specified distances from existing or proposed transit stops.

BOUNDARY FILES AND COVERAGES
As discussed in the Data Bases section of this report, SANDAG maintains an updated version
of the DIME file as the street center-line data base. Also maintained as part of the
geographic information system is a collection of boundary files and coverages for geographic
areas and features such as census tracts, jurisdictional boundaries, special districts, freeways,
local streets, and natural resource areas. These files are used in data analysis, modeling,
reporting and tabulating data, and for graphically portraying data in map form. User-defined
areas, such as service areas, can be digitized (put into computer-readable format) and added
to the collection of boundary files. These files can then be used in a computer overlay
process to tabulate and map data for those areas. The following is a list of the coverages and
boundary files maintained as part of the Regional Information System.

THE CENTER FOR EARTH SYSTEMS ANALYSIS RESEARCH
(CESAR):
AN INTEGRATED GEOGRAPHIC INFORMATION SYSTEMS AND
DIGITAL IMAGE PROCESSING LABORATORY
The Department of Geography at San Diego State University houses the Stephen and
Mary Birch Center for Earth Systems Analysis Research (CESAR). Originally proposed in
the summer of 1986 as a facility emphasizing remote sensing, CESAR instead evolved into a
state-of-the-art, integrated geographic information systems (GIS) and digital image
processing (DIP) laboratory. CESAR serves a dual function as both an instructional facility
and a research laboratory supporting externally funded grants and contracts. Specific courses
at the upper division and graduate levels as well as independent student research occur within
CESAR. Simultaneously, a wide-variety of funded activities are in place. In mid-1991 the
total value of projects in progress was nearly $2 million and included international, national,
state and local-level projects funded by public and private sector institutions.
To provide a context of the academic environment in which CESAR functions, a
thumb-nail sketch of the university and department seems appropriate. San Diego State
University is the flagship campus of the 20-member California State University system. A
comprehensive university with some 33,000 students, SDSU offers bachelor's degrees in 76
areas, the master's degree in 56, and the doctorate in 8, including geography. Several
departments in the university have gained national stature for the quality of their programs.
The faculty attracted nearly $45 million dollars in research awards in 1990-1991. Within the
Department of Geography there aie 20.5 faculty positions to serve some 165 undergraduate
and 50 graduate majors. Approximately 5,000 students per year take classes in Geography.
The department's primary specialties include GIS, cartography, remote sensing/DIP, and
spatial statistics as applied to problems in urban and behavioral geography, biogeography,
environmental geography, and Latin America. The Bachelor of Arts, Master of Arts, and
Doctor of Philosophy (offered jointly with the University of California, Santa Barbara) as
well as a Certificate in GIS are awarded in Geography.
I. CONCEPTUAL STAGE
Prior to 1987 the department's ability to conduct a program of research and
instruction involving digital cartography, GIS, DIP, and remote sensing was severely limited
by inadequate facilities. Although courses in automated cartography and remote sensing had
been offered for more than a decade, the level of technology employed was very low. For
example, as late as 1986, image processing was limited to two or three small software
packages, such as M1CROPIPS, running on a single IBM PC. Automated cartography (AC)
and GIS courses were supported largely with Harvard software (e.g., SYMAP and GRID),
D1SSPLA, basic plot subroutines, and other graphic packages residing on the university's
CYBER mainframe computer. These programs were accessed by telephone lines via 300-
baud modems and displayed on four "dumb" terminals. In-house graphics capabilities
consisted of a Tektronix 4027 CRT, a Hitachi 42-inch digitizer, and a 12-inch Zeta plotter.
All of the equipment was housed in a room of less than 200 square feet The two courses
taught annually in remote sensing and automated cartography enrolled a total of
approximately 20 students. Because no staff support was available for these activities,
technical supervision was provided by the two faculty with expertise in RS/AC and by some
of the graduate students enrolled in the courses.

In a broader context, during the mid-1980s the department was grappling with ways
to develop an identifiable focus which would allow it to move forward. We were seeking
ways to attract and retain outstanding young faculty while also improving our program's
stature, locally within the university as well as nationally within die discipline. At the same
time it was also becoming clear that a revolution was occurring in both software and
hardware, technically as well as cost-wise, that presented exceptional opportunities for
geographic research and instruction. Departments that developed programs which placed
them at the forefront of these changes could have the potential to make enormous strides
quite rapidly. This fortuitous conjunction in a time of departmental soul-searching and
accessible technological innovation was the catalyst which was to lead to the
conceptualization of CESAR.
The combination of RS/DIP/GIS as the technical focus of the department offered a
number of benefits. First, we had a small but highly skilled nucleus of faculty (Richard
Wright and Douglas Stow) already working in these areas. By adding to this core, we felt we
could bring about change without major disruptions in existing activities. Second, the
techniques were applicable to problems in both human and physical geography thus allowing
us to reach a wide range of student and faculty interests. We also perceived that this would
allow us to develop a facility which could broadly benefit the faculty as a whole and act as an
inducement to attract new faculty. Third, we felt strongly that students with a background in
these areas would be much better prepared for spatial problem solving. We concluded that
auricular changes in this direction would be a significant benefit for our majors, both
graduate and undergraduate. Fourth, application of these techniques to spatial problems
could provide significant advancements to geographic knowledge. This complimented the
desire of the faculty to increase their opportunities to do good, basic scientific research.
Fifth, image processing and GIS could be used to develop cross-disciplinary research ties on
campus, an important consideration from both a scientific and political perspective. Sixth,
there are excellent external grant/contract opportunities for faculty working with these
techniques. Because of limitations inherent in the California State University system budget,
it was important for the department to attempt to broaden its base of financial support
Finally, the public relations or "gee whiz" effect of the techniques was very strong and this
could have an important impact upon administrators in control of funding. Virtually all of
the university's higher administration is composed of people trained in the sciences and they
recognized the importance of computers in research and instruction. Along with several
additional positives, we concluded that an initiative to create a major laboratory facility in
RS/G1S should be pursued vigorously.
Gearly, the pre-1987 situation had to be drastically upgraded if the department was to
conduct a major program of RS/GIS instruction and research commensurate with the
expertise and professional aspirations of the concerned faculty. Thus, the Department Chair
(Ernst Griffin) along with Profs. Wright and Stow set about to determine what was needed to
create an adequate laboratory. A number of hardware and software vendors were contacted
for information and a great deal of literature was perused. Several persons who had hands-on
experience with various systems configurations in established labs were contacted far their
opinions and advice. After a possible hardware/software configuration was agreed upon
internally, we invited a consultant (Dr. John Jensen, Department of Geography, University of
South Carolina) to critique our thinking. As a result of his visit a revised plan was
established which gave us significantly greater flexibility and growth potential than our
original design. The cost of bringing in someone intimately familiar with setting up a lab
proved to be veiy worthwhile and cost effective.
Once we felt that we had an adequate idea of what was needed, informal contacts
were made with key administrators on campus to solicit their views and suggestions as to
how to proceed as well as to try to gauge the degree to which they might support our

initiative. Several independent discussions were held with the Dean of the College of Arts
and Letters, the Dean of the Graduate Division and Research, the Vice President and
Associate Vice President for Academic Affairs, and the Executive Director of the SDSU
Foundation. We outlined what we wanted to accomplish, what resources we thought would
be required, and what we envisioned the results would be for the department, the College,
and the university. We emphasized the merits of RS/GIS as an instructional and a research
tool, how our students would benefit if our ideas were implemented, and how the initiative
tied into the long-term planning of the department. In turn, we received encouragement and
viable suggestions on strategies for formulating a proposal. This may have been the key
phase in ultimately having a successful project because it involved key decision-makers early
in the process and may have brought them "on board" psychologically.
IL PROPOSAL STAGE
The initial official proposal to create a center emphasizing remote sensing, the
precursor of CESAR, was made in two parts during the late Spring of 1-986: one through the
university's "Lottery Funds" competition and a second directly to the Vice President for
Academic Affairs. Although the proposals were made separately, they were integrally
related in that the first provided the funding for hardware/software while the second made
position monies available. Additional proposals to suppon CESAR were submitted and
funded in subsequent years from the university and externally.
As a pan of the law creating a state lottery in California, a percentage of the income
generated is divided among the various parts of the educational community. Within the CSU
system, a portion of those monies go directly to the individual campuses and are utilized at
the discretion of the presidents. Because of their sources, these funds are generally to be
used to benefit the instructional mission of the university. Therefore, the department
requested $200,000 to develop a center which focused upon advanced undergraduate and
graduate instruction in image processing of remotely sensed data and its cartographic
analysis through geographic information system technologies. Given the skills of the
existing faculty, the specific foci of the Center were to be hydroclimatology, geomoiphology,
and biogeography with an emphasis upon spatial analysis of form and process. It was argued
that the Center would enhance the learning experience of students in geography and closely
allied disciplines by providing hands-on experience with "sophisticated computer-based
techniques in remote sensing and geographic information systems". The proposal was
funded in the Summer of 1986.
The monies provided were used to purchase the initial hardware and software needed
to equip the lab. Three ERDAS PC turn-key systems with IP and GIS software modules
were the main components acquired for remote sensing activities, along with peripherals
such as an electronic digitizer, a video digitizer, a tape drive, an ink-jet printer, and a QCR
digital video copy camera. Two hand-held radiometers and polycorders were purchased for
field data collection. ARC/INFO software for use on a VAX minicomputer cluster was
acquired as the base for our GIS functions along with two Tektronix graphic terminals. A
CalComp plotter was also purchased to provide hardcopy.
Simultaneously, the Vice President for Academic Affairs was asked to approve and
fund a new entry-level tenure track position that would allow the department to bring in a
second specialist in remote sensing of the physical environment so that we could begin to
create a node of expertise in that area. The individual hired would be expected to become
grant active. To facilitate this latter consideration, a zero-teaching load was to be assigned
for the first semester. The Vice President and the Dean of the College of Arts and Letters
agreed to fund this position for two years, after which the department would absorb the

position costs. Subsequently, Allen Hope was hired to fill this position. As a result, the
Center was funded and three faculty with RS/G1S skills were in place.
One of the reasons that the university supported this initiative was because of the
excellent possibilities for externally funded projects that could be obtained by researchers
using RS&ISjechniques. The department estimated that with qualified faculty the new
Center could generate a steady-state grant/contract funding base of $150,000 per year after
four years. These projections were evaluated by the SDSU Foundation's Development
Office (the university's research auxiliary) and were considered to be reasonable^As a result,
the university's administrators may-have felt that they were making a "goodlnvestmeru"
which could produce tangible returns.
Overall, we faced very few hurdles in pursuing this initiative. The university's
administrators at various levels were very supportive of our ideas and worked to help them
succeed. We are convinced that this was due to the fact that we had done a great deal of
groundwork all along the line. As a result, we were able to anticipate questions, provide
pertinent information in a timely manner, and intelligently project the impact of the program.
Further, the department had a Five-Year Plan in place and the proposal fell within the
objectives defined within the plan. -The lesson from our experience is clear homework is
good.
IIL ACQUISITION STAGE
Since its inception in 1986 there have been three major purchases of hardware and
software for CESAR (See Table 1). Two of these were the result of successful lottery
proposals within the university and the third was self-funded through a loan from the SDSU
Foundation. These three main acquisition phases will be discussed here. In addition, we
have an on-going program of purchases to maintain and up-grade CESAR's equipment base
financed through monies generated by CESAR.
Hardware and Software Acquisition • Phase 1
During the first year of funding the equipment and software actually purchased varied
little from that which was proposed. The only additions were the numerous odds and ends,
such as cables, computer chips, connectors, and supplies, that are essential to the operation of
a computer facility. Individually, these items do not cost much, but in total they added
several thousand dollars to the expenditure. That the initial purchase plan survived largely
intact into the acquisition stage was due in large part to the detailed planning that was done
and the short time (approximately three months) between proposal submission and systems
purchase.
An important aspect of the proposal stage that expedited the acquisition process was
the evaluation of hardware and software. Prior to submitting our proposal, it had been
determined that ARC/INFO and ERDAS software would comprise the primary GIS and DIP
capability of the new facility. These two packages and the companies that produce them
— ESRI and ERDAS - rated highest in terms of the factors that we considered to be
important when selecting software and hardware for a research/educational facility.
Additionally, both companies recognized the potential value of having their software
installed at San Diego State University. Thus they were very cooperative in helping us to
define our needs as well as potential solutions. Consequently, when the proposed purchases
went out for bid ESRI and ERDAS were the only vendors that could provide
software/hardware with the capability we needed at a price we could afford.

Hardware and Software Acquisitions - Phase 2
As mentioned previously, while the initial proposal emphasized remote sensing,
within a year of its funding CESAR had evolved into an integrated GIS/RS research and
instruction facility. In the summer of 1987 a second lottery grant, this one for $93,000, was
funded by the university to upgrade .CESAR to accommodate more students, larger databases
'and more sophisticated modeling. These monies were used to purchase Macintosh lis, 386
PCs, and additional ARC/INFO and ERDAS capability. In addition, at roughly this same
time the university provided. CESAR with a VAX 750 mainframe minicomputer for
ARC/INFO. While somewhat da&d, having a VAX in-house within CESARTpermitied us to
process much larger data sets as well as utilizing "Live-Link" techniques between ERDAS
and ARC/INFO. The original VAX 750 was recently replaced with a VAX 780. The
university maintains the CESAR VAX and we continue to have full access to all systems in
the University Computer Center through an Ethernet link.
The evolution of the facility as an integrated GIS/RS center was hastened by two
major grants. Within months after the estaBlishment of CESAR a contract was awarded to
Richard Wright by United Enterprises Inc. to develop a land use GIS for a 9,000-acre portion
of Otay Ranch in southwestern San Diego County. The primary purpose of this 15-layer
database was to demonstrate how GIS technology could be employed in planning and
managing the development of the Otay Ranch subdivision. The owners of United
Enterprises who are also directors of the Stephen and Mary Birch Foundation, were pleased
with the outcome of the Otay Ranch GIS pilot project. As a result of this project a formal
proposal was submitted by Richard Wright and Ernst Griffin to the Stephen and Mary Birch
Foundation to support the creation of a center for excellence in environmental and land use
analysis using GIS and IP technologies. The request, which was funded in September of
1988 in the amount of $632,000 over a five-year period, has several components: an
endowed chair contribution, graduate research assistant support, database development for
research and instruction, faculty released time for research and curriculum development,
hardware and software purchases, and community outreach via a series of summer
workshops. This grant was very important to the early development of CESAR in part
because it provided a degree of financial stability for several years.
A second grant that has had a major impact on the early evolution of CESAR was a
National Aeronautics and Space Administration award to Douglas Stow in the amount of
$600,000 over three years for a project entitled ^Efficient Updates of Vector-Coded
Geographic Information Systems Using Remotely Sensed Data". This on-going
collaborative effort with ERDAS, ESRI and the San Diego Association of Governments
(SANDAG) involves research to promote the commercial use of satellite image data and
image processing systems for updating land use coverages in regional GISs. Techniques
have been developed and tested far integrating raster image data with vector GIS coverages.
The techniques have been transferred to SANDAG and are now being used operationally to
update a 1986 land use inventory to 1990 conditions. Similar techniques are now being
employed in another CESAR project for mapping vegetation and identifying sensitive
habitats in southern California. This grant, with its emphasis on raster-vector integration, has
helped to focus research and instructional activities in CESAR.
Like all grants and contracts accepted by CESAR, these projects incorporate graduate
students and often advanced undergraduates in the research process. These students receive
practical training in a wide array of research activities which enhance their educational
experience. A large percentage of our graduate students' theses and seniors' honors projects
emerge from their involvement in sponsored research projects. At the same time, the
specialized techniques and databases which result from research activities are frequently

integrated into courses taught in the department. Thus there is a clear and symbiotic
relationship between the instructional and research goals of CESAR.
Hardware and Software Acquisitions - Phase 3
In recognition of the importance of conriiiQing to upgrade CESAR's computing
capability, the department recently completed the third phase of hardware and software
acquisition. Since- its inception, teaching and research activities have been conducted
simultaneously within CESAR. As the volume of grants/contract activity has expanded, so
has the number of our faculty Who are skilled in IP/GIS and spatial techniques. From the
original nucleus of two colleagues Teaching two courses per year, we now haveseven faculty
members teaching more than a dozen courses per year in which IP/CIS are incorporated into
the curriculum. This parallel growth of instructional and research activities has placed a
good deal of stress on CESAR facilities. Therefore, we decided to separate some of the
instructional functions from the research activities in CESAR in order to enhance the
efficiency of both areas.
To accomplish this goal additional equipment was needed and a $96,000 purchase of
486 PCs, MAC IlCis, and SUN equipment was made. The funds were provided through a
loan from the University Foundation which will be repaid within 18 months from fees
charged to funded projects using CESAR.
Physical Plant
Concurrent with the receipt of new hardware and software in early 1987, 600 square
feet of floor space was dedicated to CESAR by converting the depanment's remote
sensing/aerial photograph interpretation laboratory into a GIS/DIP facility, which roughly
tripled the area previously available. The remote sensing/aerial photography interpretation
lab was temporarily relocated across the hallway into a portion of die cartography laboratory.
The space dedicated to CESAR was doubled the next year by expanding into an
adjacent room, which was obtained in a trade with the Sociology Department The existing
cartography laboratory (1250 square feet) was split into two rooms, one of which was given
to Sociology in exchange for the room adjacent to CESAR. The other room, of about 650
square feet, continued to be dedicated to manual cartography, remote sensing, and map and
aerial photograph interpretation. Finally, the space devoted to CESAR was increased to
3,000 square feet in December of 1990 when new research and office space, built especially
for the Department of Geography, was occupied.
IV. OPERATIONAL STAGE
General Layout
As the room layout shows (See Figure 1), CESAR facilities consist of three main
rooms containing computer equipment The two large rooms on the west, separated by a
CPU room and offices for the Technical Manager and other CESAR staff, are devoted
primarily to research activities in GIS/DIP but also accommodate specialized graduate and
advanced undergraduate courses and independent student research. The adjoining large
room on the east, the Spatial Analysis Laboratory (SAL), is used mainly as an instructional
laboratory for upper division and graduate courses in GIS, RS, spatial statistics and
automated cartography. A darkroom and an office for the Department Cartographer round
out these new laboratory facilities.

. The three large rooms used in CESAR are well designed for their intended uses. A
30" x 48" computer table for each piece of equipment, a set of four 30" x 72" tables for
workspace and small group discussion, map storage cabinets, supplies storage cabinets,
bookcases for manuals, light tables, numerous bulletin boards, white boards, adjustable
chairs and a projection screen comprise the furnishings for the three large rooms. The
importance of numerous bulletin boards and white boards for posting work and equipment
reservations schedules, working illustrations, messages, and informative maps and charts
cannot be overemphasized. Likewise, it is important to provide adequate wall space and
bookcases for the very large volume of reference manuals typically needed to support use of
the equipment and the software.
Hardware
The department has put together an impressive facility in terms of hardware
capability (See Table 2). On the west side of CESAR, the computer hardware consists of
clusters of the following equipment: 1) Tektronix graphics terminals, 2) 486 PCs and 3)
workstations (SUN SPARC and IBM RISC). The adjoining spatial- analysis laboratory
contains eight 386 PCs and eight Macintosh computers (4 Mac lis and 4 Mac IlCis),
eventually to be expanded to 20 student stations. All hardware and software in the Center is
internally and externally linked via the Ethernet (See Figure 2). These linkages include
connections to the in-house VAX 11/780 as well as to the university's VAX 6000-320.
CESAR has been outfitted with several different digitizers and many different types
of printers and plotters (See Table 2). All are available to students for meeting the
requirements of both laboratory exercises and research. The equipment is available first on a
reservation system then on a first-come-first-served basis. Providing adequate hardcopy
capability at a low to moderate cost has been and continues to be a difficult problem. The
Calcomp pen plotter, the Tektronix thermal printer, and the LaserWriter are the most popular
devices for output, but are inadequate for large-size color output requiring extensive polygon
fill. Other hardcopy technologies, e.g. electrostatic printers, are being considered, but high
purchase and maintenance costs militate against them.
In planning the acquisition of computer hardware, we decided that it would be
preferable to install small numbers (4-8) of several different types of equipment rather than
large numbers (20 or more) of one or two types. The advantage of this approach is that it
maximizes the flexibility and adaptability of the facility for responding to technological
change and different research/instructional needs. A negative aspect of this approach is that
fewer students can be served Having a wide variety of computer hardware, with different
operating systems, also presents more complex maintenance and management problems.
Software
CESAR's software holdings for GIS, DIP, automated cartography, and spatial
statistics are extensive (See Table 3). Heading the list of software are ARC/INFO and
ERDAS. The former is available on PCs, workstations, and the two VAXs, whereas the
latter is installed on PCs and SUN workstations. As mentioned previously, ARC/INFO and
ERDAS are integrated on some stations via the "live link". ARC/INFO gives the department
vector GIS capabilities while raster functionalities are provided by ERDAS, SPANS, OSU-
MAP, IDRISI, and the MAP II Map Processor. ARC/INFO, SPANS, and ERDAS are
employed for both research and instruction. OSU-MAP, IDRISI, and MAPII are used
primarily for instructional purposes.

Security
The security measures for CESAR's hardware and software are moderate at best
Systematic backup of data is not done but there are a number of protections for software. For
example, all system software is backed up, account passwords are changed frequendy, many
data sets are available for read access only, and archival data is on tape in a locked room with
limited access privileges. There is no special security for the equipment excepffor that
provided by locked doors, the presence of CESAR staff and research assistants, and nightly
checks by campus police personnel. CESAR's vulnerability to vandalism ancLtheft, while
relatively high, has yet to be a problem in the five years of its operation.
Laboratory Use
CESAR is a department facility. As such, instruction and research use is largely
confined to geography faculty and to students enrolled in geography courses (See Table 4).
The SAL portion of CESAR is a combined lecture/laboratory facility. It is used
primarily for those junior-level GIS (and related) classes whose hardware and software needs
can be met with Macintosh and PC equipment The lectures for senior/graduate-level
students(500-numbered courses) are also conducted in SAL, but their laboratories must be
conducted in CESAR to take advantage of CESAR's more sophisticated GIS technology. In
the graduate portion (600- and 700-numbers) of the curriculum, classes are taught in the
seminar room, with CESAR being used for canying out class-related GIS research activities.
Approximately 50 percent of the courses listed in Table 4 are offered each semester,
and have a combined enrollment of approximately 115. Another 25 students and faculty
normally work in CESAR on various research projects, making for a total of 140 users who
must be accommodated each semester. To serve this volume of research and instruction,
priorities have to be set for the use of most equipment. Students in a particular class have
priority status for using equipment during the laboratory portion of their class. At other
times students can sign up for two-hour blocks and can continue working even longer at a
station until they are bumped by another person. This system maximizes access to the
equipment and works fairly well except near the semester's end where there is a large
demand by students who have waited until the last minute to complete class projects.
Most GIS courses involve two hours of lecture and three hours of laboratory per
week. A typical laboratory session consists of 1/2 hour of demonstration followed by 2 1/2
hours of work on an exercise or project under the immediate supervision of an experienced
graduate student assistant The average student will spend an additional 4-5 hours of
laboratory time each week outside of class, for a total of 7-8 hours of laboratory time per
week.
Because it is largely a self-supported facility, principal investigators on funded
projects who wish to use CESAR in their research are asked to include a CESAR use-charge
within their budget proposals. Monies generated in this way are used for maintenance and
up-grading activities within CESAR.
Operation of CESAR
During the academic year (September-June), CESAR is open from 8:00 AM to 10:00
PM, Monday through Friday, and from 9:00 AM to 5:00 PM on Saturdays and Sundays.
Summer hours are fnom 8:00 AM to 5:00 PM on weekdays. The only time that CESAR is
unavailable for use is on Fridays from 3:00 to 5:00 PM when clean up and preventative
maintenance are conducted. After 5:00 pm, Monday through Friday and on weekends, the
Center is supervised by graduate assistants who are also working on CESAR research

projects. All graduate research assistants involved in CESAR projects are issued keys to the
facility and can enter it at any time. Undergraduates can obtain access to CESAR after hours
by checking out a key for 24 to 48 hours from the Geography Department Office. CESAR is
available primarily to students enrolled in courses in the Department of Geography, typically
G1S/RS and related classes, and Geography faculty and graduate students working on
research projects. Use by faculty and students outside the department is limited to those who
are involved in joint research with members of the Geography faculty.
Responsibilities
The organization of CESAR reflects several aspects of its evolution and therefore
responsibilities for the facility are shared. As a departmental facility, the Department Chair
is integrally involved in its overall management As a cooperative instruction and research
laboratory, faculty are intimately involved in establishing policies and procedures as well as
day-to-day operational oversight. The daily operation of the facility is in the hands of
CESAR's Technical Manager. These relationships and their interactions are outlined here.
Department Chair The Department Chair (Ernst Griffin) is the general manager for
CESAR with ultimate responsibility for its functioning (Figure 3). He works closely with the
Faculty Executive Committee to establish policies and with the Technical Manager to see
that those policies are carried out He interacts with upper level administrators in the
University Computer Center, the Office of the Vice President for Academic Affairs, the
College of Arts and Letters, and the SDSU Foundation on matters that may affect the well
being of CESAR. He is also responsible for public relations with these groups.
Executive Committee The Executive Committee is comprised of five geography
faculty (Janet Franklin, Allen Hope, Gerard Rushton, Douglas Stow, and Richard Wright)
with expertise in DIP, RS, and GIS as well as various application areas such as hydrology,
biogeography, and decision support systems. They direct or co-direct approximately 90
percent of the funded research conducted in CESAR. As mentioned above, committee
members work closely with the Department Chair on policy matters. They also provide
advice to the Technical Manager on CESAR's daily operations and its technical needs. As
principal investigators on projects, they give direction to graduate research assistants and
other students who are working on CESAR projects. In addition to the Executive
Committee, meetings involving all CESAR faculty users (euphemistically called Ccsarians)
are held periodically to discuss topics of importance. The entire faculty of the department is
also briefed regularly as to the status of CESAR and any changes in policies which may have
been made.
Technical Manager The Technical Manager (David McKinsey) is responsible for
the day-to-day operations of CESAR. He reports to the Department Chair and the Executive
Committee and interacts with personnel from the University Computer Center, Geography
faculty, the clerical staff, research assistants, and students enrolled in GIS, remote sensing,
spatial statistics, and various classes using GIS/DIP applications. The Technical Manager
assists faculty and students in the use of GIS/DIP systems, orders supplies, schedules and
records equipment use, gives software demonstrations, performs systems and applications
programming, and maintains hardware, software, and the reference manual library. Clearly,
the Technical Manager is a key figure in the successful operation of CESAR.
Clerical Assistant One-half of a clerical assistant's position is funded through
CESAR activities. The Clerical Assistant maintains financial records on CESAR grants and
contracts, prepares purchase orders for supplies and equipment, types project reports, grant
and contract proposals, research papers, and CESAR correspondence. This person is

supervised by the Chair, but interacts directly with the Technical Manager, Pis, and members
of the Executive Committee.
Graduate Research Assistants. Approximately 20 one-half time graduate research
assistants are employed in CESAR through the department. Most of these RAs are supported
by the grants or contracts on which they are working. In addition to project work, research
assistants are assigned evening and weekend blocks of time supervising the use of CESAR.
This allows CESAR to remain open for research and instructional activities even when the
Technical Manager is not on duty. Research assistants repon directly to their faculty
supervisors, but interact frequently with the Technical Manager. On matters relating to
payroll and such things as office space, research assistants interact with the Chair or the
Department Secretary.
University Computer Center (UCC) Personnel The UCC provides a variety of
hardware and software support for CESAR. UCC personnel maintain ARC/INFO software
on the central VAX 6000-320 computer and assist the Technical Manager in the operation
and maintenance of CESAR's VAX 11/780 computer and its GIS software. UCC also offers
an equipment repair service for CESAR's Macintosh and IBM PC computers as well as
picking-up the cost for a number of software maintenance contracts in support of CESAR.
Software and hardware support involves direct communication between the Technical
Manager and UCC personnel. Policy matters require direct communication between the
Chair and UCC management.
San Diego State University Foundation The Foundation is a non-profit auxiliary of
the university. It is responsible for administering all university grants and contracts,
including accounting, purchasing, and payroll functions. The Department Chair and the
project directors interact with Foundation personnel on a frequent basis. Each PI is assigned
a Foundation Project Administrator to coordinate their grant/contract Pis and Foundation
PAs work closely to ensure the smooth administrative operation of projects.
Internal Relationships
It can be concluded from what has been discussed to this point that CESAR is a fairly
complex operation. Internally, within the department, a variety of relationships exist which
must function in harmony if CESAR is to be successful.
Faculty Involvement CESAR has a core of five specialists in GIS and remote
sensing whose professional activities require a well equipped and smoothly functioning
facility' as well as several additional faculty who utilize GIS within their research and
teaching activities. The synergism generated by the interaction of several faculty with vested
interests in the Center has provided the energy and dedication needed for a successful
operation.
Much of the research conducted in CESAR is of interest to more than one faculty
member. The result is that many projects are co-directed by two or more faculty. This has
contributed to a high level of cooperation among the CESAR faculty. Several of the projects
involve vegetation mapping. To facilitate communication, a vegetation specialty group
involving approximately IS faculty and students was established which meets bimonthly to
share ideas, to discuss possible solutions to research problems, and to chart future research
directions. Also, a growing interest in modeling within GIS among faculty using CESAR is
providing a catalyst for interaction across the traditional physical/human boundaries of the
discipline.

Graduate Research Assistants Graduate research assistants play an important role
within the structure of CESAR. They are involved in virtually all phases of grant/contract
research and also lend their expertise to other students using the facility. Research assistants
for CESAR are selected from the pool of applicants admitted to the department's graduate
program and ranked for support by the faculty as 1 whole. From this ranked list, CESAR
project directors are given first choice from among the new, in-coming students with
appropriate technical skills. After consultation with project directors, those chosen for
CESAR assignments are integrated into, various projects on the basis of their skills and
interests. Because the primary selection criteria for departmental research, assistants are
academic performance (GPAs and GRE scores), in some instances there are imperfect
matches between die technical attributes of those selected for RA support and the technical
needs required for specific projects. This is an occasional problem, but one that must be
tolerated within limits because of our desire for CESAR to be integrated with the department.
These mismatches can usually be-remedied within a short time by training RAs in the
specific areas the^may be lacking.
Graduate student labor is an essential component of the CESAR operation. Because
we have had a stand-alone Master's program (undl approval of the joint Ph.D. program with
UC Santa Barbara in the Fall of 1990), students normally leave the program after two years
and thus it is necessary to train new project team members on a frequent basis. The
inefficiencies associated with this turn-over are unavoidable given the desirability of
graduating Master's students in a timely manner. However, this problem should be
somewhat diminished by the growth of the Ph.D. program and the longer tenure of doctoral
students.
Another difficulty in relying upon graduate student researchers is that at certain
points in the semester control over the timing of work schedules is limited because they have
other responsibilities as students. At times, their commitments to courses may detract from
the attention they pay to the assistantship assignments. Thus, in the short term there may be
some interruptions in the flow of project work, causing temporary delays in meeting project
deadlines.
Nonetheless, despite these limitations graduate research assistants have done an
excellent job for us. As a group they have been quick to acquire new skills, very responsible
in fulfilling their obligations, eager to accept responsibility, and often add useful insight to
the projects in which they are involved.
Integration of Research and Instruction Research and instruction are often well
integrated in courses at the both graduate and undergraduate levels, especially GIS classes.
This allows students to leam by participating in "real world" projects while at the same time
the projects benefit through the availability of students to perform fundamental tasks, such as
map compilation, database development, data processing, and data output, required in the
research.
Technical Manger CESAR's technical manager is highly competent, but at times is
overwhelmed by responsibilities that range from supervising the operation of die Center to
assisting students ana faculty in the use of the equipment In terms of die operation of die
Center, this means that delays sometimes occur in accomplishing certain tasks required for
the smooth functioning of the Center and for improving its capability. Also, because the
facility has evolved so rapidly, there has been little opportunity to document all procedures
and inform anon applicable to CESAR. Much of CESAR's operating and project information
is stored only in the Technical Manager's head! The loss of our Technical Manager would
cause a major disruption in the functioning of CESAR. To sustain his morale and sanity, the
Technical Manager has been encouraged to participate in professional meetings and

-------
Page 140
workshops and given opportunities to work in research projects leading to papers at
professional meetings and journal publications. In addition, a half-time technical assistant
has recently been added to alleviate some of the work-load of the Technical Manager.
External Relationships
The success of CESAR depends on its relations to a number of other entities both on
campus and off. As fhe activities of the Center have grown, these considerations have taken
on added importance and consumegreater amounts of time and effort
Department of Geography CESAR is well integrated with other functions in the
department, a situation which contributes to positive attitudes about the Center. For
example, all personnel practices, including the hiring of graduate assistants and technical
staff, are accomplished within the context of. the department's policies on governance.
Discussions of the Center are included in department meeting agenda and are intended to
familiarize all faculty with potential uses of GIS/DIP in their specialties and to clarify the
role of the Center in carrying out the department's mission. The integration of CESAR in the
department has been aided by involving faculty who ait not skilled in GIS/DIP in joint
research that incorporates their systematic training and requires the use of CESAR facilities.
As a result, 13 of the department's 20 tenure track faculty use CESAR either directly or
indirectly.
On Campus On the SDSU campus, administrators in the College of Arts and
Letters, the Vice Resident for Academic Affairs, and the Foundation are supportive of the
department and its GIS/RS programs. This has been translated into improved physical
facilities and significant funding for hardware and software. Relationships with other
departments have been limited to cooperative research situations. To date, joint projects
involving GIS/DIP have been conducted with faculty in civil engineering (hydrology and
transportation analysis), ecology, biology, and geology as well as the Systems Ecology
Research Group. Although specific plans for expanding cooperative GIS/DIP projects with
other departments have not teen formulated, it is anticipated that additional joint research
will be initiated with specialists in computer science, urban planning, and some of the social
sciences within the near future.
Government and Industry Many members of the Department of Geography,
including those on CESAR's Executive Committee, have developed strong links with
community agencies and private industry. Extensive community service and the many
demonstrations of CESAR's capability performed for groups visiting CESAR have raised its
visibility. CESAR's mission includes a significant service component This is accomplished
through training workshops and contract research for public agencies and private firms. A
good example of a beneficial type of cooperative relationship with private industry is seen in
the designation of CESAR as a Beta site for numerous software manufacturers with whom
the Center has been involved.
Other Universities CESAR's relationships extend beyond the Campus boundaries to
other universities. The department is an associated institution of the NCGIA and several of
our faculty have been involved with the GIS Core Curriculum and some of the GIS research
initiatives. The high esteem in which the department's GIS/RS program is held by peers at
various institutions has facilitated the recruitment of excellent graduate students to the
department and their integration into CESAR projects.

V. EVALUATION STAGE
After four years of operation, we are now in a position to evaluate some of the
successes and difficulties associated with the evolution of CESAR. The establishment of a
firm set of goals and planning for the long-term future of the Center within the broader
context of the department's goals is a critical consideration.
Achievement of Goals
Over time, the mission of CESAR has evolved to provide technical support for a
variety of the department's programs. These include supporting upper division/graduate
instruction and research in the areas of geographic information systems, remote sensing,
automated caxtojpaphy, digital image processing, and spatial statistics. The center also seeks
to back research in a variety of geographic application areas such as urban and transportation
modeling and environmental analysis. Finally, CESAR has a community outreach mission
that involves training in CIS, DIP, and RS fen* potential users of these technologies in private
industry and government agencies.
To cany out its missions, a number of goals have been established for CESAR.
These include:
1.	Enriching our students' educational experience by providing laboratory equipment
and hands-on experience for students in GIS, RS. AC, spatial statistics, and
selected systematic geography courses that require technical support
2.	Providing financial support for graduate students in order to attract more and
better students to the graduate program. We have created a large cadre of
graduate students who have a sense of direct involvement in the department
3.	Providing technical support for graduate student thesis research. Without CESAR
or a comparable facility many theses completed each year would not be feasible.
4.	Generating funds to be used to maintain state-of-the-art technology in areas of
rapid change. Without a dependable source of income for upgrading hardware
and software capability, a GIS/DIP facility can quickly become obsolete and
uncompetitive in terms of research grants, and inadequate for instructional
purposes.
5.	Helping to support other department functions that relate to CESAR (i.e. some
purchases made with CESAR funds also are used in support of other courses).
For example, map and aerial photographs obtained for grants or contracts can be
used in support of laboratory exercises on map and aerial photograph
interpretation.
6.	Contributing to the professional development of faculty and facilitating scientific
research which increases the capability of GIS/DIP in spatial problem solving.
The hardware and software in CESAR make it possible far faculty with
specialties in GIS and RS to compete for research grants and contracts to carry
out their research plans.
7.	To provide GIS/DIP/RS training to educators, urban and regional planners, land
developers, environmental consultants, and other members of the community.
This is accomplished through demonstrations and workshops of varying lengths.
USEPA Office of Water (WH-547). US-Mexico Border GIS Catalog attachment July 1893.

Page 142
.8. To develop GISs for public agencies for use in environmental resource
management and urban and regional planning.
In our opinion, many of these goals have been, achieved since the advent of CESAR.
We are proud that in less than five years CESAR has become one of the premier GIS/DIP
university instructional/research facilities in the United States.
Future Plans
- In the next five years it is unlikely that CESAR will experience the same dramatic
increases in floor space and hardware as it has in the past five years. Instead, attention will
focus on upgrading and making more efficient use of existing facilities and on replacing
outmoded hardware and software with new capabilities as they evolve. We anticipate that
several initiatives are likely:
1.	The effort now underway to integrate the various platfoims via the Ethernet
system will be completed in the near future. Additional Ethernet cards, cabling,
and software are required to accomplish this task.
2.	In addition to networking existing equipment, the capability of CESAR can be
enhanced significantly by upgrading some of the existing equipment For
example, the hard disk capabilities of die Sun and Rise workstations are being
expanded. The performances of the ERDAS and PC ARC/INFO 386 computers
are also being increased by installing additional memory. Other improvements
are being achieved by adding 3-1/2" drives to some 386 computers and by
installing DBASE 3 to run with PC ARC/INFO.
3.	As noted earlier, the lack of inter-project communication was identified as an
shortcoming in the functioning of CESAR. To rectify this, a loose matrix
organizational structure consisting of a) vegetation mapping, b) GIS, c)
biophysical remote sensing, and d) image processing/change detection interests
groups has been created to cut across project boundaries. Regular meetings of the
vegetation group for interested faculty and students is producing a cross
fertilization of ideas among projects.
4.	A high priority is being given to obtaining software for analyzing socioeconomic,
demographic, and transportation data. This should encourage more involvement
in the Center by the department's human geography specialists.
5.	Demonstration modules are important for showing the Center's accomplishments
and capabilities. The modules on hand need to be upgraded and new ones need to
be added to the Center's library.
6.	Additional hardware, including tape backup systems, scanning, optical compact
disk, global positioning system, and color projection technologies are being
considered. There is also a need to expand the Center's color graphics and
workstation capabilities and to replace the in-house VAX 11/780 computer with a
more powerful machine.
7.	Some software packages on hand have yet to be integrated into our GIS
curriculum. For example, GeoSQL, SPANS, and GRASS are significant
packages that are just now receiving our attention.

8.	The initial 1.00 permanent Technical Manager position will be increased to 2.00
positions. This additional position will give some relief to the Technical Manager
and bring more knowledge of systems programming and UNIX operating
environments to the Center. This wUl allow a fuller utilization of workstations for
GIS/RS applications.
9.	Although used intensively, die Center soil has some unused research capacity.
More attendon is being given to ways of integrating spatial modeling and decision
support systems methods with GIS/DIP techniques. It is also desirable to expand
the graduate instruction and research uses of the facility in human geography
applications such as urban, socioeconomic, and transportation.
10.	The use of the facility for regularly scheduled upper division/graduate instruction
in GIS/RS is nearing saturation, but there are unused weekend and summer hours
that could be made available for training workshops focusing on specific
applications, analytical techniques, and software packages. Workshops provide
an important community outreach function and can help to increase the financial
base of the Center. However, the community outreach function will continue to
be secondary to the primary mission of research and upper division/graduate
student instruction.
VI. RECOMMENDATIONS
Based on our experience in developing CESAR, we can offer a number of
recommendations for those wishing to establish a similar facility.
1.	A clear statement of the mission and goals of the facility should be articulated
early on. This will determine the facility's operating characteristics as well as the
type of hardware and software to be purchased. For example, a facility that
serves both research and instructional needs will have a different technological
mix than one that is intended for instruction only.
2.	Establishing and operating a GIS facility is a dynamic process that requires
flexibility as well as foresight on the part of those involved. To be successful you
must be able to adapt quickly to changes in technology, personnel, and research
demands.
3.	The Department Chair must be a strong advocate of the facility to the university
administration.
4.	The department and the university administration must be strongly committed to
the creation of a successful facility. Don't be reticent about getting commitments
in writing.
5.	Two or more faculty members with expertise in GIS/DIP and its applications are
needed to mount a successful program and must be able to interact on a frequent
basis. Even more than the administration, they must be strongly dedicated to
making the facility a success.
6.	A permanent staff position and a minimum operating budget should be allocated
to the facility to assure operating stability.

.7. The initial allocations of space and binding for hardware and software should be
sufficient to create substantial capability at the outset of operation. A minimum
configuration is likely to hamstring the effort from the beginning. At least one
workstation should be provided for every three students. Fewer workstations will
not allow adequate student access to GIS equipment during the laboratory session.
8.	Project activities should be initiated as soon as possible to place participants on a
steep learning curve, to establish a track record, and to have a product that can be
demonstrated to administrators, other faculty, and prospective funding agencies.
It is important that a cadre of expert users (faculty, staff, and students) be
established early on.
9.	Devote as much time as possible to demonstrations and other activities which
raise the visibility of the facility to individuals both on and off campus.
10.	Before the facility is established, agreements should be reached regarding
responsibilities for hardware and software maintenance .costs. A clear
understanding of who is responsible for what will help to avoid conflict later on.
11.	Some effort should be made to negotiate cost reductions with vendors on the
purchases of hardware and software, especially on annual software maintenance
costs. However, remember that you normally can't get something for nothing
from the private sector. You must be prepared to offer something of benefit to the
company in exchange for cost reductions, such as the development of applications
software and laboratory exercises.
12.	GIS instruction requires a rich instnictor/student ratio. A minimum of one
instructor or instructional assistant for every ten students is desirable for
introductory GIS classes. Advanced classes involving extensive research projects
may require even fewer students per instructor
13.	Finally, consult early and widely with those who have established successful GIS
facilities. A few thousands of dollars spent on experienced consultants is a wise
investment for an undertaking that can eventually exceed several hundreds of
thousands of dollars!

fers a number of advantages and oppor-
tunities for students, faculty, and funding
organizations. Learning by doing is an ef-
fective educational approach. Additionally,
working on a reai-world project helps gen-
erate interest in GIS and motivates student
learning. Qualified students can obtain
financial support through funded research
projects and gain insights into GIS as a pro-
fession through hands-on experience.
Funded projects are a source of monies for
maintaining a high technological level m
the GIS laboratory. Certainly, experience
on funded projects can augment a faculty
member's knowledge of GIS and thus in-
crease the quality of the instruction offered
to students. Finally, funding organizations
gain access to costly technology and to a
skilled faculty-student labor pool.
The Geography Department at San
Diegc State University has developed a
GIS applications course that is coordi-
nated with funded projects. This article
describes the institutional setting, the
laboratory facilities, and the curriculum
context for the course.

CESAR is welt equipped with CIS hard-
ware and software. The two research-ori-
ented rooms combine clusters of graphics
terminals (Tekironics. Wilsonville. Ore-
gon). 486 PCs. and workstations from
IBM (Armonk. New York) and Sun Mi-
crosystems (Mountain View. California).
The adjoining spatial analysis laboratory is
equipped with 386 PCs. and Macll and
Macllci computers (Apple Computer. Cu-
pertino. California). All hardware and soft-
ware in the center are linked via the
Ethernet network. Linkages include connec-
tions to the in-house VAX 11 /780 minicom-
puter and to the university's VAX 6000-
320 minicomputer (Digital Equipment Cor-

CURRICULUM CONTEXT
Interfacing GIS education with funded
research must be accomplished within a
curncular framework. At SDSU the GIS
curriculum consists mainly of three-unit,
lecture-laboratory courses offered at the up-
per division and graduate levels on a semes-
ter basis. Enrollments in GIS classes are
80-100 students each year. Prerequisites
for GIS classes include one or more
courses from cartography and computer pro-
gramming. Table 1 lists GIS courses cur-
rently offered at the various levels.

Grades are awarded on the basis of student
performance on an essay examination (50
percent), an individual modeling activity in-
volving an oral presentation and a written
report (20 percent), and a team project that
also includes an sal presentation and a writ-

the course comprises 30 one-hour sessions
devoted to lectures on GIS applications
topics, an essay examination, team oral re*

eling projects. The modeling project con-
ducted by each student is based on the data
base that is prepared as a part of the team
project, as described later in this article.
The course lectures represent a combina-
tion of applications-oriented topics and a re-
view of ARC/INFO software on the VAX
minicomputer, the SUN workstations, and
the PCs.

for die laboratory is to allow students to ap-
ply the GIS implementation concepts cov-
ered in the lectures. This is accomplished
using a combination of demonstrations, dis-
cussions. tutorials, and work on current
projects Data base compilation data base
automation, analysis and modeling, and
hard-copy generation are among the topics
covered. ARC/INFO software is employed
for mosi projects, bul other packages are
used as the need dictates. Student not al-
ready familiar with the software are re-
quired to spend approximately 40 hours in
the first two weeks working through soft-
ware training materials.

projects are the activities (hat focus the stu-
dents' GIS education At the third class
meeting (he 18-20 students are assigned to
four teams of 4 to 5 students each Prior to
creating the teams, students are surveyed
to determine their knowledge of GIS and re-
lated disciplines, their professional inter-
ests, and their academic abilities. Assign-
ments result in teams that are roughly
equal on the basis of student strengths and
weaknesses Each team is assigned to a cur-
rent funded project under the immediate su-
pervision of a graduate research assistant
(GRA) who is already working on the
project The GRA meets with the team on
a regular basis and provides guidance in all
phases of data base development and mod-
eling. and. in general, serves as a resource
person for students on all matters relating
to the project.
Once teams are formed, each is briefed
about the project by the assigned GRA
The briefing comprises information about
(he project's background, its objectives, cur-
rent status, and a description of the layers
tn the data base that Hill need to be cre-
ated. Additional familiarity with the proj-
ect is provided through a meeting between
the students and their project's client Stu-
dents also take a reconnaissance Held trip
to the project site if it is located within 50
miles of the university. The visit allows stu-
dents to better visualize the relationships
between landscape features and their repre-
sentation in digital form. Also, students
can determine whether any site-specific
problems exist, such as difficult access that
could inhibit field checking the data base.

proximately 20 students and 4 GRAs in
four projects presents a significant chal-
lenge in project control. Clearly, strong
management is needed to ensure data base
quality and to keep the project on sched-
ule. Having clearly defined and well-under-
stood responsibilities and maintaining good
communication among participants are es-
sential to the project's success. Communi-
cation is facilitated by regular planning
meetings between the instructor and the
GRAs and biweekly team meetings during
the laboratory sessions to discuss the
project's status and any problems die stu-
dents may have.
The GIS applications course culminates
in the preparation and presentation of
group and individual modeling reports. To
satisfy the group requirement for the
course, each student team defines the con-
tents of the report, agrees on individual re-
sponsibilities for the presentation, performs
one or more dry runs of the report, and pre-
sents the results in oral and written form.
In their group reports, students are encour-
aged to give a projeci overview, describe
the processes they followed m developing
the data base, and discuss any special prob-
lems and recommendations for additional
project work. When the oral reports are
given, interested faculty, students, clients,
and other members of the public are in-
vited to attend. Typically, the presentations
are given in a highly professional manner
complete with slides and poster-size
displays.
IHITEHFACIHIB
GIS education with
funded research
must be
accomplished
within a curricular
framework.
The other student obligation is the indi-
vidual modeling project. To complete this
requirement, each student applies a model
of his or her choice (deterministic or proba-
bilistic. and physical or human) to the data
base developed by their team The end prod-
uct is a poster display appropriate for a
professional conference, as well as written
and oral reports. The emphasis for the in-
dividual project is to integrate scientific
modeling and GIS and articulate the results
to the instructor, other class members, and
interested persons who may wish to attend
the presentation.
Examples of projects include siting hik-
ing and riding trails in a state park, mea-
uring the effect on sensitive plant species
of releasing reclaimed water into a natural
stream, and modeling the erosion caused
by using off-highway vehicles.
•UMMMO UP
The GIS Applications course IISDSU dem-
onstrates how university instruction and
grant and contract research can be inte-
grated in a GIS curriculum with benefits to
students, faculty, and funding agencies.
Those benefits are exemplified by the de-
partment's contract with the State of Cali-
fornia's Department of Paries and Recrea-
tion, Off-Highway Vehicle Division. This
project will result in a comprehensive data
base that will be used by park managers to
monitor the environmental impacts of off-
highway vehicles. Students working on
this project learn about all phases of the
GIS process, from collecting data to output-
ting hard copy. Finally, the project's prin-
cipal investigators, who are faculty mem-
bers, gain additional GIS experience that
can be passed on to future students.

Existing and planned projects for the NMED/SWQB Data Center.
The major, current project at our office is to achieve 6IS
capability for. our existing databases, which include the public
wells database (see page 1, #1, on the accompanying paper, "Ground
Water Quality Data Sources at the NMED"); the groundwater (GW)
discharge plan, (pg 1, *2, usually referred to as the" GW permit
database); the landfills database (pg4f #1); the CERCLA database
(pg 5, middle #1); and the Hazardous waste database (pg3, #1).
Our underground storage tank data (pg 5, bottom <1) does not have
lat/long information at present, but may be added soon. The
Surface Water Quality Bureau (SWQB) has less extensive in-house
database experience, but has achieved great capability and has
extensive historical records on the US EPA Storet national database
in Research Triangle Park^ NC. SWQB in-house PC databases include
a surface water use attainability dataset and an NPDES discharge
permit database.
For the mid-term we would like to achieve em expanded GIS
capability for our surface water sections as well. Other projects
still in the discussion stage include digitizing the aquifer
vulnerability maps (pg 6, #4, we have on-hand, one paper map per
NM county); and developing a wellhead protection GIS database.
The DOE oversight programs intend to use GIS. We would like to
coordinate with them as they develop their procedures.
Hardware and software on Band
Please refer to the accompanying list of hardware and software for
specific details. We use a Data General Aviion 300-series
workstation with about 24 MB RAM, and two EDs totalling about 1.3
GB of Btorage, running X-Windows and Arc/Info ver 6.1. We have an
Altec digitizer, a Houston Instruments Plotter, and an HP Color
Printer. The Aviion is networked to our other Data General mini
computers and will soon be connected to a network of ED personal
computers. The mini and the PC6 currently contain the databases
of several surface and groundwater sections. We hope to link those
systems with Arc/Info on our workstation and with Arc/View on the
PCs so that all of our data is available to whichever staff can use
it.
The data center also contains a 486 PC running DOS 5.0, Windows 3.1
and programs such as Lotus 123, Design Cad 2-D, and several
graphing and modeling programs. We may install AutoCadd vl2 in
the near future.

FY 1993 EPA/STATE WORK PLAN AGREEMENT
CLEAN WATER ACT SECTION 106-GROUND WATER
I.	Overall Objective
The objective of developing the New Mexico Comprehensive Ground
Water Protection Program is incorporated into this work plan. The
CSGWPP strategic activity specified by the draft CSCWPP Guidance
is identified for each task. In FY 1933 and succeeding years, New
Mexico hopes to make use of CWA 106-ground water funding to further
develop and implement a comprehensive program. Additionally, the
State hopes to assume funding responsibility for ongoing programs
initially generated using CWA 106 funds. Pending availability of
state funds, certain ongoing activities must continue as CWA 106-
funded projects.
II.	Program Elements

C. Agricultural Chemicals
Work Element A: Planning and Program Development
1. Comprehensive Ground Water Protection Program Development
A Comprehensive Water Resources Management Program is a fundamental
necessity in an arid state. At present, there are 13 State
governmental agencies whose actions directly or indirectly affect
New Mexico ground water. Within the New Mexico Environment
Department there are 21 programs, both state and federally
mandated, with the potential to affect the state's ground water.
The need for such a program is discussed in the New Mexico State
Ground Water Profile.
In addition to direct point and nonpoint sources of pollutants,
interactions between surface and ground water can compromise
otherwise pristine water resources. In a very real sense, all
environmental media are interconnected, and a total resource
management program must consider those interactions.
A first step in developing a program to manage the total water
resource is to develop a Comprehensive State Ground Water
Protection Program which would integrate or coordinate all state
ground water protection activities in New Mexico and provide a

GROUND HATER QUALITY DATA SOURCES
at the
HM ENVIRONMENT DEPARTMENT
Prepared by Natalie Keller
and Michael Gallagher
Evaluation & Planning Section
Surface Water Quality Bureau
1/92
The NM Environment Department (NMED) has a number of ground water
related databases and files. These data sets contain information
about ground water quality, as well as known and potential
contamination sources. The following is a list of these data
sources by program.
Oround Hater Protection and Remediation Bureau
1.	Public water supplies. Richard Asbury 524-6300
The Drinking Hater Section has computerized its public water
supply data management system. The Public Hater System
Inventory stored in dBASE IV contains information on each
system, including all drinking water quality results.
Numerous reports can be generated by the computer system, such
as information on sampling schedules and contaminant level
violations. The above information is currently being entered
into an IBM PS/2 microcomputer in NMED's Central Office.
There are plans to transfer this database to Oracle software
on NMED's Data General minicomputer. (Richard Asbury,
personal communication, December 1990.)
Information dealing with microbiological and turbidity
reporting statewide is stored on an IBM PC in the NMED Las
Cruces District Office.	(Richard Asbury, personal
communication, December 1990.)
2.	Discharge plans. Chuck Thomas 827-0652
The Ground Hater Section maintains a discharge plan database
on an IBM PS/2 using dBASE III+ software. This database is
in the process of being transferred to Oracle software on
NMED'8 Data General minicomputer. The Discharge Plan Tracking
System allows for the storing, cataloging, cross-referencing
and retrieving of data pertinent to discharge plan
administration and compliance tracking information. Location
information along with facility type, means of discharge,
monitoring requirements and compliance are tracked. The

system allows NMED to identify those dischargers failing to
adhere to reporting requirement guidelines and thus results
in better compliance with State ground water protection
regulations. Ground water quality monitoring data from
discharge plan facilities is largely stored in hardcopy files.
(John Parker, personal communication, December 1990.)
3 v Underground Injection Control Program. Ernie Rebuck 827-2945
The Underground Injection Control Program in the Ground Water
Section maintains a database of underground injection sources
on an IBM PS/2 using dBASE III+ software. The- database
contains information about the locations of these injection
sources, types of sources, waste stream characteristics,
injection intervals and geologic formation characteristics.
Most of these sources are class 5 "wells" (including various
types of disposal wells, miscellaneous wells and other
facilities such as septic tank leach fields not ordinarily
thought of as "wells"). (John Parker, personal communication,
December 1990.)
4.	Septic systems. Delbert Bell	827-2788
The Liquid Waste Section maintains information on permitted
and registered domestic septic systems. These data are
computerized and are maintained in each of the four NMED
District Offices, rather than at the Central Office. Data on
system type, location, depth to water and lot size are some
of the parameters collected. (Pat Hanson, personal
communication, December 1990.)
5.	Ground water contamination incidents. Natalie Keller 8 2 7-
2912
The Technical Services Section maintains a database of ground
water contamination incidents on an IBM PC using dBASE III+
software. There are well over 1500 documented ground water
contamination sites involving over 140 public wells and over
1300 private wells in New Mexico. Information about each
incident includes location, source of contamination, type of
contaminant and the status of cleanup activity.
6.	Unauthorized discharges. Bill Bartels 827-2981
The Technical Services Section maintains an unauthorized
discharge and complaint database on NMED's Data General
minicomputer using Oracle software. This database allows
staff to track the types of incidents reported, their
potential to contaminate ground water and the status of their
compliance with the New Mexico Water Quality Control
Commission regulations. Among information entered is the
location, contaminants and actions taken on an incident. This
information was formerly kept in hard copy files.
n/at 7. Ground water contamination cases. The Technical Services
Section also maintains a ground water contamination case
2

-------
docket system using Oracle software on NMED's Data
General minicomputer. The case docket system tracks the
status of all ground water contamination cases being
handled by the Section.
8.	Water Fairs. Barb Giesler 827-2732
The Technical Services Section has collected a large amount
of data from their Water Fair program. Water samples from
private wells are tested for pH, conductivity, temperature,
organic vapor, nitrate and iron. Further tests for manganese,
sulfate and sulfides are performed if deemed necessary. Some
of these data have been entered into one of two databases
using dBASE III+ software on an IBM PC. The rest of the data
reside in hardcopy files.
9.	Albuquerque South Valley study. A cooperative agreement
between the U. S. Geological Survey (USGS) and NMED was
entered into for the computer analysis of water quality data
from the Albuquerque South Valley that was collected for a
special study conducted during the mid-1980s. USGS's PRIME
minicomputer and the U. S. Environmental Protection Agency's
(EPA's) IBM mainframe computer were used for the data
analysis. The results are available in two NMED publications
(1 and 2). The data are stored on EPA's IBM mainframe
computer in North Carolina. They may also be available from
USGS Water Resources Division in Albuquerque.
10.	Uranium mines and millB study. In 1980 a report was prepared
presenting data obtained from effluent samples collected by
NMED during 1977 - 1979 at all New Mexico uranium mines known
to be undergoing dewatering and at all operating uranium mills
(3).
11.	STORET. EPA & USGS
The U. S. Environmental Protection Agency's (EPA's) STORET
water quality database contains some ground water quality data
for New Mexico. Very little of NMED's ground water data,
however, are stored on this system. The ground water data
collected for the Grants Mineral Belt Study done by NMED are
stored on STORET. The U. S. Geological Survey's ground water
quality data are periodically transferred from the Survey's
National database to STORET.
formerly databases of the Toxic Sites Bureau:
12.	Superfund sites. Randy Merker 827-0078
The Superfund Section tracks information about potential
Superfund sites in New Mexico. EPA maintains a Comprehensive
Environmental Response, Compensation and Liability Information
System (CERCLIS) database that holds information on these
sites. Information stored in thiB database includes location
and the status of investigations at the sites. (Steve Cary,

13.	Natural resource damages inventory. Dennis McQuillan 827-
2831.
The Remediation Section maintains a database of natural
resource damages in New Mexico due to hazardous materials.
The database contains information about contaminated ground
water, soil, surface water, air, flora, fauna, the food chain
and human exposure. Information about the location, source
of contamination and type of contaminant is maintained.
(Dennis McQuillan, personal communication, December 1990.)
14.	Biannual report on hazardous waste. Jim Mullany 827-0212.
The Bureau has entered the 1987 Biannual Report on Hazardous
Waste onto the Focus database on an IBM PC. This database
contains information about large quantity generators of RCRA
waste. Information tracked includes location of facility,
type of waBte and amount, as well as information on
transporters of waste and management of waste on site. (Jim
Mullany, personal communication, December 1990.)
Hazardous and Radioactive Materials Bureau
1.	Hazardous waste facilities. Herbert Grover 827-4300 & Bruce
Swanton 827-4300
The Hazardous Waste Program tracks enforcement and permitting
information for facilities engaged in hazardous waste
activities in Mew Mexico. This information, as well as
information about site location, owner/operator and types of
hazardous waste managed is maintained in the U. S.
Environmental Protection Agency' s (EPA's) Hazardous Waste Data
Management System (HWDMS) on EPA's mainframe computer system
in North Carolina. (EPA is in the process of changing over
to a database called RCRIS which tracks the same information.)
There are about 15 sites that treat, store or dispose of large
quantities of hazardous waste in New Mexico, and about 100
facilities that generate or transport large quantities of
waste. The Program has also developed a limited database on
small quantity generators of hazardous waste within the State.
This database is stored using dBASE III+ software on a
personal computer and contains information on approximately
1400 facilities. (Boyd Hamilton, personal communication,
December 1990.)
2.	HIPP shipments. The Radioactive Waste Section has access to
the U. S. Department of Energy's (DOE's) TRANSCOM database
which tracks the status of WIPP (Waste Isolation Pilot
Project) shipments. Information maintained in this database
includes location, type of material, quantity, time shipped
and emergency response measures. (Bobby Lopez, personal

Solid Waste Bureau
1.	Landfills. Dave Duran 827-2950
The Bureau maintains a registered landfill database on an IBM
PC using dBASE III+ software. This database contains
information about landfills (both closed and active) that
handle domestic and commercial waste. More records are being
added to this database as the new solid waste regulations call
for registration of industrial landfills as well. Information
in this database includes location, type of landfill, surface
drainage, soil type, depth to water, age of landfill, wells
in proximity, nearby water courses and types of waste in the
landfill. There are plans to transfer this database to Oracle
software on NMED's Data General minicomputer. (Randy Gabriel,
personal communication, December 1990.)
2.	PCBs, asbestos, recycling. The Bureau has plans to develop
a polychlorinated biphenyls (PCBs) database that would contain
information about facility inspections as well as complaints
of spills or other violations The same type of database is
planned for asbestos information. The Bureau also would like
to develop a database for recycling information and activities
in Mew Mexico. Another planned database would be used to
store information related to household hazardous waste.
(Chuck Bules and Barbara Eoditschek, personal communication,
February 1990.)
3.	Landfill siting 6IS project. In 1989, the solid waste program
executed a demonstration project using GIS technology for
identifying potential landfill sites in the Albuguergue-Belen

GIS AND DIRECTLY RELATED WATER RESOURCE HOLDINGS OF THE
NEW MEXICO ENGINEERING RESEARCH INSTITUTE (NMERI) FOR
SOUTHERN NEW MEXICO
Introduction/Background
Hie New Mexico Engineering Research Institute (NMERI) is a branch of the University of
New Mexico's College of Engineering. NMERI conducts engineering and scientific research,
development, testing, and evaluation. Technical Assistance and expert services are also essential
NMERI tasks performed in support of the University's three-part mission: education, research,
and public service.
With over 25 years of research experience, NMERI serves the needs of clients from the
public and private sectors and enjoys an international reputation in many specialized areas.
NMERI GIS Capabilities
The New Mexico Engineering Research Institute has complete in-house capabilities to
develop data intensive GIS applications. We currendy utilize the New Mexico state standard for
GIS software, Arc/Info version 6.1. We also have on site, two Digital Equipment Corporation
(DEC), 5000 series Unix/RISC work-stations and a variety of other data processing and
networking systems. Our staff includes a practicing geographer, engineers, and senior software
developers with specific expertise in the design and development of GIS based data systems and
other data intensive information systems. Additionally, NMERI has ongoing cooperative
agreements with other University of New Mexico entities which augment and round-out our data
development and networking capabilities.
NMERI Relevant GIS Experience
NMERI has specific relevant experience in the development of GIS based data systems.
We have developed GIS applications for clients which include the United States Department of
Agriculture, the U.S. Army Corp of Engineers, the City of Albuquerque, NM, the New Mexico
Economic Development Department, the United States Army, the U.S. Fish and Wildlife Service,
the New Mexico Interstate Stream Commission, the U.S. Soil Conservation Service (SCS), and
the Federal Emergency Management Agency (FEMA)
NMERI has administered, since 1987, the Resource Geographic Information System
(RGIS) Program, a statewide GIS initiative established by the New Mexico State Legislature.

NMERI personnel inventoried and produced, the first existing catalog of digital data known
to reside in the state of New Mexico as part of the RGIS Program.
NMERI continues the on-going development of a GIS based multi-agency system which
effectively shares water related data bases and promotes water related data exchange between state
and federal agencies within New Mexico.
NMERI personnel were instrumental in developing the current set of GIS standards and
guidelines for New Mexico.
NMERI GIS and Related Water Resource Holdings and Activities:
The Flood Protection Inventory Needs Geographic Information System (GIS)
Application (tentatively planned to be referred to as the New Mexico Water
Resource Information System (NM WRIS) in 1993 as it is expanded)
Enclosed as an attachment is a final report presented to the U.S. Fish & Wildlife Service
and sponsored by the Corp of Engineers (COE) and New Mexico Interstate Stream Commission,
entitled THE FLOOD PROTECTION INVENTORY NEEDS GEOGRAPHIC INFORMATION
SYSTEM APPLICATION. Work performed in the development of this GIS application will
eventually be incorporated into New Mexico's State Water Plan.
This report summarizes a GIS application for accessing all flood protection related COE
Reports compiled for projects between 1974 and 1992 and Federal Emergency Management
Agency (FEMA) reports for all reports on record, by spatially indexed GIS query functions.
Within this Arc/Info based application a user can query COE or FEMA reports prepared at three
levels of geography; community, county, or by river basin. GIS coverages used for this
application include: New Mexico County Boundaries and Names, USGS Geographic Names
Information System (GNIS) used to locate communities, the USGS 8-digit code Hydrologic Unit
boundaries, River Basin boundaries and their names, and Regional Water Planning district
boundaries and their respective names.
The database cqntains useful information for communities, regional agencies, civil defense
(emergency response) agencies, and water resource managers.. Because of its orientation to
locational reference (the reports of various sites and areas distributed throughout New Mexico) the
Flood Protection Inventory lends itself well to the display and query capabilities which GIS
software utilities offer. This spatial referencing mechanism to water resource based bibliographic
references brings a new paradigm to collective information access not previously seen in New
Mexico. Hopefully this new approach to information retrieval will serve as a foundation for other
water resource related databases which reside within the state.

Planned Additions to The NM Water Resource Information System for 1993
As was the original intent of the Flood Protection Needs Inventory GIS application,
another major contributor's holdings will be brought into the system in 1993. The Soil
Conservation Service's Albuquerque office will be contributing four record types to the WRIS in
FY93. These will include Snowpack reports, Soil Survey Report(s) status, Resource and
Conservation Development Projects, and Basin Reports.
In addition to added record types, NMERI will add menu hooks for future inclusion of the
USGS's Ground Water Site Inventory, EPA River Reach-3 file coverages, EPA's Toxic Chemical
Release Inventory, and when it is completed, the Soil Conservation Service's 11 digit Sub-Basin
Watershed coverage, to the application. Other relevant coverages may be added as requested.
NMERI will reconstruct the WRIS application to fully take advantage of Arc/Info 6.1 thread and
cursor functions for enhanced user interface performance.
NMERI Infrastructure Development Assistance Program (IDAP) Activities
The Infrastructure Development Assistance Program (IDAP) was created in 1988 to
address infrastructure problems in New Mexico (see enclosed program description). The program
is administered by NMERI and by legislative appropriation. The purpose of the IDAP is to
strengthen local infrastructure management capabilities through a statewide program of technical
assistance, training, and technical development The program is intended to mobilize appropriate
public and private resources to make additional professional assistance available to towns,
counties, and other public bodies with infrastructure management responsibilities. IDAP programs
are coordinated by a broad-based Infrastructure Council composed of representatives from public
and private sector organizations.
Currently as a part of the IDAP program's activities, NMERI is actively working with
several communities in New Mexico, many in southern New Mexico, to assist with water and
wastewater planning. I have enclosed a memorandum from our community planner summarizing
our most current IDAP activities in the southern part of the state. Although not currently linked to
our WRIS GIS application, reports and other helpful information may be associated to their
respective community locations by use of the USGS Geographic Names Information System
(GNIS) or by editing in known locations, i.e., colonias locations captured by GPS measurements
or satellite imagery.
Another useful IDAP produced reference to parties interested in development of GIS in the
border area is the Acequia Sourcebook. Please find enclosed a brief overview of THE ACEQUIA
SOURCEBOOK FOR your information (copies are available upon request).

SECTION I
INTRODUCTION
A. INTRODUCTION
Recently, the Corps of Engineers Southwest Division, Albuquerque District (CESWA)
completed and delivered the first compilation of the New Mexico Statewide Inventory of Flood
Protection Needs, in report and database format, (hereinafter to be referred to as "the Flood
Protection Inventory" (FPI)) to the New Mexico Interstate Stream Commission as pan of the
Planning Assistance to States (PAS) Program (Reference 1). Established by the Water Resources
Development Act of 1974, the PAS Program provides a mechanism for the Corps of Engineers
(COE) to provide assistance to states for situations that are unique, such as preparing
comprehensive state water plans.
The FPI currently resides in a personal computer based Relational Database Management
System (RDMS), dBasein® Plus, and contains flood control study and project report references
which have been conducted throughout New Mexico since 1974. This includes Federal
Emergency Management Agency, (FEMA), flood insurance studies and a variety of Corp of.
Engineers Flood Protection Study Data Reports. In its current dBaselD® Plus format the
inventory is an extremely useful reporting tool; however, it does not have the capability to display
and query the locations of each project in a mapped spatial format. The inventory currently does
have the spatial references: community names, county names, and river basin names, which can
serve as links from the FPI data to a spatially referenced Geographic Information System (G1S)
based application.
This task documented herein applied the process of geographically linking the original data
sets to a spatial reference, making the original data sets suitable for use in a GIS. Geographic
linking or "geolinkmg", as referred to here, is the process of relating a data set with a "soft" spatial
reference Q.e. community name) to a data set with a "hard" spatial reference (Le. latitude,
longitude). The link is through the use of data elements common to both data sets and database
techniques known as relational operations. This technique combined die data elements from both
data sets to locate and describe a place of interest In this case the community, county, and river
basin names found in the FPI database were used to geolink to the digital United States Geological
Survey (USGS) Geographic Names Information System (GNIS), the County Boundary, and
aggregated Hydrologic Unit GIS coverages respectively for New Mexico. This allowed the

accurate mapping of these study sites and areas. Having this comprehensive spatial and tabular
darabase pertaining to statewide flood protection studies will contribute significantly to many of the
United States Rsh and Wildlife (USFWS) Water Rights Program manager's decision making
needs as well as other water resource managers in New Mexico.
B. BACKGROUND
The FPI database was originally requested by the Interstate Stream Commission from the
CESWA for incorporation into a revised state water plan. As mentioned earlier, this agreement
was established as pan of the PAS Program, which was established by Congress to enable states
to use GOEs planning expertise in the preparation of comprehensive plans for the development,
utilization, and conservation of the water and related land resources of drainage basins located
within the boundaries of a state. At the request of the Albuquerque District COEs Planning
Department through the efforts of the USFWS, the New Mexico Engineering Research Institute
(NMERI) was commissioned to convert the FPI database to a menu driven CIS based report query
application.
As taken from Reference 1:
"The database consists of Study Data repots and FEMA Data reports. The
Study Data report includes pertinent data from completed COEs planning studies
conducted for communities, counties, or river basins that identify flooding
problems and solutions. The FEMA Data report consists of National Flood
Insurance Program (NFIP) information for communities in New Mexico.
A computer program titled Planning Assistance to States (PAS) was
developed in Fort Worth Texas District for the Texas Statewide Inventory of Flood
Protection Needs compiled by the Fan Worth District in partnership with the Texas
Water Development Board The program was developed on the microcomputer to
assist in the compilation of the inventory data. The PAS System is written in
dBasem Plus® and is a full feature, menu driven, user friendly, database
management system."
The FPI contains useful information for communities, regional agencies, civil defense
(emergency response) agencies, and water resource managers. Because of its orientation to
locational reference (the reports of various sites and areas distributed throughout New Mexico) the
FPI lends itself well to the display and query capabilities which GIS software utilities offer. This

spatial referencing mechanism to water resource based bibliographic references brings a new
paradigm to collective information access not previously seen in New Mexico. Hopefully this new
approach to information retrieval will serve as a foundation for other water resource related
databases which reside within the state.
C.	OBJECTIVES
The primary objective of the FPI GIS task described herein was to convert the existing
non-GIS based FPI into a GIS based tool for use in spatially querying and analyzing the flood
protection data currently available in New Mexico. The following achieved this conversion:
1.	The original data sets contained in the FPI were used to avoid the cost of
regenerating the data.
2.	The FPI data sets were restructured, as required, to be suitable for use in a GIS.
3.	Public domain GIS data sets were acquired for use in spatially locating the FPI
study sites.
4.	The FPI data sets were geographically linked with the GIS data sets to allow GIS
manipulation of the FPI data.
5 Designed and implemented a GIS application to allow spatial query and analysis of
the FPI data.
6. Retained, wherever possible, the current functionality of the original FPI data.
D.	APPROACH
The approach taken to develop the FPI GIS application involved a direct determination of
current capabilities and then a projection of the enhancements possible in a GIS. First, the current
FPI functionality and data contents were evaluated using an in-house copy of the FPL Second, an
assessment was made of the added functionality and capabilities possible in a GIS implementation
of this type of database. Third, a determination was made of the steps needed to develop and
implement the GIS with it's related software, datascts, data structures, and data layers. Finally, a
definition of the development schedule and sequence was developed.

DATABASE PREPARATION
The GIS dawhac* for this task incorporated two primary data types, first, die attribute data,
comprised of the study site summaries and repots residing in the FPI database on a personal
computer, and the spatial data, comprised of ARCyiNFO® coverages available for use on a
UNIX based workstation. The development and implementation platform chosen for this
application was ARC7INFO® GIS software running on a DEC Station 5000/200 workstation.
This imposed a requirement for all data to be suitable for this environment. Appendix A contains
the program and menu script listing developed during this task.
A.	ATTRIBUTE DATA
The first data type, the attribute data, consisted of three data sets, the communities data set,
also called the summary data set, (FLOCOMKLDBF), the Army COEs Site Study data set,
(FLOSSWA.DBF), and the FEMA Site Study data set, (FLOFSWADBF). At the onset of this
task, these three data sets were contained in a dBaseHI Plus® database in die internal database
format These data sets were extracted from the dBaselH Plus® environment in an ASCII format
using internal dBascIII Plus® functions, and transmitted via Local Area Network to the
workstation. Once in the workstation environment, the data was conditioned for insertion into the
GIS Hatahac^ management system: INFO®. Three data structures designed to accommodate the
FPI data were then implemented in the GIS and the data was imported into these data structures
through the use of ARC/INFO® utilities. This now made the FPI data accessible in a GIS
environment. Appendix B contains sample reports which are available within the>FPI GIS
application.
B.	SPATIAL DATA
The second data type, the spatial data, consisted of three ARC/INFO® coverages available
in the public domain: the USGS GN1S, the Hydrologic Unit thematic coverage, and the County
Boundary coverage. Also, one converted AutoCAD® coverage of water planning areas with
associated names, provided by the Interstate Steam Commission, was incorporated. All mapped
coverages used were available at a scale of 1:500,000 and covered the geographic extent of New
Mexico (Appendix Q. For more detailed documentation on each of these coverages see Appendix
D.

USEPA Office of Water (WH-547). US-Modco Border CIS Catalog attachment July 1993.
Page 139
-------
The USGS GNIS required some modification to accommodate the use of some "unofficial"
names in the original FPI data and to correct some deficiencies in the current GNIS (locating
communities not found in the GNIS).
The Hydrologic Unit coverage required some enhancement to allow aggregation of the
hydrologic units into the major river basins. The aggregated hydrologic units were then used to
generate a river basin coverage.
The County Boundary coverage was used as it was received.
As was mentioned, the Statewide Regional Water Planning Areas coverage, was obtained
from the Interstate Steam Commission in an AutoCAD® format. This coverage was converted into
a DXF format using an internal AutoCAD0 function and then convened into ARC/INFO®
coverages using ARC/INFO0 utilities. Two data layers were extracted and convened: the planning
area boundaries and their names.
Appendix C contains hard copy maps of the Regional Water Planning Areas coverage, die
Counties Boundaries coverage, the River Basin coverage, and the River Basin Coverage.
C.	RELATE TABLES
The last significant data preparation task was the generation of a data table which allowed
the CIS to relate the spatial data to the attribute data. This so called "relate table" defines the six
data table relationships required for geolinking. This relate table is an original data set developed
for this application.
D.	SUMMARY
The attribute data was geolinked via the relate tables to the spatial data. From this linkage
the ability to spatially access the original FPI data through a GIS application was developed as the
user interface.

USER INTERFACE
A.	DESCRIPTION
The user interface for this application is a menu driven combination of graphic and text
windows displayed simultaneously on the user terminal. The user interacts with die menus and
display windows through the use of a mouse activated cursor. Menu selection or study site
designation is achieved by "pointing and clicking" on the particular selection. To select an area for
zooming, the user points and clicks on two diagonal points boufidingihe area of interest.
B.	MENU OPTIONS
User options may be used in any order or combination and for either die entire state or for
any portion of the state, that is: any zoomed area. Table 1 list specifies and describes the user
options.

SECTION IV
CONCLUSIONS AND RECOMMENDATIONS
A.	CONCLUSIONS
All six of the stated objectives were completed as part of the development of the FPIGIS
application. With the successful completion of this project it is clear that GIS is well suited to this
application of access to bibliographic information. GIS databases like the FPI, when converted to
a GIS application, hold tremendous potential uses for water resource and other natural resource
managers.
B.	RECOMMENDATIONS
After initial use and evaluation of the FPI GIS application, as has been summarized here,
additional enhancements which might be added to it include the following:
1.	Add explanation text as found in report
2.	Provide a mechanism to capture and print the contents of a selected window session to a
standard postscript printer
3.	Add base themes for enhanced geographic reference Le., Rivers and Roads
4.	Breakout Real Property from non-infrastructure producing studies in COE reports
5.	Prepare and /or include Soil Conservation Service 11 digit code watersheds and
incorporate into reporting breakdown.
After having successfully completed the conversion of the FPI into a user friendly GIS
based information access system it is clear that its utility could confidently be expanded to include
many other valuable databases. These might include:
1.	Interstate Stream Commission's Water Use and Ground Water Report Database
2.	USGS Reports
3.	Soil Conservation Service Snow Pack and Infrastructure Reports
4.	Water Resource Research Institute (WRRI) Reports
5.	Bureau of Reclamation Reports

PREFACE
The Aceouia Sourcebook was made possible by the
Infrastructure' Development Assistance Program at the New Mexico
Engineering Research Institute, University of New Mexico. The
purpose of the sourcebook is to assist the community ditch
associations of New Mexico locate sources of funding, technical
assistance and information regarding infrastructure problems,
water resources management, and conservation planning. The
sections in the sourcebook were designed in a manner which allows
the associations to add, update or delete information as the
assistance programs and their requirements change year to year.
The sourcebook contains information on the various federal,
state, and regional assistance programs available to New Mexico's
acequia associations. Major and widely known sources as well as
dozens of related, and perhaps underutilized, sources were included.
The descriptive information regarding each of the sources was
derived from agency materials such as annual reports, pamphets.
program annoucements, application kits, project plans and other
public information documents. Where necessary, telephone or
personal interviews were conducted to amplify the printed
materials or to clarify specific points.
Care was taken to make the sourcebook entries as accurate and
updated as possible through the summer of 1990. In all cases,
however, the users of the sourcebook should contact the designated
office or agency for more information, especially regarding

eligibility rules, application procedures, deadlines, and other
requirements.
The Aceauia Sourcebook is available at no charge to the
community ditch associations of New Mexico as long as copies on
inventory continue to last. Reprints at a nominal cost can always be
arranged after the initial supply is exhausted. In addition, the
sourcebook can be shared with larger audiences such as at
workshops organized by local, regional and statewide acequia
organizations. For assistance in this regard or for more information
about the sourcebook, please write to: Jos6 A. Rivera, Southwest
Hispanic Research Institute, University of New Mexico, 87131. If
you prefer to call by telephone, the number in Albuquerque is 277-

MEMORANDUM
TO: John Peterson - GIS Coordinator
FROM:ichard G. Chavez - Community Planner
DATE: February 1, 1993
SUBJECT: Present Activities in southern New Mexico
Through the Rural Community Assistance Corporation (RCAC) I am currently working
with five communities in southern New Mexico.
The communities in question are Truth or Consequences, Garfieid, Salem, Lordsburg,
and Hanover.
T or C and Lordsburg are the only incorporated communities that I am assisting. My
assistance with these two communities consist of inventorying their water and
wastewater facilities for current and future facility needs, technical assistance will also
include identifying federal and state funding sources, and a review of the user rates in
order to asses user contributions for any loans that might need to be secured.
The technical assistance for Garfield and Hanover will be quite similar in that we will be
identifying current and future needs of their water system, funding sources, and user
rate reviews.
My work with Salem will involve trying to identify water and wastewater needs, services
and facilities in addition to a more broad perspective of community development which
would include community organization for the purpose of identifying and prioritizing
community facility needs.
Another major project will involve the coordination of a workshop on "Alternative
Wastewater Treatments for Small Systems". This workshop will involve approximately
six communities which mostly likely will be colonias.* Material will also be provided in
Spanish for the participants.
At this point in time, these are the only project I have going in southern New Mexico.

become available they will also be incorporated'
Into the RGIS resource library. One of the
outstamfcng features ol the census Is that data
wiH be available down to e vary smal geo-
graphic aria Thau data Inciuda median
household Income, race and ethnicity, and
number of households. Civilian labor force by
county, nonagrkuttursl employment, unem-
ployment rates by county, per capita income by
county, gross receipts by sector, and birth and
death rates by county are hilt a few of the
coverages available from this extensive state-
wide dstsbase.
Natural and Cultural Resource Covereoea
Fifteen natural and cultural resource coverages
are available from the resource library. These
small scale, statewide coverages were dioitlied
from published maps acquired from federal
agencies such es the US Geological Survey. In-
cluded in the library are standard base map
coverages such as state outline, county bound-
arias, transportation network, and populated
places. Thematic coverages such as veeetation
and soBs are also evaBable.

Tasks 4 -10: Regional Environmental Information Systems
Overview: This task proposes the development of regional, computer-based
environmental information systems. These systems will offer a regional network
for data sharing and application-specific archives and functions on a regional and
local basis. They will be connected to the national-level EPA Directory and Data
Access System, as well as EOSDIS, SEDAC, and the CIESIN's Information
Cooperative.
CIESIN will establish a Users Working Group to provide advice on
prioritization of data and services to help ensure that investment into data access is
driven by a broad spectrum of science and policy needs—both EPA and non-EPA
alike. The Users Working Group will include representatives from both the Federal
and non-Federal scientific, engineering, and policy communities. A goal of the
Working Group will be to encourage the identification, assembly, documentation,
and preservation of environmental data, and to help enable EPA to present to the
scientific and policy communities an integrated, comprehensive view of the
Agency's collective holdings, supporting policies and services to users.
The Regional Environmental Information Systems will be developed on a
regional basis and will consist of networks of data holders, EPA and non-EPA alike,
that maintain data archives pertinent to EPA regional and local concerns. These
data archives will be networked in a directory and information access system
architecture similar to the national-level EPA system that will be prototyped in Task
2. Directory as well as inventory access functions will be available. An EPA regional
program office will serve as a central node for the regional network, providing its
members connectivity to the national-level EPA system along with its extended
network. This relationship is presented in Figure 5 (page 25).
Within each region, an application-specific distributed data archive and
information system will be defined and developed. These systems will provide
access to application-specific archives distributed within each region. In this
concept, individual data holders develop and maintain their own data archives.
The ultimate functionality of the regional environmental information
systems will be driven by regional and local EPA information requirements, and
subject to data availability. They potentially could present users a directory of
available data and information, a means of access to that data, tools for data
manipulation and analysis, and the capability to display the resultant information.
Geographical or spatial context will be maintained for analysis and display by the
incorporation of Geographic Information System (GIS) capabilities.
A common development model will be used in the prototyping of all
regional systems. This model incorporates (a) survey of regional data sets, (b)
documentation of the survey, (c) development of regional network organizations,
(d) directory system prototype engineering and architecture design, (e) prototype

development, (f) data integration demonstration definition, (g) data development,
and (h) development of the regional distributed data application system (Figure 7).
A brief discussion of these activities is as follows:
Survey of Regional Data Sets
A survey will be performed of non-EPA data sets of regional and local
significance. (EPA data sets will have been surveyed in Task 1.) Information
obtained from this survey will (a) provide input to regional directory development,
(b) help establish the scope of the regional network, and (c) provide input to the
definition of the regional distributed data application-specific archive system and
data integration demonstration.
Documentation of Survey
Results of the survey will be entered into a "tracking" database. This database
will be designed to facilitate the development of directory entries.
Development of Prototype Network Organizations
Regional data holders will be prioritized as potential regional network
members with guidance from EPA User Working Groups. Once identified as
relevant, contact will be established, and details of network membership will be
worked out.
Regional Directory System Prototype Engineering and Architecture
This involves the definition of the regional network operations, and defining
the architecture of the system. This engineering work will precede actual
development of the Regional Directory System Prototype.
Prototype Development
Development activity includes establishing network connectivity; developing
directory entries, including the establishment of a controlled vocabulary, and the
writing of directory entries; installation and demonstration of the distributed
directory prototype between the region's central node and a member node;
investigation of level 0 inventory access potential; development of a file transfer
system for level 0 inventory access; installation and demonstration of level 0
inventory access with file transfer from the region's central node to a member node;
the investigation of level 3 inventory access potential; development of level 3
system compatibility; installation and demonstration of level 3 inventory access
between the region's central node and a system at a member node; and training for
the installed systems.
Data Integration Demonstration Definition
Pag* 190
USEPA OffiM gf Water (WH-547). US Mwdoo Bofdf OB Catalog attachment. July 1893.
-------
Definition of the data integration demonstration consists of defining the
information requirements, what data sets will be integrated, and how they will be
integrated. This demonstration project will be defined in conjunction with the
selection process of prototype network members with guidance from an EPA User
Working Group.
Data Development
Data development entails the activities of categorization of data for data
retrieval; data conditioning, putting the data into usable formats; and integration of
data and development of integration products. This work will be done in
conjunction with the development of a Regional Environmental Information
System.
Development of Regional Environmental Information System
Development of this system will allow users to utilize data archived at other
network locations for specific applications. The development process includes
system functional definition in response to EPA regional and local needs;
architecture and operational definition; system design; system development; test,
verification and installation; and demonstration. This development will build
upon available Environmental Information Systems such as CIESIN's Saginaw
Valley Watershed Regional Prototype.
All regions will not be developed concurrently. The Great Lakes region will
be used as a regional prototype, where most development activity will occur in FY
1993. The Chesapeake Bay and the Mexican-U.S. Border region development will be
initiated in FY 1993 with greater emphasis given to Chesapeake Bay. In FY 1994 the
Great Lakes region will be expanded, tested, and refined; the Chesapeake Bay and the
Mexican-U.S. regions will be prototyped; and network development in two
additional regions will be implemented. In FY 1995 continued expansion, testing
and refinement will be made of the Great Lakes, Chesapeake Bay and Mexican-U.S.
Border regions, the regions initiated in FY 1995 will be prototyped, and additional
regional development will be initiated. This, as all development, will be guided by
EPA User Working Groups. As systems for data access and integration are
developed for the Great Lakes and subsequent regions, they will be installed in other
regions where relevant.

Task 7: Inventory and integration of available information in the
Mexican-U.S. border area (September 1993 Implementation)
Background: The border area between Mexico and the United States is defined as
the zone within 100 km on either side of the political boundary of each country. It
stretches nearly 3200 km, or about 2000 miles, between the Gulf of Mexico and the
Pacific Ocean. More than 9.5 million people live in the border area, however over
95% of these people live in fourteen pairs of sister cities (Tijuana/San Diego,
Mexicali/Calexico, San Luis Rio Colorado/Yuma, Nogales/Nogales, Agua
Prieta/Douglas, Naco/Naco, Las Palomas/Columbus, Ciudad Juarez/El Paso,
Ojinaga/Presidio, Ciudad Acuna/Del Rio, Piedras Negras/Eagle Pass, Nuevo
Laredo/Laredo, Reynosa/McAllen, and Matamoros/Brownsville).
Even though the border area is divided into different political units,
including two countries, six Mexican states, and four U.S. states, it is—from many
perspectives, including the environmental—an undivided area. It will require an
integrated and coordinated approach to protect its future environmental quality and
#its future quality of life. The North American Free Trade Agreement (NAFTA)
states that one of its main purposes is to promote economic development and trade
expansion in a manner consistent with environmental protection and
P«9« 182

-------
conservation, and to promote environmentally sustainable development. Some say
that the trade accord could lead to increased pollution along the U.S. Mexican border
and the lowering of U.S. environmental and food safety standards. However,
William K. Reilly, while EPA Administrator, said that NAFTA would encourage
the trade-pact parties to harmonize their standards upwards to increase protection of
the environment and health.
At the present time, based on the available data, the most serious
environmental concerns are related to the concentrations of people and industry in
the fourteen border-area sister cities. Congestion, uncontrolled urban development,
and lack of basic public health and sanitation facilities have become significant
problems in many communities. At many places on the U.S. side of the border,
unincorporated communities, called colonias, have sprung up adjacent to towns
and cities. These colonias are characterized by substandard housing, inadequate
roads and drainage, and barely adequate water and sewer systems, if such systems
exist at all. For example, less than one percent of Texas colonias are served by
wastewater treatment systems. Most waste water from colonias goes into closed-end
ditches, pits, or outhouses. Groundwater contamination is therefore more likely to
occur than surface water contamination, except under high rainfall conditions.
When high rainfall conditions occur, contaminated waste water is likely to affect the
water quality downstream of the effluent.
Air quality in the border area is affected by agricultural activities and use of
pesticides and fertilizers, urban traffic congestion, toxic pollutants emitted from
small industries along both sides of the border, and open burning of solid wastes,
primarily on the Mexican side of the border. In addition, many people heat their
homes with wood- or refuse-burning stoves that emit toxic air pollutants.
It is difficult to quantify the extent to which these different sources of
pollution are contributing to exposure of the residents along the border, since the
existing monitoring is inadequate for this purpose (ref.: U.S. Environmental
Protection Agency and Secretaria de Desarrollo Urbano y Ecologia, Integrated
Environmental Plan for the Mexican-U.S. Border Area /First Stage, 1992-1994J). In
the Environmental Plan for the Mexican-U.S. Border Area, the need for increased
understanding of the environment was identified. One of the major objectives of
the first stage of the Environmental Plan (1992-1994) is to gain environmental
information, including quality of environmental resources, such as airsheds and
ground water, and the amount, concentrations, and sources of pollution in the area.
Purpose of Task 7: The goal of the task is to provide a regional environmental
information system capable of addressing targeted issues related to what has been
and is currently being done to characterize the exposure of the people living within
the Mexican-U.S. border region, and the extent to which people are being exposed,
the most significant routes of exposure, the sources of exposure, and the
relationship of these exposures to health risks. Communities need, and have a right
to know, that information, because it is the basis for informed judgments on the
USEPA Office of Water (WH-547). US-Mexico Border GIS Catalog attachment July 1883.

success of environmental protection efforts, and on the direction of future efforts. A
regional environmental information system would provide input into the U.S.
effort to ensure that domestic trade policies are environmentally sensitive and that
the U.S. environmental programs support free trade and sustainable growth.
Approach to Task 7: This task will follow the model for the creation of a Regional
Directory, Data Sharing Network and Information System for the U.S.-Mexico
Border Region. Development in FY 1993 will be limited to initiation of the survey
of appropriate regional EPA and non-EPA data sets.
Associated activities in the out-years will include:
•	CIESIN will act as a gateway between the participants in the Environmental Plan for
the Mexican-U.S. Border Area and CIESIN's Information Cooperative members,
providing for the exchange of border-area related data and information.
•	The participants in the Environmental Plan for the Mexican-U.S. Border Area will
have access to remote sensing data through CIESIN's Socioeconomic Data and
Applications Center (SEDAO.
•	C1ESIN will assist in the identification, collection, archiving, and dissemination of
specialized information relevant to environmental change investigators,
environmental change policy analysts, and the integration of interdisciplinary data
in the border area.
•	CIESIN will serve as a point of access to border-area data and information for those
who are outside of the area, especially for the domestic and international
environmental change science community.
•	CIESIN will be a source of Temote sensing expertise, Geographic Information System
(CIS) capability, data harmonization, and data integration capability for the
participants in the Environmental Plan for the Mexican-U.S. Border Area.
•	CIESIN will work with the participants in the Environmental Plan for the Mexican-
U.S. Border Area to develop and host a large interdisciplinary database of data sets
and related contextual information for the whole border area, including Mexico.
This database will allow investigators to easily access data for any part of the area,
across state and international boundaries.
•	The participants in the Environmental Plan for the Mexican-U.S. Border Area will
assist CIESIN in obtaining major policy documents, as well as other information, for
CIESIN to put on-line, and will assist with the identification of data resources.
The primary task in the out -years of the project is to find more data sets
relevant to the Environmental Plan for the Mexican-U.S. Border Area that can be
usefully harmonized and integrated so as to shed light on a health, land-use, or
industrial metabolism issue; conduct the harmonization and integration of the data;
and then analyze and archive the results. In the process there will be an effort to

identify and write directory entries for the major environmental-change related data
sets in the Mexican-U.S. border area.
Deliverables (Task 7):
Year one: Compendium of Data Custodians with brief descriptions of data held.
The Compendium will be published in both paper and electronic formats. Annual
updates.
Year two: Prototype Regional environmental Information system. Inventory of
waste disposal sites. Inventory of shared water resources.
Year three: Operational Regional Environmental Information System. Report on
environmental quality in the border area.

r -^MExecutive Summary
Executive	I oTexas, mostmajor state agendes and universities either have, or are in the process
Summarv	I acquiring. Geographic Information System (GIS) technology. Daily interaction
I between these state agencies and their federal counterparts would be greatly
¦ >wti if existing data were readily available and easily transferable in GIS
format Unfortunately, this is not the case. Hie majority of data now boused in state and
federal ngfyi** is not available in GIS format, and the small percentage of information
thai has been converted to GIS digital foonat has been prepared cm a project-by-prcject
frwrff. with little regard to future data transfer or sharing needs. The absence of national
or statewide GIS data standards has perpetuated this probkm.
Recent advancements in GIS technology have produced a unique tool capable of rapidly
nrrxttng large quantities of data, transforming the data into easily understood graphic
fanap»* and allowing its ™»iripniatv»n to illustrate existing or proposed conditions One
of the fundamental building blocks upop. which a successful CHS most be constructed is
the "data dictionary." The GIS Data Dictionary, as defined by the Texas Department of
Information Resources (DIR), provides a "description of the information contained in a
data coverage, e.g., format, definition, structure, and usage."
Recognizing a need to improve information exchange capabilities of state and federal
agencies in Texas, staff of the Texas General Land Office (GLO) and the U." S.
Environmental Protection Agency (EPA) Region 6 initiated a cooperative project under
the State/EPA Data Management (SEDM) Financial Assistance ftogram to assist with
the development and testing of a prototype GIS Data Dictionary.
Unknown to GLO and EPA collaborators, two other initiatives which would become
intimately linked with the project were under way. While discussions were being held
regarding development of a cooperative project, new state legislation was adopted
designating GLO as the lead agency in Texas for oil spill response and prevention. This
new mandate canied with it the need for frnm»diat» development of a comprehensive
statewide oil spill response and prevention program and the technical support necessary
to feHiitat* such a program. It was apparent from the outset of oil spill response planning
within the GLO that immense quantities of data from a variety of disciplines would be
required to meet the needs of the program. For this reason, a high priority was placed
upon acquiring state-of-the-art GIS capability for the Texas General Land Office Oil
Spill Prevention and Response ftogram (OSPRP) at the earliest possible opportunity.
Although a sense of urgency existed- to develop this new oil spQl GIS, planners within
GLO were aware from previous experience that (1) the most costly part of GIS
development is data acquisition, (2) the oil spill GIS would be a long-term commitment,
and data entered into the system would have to be useful for many years, and (3) most of
the data entered into the system would come from external sources. As these factors were
considered, GLO staff agreed that, regardless of the urgency, careM* planning was
needed to ensure that data acquired for die oil spill GIS was properly doaimcnted.
Without this documentation, little confidence could be placed upon the accuracy or
reliability of the data. The implementation of GIS data standards was recognized,
therefore, to be a critical component of the oQ spill GIS development.
During this same period, DIR, the Texas state agency charged with providing leadership
and coordination of information resource management within state government, created a
subcommittee of the Texas GIS Standards Committer, to develop comprehensive
standards and guidelines for GIS used in state governmental agencies and universities.
These standards and guidelines would promote higher levels of data compatibility
between state agencies, thereby facilitating easy transfer of GIS data between users and

saving state revenues. Within this standards development process, DIR created tbe Data
Dictionary Working Group (DDWG) to panne development of a gantlarrti7ed data
dictionary template.
GLO's urgent need for an oO tpUl CIS and tbe creation of tbe DDWG by DIR proved
fornritous for tbe EPA/GLO cooperative project. The Principal Investigators (Pis) were
able to closely coordinate tbe SEDM prqjea with both DIR's GIS standards
development activities and effects by Ibe OSPRP to develop an oil spfll GIS. Ibis
mnrrtinatin« ensured minimal duplication of effort and maximum utiliratioo of tbe
resources available to conduct tbe project.
Daring tbe first phase of tbe SEDM prefect, information was collected regarding tbe
status of GIS use fa Texas and otter EPA Region 6 states. Ibis fafonnatiaa provided an
overview of ongoing activities to develop GIS standards throughout tbe region. With the
information in band, and a draft data dictionary template developed in cooperation with
DIR's DDWG, a "Data Dictionary Workshop" was held in Austin in February 1992 to
explain tbe purpose of the SEDM project and id solicit public input and participation in
testing tbe template.
In tbe months that followed, more than 51 individuals representing 19 organizations
participated in 35 interagency and bra-agency meetings to test tbe template. Over 2,000
pages of documentation were compiled during this period of intense interagency
coordination and, as a result of public participation, several refinements of tbe template
were developed and incorporated.
A second workshop was held in July 1992 to review findings of the working groups.
Remarks from tbe participants resulted in additional minor modifications of the
template's format and content Comments during tbe workshop were very supportive of
both tbe testing methodology that had been used and tbe data dictionary template format
that was developed.
Tbe public workshops and "interagency working group" methodology created:
¦	an increased awareness of the need for GIS standards in Texas and EPA Region 6;
¦	a heightened regional awareness of ongoing GIS planning activities; 8nd
¦	a mechanism for many individuals and groups (who otherwise might not have
participated) to participate in development of state data management standards.
An ancillary benefit of die project has been an improved spirit of cooperation among the
individuals and organizations who participated. This broad spectrum of participation and
focus on a common goal helped to reduce tbe mind-set of isolationism with regard to
data ownership.
A significant amount of information regarding tbe location, format, and content of data
sets held by numerous state and federal agencies was compiled during execution of the
project. This information will be an invaluable starting point for future development of
state and regional GIS applications.
On August 17, 1992, the Texas GIS Planning Council reviewed and unanimously
accepted as a statewide GIS data standard the data dictionary trmplatf. developed, in part,
through tbe efforts of this project. Ibe GLO, by way of this report, recommends that the
data dictionary template be evaluated as a potential reporting requirement for future GIS
data submitted to EPA Region 6 by contractors or cooperating agencies. Consistency
with this data format would greatly facilitate the exchange of GIS data between state and
federal agencies in Texas and, it is hoped, throughout the region.

coastal Wetlands Habitat Monitoring in Texas

Historical inventories and trend analyses of coastal wetlands
have been poorly documented for Texas, perhaps moreso than any
other state with a similar magnitude of coastline. Since 1988, the
Texas Parks & Wildlife Dept., Resource Protection Division, has
pursued the objective of building a digital map database of coastal
-wetlands, associated habitats and land use for its resource
management and assessment programs. Bafeed on historical aerial
photography and digital remote sensing data, the wetlands database
would start in the mid 1970's, and achieve the accuracy of a
1:24000 map scale. The habitat classification Scheme adopted has
been developed by the N0AA CoastWatch Change Analysis Program and
comprises a hybrid system with the Cowardin U.S.F.W.S. National
Wetlands Inventory classification. This information will be
applicable to: habitat and land use inventories of the Texas
coastal zone; trend analysis of habitat changes over time; and
environmental impact assessment during regulatory reviews.
These goals present an enormous task for a mapping program
considering there are some 407 U.S.6.S. quads (7.5 min area) in
just the 18 coastal counties from Brownsville to east of Galveston
Bay. Such obvious program limitations have led to organizing the
scope of work into manageable phases based on priority of resource
information needs.
1)	Cartographic mapping of submerged vegetation has been
targeted for the entire Texas coast. Previous qualitative studies
have indicated that this coastal habitat is decreasing
dramatically. Recent quantitative mapping has been completed on
this habitat component for the San Antonio Bay System, Galveston
Bay System, and parts of the Corpus Christi-Nueces Bay System.
2)	In order to address specific resource management issues,
wetland habitat mapping and change analysis has been performed for
certain key sites or entire bays. This was recently done for one
of the TPWD Coastal Preserve management areas (Welder Point, a
Whooping Crane sanctuary)) and the Nueces Bay System as part of a
study to evaluate impacts of altered freshwater inflows from the
Nueces River. Wetlands have been compared over a ten year period
representing before and after the Choke Canyon Dam was built on the
Nueces River.
3)	Cooperative arrangements are being developed with federal
programs to complement ongoing, national mapping efforts. Recent
cooperation with the N0AA/CoastWatch CCAP Program has dealt with
a pilot project on the Galveston Bay region of Texas. Emergent

wetlands are being interpreted and classified from Landsat thematic
mapper imagery, and change analysis will be performed for habitat
features over the period from 1988 to 1992. Protocols and
methodology developed by the CoastWatch Mapping Program are being
applied in a pilot study to discriminate between the following
habitat classes: open saltwater; open freshwater; riverbeds;
saltmarsh (low and high); tidal flats; palustrine marsh; coastal
prairie; coastal uplands; and coastal land use in the adjacent
uplands (eg. -agriculture, native forest, urban, etc.). A subscene
test area in lower Galveston Bay (Chocolate-Christmas-West Bays),
equivalent to about four (4) 7.5 min quad sheets, is being
investigated by conducting detailed ground surveys and accuracy
assessment. Global Positioning Satellite technology is being used
to establish known geo-referenced ground locations.

2 BACKGROUND
2.1 TRACS Project
Over the past several years, a cumber of surveys and studies have
been conducted which related to the Information Management needs
of the Texas Water Commission (TWC). In an agency report.
Framework For the Future", published in December 19S7. an
Information Processing Task Force established by the Executive
Director documented its findings regarding information needs in the
agency. A very significant need expressed by a large percentage of
staff interviewed during the needs study was for a comprehensive,
integrated and flexible system to manage, analyze and generate
reports from the vast amounts of data and information collected and
used by agency staff. This need was included in the subsequent TWC
Strategic .Plan and the Long-Range Automated Information and
Telecommunications Systems (AITS) Plan.
In the AITS Plan, TWC proposed to address this need by designing a
new system, called the TWC Regulatory and Compliance System
(TRACS), that would replace scores' of existing systems. TRACS
would take advantage of the latest database design principles,
recent dramatic advances is hardware and software technologies,
and extensive involvement by" program area staff throughout the
development phase.
As discussions about TRACS continued, it became apparent that
some of the key requirements for improved information access were
geographic in nature. TWC manages and uses vast amounts of
information on paper maps, including environmental data and
locations of regulated entities. Recent advances in Geographic
Information System (GIS) technology have made .it practical to
process maps by computer. One of the most significant contributions
of TRACS would be to put TWC's maps on-line and to provide support
for management, analysis and viewing of map information. GIS has
thus been established as a key conceptual component of TRACS (see
figure 2-1).

A great number of federal, state and local agencies are working to
implement GIS technology, for reason very similar to TWC's.
However with TRACS, TWC has the rare opportunity to formally
introduce GIS technology in concert with the design and development
of a unified, agency-wide relational database management system
(RDBMS). TWC may be one of the first agencies to deploy the latest
in RDBMS and GIS technologies in a complementary mode from the
ground up. This concept directly supports the information access
needs expressed in Framework For the Future.
2.2 Prior Use of GIS at TWC
In the mid 1970*5, the Texas Department of Water Resources
assembled one of the first GIS systems operating at the state
government level. Most basic computer mapping functions were
supported, and over several years powerful spatial analysis
functions were added. This system is currently managed by TWC's
Data Processing Services section, and it still supports a small

4 CONFIGURATION
4.1 TRACS Configuration
TWC is in the process of procuring appropriate hardware and systems software
to develop and test TRACS, as well as to provide a platform for expansion of
hardware capabilities to support TRACS production. Figure 4-1 gives an
overview of the proposed architecture.
Major components of the initial TRACS configuration include:
TRACS Database Server (1) — ft>r bid
Application Servers (3) — Rs/uooo 550
R^CdCOO 70
Development Server (1) — fcfocoo 3zP
Development Workstations (20) — &5/&>ooo 32.0
f&CpOOO 32-© H-
Remote Office Workstations/Servers (3) — kz/ipooo 32o
PC Compatible Workstations (50) — 3&?/33
Network — NFS
Relational Database Software — XN 6&ES
TWC has placed a strong emphasis on adhering to the latest standaros for
hardware, software, data communications, data management, development
tools, and user interface in the TRACS Request For Quotation (RFQ)-.
Note that a subsequent procurement will be necessary to provide additional
hardware, software and network components needed to support an operational
TRACS system.

A2 GIS Hardware Configuration
The initial GIS hardware configuration should include components necessary to
implement a complete set of GIS toots and to build high priority TWC/GIS
applications. Additional stations and input/output devices will be procured as
required m the future to suppon increasing GIS utilization in the agency.
Figure 4-2 gives an overview of the proposed TWC/GIS configuration. A central
GIS database server will hold all standard graphic GIS data and manage
access by multiple users. A central raster data server will use a large capacity
optical 'jukebox" storage device to store all raster images used by the GiS. GIS
workgroups are distributed throughout the agency and connected to the central'
servers via an enhanced TWC network.
Each of TWC's program divisions has identified potential GIS applications.
Many of the larger field offices woufd also benefit from access to GIS. It is logical
and economical to provide GtS access at a workgroup level; that is. each
program division and larger field office would maintain a separate work area
where GIS workstations and peripheral equipment are located. The proposed
workgroup configuration is shown in Figure 4*3.
The number of stations could vary initially from 1 to 4, and some workgroups
may not require a page scanner, digitizer or plotter initially. The overall network
and GtS structure will be such that each workgroup can be incrementally
expanded to meet growing needs. The workgroup hardware need not be all
located in the same room.
The Administrative Services Division will be expected to support the agency's
GIS in a number of areas such as digitizing services, high Quality map
output/publishing, applications development, special projects, training, common
workstation access, database administration, and systems support. The
proposed initial hardware configuration for this division is shown in Figure 4-4.
... refer to need for the GIS configuration to fit into the general TRACS
configuration...
in its initial release, it is proposed that all GIS users work from a full workstation
platform. As TWC builds and refines aoplications using TRACS and GIS, It looks
promising that PC platforms may be utilized for some routine GIS tasks' '
Following are brief descriptions of the hardware components shown in Figures
4-2 through 4-4.
4.2.1 GIS Database Server (1)
A central, UNIX-based computer on which all agency-wide graphic GIS data will
reside. The server should run at 25 MIPS, have 32 MB of RAM, 20 GB of disk
storage, and the capability to expand disk storage to 50 GB in the future. Access

to the database server will be transparent to GIS users, via a workgroup server.
Since me database server will not be required to suppon individual users, it wili
be able to manage and provide access to GIS files much more efficiently than
otherwise possible.
4.Z2 Raster Data Server (1)
A central, UNIX-based computer that will specialize in handling graphic data
stored in raster form. Due to the large size of these files, optical "jukebox*
storage will be employed instead of conventional magnetic storage. Optical
storage is much more economical, but at some expense in access time. Two
types of raster data will be stored on this server. Geo-reterenced raster images
will compnse certain layers of the GIS, such as U.S. Geological Survey quads.
Non-georelerenced raster images are scanned documents, field inspector
sketches, etc that are logically associated with TWO regulated facilities and can
be accessed by both TRACS and GIS users. As with the GIS Database Server,
access to this server by users will be transparent via intermediate servers.
4^3 GIS Workgroup Server (12)
A UNIX computer running a complete GIS software package and capable of
supporting a number of workstation users over a network. X Windows software
will provide a common, graphic user interface tor all users. The server should
contain 24 MB of RAM to suppon 3 users, or 32 MB to support 5 to 7 users.. The
server should run at 25 MIPS and include 2 GB of disk storage.
4.2.4 GIS Workstations
Three levels of workstation are proposed tor GIS use. All three are expected to
fully access all functions of the GIS software package and will include nigh
resolution graphics; they will differ in processor power and flexibility. In

The GIS software package to be used by TWC must function in the
integrated TRACS environment. It oust be UNIX-based and support
all the open systems standards described in the TRACS Systems
Requirements document It must be a full-featured system, including
support for simultaneous raster/vector processing and three-
dimensional analysis, h must store attribute data in an external
INGRES relational database located on a remote server and support
full bi-directional access between the two platforms. The user
interface must be easy to use and it must allow direct access by
end-users to all GIS functions. It must provide the means to
maintain database security and integrity.
Section 2.4.1 describes the vendor evaluation study conducted by the
GIS Design Team. The design team feels that at least four vendors
offer GIS solutions that meet TWC's requirements. TWC should
complete the GIS software selection process in early calendar 1991.

PREFACE
The focus of this assessment is surface water quality and the
identification of potential sources that influence water quality.
He have given only mention to ground water resources, solid waste
management, and human health risk in this year's assessment.
The Texas Clean Rivers Act, SB 818, calls for an ongoing
regional assessment process. This offers the opportunity for
investigating the sources and impacts of additional pollution
sources. Information on Mexican water quality and pollution
loading from tributaries is largely unavailable at this time. We
have made a request through the XBWC for ambient water quality
monitoring data from Mexico. Zt is al6o possible that estimates of
pollution loading from wastewater and air emissions in Mexican-
cities and factories can be inferred from industrial activity and
land use as this information becomes available.
There is considerable concern about the effects the pending
North American Free Trade Agreement (NAFTA) would have on air and
water quality along the U.S.-Mexico border. Several other studies
are under way, each focusing on environmental conditions likely to
be aggravated by NAFTA. The Texas Department of Health recently
completed an investigation of possible causes of neural tube
defects in the Lower Rio Grande Valley. The Texas Water
Commission, with the IBWC, USEPA, Texas Department of Health, and
Texas Parks and Wildlife Department, will be conducting a toxicity
survey of the entire Rio Grande in Texas this autumn. The U.S.
Bureau of Reclamation is conducting a study of water resources in
and along the Rio Grande. The U.S. Fish and Wildlife Service is
conducting an assessment of toxic impacts on the Atascosa Wildlife
Refuge along the Arroyo Colorado. The U.S. EPA is planning a
multi-media environmental monitoring and risk assessment in the
Brovnsville-Matamoros area. Our goal is to have this assessment
contribute significantly to our understanding of present
environmental conditions in the Basin.

INTRODUCTION
Directive and Purpose of this Assessment
The Texas Clean Rivers Act, Senate Bill 818, 72nd
Legislature, 1991 (SB 818), requires that the Texas Water
Commission implement a regional vater quality assessment program.
The Commission has.determined that the assessment program for the
Rio Grande Basin would best be accomplished by using designated
funds to prepare a report in-house and carry* on other activities
described in Sections 320.1-320.9 of the Texas Water Commission
Permanent Rules. The staff-of the Standards and Assessments
Division will coordinate this task. This is the first of the
biannual assessments and addresses the elements specified in
these rules (6ee Appendices 1 and 2 for SB 818 and related TWC
rules).
The assessment report documents the extent and causes of
vater quality impacts using existing data. Response to vater
quality concerns will be developed by the ongoing biannual vater
quality assessment program as .mandated by SB 818. These vill
include identifying additional information needs' and suggesting
how these needs can be met, and proposing specific actions by
entities with regulatory authority.
Entities and Participating Agencies
This assessment report has been prepared with the
participation of representatives from state agencies, political
subdivisions, and other governmental bodies and individuals or
entities with an expressed interest in water quality matters in
the watershed. These members represent a diversity of interests.
In order to encourage public participation at all levels, there
vill be two tiers of committees for the Rio Grande River Basin:
one Oversight "Committee which will meet in Austin five or six
times over the next several years, and various Local Committees
which will meet with similar frequency in the border towns of £1
Paso, Laredo or Del Rio, and Brownsville or McAllen to discuss
regional concerns.
The Oversight Committee serves an advisory role. The
members vill help identify vater quality issues which are
significant to the watershed. Additionally, the agencies and
organizations which have representatives on the committee will
provide any relevant water quality data to the Water Commission
for use in the basin assessments.
The first of the Oversight Committee meetings was held in
Austin on August 19, 1992. The members of the Rio Grande River
Basin Oversight Steering Committee are as follows:
TWC: Barbara Britton, John Hinojosa, Laura Koesters, James
Kowis, Hector Villa, and Kendall Moss
Governor's Office: Frank Fuller, Andrea Abel

Regional Steering Committee meetings will be held this
autumn in these regions of the Basin: El Paso-Presidio; the
Middle Rio Grande; and the Lower Rio Grande Valley .from Falcon
Dan to the Gulf. The first of these meetings will be primarily
informational—to introduce the objectives of the assessment and
mechanism for local involvement. The meetings are scheduled for
El Paso on September 22nd and Laredo on September 25th. State
and local officials, environmental groups, university
representatives, and their Mexican counterparts will be invited
from throughout the Basin. A similar meeting has already been
held for the Lower Rio Grande by the Lower Rio Grande Valley
Development Council.
Geographic Poena of Xaaeaament
From the headwaters in Colorado in the Rocky Mountains, the
Rio Grande (or Rio Bravo in Mexico) flows 3100 kilometers (km) to
the Gulf of Mexico, first passing south through New Mexico. The
Rio Grande enters Texas some twenty miles north of El Paso and
forms the border between Texas and Mexico as it flows from El
Paso to the Gulf of Mexico. The Rio Grande Watershed drains an
area of 355,500 square miles in Colorado, New Mexico, Texas, and
Mexico, of which about 88,968 square miles in the United States
and 87,365 square miles in Mexico contribute streamflow to the . £
Rio Grande; the remaining area drains internal basins (Eaton'S"
1987). The Rio Grande Basin is depicted in Figure 1 ^"""Principal
tributaries in Texas are the Pecos River and the Devils River,
and in Mexico the Rio Conchos, the Rio Salado, and the Rio San
Juan.
The international nature of the Rio Grande River complicates
a water quality study of the Rio Grande. Major tributaries drain
into the Rio Grande from Mexico; the Rio Conchos provides most of
the flow of the Rio Grande below Presidio. The lack of water
quality data in the Mexican portions of the Rio Grande Basin make
it difficult to make a thorough assessment of water quality

-------
impacts in the Basin. This assessment describes the watershed
within Texas. Although some of the elements will consider
Mexican influences on the water quality, this report will largely
consider only the watershed within Texas. As information becomes
available, it will be integrated into the ongoing biannual
regional assessment program. A major aspect of future
information gathering will focus on joint U.S.-Mexico agreements
for data-sharing and monitoring.
Geography and Climate
The water quality in the Rio Grande Watershed, like all
watersheds, is defined by the geography and climate within the
watershed. The river originates in the Rocky Mountains of
southern Colorado at an elevation of 12,000 feet. It then flows
south from Colorado through New Mexico for 600 miles, in a
"shallow valley about 250-500 feet below the high desert plains
of the area." (Schmandt and Hard, 1991). The river enters Texas
at an elevation of 3800 feet. About 100 miles south of £1 Paso
the river cuts through a plateau, forming deep canyons and
gorges. After flowing through thia area for about 480 mileB, the
final 680 miles of the Rio Grande flows through plains. The
geography of the Rio Grande Basin within the study area can be
classified as tropical or subtropical desert (Eaton and Anderson,
1991).
The northern portion of the Basin in Texas is mostly desert,
but the climate becomes less arid and more tropical as the river
flows south. In general, the region is hot, warm and windy
(Schmandt and Hard, 1991). The Basin averages more 100* F days
than any other part of Texas for the months of May through
September (Bomar, 1983). Temperatures are higher in the southern
basin than in the northern basin, on the whole.
The northern basin has less precipitation than the southern
basin. For example, average rainfall ranges from 7.82 inches at
El Paso to 12.21 inches at Fort Stockton in the upper and middle
portions of the basin, respectively, to 20.14 inches at Laredo
and 25.44 inches at Brownsville in the southern portion (Bomar,
1983). The Rio Conchos and the Rio Grande receive flow from
snowmelt, but below El Paso most water in the river comes from
thunderstorms and hurricanes (Schmandt and Hard, 1991).
Regional
Texas is a large state with many distinct natural land forms
and vegetational areas. Streams that traverse these natural
areas tend to be just as distinct since water flowing over and
through the land to stream channels acquires and integrates
characteristics from the soils and vegetation (Hynes, 1970).
Omernik (1987) developed an ecoregion map of the conterminous
United States based on perceived patterns in a combination of
3
USEPA Office of Water (WH-547). US-Mexico Border GtS Catalog attachment July 1993.
Page 235
-------
factors. These factors included land surface form, land use,
soil types and potential natural vegetation. The nap is intended
to provide a geographic framework for resource managers to
determine attainable ranges of chemical quality, biotic
assemblages, and trophic states of aquatic ecosystems. Omemik
and Gallant (19B7) developed larger scale regional maps which
delineate most typical areas within each ecoregion. Figure 2
depicts the-12 Texas ecoregions as extracted (and reduced) from
the regional map.
The TWC has undertaken an ambitious project to determine the
physical, chemical and Biological characteristics of selected
streams within the ecoregions in order to establish appropriate
uses and water quality criteria for the various areas .of the
state. This project is also intended to provide information
necessary to develop biocriteria and to establish least disturbed
reference streams which can'provide a bench mark for determining
attainable ranges of chemical quality and biotic assemblages.
(Tvidwell and Davis, 1989; Bayerr et al., 1992). The basic
premise is that stream water quality and biotic assemblages
within ecoregions should fee similar since the acquired water
quality characteristics are derived from similar watershed
components within each ecoregion. The information from a few
streams can then be reasonably extrapolated to other streams
within the ecoregion.
Five of the 12 Texas ecoregions are contained wholly or
partially within the Rio Grande Basin (Figure 2). Table l
contains the combination of physical features that were used to
delineate each ecoregion within the basin. Ecoregion 23 -
Arizona/New Mexico Mountains is only represented in Texas by. the
Guadalupe Mountains in a relatively small area of the basin along
the Texas/New Mexico border. Ecoregion 24 - Southern Deserts is
also wholly contained within the basin and represents the vast
majority of the drainage area of the Rio Grande in Texas. This
ecoregion encompasses the area commonly known as the Trans-Pecos
region of Texas, although the ecoregion boundary extends to the
east of the Pecos River from the border with New Mexico down to
the vicinity of Del Rio. Ecoregion 25 - Western High Plains
occupies a relatively narrow band of the basin from the New
Mexico border in Loving County southeastward to the northern
portion of Crockett County. Ecoregion 30 - Central Texas Plateau
occupies a small portion of the basin from the southwestern
portion of Schleicher County southward along the western border
of Sutton County, then south along the eastern border of Val
Verde County to near Del Rio, then southeast to Brackettville.
The remainder of the basin southeast of Del Rio is located in
Ecoregion 31 - Southern Texas Plains.
Eight streams located within the Rio Grande Basin were
sampled for the TWC ecoregion project (Bayer, et al., 1992), four
each in Ecoregions 24 and 31. Because of the arid conditions in
this part of the state, it is not surprising that documented
springs provided base flow in the majority of the streams.
The sampled ecoregion streams and the classified segmented

waters comprise almost all of the perennial waters within the
basin. Other streams that are known and nay possibly be
perennial include Terlingua Creek in Brewster County which flows
into Segment 2306 - Rio Grande Above Ami6tad Reservoir, Cifenegas
Creek in Val Verde County which flows into Segment 2304 - Rio
Grande Below Amistad Reservoir, and Elm Creek in Maverick County
which flows into Segment 2304 - Rio Grande Below Amistad
Reservoir. TWC monitoring stations are located on Terlingua
Creek and Elm Creek and Cilnegas Creek has been sampled and
assessed by the TWC in response to a waste discharge permit
action.
Ci£negas Creek is located on the western edge of the City of
Del Rio and base flow is provided by Ci6nega Spring. A five per
cent cumulative probability flow of 10.2 cfs was calculated from
data provided by an IBWC gaging station below the spring. Based
on physicochemical, benthic macroinvertebrate and fish data, the
TWC has assigned high quality aquatic life uses to the stream
from the confluence with the Rio Grande to the headwater spring
source.
Brief descriptions of each sampled stream modified from
Bayer, et al. (1992) is included in the segment-specific
discussion in this report. Complete listings of benthic
macroinvertebrates, abundances and calculated metrics and fish
species assemblages are included in the report by Bayer, et al.
(1992) for each of the streams sampled.
Socioeconomic Characteristics cf the Baain
The Rio Grande Basin is an international basin with people
living in the United States and Mexico. The study area, the Rio
Grande Basin in Texas, is one of the poorest regions in the
United States. The counties in the Lower Rio Grande Valley are
the poorest in the U.S. The per capita income in 1989 for Texas
was 12,904 dollars, while for the counties in the Basin it ranged
from a low of 5,386 dollars in Dimmit County to a high of 12,482
dollars in Loving County (Bureau of the Census, 1992).
Another measure of poverty is the percentage of all families
with incomes below poverty level. For the 6tate of Texas, this
figure is 14.1 percent. Excluding Loving County (1990 population
107), which had no families below the poverty line, families with
incomes below poverty level ranged from 9.1 percent in Reeve.s
County to 56.5 percent for Starr County. However, many of the
Rio Grande counties have numbers for this index in the 30 to 40
percent range. For example, Hudspeth, Edwards, Hebb, Jim Hogg,
Zapata, Presidio, Ector, and Maverick Counties all had a third
or more of their families living below the poverty line. For El
Paso, the largest metropolitan area in the Basin, the figure is
22.4 percent. A total of 25 of the 31 counties in the Basin have
poverty rates greater than the statewide rate.
The population of the Rio Grande Basin in Texas, excluding
the portion nearest the mainstem in Hidalgo and Cameron Counties,

was estimated at 943,778 for 1990 (TWDB, 1990). Of this amount,
the majority, or 591,610, lived in El Paso County. Webb, Val
Verde, Starr, and Pecos counties followed in population size with
131,833, 38,721, 38,548, and 36,037 people, respectively.
Between them, these five counties accounted for 836,749 people,
or 88.7 percent of the Basin's population. The largest city was
£1 Paso, with 515,342 residents. Laredo is the second largest
city in the study area, with 122,899 people. Most of the major
population centers are located on the Rio Grande, with a -few
located on the Pecos. In northern Mexico, Ciudad Ju&res is the
second largest city after Monterrey.	_
Population projections for the Texas part of the tiasin,
using the high series of the Texas Water Development Board—which
bases population estimates on high growth rates of the past
twenty years—detail a tremendous growth in population.
Including the cities of McAllen and Brownsville, the population
of the Rio Grande Basin, estimated at 1,337,492 in 1990, should
increase to 1,577,014 by 2000 and 2,440,211 by 2030 (Texas Water
Development Board, 1989}. Doubling of basin population should
occur within fifty years of 1990, with many border cities
doubling in population even sooner.

INTEGRATED INFORMATION SYSTEM
INITIAL GIS APPLICATIONS
APPLICATION:
BACKGROUND: DRASTIC napping is currently carried out manually.
Maps are produced by collecting data, transfering information
for each layer onto mylar film/ and creating a final DRASTIC
nap by overlaying the layers. The current process is slow and
time consuming. It is estimated that at the current rate of
approximately 5 to 7 county maps per year, the project will
take nearly 50 years to complete. Many population centers in
Texas are in desperate need of the information carried 'in the
DRASTIC maps, but manual production limitations prohibit
creation of maps for these areas. It is estimated that fully
automating the process through a GIS should increase
production to perhaps four maps per month, resulting in a
completion of the project in ten years or less.
BENEFITS:
REFERENCES:
GIS SUPPORT NEEDED:
*	PHASE 1: Current (FY92) needs to support DRASTIC
include digitizing data layers, integrating data sets;
calculation of the DRASTIC indices (modeling); and providing
access to other users of the DRASTIC maps in the agency and
throughout the state.
*	FUTURE: It is envisioned that the DRASTIC maps will
become part of an interactive model: a vulnerability or
suitability tool for others at the TWC to use in specific
programs that evaluate ground water pollution potential.
Support for other users through software such as ARC/VISW will
be required to make DRASTIC an accessible tool for decision-
making at the TWC.
TARGET DATE:
H/S REQUIREMENTS:
*	DEVELOPMENT PLATFORM: The basic requirements include the
RS-6000 workstation (currently at the SFA Building) and
peripherals (currently located at Shoal Creek), linked
together; and the appropriate software (UNIX, Geovision, and
ARC/INFO) installed for evaluation.
*	INITIAL PRODUCTION PLATFORM:
STAFF REQUIREMENTS: Phase 1 requirements (in FTE's) are envisioned
as 1.5 Ground Water Section staff, 0.5 GIS staff (from the GW
section), and 1 admin, production staff. This is a very rough

Training - ARC/INTO training (5 day intro class) has been
completed by Margaret Hart. She is also scheduled for an
intro UNIX class taught by TWDB for next month. Further
training in UNIX and GeoVision is required for completion"
of this task.
Evaluation of software
Development of application package/process - a DRASTIC
application package exists already in arc/INFO. The
application needs to be evaluated and perhaps modified to
suit the needs of the project et TWC.
Evaluation of data availability - a search for most of
the available data layers has been carried out by Bob
Blodgett. The data sets still need to be evaluated to
determine applicability to the DRASTIC mapping program.
Data collection and digitizing - data sets must be
collected (free or purchased) and non digital data roust
be digitized before it is useful for the project.
Pilot project map production - it is hoped that a
prototype DRASTIC map will be produced by end of FY 92.

SENATE BILL 818 Summary Report
I. INTRODUCTION
Texas. The name evokes thoughts of varying landscapes-vast, open spaces and
vibrant, bustling metroplexes, sub-tropical and desert climates, rolling hill
country, imposing cliffs and sweeping lowlands. The waters of Texas are equally
diverse, from the salt waters of the Gulf of Mexico, to pristine fresh waters; the
twisting bayous of the southeast, to the parched, intermittent streams in the west.
This diversity is both desirable and challenging, for with each of these waiers
comes specific, varying demands. These waters are critically needed to provide
recreation, nourishment, irrigation, transportation, and economic growth. Yet.
Texas waters face adversity daily: threats from contaminated wastewater
discharges, contamination from nonpoint source pollution, overloading of
nutrients, intrusion of toxic materials, stresses on water supply, increased
sedimentation, excessive aquatic vegetation and destruction of habitat.
A. Summary of the Texas Clean Rivers Act of 1991
Texas watersheds serve more than 16.5 million people, and the state population is
expected to expand in the next 50 years to 30-35 million. Current demand for
waier is 75% of existing capacity. We expect thai, even with conservation
efforts, waier demands in the stats will eventually exceed existing water supplies.
Clean useable water is, and will continue to be, a priority for our state.
Therefore, it is imperative that the limited supplies of water we do have remain
unpolluted and available for drinking, recreation, and economic development.
Assessment and planning for the management of the diverse set of water quality
issues the State faces has proven difficult, for each river basin experiences its own
specific set of circumstances. While the existing water quality program effectively
addresses wastewater discharges fr6m municipal and industrial point sources,
many additional water quality issues remain and are in need of attention. The
State's current program does not adequately address nonpoint source pollution,

-------
routinely monitor and model for toxic materials and nutrients, routinely assess the
impacts of water quality and water supply simultaneously, or assess the cumulative
water quality impacts on human health, regional ecosystems, aquatic life, critical
habitats and wetlands.
Concerned with the historically fragmented approach to management of water
quality and quantity issues, the 72nd legislature passed the Texas Gean Rivers Act
(SB818), an approach to water quality planning on a watershed basis . The act
requires that each river basin in the State be assessed individually, and reports be
provided to the Texas Water Commission (TWC) every even numbered year. The
commission is directed to compile a summary of these reports to the Governor,
Lieutenant Governor and the Speaker of the House of Representatives by
December 1 of each even numbered year.
In creating and mandating a new, integrated approach to water quality
management, SB818 details some specific guidance in accomplishing the water
quality assessments, namely:
Comprehensively assess water quality on a watershed basis with
special emphasis on assessment of nonpoint source pollution,
nutrients ana toxi: maisriais.
Deief.iT* responsibility for water quality assessments to river

~r:u£T.	o: "ver basis steering ccrricees.
Permit on a dasm-wide basis to trie extent possible.
Fund for assessment through fees charged to wastewater and water
rights permittees.
Through this new approach, we can assess the ability of a river system, from
headwaters to the coast, to absorb and support the results of human activity.

-------
Rather than making broad generalizations about the entire state, it allows us to
address a diversity of issues pertaining to smaller geographic regions, to account
for differences between regions, and to assess cumulative pollutant impacts
throughout watersheds. Land, water, and coasts are treated as a single functional
unit with interlocking terrestrial, aquatic and marine ecosystems. Assessments
conducted under (he SB818 program will form the basis for a comprehensive
approach to water resource management that will enable the commissionrto
establish risk-based priorities to address under-Chapter 26 of the Texas Water
Code and under the federal Clean Water Act.
Tnis report marks the first summary of the assessments performed under SB818.
It reflects some of the complex and interrelated technical and social issues which
combined to require a new approach to water quality management in the State. It
details the limitations brought about by the unsystematic and single-objective
programs which have historically been the management strategy for the State.

THE TEXAS NATURAL RESOURCES INFORMATION SYSTEM
Introduction
The Texas Natural Resources Information System (TNRIS) Is the State's clearinghouse (or natural resource*,
data. Its primary purpose is to make data available to data users quickly and reliably. TNRIS was originally
established by the legislature in 1968 as the Texas Water Oriented Data Bank. In 1972, after four years ol
growth and diversification, it was designated the Texas Natural Resources Information System. In a more
recent legislative mandate, Senate Bill 325 of the 70th Texas State Legislature refers to TNRIS as 'a
centralized information system incorporating all Texas natural resource data, socioeconomic data related
to natural resources, or indexes related to data that are collected by state agencies or other entitles.*
TNRIS Is an operational unit of the Texas Water Development Board and for all administrative and managerial
purposes It is a part of that agency, its policies and guidelines, however, are set by an Interagency task
force composed of representatives from t5 of the State's natural resource agencies. Funding for TNRIS Is
provided by the State Legislature through the Water Development Board. A seven-member staff, known as
TNRIS Systems Central, conducts the day-to-day activities of the System handling requests for data and
implementing new capabilities to support the participating State agencies. The staff Includes individuals
trained In the natural and computer sciences. TNRIS supplies data to government, academia, and the
private sector. Systems Central offices are located on the fourth floor of the Stephen F. Austin State Office
Buflding, 1700 North Congress Avenue in Austin.
Data InventoriesrData Library
Through the years, the TNRIS staff has conducted inventories of computerized and non-automated natural
resource data housed in Texas State agencies. These inventories have been compiled into the TNRIS File
Description Report which describes over350 individual data files, inventories of aerial photography and map
holdings of private companies, universities, libraries, and other entitles have been an important part of this
activity. The staff indexes the data into TNRIS for use in supporting user requests. The Indexes refer users
to data which is housed in other agencies as well as to data files available in-house. Over 50 of th»
computerized files are available through a remote terminal access system.
Tvpea of Data end Other Services
In addition to providing Information about data availabBlty, TNRIS maintains a library of data which can be
accessed directly. For example, the System has a lending library of remotely sensed data which Indudes
aeriai photography and satellite Imagery of the entire State. TNRIS also serves as a distribution center for
U.S. Geological Survey maps (for government titties only) and has numerous other map collections
available for In-house use or reproduction. Computerized fBes available through TNRIS pertain to water
resources,"meteorology, biological resources, geotogy, and Census data.
TNRIS fills a number of additional roles such as serving as Geographic Names Coordinator for the State,
providing staff support for the Texas Mapping Advisory Committee, offering technical support for Slate
agency projects, and sponsoring symposia and workshops, in addition, TNRIS operates a geographic
information system, primarily for support of participating agency mapping requirements. The core of the
System's responsibflities, however, is data inventory, indexing, and retrieval.

GEOGRAPHIC INFORMATION SYSTEM DEVELOPMENT:
ROLE FOR TNRIS
CUSTODIAN AND SUPPLIER OF DIGITAL DATA BASES
TNRIS is a custodian and supplier of digital data bases in the same manner that it maintains and
supplies other natural resource information. It indexes and keeps a catalog of public and private
geographic files that can be read by mapping and CIS software. This catalog, which is a
specialized version of the TNRIS File Description Report, includes: the name of the organization
providing the data base; a description of the graphic and nongraphic data types; a description of
the geographic area covered by the data base; information about the data sources and scales used
in creating the data base; size of files and format of data storage; availability of files and type of
media for transfer; and name of contact person and telephone number.
TNRIS keeps and distributes copies of some public files. These are limited to data bases that are
static or come from public organizations which are not able or prefer not to handle requests for
their files. TNRIS'i ability to distribute digital data of this kind is restricted by the availability of
tape drives and storage area for tape archives.
CIS EDUCATION COORDINATION
The TNRIS staff organizes and coordinates workshops, seminars, and conferences related to
geographic information systems. This is done in response to requests and expressions of interest
from system users, and with the recommendation of the Remote Sensing and Cartographic
Committee (RSCC) and approval of the TNRIS Task Force.
FILE INTERCHANGE SOFTWARE COORDINATION
Convening files and whole data bases from one format to another for use on various mapping
and CIS systems is complicated by the many different data storage formats available. To facilitate
file conversion TNRIS provides the following information to users whenever possible: data
storage formats; availability of public domain and commercial file con**~rsion software; and
names of private-sector firms that provide file conversion services.
TNRIS distributes some public domain conversion software and offers staff expertise gained
through experience in convening files. TNRIS provides limited file conversion service, usually
restricted to the kinds of geographic files that it supplies or are used on its CIS system.
COORDINATION OF GIS ACTIVITIES AMONG PARTICIPATING AGENCIES
The TNRIS staff keeps abreast of participating agency activities involving projects of mutual
interest and ihe possible purchase of CIS hardware, software, or data. Staff are aware of
opportunities for coordination among the agencies in these efforts.
Some examples of coordination of GIS activiues are: arranging the demonstration of hardware,
software, or data of mutual interest; coordinating joint purchase or licensing of hardware,
software, or data where multiple-purchase discounts apply; and tracking present and planned
digiuzing efforts bv agencies to encourage cooperative efforts.

GENERAL INFORMATION ABOUT CIS
TNRIS staff are developing the expertise to answer queries from various users about CIS systems
and data. These questions range from basic information to very specific technical issues
concerning hardware, CIS software, and data bases. Staff can give information about products
known to them and provide addresses and phone numbers of suppliers.
CIS SUPPORT FOR PARTICIPATING AGENCY PILOT PROJECTS
If an agency participating in TNRIS wants to evaluate the potential of CIS for some particular
problem. TNRIS may provide CIS support for a pilot project involving a small portion of the area
in question. If the pilot project results look promising, the participating agency can apply the
technique to the enure area of interest by contracting with a commercial vendor or by developing
an in-house capability. Pilot projects are undertaken only after approval by the Task Force and
are generally reviewed and recommended by the RSCC before Task Force consideration.
FACILITIES AND TECHNICAL SUPPORT FOR SMALLGIS PROJECTS
It is the objective of TNRIS to provide the necessary training and support so that, whenever
possible, users can do their own CIS projects. These projects ordinarily use dau supplied by the
agency or data that are on-hand at TNRIS; staff do not generate dau through fieldwork. TNRIS
policies on equipment use by participating agencies and charges for use may limit the scope and
size of projects that can be undertaken.
LARGE CIS PROJECTS WITH PARTICIPATING AGENCIES
TNRIS may acuvely take part in large CIS projects that require significant effort by TNRIS staff
members. TNRIS participation in these types of projects shall generally require the following
conditions: the project must have significant benefits for a participadng agency and its mission
for the state; the project must have direct benefits for TNRIS; there must be a clear statement of
the reason TNRIS is uniquely suited to contribute to the project; and, in most instances. TNRIS
must receive significant financial assistance for additional personnel and expenses so that
dedicauon ot staff and facilities to the project does not adversely affect the other functions of the
organization. Large CIS projects are undertaken only after approval by the Task Force and are
generally reviewed and recommended by the RSCC before Task Force consideration.
1990 CENSUS MAPPING AND STATISTICS
Government agencies already are frequent users of existing automated and tabular Census
information. The 1990 Census has a major emphasis on'computer mapping; the union of CIS
technology and Census statistics makes the supply of Census informadon in a graphic form a very
important task for TNRIS. The CIS software (ARC/INFO) purchased by TNRIS is well suited for
the analysis and display of Census data. When Census information becomes available in map
format. TNRIS will be prepared to supply the information with the hardware and software that
has been acquired and the expertise that is being developed by its staff.

Before requesting data from either the catalog or the bulletin board check to sae that
your software can work with the available data formats and that you have sufficient storage
and data processing capacity to work with the flies.
It is also Important that you have an understandng of basic mapping concepts such as
map scale, map accuracy, and map projections. When overlaying maps of different scales
and accuracies it Is critical to remember that the resulting map will be only aa accurate as
the least accurate initial map. Also, when overlaying maps be sure that the mapa are in the
same geographic projection.
This catalog provides some background information about each file. For each file that
you select be sura that you understand its appropriateness for your spacHIc needs.

PREFACE
'The following proposal for an environmental atlas for a -portion of the" United
States-Mexico Border Area was prepared by the Bureau of Economic Geology
in the summer of 1992 and submitted to the U.S. Environmental-Protection
Agency, Region 6, in August 1992. Since then we have discussed the proposed
environmental atlas with additional potential users, and several events have
transpired that require minor changes in this document. SEDUE. for example,
has evolved into SEDESOL, and the North American Free Trade Agreement
has been signed. In addition, the Texas Water Development Board, through the
Texas Natural Resources Information System (TNRIS), has submitted a
proposal to Region 6 that complements this proposal and enables TNRIS to be
a state clearinghouse for data pertaining to the Texas-Mexico border.
More substantive additions should also be made. For example, Region 6 has
suggested that any project of this kind be expanded to include both the Texas
and the New Mexico segments of the United States-Mexico border.
Furthermore, although the emphasis of the current proposal is on sister city
pairs along the Rio Grande, a revision would expand the scope to include a
major effort of data compilation and analysis at a more regional scale. This is
needed to address those features, such as regional aquifers or major
watersheds, that extend beyond the 100-km-wide swath that defines the Border
Area, and to benchmark data sets or parameters that have regional impacts.
In short, this foundation document illustrates the parameters to be addressed
and the methodologies to be employed by the Bureau of Economic Geology in
compiling an environmental atlas of the Border Area. It can be readily modified
to accommodate changes in the scope of work as may be determined to be
appropriate during discussions regarding this important environmental initiative.

PROPOSED ENVIRONMENTAL ATLAS OF THE
RIO GRANDE/RIO BRAVO BORDER AREA
I. Executive Summary
Concern by the United States and Mexico over the environment of the border region,
manifested in 1983 by the bilateral Border Environmental Agreement, has been given
added impetus by the ongoing negotiations of the North American Free Trade
Agreement (NAFTA). Pursuant to the 1983 Agreement, an "Integrated Environmental
Plan for the Mexican-U.S. Border Area (First Stage 1992-1994)" (the Border
Environmental Plan or "BEP") was issued February 25, 1992, which describes
measures to be taken on both sides of the border to clean up existing problems and
prevent or reduce future environmental degradation.
The BEP is designed to solve environmental problems in the Border Area, which is
defined as a 100-km-wide area on either side of the 2,000-mile (3,200-km)
international boundary. For nearly 1,200 miles (1,920 km) of its total length, the
Border Area corridor forms a sinuous swath from El Paso/Ciudad Juarez to the Gulf of
Mexico with the Rio Grande/Rfo Bravo at its center. This portion of the Border Area is
the subject of this proposal by the Bureau of Economic Geology.
Focus on the Rio Grande/Rfo Bravo and the land and environment extending 100 km
on each side is appropriate, for it is the site of concentrated industrial, agricultural, and
urban activity. Moreover, substantial growth is projected for this area independent of
NAFTA, and this agreement could lead to a substantial acceleration of activity. With
development comes added population density and ever-increasing demands for clean
air, land, potable water, and energy. Careful planning is needed to meet these
challenges. Otherwise, the current struggle to deal with today's environmental
problems may be only an initial skirmish compared to the effort and cost of combating
problems that will occur if industrial development and the predicted doubling or more
of the border population occurs over the next few decades.
Border environments! initiatives—whether for remediation or long-term protection—
will be critically dependent on sound data, clearly and accurately analyzed. We
propose to develop an Environmental Atlas of the Rio Grande/Rfo Bravo
Border Area that responds to these informational and analytical needs.
The Atlas will address the water, land, and natural resources of the Rio Grande/Rio
Bravo Border Area, providing planners, policy makers, and developers with
information and data they need to wisely assess and guide development. The Atlas
will have a variety of uses and users. A major product of this work will be data bases
forming an environmental baseline of the Rio Grande/Rfo Bravo Border Area, which
will enable regulators and others to assess the impact of development over time. The
Atlas will serve both as a data base for land use planning and as a convenient tool for
portraying information on the environmental status of the land, air, and water. In
addition, it will support policy development and analysis and prioritization of
enforcement activities, and it will be a valuable resource for environmental education.
It should also serve as a focus for technology transfer between EPA and Secretaria de

Desarrollo y Ecologia (SEDUE) as well as provide an opportunity for technical training
of Mexican scientists interested in environmental studies.
In short, our goal is to produce a product usable by environmental regulators and land-
use planners at all levels of government, as well as industry. The Atlas will provide
vital data compilations and analyses of environmental parameters critical to resolving
ground-water and surface-water issues, solid and hazardous waste siting, industrial
siting, infrastructure enlargement, e. g., sanitation facilities, roads and bridges (both for
sources of construction materials, such as sand, gravel, and limestone, as well as
impact assessment), and creation of refuges, parks, and recreational areas.
Preparation of the Atlas will entail compiling a substantial amount of environmental
data. We will compile the best existing data on the quality and quantity of ground-water
and surface-water resources, energy resources (oil, gas, lignite, coal, geothermal),
and mineral resources. The Atlas will delineate regional ground-water flow systems,
water quality, recharge areas, discharge areas, drainage basins, wetlands, and
floodplains. The distribution of bedrock units and sediments or soils will be subdivided
according to their engineering characteristics. Features of special interest that are
common only to portions of the Rio Grande/Rfo Bravo region (e.g., earthquake-induced
faulting, caves and collapse features, landslides, expansive soils, active coastal
processes or erosion) will also be portrayed. In sum, all characteristics and attributes
that may be important indicators or constraints on where and how the border region
can be responsibly developed or that are part of environmental monitoring will be
compiled in the Atlas.
The Atlas will be produced in both digital and hard-copy formats. The digital
Geographic Information System (GIS) presentation facilitates ready addition and
updating of information and will enable users to select and display parameters of
particular importance to their special interests. The maps, which form the core of the
Atlas, will be accompanied by an interpretive text and relevant data tabulations that
analyze and explain the various environmental parameters. For example, a full
understanding of ground-water systems is critically important to those attempting to
remediate existing problems and to those attempting to prevent future degradation and
ensure potable water supplies. Under our approach, maps o* hydrologic parameters
will be interpreted so that users understand prevalent flow rates and directions, the
significance of the water-quality patterns, and the locations of recharge areas.
Compilation of existing data will allow recognition of those areas where additional
data points or refinements of existing information can significantly add to the reliability
and utility of the product.
In compiling the Atlas, priority will be given to those areas where the pressures of
development are the most intense: the sister cities of Ciudad Juarez-El Paso, Ciudad
Acufla-Del Rio, Piedras Negras-Eagle Pass, Nuevo Laredo-Laredo, and Reynosa-
McAllen and Matamoros-Brownsville in the Lower Rio Grande/Bajo Rfo Bravo. These
sister cities are included in four high-priority areas each of which will require four
fundamental map units for data compilation.
Atlas preparation will involve a multiyear effort. An illustrative budget for a Year-One
Pilot Study is enclosed. Also enclosed are professional summaries of Bureau

scientists and engineers with expertise in the several different areas needed for this
work.
II. Introduction
The population of the Rio Grande/RFo Bravo Border Area is growing rapidly and with
this growth has come urbanization of the major sister cities and increased
industrialization (about 670 maquiladoras are now located in this area). Growth has
produced major environmental problems: overproduction of limited water resources,
and pollution of surface waters,-ground waters, soils, and air. It is estimated, for
example, that 22 to as much' as 30 million gallons of untreated industrial and urban
waste waters are produced daily by Ciudad Juarez; another 27 million gallons per day
may be contributed to the Rio Grande/Rfo Bravo valley by Nuevo Laredo. Further,
industrial and hazardous waste management practices and abandoned waste
disposal sites are of major concern. Water-related diseases are endemic to some
areas of the border. Air pollution is especially acute in the El Paso-Juarez area.
Potential health effects of industrial, municipal, and agricultural contaminants are of
increasing concern. An area of special interest to both SEDUE and the EPA is the Gulf
of Mexico; the effects of commercial and industrial activity on the land, the Gulf, and the
critical wetlands require monitoring and evaluation.
NAFTA is expected to accelerate development in the Rio Grande/Rfo Bravo Border
Area. This growth will place additional pressure on the environment and increase the
potential for irreparable damage to fragile ecosystems. Clearly, policy makers,
regulators, and decision makers at all levels of government and industry, who are
responsible for guiding the future of the Rio Grande/Rfo Bravo Border Area, from El
Paso del Norte to the Gulf of Mexico beaches, must have reliable information on which
to base their actions.
The Environmental Atlas of the Rio Grande/Rfo Bravo Border Area, as an information
source and analytical tool, is designed to address many of these informational needs.
Importantly, the Rio Grande/Rfo Bravo data base will be binational, encompassing
both sides of the border. To allow formulation of environmental criteria, the data base
will be comprehensive yet capable of being modified so that new information can be
readily added. The data itself will be analyzed and interpreted so that its application is
readily apparent to users at all levels. Further, and vitally so, the data base will be
presented in both Spanish and English versions so that decision makers on both sides
of the border can address common issues from a common set of information. Once
compiled, the data base will serve as a source of baseline environmental data and as
an innovative template for a data base for the entire international border.
III. Attributes of the Atlas of the Rio Grande/Rfo Bravo Border Area
Four priority areas with four fundamental map units per area are shown on figure 1.
Each fundamental map unit will have an east-west dimension of one degree
(longitude) and a north-south dimension of one-half degree (latitude). Each map unit
will be designed to be plotted at a scale of 1:100,000. These dimensions and this
scale correspond to the new set of base maps that the U.S. Geological Survey is in the
process of producing for the entire United States; these maps will have much higher

The data to be included in the Atlas will be divided into several major categories:
ground water, surface water, environmental geology, energy resources, natural
resources, and meteorology. Each of these will have many kinds of detailed
information and will serve as the foundations on which to build data bases for
environmental monitoring and baseline data and for such attributes as, for example,
ranges of plant and animal communities, endangered species, critical ecosystems, soil
types, and archaeological sites. Derivativer maps for land use planning and
combinations-of specific attributes-tor policy analysis can be readily produced that are
tailored to specific- regions within the Border Area. In a given portion of the Border
Area, for example, floodplains, aquifer recharge zones, and steep slopes may be
considered to be the most important attributes in land use planning; in another area,
expansive soils, areas of active erosion, and wetlands may be the critical attributes.
The following paragraphs summarize the kinds of data planned for inclusion in
the major levels of the GIS compilation. Because of the diversity of environments in
the Rio Grande/Rio Bravo Border Area, each map unit will be tailored to portray the
specific attributes that are most relevant-for environmental and planning issues of a
given geographic area.
Surface Water
Surface water resources are vital for both the human and the plant and animal
inhabitants of the border region. The major bodies of surface water are the Rio
Grande/Rio Bravo, Rio Conchos, Pecos River, Amistad Reservoir, Falcon Lake, and
the Gulf of Mexico and associated coastal wetlands. There are about 30 sources that
contribute measurable amounts of surface water to the Rio Grande/Rio Bravo.
Secondary surface waters include the Arroyo Colorado System and irrigation and
drainage canals, many of which are connected to the Rio Grande/Rio Bravo. Other
surface waters are only episodically present in ephemeral streams and desert lakes
(playas). Important surface-water attributes include chemical data on both waters and
modern sediments, floodplains, distribution of wetlands, springs, limits of drainage
basins, and characteristics of surface-water flow (rates and volumes) and other data
from monitoring sites, especially of water quality. Man-made structures that impact
surface-water flow, such as dams, dikes, and areas where channelization have
occurred, should also be mapped. In the coastal areas, additional factors such as tidal
currents and bathymetry may also be included.
The GIS surface-water layer is interrelated to attributes that will be included in other
sets such as the distribution of wetland ecosystems and active surficial processes.
Surface waters are also important as a source of irrigation waters and are important
considerations for land use planning as well as environmental monitoring. Data from
state and federal agencies, including EPA, the International Boundary and Water
Commission, USGS, FEMA, Texas Water Commission, Texas Department of Health,
Texas Water Development Board, and Mexican agencies will be compiled as part of
the surface water layer.

Ground Water
Ground water is one of the most critical resources of the Rio Grande/Rio Bravo Border
Area. The quality and quantity of available ground water is a major constraint on
development of the region. As all available surface waters are allocated, additional
demands can only be met by increasing development of ground water. It is limited in
supply and is subject to contamination if Industrialization, urban growth, and
agricultural practices are not carefQIly managed. In areas of shallow ground water and
locations of ground-water discharge, it is also a critical factor in maintaining many of
the native plant communitiesjand the wildlife that is dependent upon them. For all of
these reasons, ground water wilLbe a central issue in the Atlas. Furthermore, the Atlas
will enhance EPA's support of integrated state ground-water information management
systems.
Four major aquifers lie in the region: the alluvial/bolson aquifer in the Ciudad Juarez-
El Paso area, the-Carrizo-Wilcox aquifer in the Nuevo Laredo-Laredo area, the Gulf
Coast aquifer in the Matamoros-Brownsville area, and the Edwards-Trinity aquifer,
which underlies much of the middle third of the region. Each of these may to some
extent be a transboundary aquifer. Elsewhere most ground-water resources are
limited to local, shallow aquifers or to relatively small aquifers of limited extent such as
those present beneath some of the smaller bolsons.
The ground-water component of the Atlas will include maps of saturated thickness of
the aquifers (mainly for unconfined portions), depth to the base of the aquifers,
potentiometric surfaces, total dissolved solids, hydrochemical facies (concisely
depicting dominance of cation and anion pairs), recharge potential, recharge and
discharge areas, and delineation of confined versus unconfined parts of the aquifers
(important for wellhead protection). Other data specific to environmental monitoring of
aquifers, such as analyses of agricultural or industrial chemicals or other constituents,
might also be included. Maps of factors that will or may change over time, such as
saturated thickness, for example, must be dated. The maps will be supplemented with
historical hydrographs and other data to the extent possible. The potential yield of
wells in major aquifers will be indicated by tables of typical hydrologic properties such
as hydraulic conductivity and storage coefficients.
Water quality issues are primarily related to either salinization or humanly induced
contamination. Salinization occurs as a result of
(1)	seawater intrusion (Gulf Coast aquifer)
(2)	recharge of evaporatively concentrated saline irrigation waters (alluvial and
bolson aquifers)
(3)	brines from oil and gas wells or improper disposal of related brines,
(4)	water wells drilled into salt water zones and improperly sealed, and
(5)	natural discharge of saline waters.
The interpretation of processes that control salinization in data-rich areas can be used
to predict the potential for salinization in areas of sparse data. Aquifer contamination
can also occur as a result of human, municipal, industrial, and agricultural wastes
being dissolved or suspended in waters that recharge aquifers. The range of possible
contaminants, metals, bacteria, viruses, and various organic and inorganic chemicals,

is broad. Characterizing natural TDS and major ionic composition can be
accomplished using relatively sparse data because the natural geologic controls tend
to be regional in character; characterizing contaminants requires much more specific
data because the sources tend to be localized. Publicly available data on
contaminants should, however, be included in the Atlas as it becomes available to
indicate the current state of the environmental quality of the aquifers.
Year One efforts will emphasize obtaining and collating extant records and
reconnaissance work to characterize well development, typical well construction, and
an evaluation of the feasibility of measurement, sampling and testing to supplement or
create the needed data base. Preliminary compilations of hydrologic maps of the
major aquifers will be based on existing data. Much of the required data are available
for the Texas side of the border. Well locations, water-level measurements, chemical
analyses, stratigraphic characteristics, and hydrologic property tests can be found <-
the publications and files of various state and federal agencies. Archived state recorc*
probably include information on over 80 percent of the wells over 50 ft in depth but
likely less than 20 percent of the shallow hand-dug wells serving rural homesites and
ranches. The availability of comparable data in Mexican government files must be
determined.
The text that will accompany the maps will discuss recharge, flow, and discharge of the
major aquifers, and chemical composition as it relates to human, agricultural, and
industrial uses. It will also identify areas for potential aquifer development and typical
well construction that would be required for a range of yields in the various aquifers.
Other more difficult issues, such as extent of aquifer development and potential for
expansion, and ground-water contamination, could also be addressed via products
such as aquifer vulnerability maps. Information from the Texas Water Development
Board, which tracks historical and future water demands, together with historical
hydrographs of water-level change will give some indication of the potential for safe
expansion of aquifer production relative to recharge rates. Eventually, ground-water
flow models should be developed to quantitatively assess impacts of water
development throughout the Border Area, and to address how aquifers are
interconnected across the border and how they interact with surface waters of the Rio
Grande/Rfo Bravo.
Environmental Geology
The attributes of the environmental geology layers will reflect the heterogeneous
characteristics of the soils, sediments, rocks, physiography, and active geologic
processes that are present in the Border Area. Geologic data are an essential part of
the Atlas as the characteristics of the surface and upper crustal levels of the earth
determine such things as how and where structures are built, where agriculture is
possible, how recharge of aquifers occurs, the productivity of aquifers, and the ability
of the natural environment to retard transport of contaminants from landfills and
repositories. Units will be selected and features will be portrayed that are most
relevant to the land use and environmental issues of a particular geographic area.
The two major categories of geologic units will be those that are subdivisions of
consolidated rock types and those related to unconsolidated sediments and soils.

Subdivision of the bedrock units will reflect geotechnical characteristics, major
lithologies, and units having features of special importance for recharge or land use
planning (such as karst terrains). Soils and sediments will be subdivided according to
their geotechnical, chemical, or grain size characteristics. In most cases, both rocks
and sediments will first be mapped based on well-established geologic principles and
then reclassified into units appropriate for planning purposes. Particular attention will
be given to units that host aquifers or are the major recharge zones for aquifers.
Other geologic attributes, in addition to the character of the soils, sediments, and rocks,
will also be addressed. The physiography of the land and the analysis of slopes and
topographic gradients will be important in some areas. Active geologic processes are
present, or the potential for active processes exists, throughout the region. Active
fluvial erosion, coastal processes, channel migration, flash floods, wind erosion or
deposition, landslides, subsidence, and earthquake-induced faulting have all locally
occurred, or are now active, in parts of the Border Area.
Much pertinent information is available from the Bureau of Economic Geology, the
U.S. Geological Survey, the U.S. Soil Conservation Service, and other agencies and
published sources but has not been critically compiled to meet Atlas objectives. In
addition, interpretation of aerial photographs will be used to supplement published
sources or to map features and units of particular concern to the Border Atlas. Some
field work will be needed to verify interpretations and to collect samples for analysis.
Energy Resources—Petroleum
Mexico and the United States have many interrelated concerns regarding energy and
the environmental impact of its development and use on the Border Area. These
issues include environmental concerns related to the air emissions produced by
burning of fossil fuels, availability of energy supplies, transportation of energy
resources and products (by land and by sea), development of new energy resources
(petroleum, coal, lignite, and geothermal), and refining of hydrocarbons.
The U.S. is Mexico's major market for oil exports, accounting for more than 56 percent,
or 720 million bbl, of the 1,277 million bbl produced in 1990. Recently Mexico has
experienced an increased internal demand coupled with inadequate current and
future refining capacity. Mexico's Ministry of Energy, Mines, and State Owned Industry
indicates that levels of per capita oil consumption in Mexico will increase from 10.1
barrels of oil equivalent (BOE) in 1990 to 10.6 BOE in 1992 to 11.3 BOE in 1994, and
will require a doubling of the current refining capacity from 1.5 million b/d to 3 million
b/d by the year 1994.
Increased industrial activity in the Border Area, decreased exploration and production
expenditures by Petroleos Mexicanos (Pemex) in the onshore Sabinas Basin, and
decreased prices for U.S. gas, which has provided a cheap source of more
environmentally benign energy for the maquiladoras, has shifted northern Mexico from
a net exporter of natural gas to the U.S. to a net importer. At the end of 1991, Mexico
was importing approximately 300 million cubic feet per day (MMcfd) of U.S. natural
gas; current U.S. gas exports to Mexico are 350 MMcfd through interconnects at
Reynosa, Piedras Negras, Ciudad Juarez, and Naco.

The U.S. and Mexico oil and gas resources within the Rio Grande/Rfo Bravo Border
Area are primarily linked by the petroleum resource characteristics of the Gulf of
Mexico Basin (GOM). In general, these petroleum resources are dominated by gas
over oil. The GOM petroleum subprovinces of the border region include the onshore
Burgos-Sabinas basins and Maverick basins of Mexico, and the Rio Grande/Rio Bravo
Embayment of the onshore and offshore Gulf Coast of the U.S. The Reynosa field,
which produces mostly from the Frio trend in the Burgos basin, is the only giant field
(>*500 million BOE known recovery) that directly straddles the-border. Estimates of gas
resources in northern Mexico vary from 7.3 Tcf to 36 Tcf. Adjacent giant fields in the
U.S. include Stratton-Agua Dulce, Borregos-Seeligson-T.C.B. and La Gloria.
Petroleum resources outside of the GOM basin but within 100 km of the border occur
in carbonate reservoirs of West Texas, but none*of the major oil resources of West
Texas occur within the Border Area.
An accurate assessment of the petroleum resources in the Rio Grande/Rio Bravo
Border Area will require analysis of trends and plays containing multiple fields and
reservoirs. Tasks will include (1) compiling a data base of individual plays within each
subprovince. (2) documenting the location and status of producing and abandoned
fields, and (3) classifying the reservoir types, depth range, reservoir quality, and
cumulative production for each product type (crude oil, natural gas, and natural gas
liquids). Final products would include GIS maps at the scale of 1:100,000 showing
trends, plays, fields, and reservoir types within each petroleum subprovince and the
delineation of the current and proposed pipelines, interconnects, and refineries in the
border region.
Energy Resources—Coal and Geothermal
The Rio Grande/Rfo Bravo Border Area also contains coal and lignite resources and
areas favorable for the development of geothermal energy. In this area, coal, ranging
in rank from lignite to bituminous, occurs in lower Tertiary and Upper Cretaceous
strata. Deposits of commercial size and quality are present on both sides of the border.
The Eagle Pass coal field was-one of the most productive in Texas, having major
production between the 1880's and 1920's. Coal currently mined near Piedras
Negras, Coahuila, is burned to generate electricity. The increase in industrial
development along the Border Area may result in an increase in coal production. The
Environmental Atlas will include data on the many locations of known coal resources
and occurrences in the Border Area and an assessment of potential areas that may
host undeveloped coal deposits.
Substantial geothermal resources are present in the Rio Grande/Rio Bravo Border
Area, particularly in South Texas, where the resources are geopressured. and in
Trans-Pecos Texas. Although less well known, these favorable environments for
geothermal energy also continue into adjacent areas of Mexico. These resources are
too low temperature, in general, for the economic generation of electricity, but they are
of sufficient quality for other commercial uses such as space heating, aquaculture.
greenhouses, and drying of agricultural crops. The location of known geothermal
resources and the temperature and quality of the geothermal waters wilt be compiled
as part of the Atlas.

Mineral Resources
The Rio Grande/Rfo Bravo Border Area has numerous occurrences of metallic and
nonmetallic mineral commodities, including raw materials of value for local
construction, e.g., sand and gravel, limestone, crushed rock and asphalt. Some
deposits may also be contributing trace amounts of metals or other ions to surface or
ground waters that may cause elevated levels of these chemicals in soils, surface
waters, or ground water. The presence of these resources-should be considered as
part of any comprehensive plan for development. Production of these resources may
result in environmental issues that will have to be addressed. The Bureau of Economic
Geology will be a principal source of information for mineral occurrences in the Border
Area in the United States. The U.S. Geological Silrvey has a digital data base of some
of the mineral occurrences in Mexico. The locations of mineral prospects and deposits
will be compiled for each map unit. Each location will be annotated to indicate
commodities present and whether or not the commodity has been commercially
produced.
Meteorologlc Data
The climate of the Rio Grande/Rfo Bravo Border Area ranges from the semiarid of
upstream areas to the tropical of the Gulf Coast. Climate and meteorological factors
influence not only such things as agricultural practices, but also quantity and quality of
surface waters, dispersion of air-borne pollution, rates of recharge, and geological
processes. Meteorologic data compiled as part of the Environmental Atlas will include
wind speed and direction, temperature, humidity, precipitation, and pan evaporation
data, where available for those map units that have meteorological stations. Data on
air quality are a related environmental attribute that can be included for those places
where monitoring stations have been established, such as in the Ciudad Juarez-El
Paso airshed. This information will be useful to those seeking to develop climate-
sensitive industry, such as aquaculture or greenhouse agriculture, and for those
charged with environmental monitoring.
Cultural and Biologic Data
The above-mentioned types of data will serve as the fundamental layers in the GIS
Atlas upon which other equally important layers can be built. Such information as
ranges of plants and animals, occurrences of endangered species or fragile
ecosystems, or sites of historic or archaeological importance can be readily built into
the data base. Further, a striking feature of GIS is that it enables a scientist trained in a
single discipline to examine the interrelationships among different layers that may not
otherwise be readily apparent A particular plant community, for example, may occur
only in areas underlain by a specific geologic unit. This will also permit a comparison
of the environmental monitoring data, such as heavy metal concentrations in
sediments or soils, with biologic data.

IV. Scope of Work, Year-One Pilot Study
A. Area of study
Six sister city pairs astride the Rio Grande/Rfo Bravo would be accorded priority status:
(1)Ciudad Juarez-El Paso. (2) Ciudad Acufta-Del Rio, (3) Piedras Negras-Eagle
Pass, (4) Nuevo Laredo-Laredo, (5) Reynosa-McAllen, and (6) Matamoros-
Brownsville. We propose that initial efforts be focused on either the twin-city area at the
upper end of the Rio Grande/Rfo Bravo, Ciudad Juarez-El Paso, or the Lower Rio
Grande/Bajo Rio Bravo including Reynosa-McAllen and Matamoros-Brownsville.
1.	Ciudad Juarez-El Paso: The Ciudad Juarez-El Paso area is a critical
area because it contains the majority of the maquiladoras of the Rio
Grande/Rio Bravo Border Area and is subject to a host of environmental
concerns. Water quality and water resources for these cities are issues
involving both surface and ground water and are international in scope.
Both cities obtain most of their water supplies from a shared, transboundary.
ground-water aquifer in the Hueco Bolson, a finite resource that is already
over-produced. The cone of depression associated with the Juarez
production wells has crossed the border into the United States, and El Paso
is so concerned about future water supplies that it has recently purchased
water rights to an area over 140 mi (225 km) to the southeast in northern
Presidio County. Texas.
The shallow Rio Grande/Rfo Bravo aquifer, a local source of water for
colonias on both sides of the border, and the surface waters of the Rio
Grande/Rfo Bravo are under threat of contamination by up to 30 million
gallons a day of untreated industrial and municipal waste waters. The
surface and shallow subsurface waters are also subject to contamination by
agrichemicals, especially pesticides and perhaps defoliants, and
salinization is effecting the soils of agricultural areas, but the extent of these
problems has not yet been documented.
Air quality in the Ciudad Juarez-El Paso area is a major problem currently
being investigated. To help improve air quality, new gas pipelines are being
built from Ei Paso to Juarez to provide a cleaner burning fuel for both
power plants and industry. An additional pipeline to carry 105 MMcf/day to
the Samalyuca power plant complex will be needed by 1994.
Industrialization and urbanization of the Ciudad Juarez-El Paso area is
continuing at a rapid pace. The information to be provided in the
Environmental Atlas will be of fundamental importance in planning for
responsible development and in monitoring the environmental conditions of
the Ciudad Juarez-El Paso area.
2.	Lower Rio Grande/Bajo Rfo Bravo: The Matamoros-Brownsville, and
nearby Reynosa-McAllen, sister cities have a litany of environmental
concerns similar to those of other developed areas along the border. In
addition, however, the location of this area, adjacent to the Gulf of Mexico,
and the presence of large petroleum resources and related industry make it
Pag* 284

-------
somewhat unique compared to other sister-city areas. The Gulf Coast-Rio
Grande/Rfo Bravo Delta and Lower Rio Grande/Bajo Rfo Bravo host large
wetlands, active coastal processes, areas subject to coastal flooding due to
tropical storms and hurricanes, and aquifers subject to salinization by
seawater intrusion. There is also a threat of environmental contamination
due to the inadvertent release of petroleum or other hazardous chemicals
as a result of a marine accident. The special character of this environment,
and the importance of its ecosystems, will require an extra level of care in
assessing risks associated with development.
The Matamoros-Brownsville area, at least on the north side of the Rio
Grande/Rfo Bravo, has a head start in the compilation of the environmental
data base due to previous work by the Bureau of Economic Geology. As
culmination of work extending from 1969 to the late 1970's, the Bureau
published a series of maps and accompanying texts, the "Environmental
Geologic Atlas of the Texas Coastal Zone," that addressed many of
the environmental issues of the Texas Gulf Coast. This work was divided
into 7 segments, and the maps and related products for the final segment—
Brownsvllle-Harllngen—was published in 1980. Although some of the
information is dated (man-made features and current land use), much of the
basic data are still valid. Information on the environmental geology maps
(physical properties, land-surface subsidence, faulting), active processes
map (hurricane flooding, shoreline processes, other active processes), and
the topography and bathymetry map can be utilized with little modification.
Other characteristics (mineral and energy resources, construction raw
materials, water systems, coastal wind regimes, tidal currents, and river
discharge) can be updated with current data. Additional data sets in the
coastal atlas will be extremely useful as indicators of environmental change
(distribution of wetlands and marshes, subaqueous and subaerial
environments and biologic assemblages).
Further, a companion set of studies to the Atlas, the "Submerged Lands
of Texas," was prepared by the Bureau of Economic Geology based on
extensive data yathered and sampled in the same time frame as the Atlas.
The Brownsvllle-Harllngen set was published in 1986. It includes
detailed information on the geochemistry, sediments, benthic
macroinvertebrates, and wetlands of the coastal areas and is a premier
¦ data set for evaluating environmental changes over the past decade.
Together, the Coastal Atlas and the Submerged lands volumes are an
outstanding example of the utility of compilation of basic data and will be an
invaluable resource for the Matamoros-Brownsville portion of the
Environmental Atlas of the Border Area.
B. Objectives and Approach
Year One will produce a clear template for future work on the Atlas regardless of which
area is selected as a starting point (or if it is determined that some work should occur
in each area). Preliminary maps of selected critical elements that will be of immediate
benefit to the study area(s) will be produced. Other goals are to assess availability of

data (especially from Mexico), establish contacts with the key individuals or agencies
that have relevant information, and establish protocols for efficient data acquisition,
data entry, and data analysis that will guide all future work on the project.
Data available from Mexico will be less extensive than that from the United States.
However, it is important that all relevant data be included in the Atlas. One purpose of
the Atlas is to portray the available data so that areas of inadequate information can be
recognized and, if the data are critical to analysis of a particular issue, the data gap
can be rectified. For example, on the U.S. side of the border, there are areas where the
basic data on water wells (location,.depth to the static water level, and basic chemistry)
are likely incomplete. Compilation of available data will indicate places where testing
of a few wells will provide sufficient supplementary information to adequately descnbe
the characteristics of aquifers under consideration for development.
To assist in the gathering of information on Mexico, we may draw on other components
of the University of Texas System located near the border, e.g., El Paso, Pan-American
at Edinburg, Brownsville, or San Antonio. Many o? the scientists at these universities
conduct research in Mexico and have contacts at Mexican universities and with
Mexican officials. Internships or assistantships will be provided to students, some of
whom may be Mexican nationals, to compile and analyze data on Mexico. This
approach not only will be in the best interests of the project, but also it will help train
future environmental scientists. Identification of Mexican data sources and acquisition
of published reports or other information will be a challenging activity during year one.
Ground water, environmental geology, and perhaps surface water or energy resources
will be the focus of Year One activities. Locations of water wells, elevation of the water
table, and water chemistry are of special interest for the ground-water data base. The
Texas Water Commission, Texas Water Development Board, U.S. EPA, SEDUE, U.S.
Geological Survey, local water districts, and previous studies by the Bureau of
Economic Geology are sources of data. Geologic units, active geologic processes,
soils, geohydrologic units, and other geologic factors important for land use planning
of the area being studied would be emphasized as part of the environmental geology
compilation. Geological data are available from the Bureau of Economic Geology, U.S.
Geological Survey, professional journals, and various Mexican sources such as the
Sociedad Geologica Mexicans and publications of geological institutes at the northern
Mexico universities. Data for the surface water map will include perennial streams and
rivers, springs, floodplains, wetlands, and water and sediment analyses. FEMA and
the International Boundary and Water Commission have determined floodplains for
much of the Border Area, and some data are available on surface water quality.
Energy resources, especially Important in the Matamoros-Brownsville area, will be
compiled if the lower Rio Grande/Rfo Bravo is part of the focus of year one activities.
Previous compilations of the United States portion of the Border Area by the Bureau of
Economic Geology will provide a major part of the data; publications by the Asociacion
Mexicana de Geologos Petroleros and other professional literature will provide
information on Mexican energy resources.
Critical GIS procedures and protocols that will guide future activities on this project will
be established during Year One. Contact with the EPA's Environmental Monitoring
Systems Laboratory in Las Vegas and their Spatial Analysis Laboratory, a Center of

Excellence for GIS, will be helpful in this effort. Geographic data bases will be created
in an ARC/INFO GIS format. Each layer will have both a Spanish and an English
language annotation layer, or perhaps a single bilingual annotation layer, with
explanatory information. The finalized layers can be manipulated by ArcView software,
but the user will be precluded from editing the finalized data. Procedures will be
established that describe when and how a layer can be edited and how those
changes will be documented. Hard copies of layers may be plotted using a color
electrostatic plotter that produces very high quality (400 dots per inch) graphics.
In summary, Year One results will produce (1) examples (preliminary maps) of some
of the principal types of data that can be compiled, (2) an assessment of data
availability for a variety of potential layers. (3) identification of potential sources of
data, and (4) standardized procedures for ARC/INFO data base creation. The Year-
One pilot study will demonstrate the utility of the GIS approach to formation of an
environmental data base for planning and decision making and will provide a realistic
example of the potential of the Environmental Atlas of the Rio Grande/Rio Bravo
Border Area.
V. Capabilities of the Bureau of Economic Geology
The Bureau of Economic Geology is a geologic and hydrogeologic research group at
The University of Texas at Austin with an international reputation for multidisciplinary,
basic and applied research in the geosciences. Since 1909, the Bureau has carried
out the functions of a State Geological Survey. Bureau studies include a wide range of
topics in diverse settings both in the United States and in other countries. The Border
Area has been a focus for Bureau studies since the early decades of this century. This
long tradition of investigations of the geology, hydrology, and resources of the Border
Area continues today with currently active projects in the western Trans-Pecos, Big
Bend area, South Texas, and the Gulf of Mexico.
The Bureau of Economic Geology has been involved in studies in the broad
disciplines of environmental geology and hydrology for many years, and is a
recognized leader in the compilation of regional data sets. The "Environmental
Geologic Atlas of the Texas Coastal Zone," "Submerged Lands of Texas,"
"Atlas of Major Texas Oil Reservoirs," "Atlas of Major Texas Gas
Reservoirs," and the "Geologic Atlas of Texas" are nationally known
publications that have established the Bureau as a leader in the compilation and
presentation of regional studies. Several of these publications will be primary sources
of data for the Environmental Atlas of the Border Area.
The Bureau of Economic Geology has a large full-time research staff of experienced
earth scientists and engineers with diverse interests and an excellent support staff of
professional editors, cartographers, and computer scientists. Our modern facilities and
state-of-the-art equipment can address a wide range of investigations. We are
experienced in managing large multidisciplinary projects that require coordination with
state and federal agencies and industry both in the United States and internationally.
The capabilities of our computer staff and our computing hardware and software are of
particular importance to the GIS applications planned for the Environmental Atlas of
14

the Border Area. The Computer Resources section supports programming, data base
applications, statistical and graphic analysis of data, and computer mapping and
modeling on the Bureau's computer system and on the University's IBM, VAX,
CONVEX, and Cray computer systems.
The Bureau's computer system consists of a Local Area VAX Cluster (LAVC) with a
VAX 4000 as a boot node. Three VAX 3100s and a MicroVAX II serve as satellite
nodes in this LAVC. Additional nodes include a DECstation 5000, a Silicon Graphics,
Inc. (SGI) Personal Iris workstation, and two SGI Indigo workstations. All workstations
are accessible through the Bureau's Zyplex terminal server. A print server provides
network accessibility to a line-printer and laser printer. An Ethernet network is the in-
house connection for all workstations (fig. 2). Additional computing capabilities include
72 Macintoshes, 19 IBM-compatible PCs, 15 Apple LaserWriters, 5 pen plotters, an
electrostatic plotter, 108 OEC terminals, and 5 digitizing tablets. All Macintoshes are
networked into a LocalTalk network that connects to the Bureau's Ethernet. The
Bureau's local networks are connected to UTs broad-band Ethernet system, which
allows high-speed communications with computer systems on campus and at the
Center for High Performance Computing. Internet and BITNET provide worldwide
networking capabilities.
In addition to providing VAX VMS, ULTRIX, UNIX. DOS. Windows, and Macintosh
operating systems, software capabilities include third- and fourth-generation data base
tools, word processing, spreadsheet, and statistical packages. Graphics and
environmental modeling capabilities include graphics programming libraries, contour
mapping, image processing, and data plotting in two and three dimensions. Seismic
data display, interpretation, and modeling capabilities are provided on both
workstations and Macintoshes. Additional capabilities include water flow modeling,
reservoir modeling, and well log interpretation.
Geographic Information System (GIS) capabilities have been expanded to include
ARC/INFO and ArcView software, and a DECstation 5000 workstation. IBM-compatible
PCs, Macintoshes, and X-terminals will serve as additional "seats" on the system.
Output capabilities will consist of both color and black-and-white electrostatic plotters.
GIS capabilities currently include PC ARC/INFO installed on two IBM-compatible PCs.
Data input is through digital files, keyboard, and Calcomp digitizers. Hard-copy maps
are generated using Hewlett Packard DraftPro plotter, 7475 plotter, and LaserJet
Series II printer. Staff training specific to GIS includes courses in PC ARC/INFO,
Introduction to Workstation ARC/INFO, and Customizing ARC/INFO with AML Our GIS
specialist has a degree in Cartography and Photogrammetry. The BEG computing staff
includes six full-time professionals and additional support staff.
The head of our computing staff also serves on the Texas Geographic Information
Systems Planning Council as a member of the GIS Base Map Requirements
Definition Team. This Council was charged by Governor Ann Richards with the
responsibility of:
Planning for the most cost-effective means of acquiring and
distributing geographic information to the state as a whole and
P«0«288

ensuring that agency programs are in concert with other state and
federal agencies.
Developing a business plan to prioritize and schedule the
development of public-funded programs for the acquisition of
geographic information of common interest, and to seek partners in the
public sector for data development.
Identify agencies to serve as data custodians and define the roles and
responsibilities for the agencies' data steward-ship.
Participation as part of this council will ensure that the GIS format used for the
Environmental Atlas of the Border Area is compatible with that of other state and
federal agencies and that the Atlas can take advantage of other GIS work being
accomplished by the State in this area.
