Executive Summary
Communities across the country want to protect their water quality while also getting the
greatest possible benefit out of every investment they make. Many are conserving, restoring, or
enhancing natural areas while incorporating trees, rain gardens, vegetated roofs, and other
practices that mimic natural systems into developed areas to manage rainwater where it falls.
These types of approaches, known as "green infrastructure," are an integral component of
sustainable communities primarily because they can help communities protect the environment
and human health while providing other social and economic benefits, allowing communities to
achieve more for their money. Using green infrastructure strategies to reduce stormwater runoff
can strengthen efforts to preserve open space and natural areas and encourage development in
existing communities. Green infrastructure elements help make neighborhood streets and
greenways pleasant and safe for walking and biking and reinforce a sense of place. Integrating
green infrastructure and sustainable communities encourages collaboration in development
decisions and promotes green building practices.
Engaging the entire community creates a vision for the future based on people's and businesses'
needs, desires, and aspirations. This vision guides the plan and ultimately implementation. A
sustainable communities and green infrastructure plan will touch nearly every aspect of a
community's design. Involving a wide range of community members in developing both the
vision and the plan creates broad support and encourages multiple champions to emerge to
handle different aspects of implementation. Such broad-based involvement also helps ensure
people from all walks of life, including vulnerable and disadvantaged populations, can share in
the benefits that come from implementing a green infrastructure plan.
Successful plans include clear goals, an assessment of assets and opportunities, a
comprehensive look at how to achieve implementation, a means for funding implementation, a
way to monitor and measure progress toward achieving the community's goals, and a strategy
for long-term operations and maintenance. With such a plan in place, a community will be well
on its way to improving quality of life, protecting the environment, improving public health,
becoming economically stronger, and preparing for climate change impacts.

I. Introduction
Communities across the country want to protect their water quality while also getting the
greatest possible benefit out of every investment they make. Many are conserving, restoring, or
enhancing natural areas while incorporating trees, rain gardens, vegetated roofs, and other
practices that mimic natural systems into developed areas to manage rainwater where it falls.
Using these types of approaches, known as "green infrastructure," to reduce stormwater and
pollution runoff is a way of protecting water quality while achieving cobenefits that can include
improved public health, better quality of life, and economic development.

throughout a new 1 7-mile loop of
interconnected parks and
greenways.1 Each park serves multiple purposes, including improving public health by
encouraging use of the trail system, providing recreation opportunities in underserved
communities, supporting biodiversity and creating habitat, providing job training for young
people, encouraging walking and bicycling, and reducing ambient air temperatures. For
example, the organization created Lashbrook Park along an existing bike trail by constructing a
bioswale filled with native, drought-tolerant plants along the park's length to infiltrate
stormwater, adding picnic areas and benches, and installing interpretive signage in the Tongva
Indian language.2
Green infrastructure can not only help improve water quality by better managing stormwater—
sometimes even at a lower cost than conventional alternatives—but also can attract investment;
help revive distressed neighborhoods; encourage redevelopment; provide recreational
opportunities; and help achieve other social, economic, public health, and environmental goals.

Introduction
neighborhood groups, and other stakeholders integrate green infrastructure strategies into
plans that can transform their communities. Many communities that want to use green
infrastructure approaches face technical, regulatory, financial, and institutional obstacles that
limit widespread implementation.3 This document serves as a guide to develop a plan that can
overcome these obstacles for neighborhoods, towns, cities, and regions of all sizes. It helps
stakeholders create a vision for how green infrastructure can enhance their communities—a
vision that engages residents and inspires them to take action. It also directs readers to other
resources that provide more detailed information that can be tailored to communities'
particular climate, goals, and circumstances. This introductory section describes:
A. What green infrastructure is.
B. What sustainable communities are.
C. Why green infrastructure is an integral component of sustainable communities.
Following the introduction,
• Section II describes strategies that support both sustainable communities and green
infrastructure.
• Section III explains how to organize stakeholders.
• Section IV outlines the different activities that are part of developing a sustainable
communities and green infrastructure plan.
• Section V concludes with a review of best practices for creating a sustainable
communities and green infrastructure plan.
A. Green Infrastructure
In developed areas, much of the land is covered by buildings, pavement, and other
impermeable surfaces that prevent rain and snowmelt from soaking into the ground. Instead,
this water runs off, often flowing directly to streams, rivers, and other water bodies. It can carry
pollutants such as oil, chemicals, and lawn fertilizers. In addition, the quantity and speed of
flow can cause erosion, flooding, and damage to aquatic habitat, property, and infrastructure.
Green infrastructure includes a range of approaches for managing stormwater near where it
falls. Most green infrastructure uses the natural processes of soils and vegetation to capture,
slow down, and filter runoff, often allowing it to recharge ground water, but some practices

collect and store rain water for future use. Some techniques, including using permeable
pavements, bioswales, rain gardens, vegetated or "green" roofs, rain barrels, and cisterns, work
at the site scale and can fit into individual development, redevelopment, or retrofit projects.
Larger-scale management strategies, including preserving or restoring flood plains, open space,
wetlands, and forests, can be used at the watershed level.4
In contrast to green infrastructure, stormwater in cities has historically been managed by
expansive and capital-intensive underground storm sewer systems. This "gray infrastructure"
has the single purpose to collect and carry runoff from city streets, parking lots, and other
impervious surfaces as quickly as possible. Many communities are now looking to combine gray
and green infrastructure approaches to manage stormwater to achieve multiple community
goals. The most appropriate techniques in a given location will depend on goals, budget, and
other context-specific factors, but green infrastructure can be designed to work in nearly all

B. Sustainable Communities
Sustainable communities are places that balance their economic assets, natural resources, and
social priorities so that residents' diverse needs can be met now and in the future. These
communities prosper by attracting and retaining businesses and people and offering individuals
of all incomes, races, and ethnicities access to the opportunities, services, and amenities they
need to thrive. To become more environmentally and economically sustainable, many
communities use smart growth approaches—a range of strategies that cities, suburbs, towns,
and rural areas can use to protect the environment and public health, support economic
development, create strong neighborhoods with diverse housing and transportation options,
and improve residents' quality of life. Exhibit 3 lists the principles that underlie smart growth
strategies.6

Introduction
Exhibit 3: Smart Growth Principles
In 1 996, the Smart Growth Network—a group of more than 30 national organizations representing a range of
interests including real estate; the environment; community development; affordable housing; and local,
state, and federal government—developed 10 smart growth principles:
• Mix land uses.
• Take advantage of compact building design.
• Create a range of housing opportunities and choices.
• Create walkable neighborhoods.
• Foster distinctive, attractive communities with a strong sense of place.
• Preserve open space, farmland, natural beauty, and critical environmental areas.
• Strengthen and direct development towards existing communities.
• Provide a variety of transportation choices.
• Make development decisions predictable, fair, and cost effective.
• Encourage community and stakeholder collaboration in development decisions.

C. Green Infrastructure Is an Integral Component of
Sustainable Communities
Green infrastructure is an integral component of sustainable communities primarily because it
can help communities protect the environment and human health while providing other social
and economic benefits. In addition, green infrastructure and sustainable communities
approaches can help local governments that are struggling to pay for needed upgrades to
stormwater and wastewater infrastructure that is beyond its intended lifespan. These challenges
are likely to grow as a changing climate further strains public infrastructure and municipal
finances. For example, the projected increase in extreme weather events will likely increase
service disruptions in some locations, particularly those near climate-sensitive environmental
features like coastlines, rivers, storm paths, and vegetation in arid regions.7 Adapting
infrastructure so that it is more resilient to these types of changes will be expensive.
1. Benefits
Many communities need significant investments to upgrade existing water infrastructure and
prefer solutions that are not only cost effective but also provide additional benefits. Many
property owners see their role in stormwater management as solely to ensure that it flows from

Introduction
their property as quickly as possible to prevent
flooding—property owners have largely not had to
concern themselves with where stormwater goes.
Now, as communities are facing mounting bills for
safely dealing with that stormwater, they are hoping
to shift public understanding so property owners
recognize stormwater as something they should
either manage on site or pay to have removed,
much as they have long been used to paying for
snow removal and municipal trash service. Green
infrastructure offers a way to address this
challenge: it provides tools for property owners to
manage stormwater themselves, and it offers
additional tangible environmental, economic, public
health, and social benefits (Exhibit 4).
For example, green infrastructure and sustainable
communities strategies can help communities adapt
to climate change. Many communities are not
adequately prepared for current weather extremes,
much less projected future impacts. Depending on
the region, these changes could include higher
temperatures, more extreme weather events,
changes in precipitation patterns, and sea-level rise.
These changes can strain water infrastructure,
reduce water supplies, worsen water and air pollution, and increase flooding because of more
intense downpours and higher storm surges.8 Sustainable communities strategies can help
communities become more resilient to these challenges by encouraging development in safer
locations, promoting water- and energy-efficient buildings and neighborhoods, providing
transportation options that people can use every day as well as in an emergency, and helping
protect the populations most vulnerable to climate change impacts—the very old and very
young; people with chronic health problems; non-English speakers; and residents of low-

income, minority, and overburdened communities.9 Incorporating green infrastructure can
further increase community resilience by filtering polluted stormwater, recharging ground water
supplies, reducing ambient air temperatures by adding greenery, and providing retention areas
that slow runoff.10.11
Recognizing such benefits,
the city of Chicago's
Climate Action Plan calls
for 6,000 new green roofs,
more than a million new
trees, a watershed plan that
factors in changes
expected due to climate
change, and other
actions.12 In the first two
years after implementation,
more than 4 million square
feet of green roofs were
completed or planned, and
32,000 square feet of
Chicago alleyways were
reconstructed with
permeable materials.13
Exhibit 5. Green roof on City Hall, Chicago, Illinois. The city of
Chicago created a green roof on its city hall to test the performance of
the technology and understand how green roofs could help the city
achieve its climate action goals. The roof can be as much as 30 degrees
cooler than surrounding roofs in the summer. It reduces the use of air
conditioning in the building while absorbing rainfall that would otherwise
run into storm sewers.
Unlike gray infrastructure, which serves only to manage stormwater, green infrastructure allows
a local government to make the most of limited public dollars and achieve multiple goals with a
single investment. Many cities already take advantage of the multiple benefits of green
infrastructure. The watershed management plan of Portland, Oregon, for example, prioritizes
areas ripe for redevelopment and infill when deciding where to make green infrastructure

strategies to acquire additional parkland in underserved neighborhoods, expand the off-street
bicycle network, and remove barriers to the expansion of community gardening.
2. Potential Cost Savings Compared to Gray Infrastructure
Every 4 years, the U.S. Environmental Protection Agency (EPA) prepares a report to Congress,
based on a survey of states, on the unfunded capital costs for projects to address water quality
or water quality-related health problems.16 As of 2008, states had identified the need for $63.6
billion to address combined sewer system overflows17 and $42.3 billion for stormwater
management.
One approach to address combined sewer overflows is to replace a single combined sewer
system with separate storm and sanitary sewer systems. Directing storm sewer flows directly to
waterways and sanitary sewer flows to treatment plants can ensure that the sanitary sewer
system does not exceed capacity during periods of heavy rain or snowmelt. However, system
separation is expensive and leaves untreated stormwater flowing directly to rivers, lakes, and
estuaries. Another approach is to construct underground facilities that can hold excess
wastewater from combined sewer systems until a treatment plant has the capacity to handle it.
However, underground storage facilities are expensive and take many years to construct. By
contrast, cities can implement green infrastructure solutions over time and produce incremental
results towards achieving their long-term goals.

17 Combined sewer systems collect stormwater runoff, domestic sewage, and industrial wastewater in the same pipe.
Most of the time, combined sewer systems transport all of their wastewater to a sewage treatment plant. During periods
of heavy rainfall or snowmelt, however, the wastewater volume can exceed the system's capacity resulting in an
overflow to nearby streams, rivers, or other water bodies.
-------
Introduction
In some cases, green infrastructure can reduce costs by decreasing the amount of stormwater
gray infrastructure systems must be designed to manage. For example, in 201 3, EPA approved
a plan by the Metropolitan Sewer District of Greater Cincinnati to control combined sewer
overflows stemming from the Lower Mill Creek service area using green infrastructure, along
with strategic sewer separation and other methods.18 This approach using both gray and green
infrastructure is projected to save $1 50 million compared to the city's original plan to construct
a deep tunnel stormwater storage area—even before considering other potential economic
benefits.19
The Philadelphia Water
Department
commissioned a study
comparing alternatives
for controlling its
combined sewer
overflows that measured
the value of various
environmental, social,
public health, and other
benefits.20 Across all city
watersheds, the total net
benefits over 40 years
ranged from $1.9 billion
(in 2009 dollars) for an
option that included
managing 25 percent of
impervious surfaces in the city through green infrastructure to $4.5 billion for an option that
included managing 1 00 percent of impervious surfaces through green infrastructure. The total
net benefits for options that included managing stormwater through a system of storage

Introduction
tunnels ranged from just $61.6 to $1 40 million over the same period, depending on the size of
the tunnel system.
Green infrastructure can also save money for places that do not have combined sewer systems
needing upgrades. An EPA report on 1 7 projects using site-scale green infrastructure found
that in most cases, green infrastructure was cheaper and performed better environmentally
than conventional stormwater management.21 A report by the Natural Resources Defense
Council reviewing published research on the benefits to owners of commercial buildings that
incorporate well-designed green infrastructure found that they can command higher rents and
property values, increase retail sales, save energy, reduce maintenance costs, reduce flood
damage costs, reduce water bills, lower crime, and improve health and job satisfaction for
employees.22
Maintenance cost comparisons have also shown that green infrastructure practices can be less
expensive than conventional gray infrastructure, although more research is needed to help
communities make informed decisions based on their particular context and the types of green
infrastructure approaches used.23 Green infrastructure approaches have not been used as
extensively or as long as gray infrastructure for stormwater management, so actual operations
and maintenance costs are not as well documented. However, EPA and the Water Environment
Research Foundation developed a set of spreadsheet tools to help users calculate capital and
long-term maintenance costs for several green infrastructure practices, including retention
ponds, permeable pavement, and green roofs.24
Tools are also available to help communities evaluate the potential cost savings and economic
benefits of green infrastructure. For example, the Center for Neighborhood Technology and
American Rivers developed a method to evaluate the economic, environmental, and social
benefits of green infrastructure.25 Their guide includes examples illustrating the potential
economic and nonmonetary value of multiple benefits, including reduced water treatment needs,
increased ground water recharge, and improved neighborhood aesthetics. The Center for

II. Strategies That Support Sustainable Communities and
Green Infrastructure
While storm sewers and other types of gray infrastructure are built below ground, much of
green infrastructure is visible at the ground level. Sustainable communities that fully integrate
green infrastructure approaches use community design to help simultaneously achieve
environmental, economic, and social goals. These goals include improving water quality,
revitalizing neighborhoods, reducing flood risk, and providing recreational areas that
encourage physical activity. Community planners can enhance these and other benefits by
selecting the types and locations of green infrastructure approaches that best support their
goals.
Communities need to be particularly thoughtful when applying green infrastructure in areas
where space is most valuable, such as in compact neighborhoods—the very places where past
development has contributed to serious water quality problems. Many older cities and towns
face serious challenges in better managing stormwater to improve water quality, address
overflows from combined storm and sanitary sewer systems, and reduce flooding. Green
infrastructure could help address these problems, but the cobenefits would be greatest if
designers selected practices that also achieve other community goals. For example, wide
sidewalks with space for outdoor cafes, bike racks, benches, and other amenities attract people
to a neighborhood, bringing customers to businesses. Downtowns might, therefore, look for
green infrastructure practices that do not compete with these amenities for valuable sidewalk
space. For example, street trees can be planted in tree boxes that hold soil and water
underneath sidewalks made with permeable paving, allowing stormwater to infiltrate and
keeping the trees healthy without encroaching on the area where people walk. Designers can
often accommodate green infrastructure in the existing street width by, for example, extending
curbs into the no-parking zone at intersections to both create space for a rain garden to absorb
stormwater and shorten the distance needed to walk across the street (see Exhibit 1 4). These
curb extensions also help calm traffic and protect walkers and bicyclists. Other factors for
designers to consider when selecting green infrastructure practices to support sustainable
communities include how well they enhance the aesthetics of public spaces and create a sense
of place and whether they are compatible with compact development that puts homes and
workplaces near transit stations.

options for addressing flooding and water quality problems in a nearly 1 00 percent impervious
commercial corridor where development activity is concentrated.28 The city's evaluation
revealed that if individual property owners were responsible for managing their stormwater on-
site, development density would tend to decrease. Further, the city found that dispersed
management responsibilities could jeopardize the long-term effectiveness of this approach.
However, a regional facility located in a low-value area could treat stormwater using
bioinfiltration and detain storm events to reduce downstream flooding while leaving
1 00 percent of the commercial district available for redevelopment. The city could acquire land
for the facility by establishing a stormwater district through which property owners would be
able to spread out the costs of constructing the facility.
The following strategies illustrate how green infrastructure can enhance sustainable
communities' approaches and help achieve a wide range of goals, including to:
A. Preserve and Restore Open Space, Natural Beauty, and Critical Environmental Areas.
B. Create Parks, Community Gardens, and Other Public
Green Spaces.
C. Direct Development Toward Existing Communities.
D. Create Compact, Mixed-Use Development.
E. Build Neighborhood Streets and Trails That Encourage Walking and Biking.
F. Cultivate Communities with a Strong Sense of Place.
G. Encourage Community and Stakeholder Collaboration in Development Decisions.
H. Promote Green Building Practices.
A. Preserve and Restore Open Space, Natural Beauty, and Critical
Environmental Areas
Forests, wetlands, and other natural areas provide recreational space, shape regional identity,
and support regional economies through tourism, agriculture, and other activities. In addition,
protecting natural areas is often the least expensive, most efficient way to keep stormwater
pollution from further degrading waterways. Natural areas serve a wealth of ecological
functions that cannot be easily replaced. For example, wetlands can absorb floodwaters and
buffer storm surges, protecting communities from flooding while performing ecological

services like providing wildlife habitat and filtering excess nutrients and contaminants from
stormwater. During Hurricane Sandy, communities with healthy dune systems had natural
buffers that protected adjacent neighborhoods, while communities without healthy dunes
generally suffered more damage.29 The city of Crystal Lake, Illinois, created a green
infrastructure plan that established the priority areas of the city for protection, including highly
important resource areas such as river corridors and watersheds that are critical for the city's
environmental health and economic vitality and secondary resource areas that could serve as
important connectors in a green network.30 The plan's benefits include reduced flooding,
conservation of wildlife habitat and biodiversity, reduced infrastructure costs, and a stronger
sense of place and community identity. Saratoga PLAN, a nonprofit land trust in Saratoga
Springs, New York, created a toolkit for municipalities considering voluntary, incentive-based,
and regulatory strategies to preserve open lands, including conservation easements, the
purchase of development rights, and zoning.31
B. Create Parks, Community Gardens, and Other Public
Green Spaces
Parks, community gardens, and other public green spaces create opportunities in built-up areas
for people to gather, exercise, and connect with nature. These spaces are particularly important
in low-income and disadvantaged neighborhoods because they provide critical health, social,
and environmental benefits. These types of places can also readily incorporate green
infrastructure into their design.
The Chicago region's comprehensive plan CO TO 2040 recommends investing in increasing the
supply of urban parks, protecting the region's most critical natural areas, and creating a
network that links the region's green spaces.32 The Chicago Metropolitan Agency for Planning,
the regional planning organization, recognized that having these places helps make the
Chicago area a healthier and better place to live and work, attracting residents and employees
and improving economic competitiveness. Low-income communities in the region do not have
enough parks for their residents, and one of CO TO 2040's recommendations was for the

Millennium Park is a 2.5-acre rooftop garden on top of a parking

C. Direct Development Toward Existing Communities
Investing in existing communities brings jobs and services for residents and takes advantage of
past infrastructure investments. Redevelopment also spurs cleanup of historical environmental
and health hazards at contaminated properties that often disproportionately affect
disadvantaged populations. These actions can revitalize areas that have suffered from
disinvestment, replacing underused or vacant lands with productive businesses, parks, and
other community amenities. Very low levels of impervious cover have been shown to degrade
watershed health.34 Developing compactly on a redevelopment site can avoid creating new
impervious surfaces that could further degrade water quality.
For example, the city of Buffalo, New York, started a program through which the city clears
vacant lots to make way for rain gardens and other green infrastructure that can help improve
property values and provide neighborhood parks and green space while helping the city meet

techniques to manage
stormwater that can allow
additional development in the
city's Old Town while preserving
its character.36 Improving Old
Town's infrastructure will ensure
that the city can accommodate
development downtown where it
has the least impact on natural
areas and the greatest economic
benefits.

garden in Buffalo was built with the help of Grassroots Gardens,
an organization dedicated to helping residents create and sustain
community gardens on vacant properties in the city. Several
entities, including churches, community centers, and nonprofit
organizations, help maintain it.
D. Create Compact, Mixed-Use Development
Compact, mixed-use development puts buildings close together, creating neighborhoods
where residents are near shops, restaurants, and services; public transit, walking, and biking
are viable transportation options; and jobs are easily accessible. Strategies include constructing
buildings with a mix of uses such as retail on the ground floor and offices or apartments above;
reducing (or eliminating) the distance between buildings; positioning buildings closer to the
street; rightsizing surface parking to meet demand while minimizing the amount of developable
land it uses; and narrowing road lanes where feasible. These approaches help make a
neighborhood more walkable by reducing distances between destinations and calming traffic.
They also minimize the amount of land and impervious surface that is necessary for a given

unit of development, leaving more land undeveloped and able to continue to absorb rainwater
and perform other ecological functions. Compact building design can be one of the most cost-
effective ways to prevent additional stormwater pollution because it requires no construction or
maintenance beyond what is already occurring.
The city of Chicago's comprehensive plan, Adding Creen to Urban Design, recognizes that the
city's use of resources is much more efficient than would be the case if the population were
more spread out, requiring more roads and other impervious area, using more energy to
operate water and wastewater infrastructure, and necessitating driving greater distances.37 In
other words, the compactness of the city is a necessary and important strategy for achieving
many of its environmental goals, including improving water quality, reducing energy use, and
lowering greenhouse gas emissions. Likewise, Ranson, West Virginia, established compact
development as a stormwater best management practice in its 2012 comprehensive plan,
recognizing that land left undeveloped is one of the most valuable and cost-effective ways to
prevent additional stormwater pollution.38
E. Build Neighborhood Streets and Trails That Encourage Walking
and Biking
Walkable neighborhoods have streets, sidewalks, and paths that are safe and appealing for
pedestrians and bicyclists. Streets designed for the safety of all users are also known as
"complete streets," which can encourage residents to lead healthier lifestyles. Green
infrastructure plays an important role in designing streets to make a neighborhood walkable.
Street trees provide shade, filter airborne pollutants, and help reduce ambient air temperatures,
making walking outdoors in hot weather more comfortable. In general, adding greenery, such
as a vegetated buffer between people and traffic, can also help to make the area feel more
inviting. Walking and biking trails can be designed as linear community parks that link
destinations, create opportunities to get around without a car, improve public health by
encouraging physical activity, integrate green infrastructure throughout a community, and
provide green space in underserved neighborhoods.
Roads designed primarily for automobiles are wider and tend to encourage single-story
development with large areas of surface parking. All of this impervious area creates more

stormwater runoff. Although site-scale
green infrastructure practices can help
such places improve stormwater
management, they cannot readily replace
the full range of ecological functions
provided by natural areas. Taking into
consideration opportunities to limit
impervious surfaces and preserve or
restore natural areas by planning for
green infrastructure across an entire
neighborhood, town, or city can lead to
more effective stormwater management
and help maximize the other benefits of
green infrastructure.
The city of Maplewood, Minnesota,
adopted a living streets policy framework,
under which the city will rebuild streets
after infrastructure upgrades to better
accommodate walkers, bikers, and transit
users while incorporating green infrastructure such as trees and rain gardens on street edges.39
The plan helps the city turn the need to replace aging drinking water and wastewater
infrastructure into an opportunity to improve streets. The city can save money by achieving
multiple goals, including improving safety and environmental quality, with a single project.
F. Cultivate Communities with a Strong Sense of Place
Development that represents the values, history, culture, economy, and geography of a
community is key to supporting a strong economy, vibrant neighborhoods, and a high quality
of life. Green infrastructure approaches can help create vibrant, interesting neighborhoods with
a strong sense of place—a unique combination of characteristics that makes a place special.
Many green infrastructure approaches use plants adapted to each region's climate, helping to
create a distinct identity and contribute to a neighborhood's overall aesthetic appeal, while gray

infrastructure is almost entirely underground where it is out of sight and out of mind. Public art
and green infrastructure can be integrated into a single site, each reinforcing the sense of place
established by the other. Features such as fountains fed by rain water, living walls, or artist-
designed stormwater infrastructure can help enliven a space and educate visitors about ways to
protect water quality (see Exhibit 1 7).
The city of St. Paul, Minnesota, studied how public art could be integrated into green
infrastructure along the city's 11 -mile light rail line to manage stormwater, catalyze and
support transit-oriented development, and provide benefits to all residents. The city collected
examples from across the country that demonstrate community enhancements and could serve
as models for its own projects (see Exhibit 1 I).40
In rural regions, vegetated areas such as forests, wetlands, grasslands, and working farms often
shape the region's sense of place. Protecting and conserving these areas by directing
development to existing neighborhoods and employment centers can help maintain the
character that attracts tourism and supports the quality of life residents value while protecting
valuable water resources. For example, Saratoga County, New York, developed a green
infrastructure plan to safeguard and expand its network of parks, recreational trails, open

spaces, working lands, and protected areas to maintain the county's character and support its
continued economic prosperity.41
G. Encourage Community and Stakeholder Collaboration in
Development Decisions
Sustainable communities strategies involve residents, business owners, community-based
organizations, and other stakeholders early and often to define and implement the community's
vision and goals. Likewise, because green infrastructure can help transform how a community
looks and functions, public involvement in the planning process is equally important.
Community leaders might need to adapt outreach efforts to reach populations that are
disadvantaged, vulnerable to displacement, and often left out of development decisions.
Engaging all stakeholders early in the planning process can create needed support and help
form partnerships that maintain momentum for the plan during a long implementation period.
Watershed Watch in Kentucky, Inc., a statewide organization dedicated to improving water
quality, developed a plan to help communities adopt green infrastructure approaches by
empowering individuals to take action through "citizen action plan teams."42 Strategies it
suggests to help residents influence local decisions about stormwater management include
assessing what information resources are available; identifying applicable laws, ordinances, and
regulations; coordinating planning with other interested stakeholders; identifying funding
opportunities; and monitoring green infrastructure performance.
H. Promote Green Building Practices
The term "green building" refers to the practice of creating structures and using processes that
are environmentally responsible and resource-efficient throughout a building's life-cycle from
siting to design, construction, operation, maintenance, renovation, and deconstruction. An
important aspect of green building is designing sites and structures to allow the capture, use,
infiltration, or evapotranspiration of stormwater to reduce some of development's negative
effects on water quality. Many green building certification programs look beyond the building
envelope to techniques for environmentally sustainable stormwater management such as green

roofs, cisterns, and site-scale green infrastructure.43 These approaches can have many benefits,
including reducing stormwater runoff and storing water for landscaping and other nonpotable
uses, which is particularly important in regions where water is scarce or is projected to become
scarcer due to climate change.
In Redmond, Washington, the Green Building and Green Infrastructure Incentive Program
encourages developers and homebuilders to incorporate green building and site-scale green
infrastructure techniques into new residential developments. Techniques include retaining
native vegetation, reducing impervious surface area, collecting rainwater from roofs for
nonpotable uses, using pervious materials, and installing green roofs. Incentives include
priority building permit processing, reductions in the required minimum lot size, and additions
to allowed density.44

I. Organizing Stakeholders
The strategies that support sustainable communities and green infrastructure are diverse and
touch on many aspects of a community. A variety of stakeholders can directly implement or
indirectly support these strategies, and organizing these stakeholders is an important step for
an organized and inclusive process. This section discusses:
A. Who can take the lead?
B. Which government entities need to be involved?
C. Which community members need to be involved?
D. How can the federal government help?
A. Identifying Lead Stakeholders
Every community needs an individual, organization, or entity to take the lead in developing a
sustainable communities and green infrastructure plan—a local champion committed to
improving a neighborhood, city, or region's quality of life and sustainability. Most successful
plans involve many stakeholders, and coordination is important so that everyone understands
how individual activities fit into the overall framework that moves the community forward. In
many communities, a local government agency takes the lead in organizing stakeholders and
developing the green infrastructure plan because it will help that agency serve its core mission.
Other times, stakeholders have coordinated broad-ranging community visioning exercises and
developed plans. For example, in Pittsburgh, Pennsylvania, a nonprofit, community-based
development organization took the lead in developing the East Liberty Green Vision, a plan for
integrating green features into public and private development in the East Liberty neighborhood.
Two private foundations and the Pennsylvania Department of Conservation and Natural
Resources funded the effort.45 In Detroit, the Lower Eastside Action Plan began as a
conversation among community development organizations serving neighborhoods in the
southeastern part of the city. The organizations collaborated with a diverse group of other
stakeholders to develop a 1 0-year vision for the area that aims to stabilize neighborhood
property values, improve stormwater management, and benefit the city as a whole by

repurposing vacant land for urban gardening, forest regeneration, greenway development, and
other uses.46
B. Involving Government Entities
Although a variety of entities can spearhead successful sustainable communities and green
infrastructure plans, participation and support from local government is crucial. Local
governments manage not only publicly owned land but also streets, parking lots, and other
places that often accommodate
green infrastructure. If local
governments lead by example
by using green infrastructure
approaches on public land,
private property owners can
see and learn about these
techniques and might be more
likely to adopt them. Local
governments can also ensure
that policies and programs are
consistent with the
community's vision, and the
city's demonstrated leadership
and commitment to the plan
objectives help keep
stakeholders engaged. The
most appropriate government
players will vary but often
include:
The mayor and other elected leaders.
City departments, including the departments of planning, transportation, housing,
public works, parks and recreation, economic development, engineering, and the
environment.
Leadership and staff from adjacent jurisdictions.

Oregon. The Portland Bureaus of Environmental Services and
Transportation worked with the Regional Arts and Culture Council to

Organizing Stakeholders
• State and county government agencies.
• Federal government agencies that control land in the community such as the National
Park Service and the U.S. Forest Service.
• Quasi-government partners, for example, water, sewer, and stormwater utilities;
regional councils; development authorities; and school districts.
Each of these entities has a different interest and role in the process, and including a broad
range of stakeholders will help ensure that the team can get early buy-in from important
participants and explore a range of opportunities. For example, school districts might own
large properties, including some that are no longer in use, that could be locations for pilot
projects to evaluate the effectiveness of different green infrastructure strategies and provide a
venue for environmental education. The water utility might be able to help set realistic
expectations about service costs under different development scenarios that would provide
important information for community planning.
C. Involving Community Members
It might take years for a community to fully implement a sustainable communities and green
infrastructure plan, so early and ongoing involvement of stakeholders throughout the
community is important to maintain enthusiasm and momentum. In addition, because private
property owners are often responsible for maintaining site-scale green infrastructure practices
on their sites, they must understand how they work and appreciate their value. Participants will
vary, but successful sustainable communities and green infrastructure plans often involve:
• Residents, including people from underserved communities that often have the least
green space in their neighborhoods.47
• Property owners, developers, and homeowner associations.
• Neighborhood groups such as garden clubs and civic improvement organizations.
• Business organizations such as the local chamber of commerce.
• Nonprofit organizations such as watershed groups, environmental justice organizations,
and faith-based institutions.
• Academic and health institutions such as universities and hospitals.

Partnerships with the private sector, academic institutions, nonprofit organizations, and private
foundations help local government make limited resources go further. These partnerships can
help the other organizations in various ways. For example, universities could help with ongoing
performance monitoring to improve scientific understanding of best practices for local
conditions and provide real-world training for students. The University of Wisconsin-Madison's
Department of Urban and Regional Planning offers a course for graduate students that provides
practical training in planning. In 201 0, the program worked with the city of Freeport, Illinois, to
help the city use green infrastructure planning to reduce flooding, make neighborhoods more
attractive, revitalize downtown, create jobs, and clean up contaminated properties so they could
be developed into assets for the community.50

IV. Developing a Sustainable Communities and Green
Infrastructure Plan
To most effectively attain the benefits of green infrastructure, it is important for stakeholders to
develop a good plan of action that can transform a community vision into reality. Specific
components of the plan will vary from place to place, but plan developers should consider
several steps that can help the plan succeed in the long term, including:
A. Developing a community vision.
B. Establishing goals.
C. Assessing assets and opportunities.
D. Identifying potential approaches to add green infrastructure and help create sustainable
communities.
E. Factoring brownfields and hazardous waste sites into planning.
F. Developing strategies for funding.
G. Monitoring and measuring progress.
H. Planning for long-term operations and maintenance.
I. Identifying federal government resources.
A. Developing a Community Vision
Green infrastructure is an important component of many types of local plans at the
neighborhood, city, and regional levels, including those for water resource management,
hazard mitigation, climate adaptation and resilience, sustainability, environmental justice, and
economic development. However, many communities are also developing stand-alone green
infrastructure plans that complement other efforts. Whether green infrastructure is one aspect
of a broader plan or is the central purpose of a plan, and whether the plan focuses on a
neighborhood or an entire region, the first step in a planning effort is typically developing a
vision for what the community will look like once the plan is fully implemented. The vision
brings people together to determine a common view of the future and guides the plan and its
implementation.
One benefit of green infrastructure is that people can usually see and enjoy it, often right in
their front yard, on their building's roof, and in their neighborhood streets and parks. Green
infrastructure affects the look and feel of a neighborhood—usually for the better—but people
are more likely to be happy with the results if they had a hand in deciding where it will be and
what it will look like.
27
-------
Developing a Plan
Community goals and
values can affect the
alternatives that property
owners or local
governments consider and
influence how they weigh
factors for selecting among
options. For example, a
neighborhood with a strong
artist community could
have artist-designed
downspouts, rain barrels,
or planter boxes, which can
foster support for green
infrastructure and long-
term stewardship among
residents. The Whitefish Bay
Civic Foundation in
Whitefish Bay, Wisconsin,
sponsored a rain barrel art project in which local businesses exhibited artist-designed rain
barrels that were then auctioned off to residents.53
Meaningful stakeholder involvement from the outset will help ensure that the community's
vision effectively incorporates local knowledge, experience, and insight. Developing a vision for
widespread implementation of sustainable communities approaches and green infrastructure
has other benefits, including:
• Encourages private investment consistent with the vision. Private-sector entities that
initiate and finance the bulk of new investment in the community, including property
owners, developers, investors, and businesses, will have a guide to understand the
community's expectations and preferences for future development.
• Garners broad-based support. Individuals, businesses, and organizations such as
neighborhood groups, nonprofits, schools, health care institutions, and foundations can

Developing a Plan
be inspired and encouraged to participate in implementing the vision when the
community can clearly demonstrate its support.
• Leads to supportive policies and programs. Local governments can use the vision to
guide development of policies, regulations, capital improvement plans, incentive
structures, city department budget priorities, development review and approval
procedures, and other programs that help implement the vision.
• Builds support for public expenditures to manage stormwater. Educating the community
about the cost of needed infrastructure repairs or upgrades requires significant,
ongoing public engagement. The public is more likely to support government spending
on green infrastructure, as well as possible tax increases or higher utility rates and fees
should they be necessary, if they understand and support the longer-term investment
plan and its benefits. Once plan implementation begins, the green infrastructure itself
allows property owners to see the benefits of the investment of public money.
• Enables better coordination of efforts. Articulating how the vision supports multiple
community goals can encourage collaboration across organizations and local
government agencies with different missions. The most successful green infrastructure
plans identify connections to other ongoing efforts, such as those promoting economic
development, preparation for climate change impacts, and environmental sustainability,
to help identify the most impactful projects.54
B. Establishing Goals
In many communities, the initial impetus for developing a sustainable communities and green
infrastructure plan might be to manage stormwater and improve water quality, and the plan's
goals would naturally include improvement in indicators of watershed health. For example, the
primary goal might be to eliminate combined sewer overflows or to have water clean enough to
allow fishing or swimming in the community's rivers, lakes, and beaches.
However, regardless of the initial reason for developing a sustainable communities and green

Developing a Plan
might also explicitly set goals like fostering community pride through signs of new investment
in the community—visible results that can make community members want to join in the
revitalization. Goals will vary depending on the community's characteristics, such as whether it
is growing or losing population; whether it has combined or separate storm and sanitary
sewers; and whether it is rural, suburban, or urban. This community context helps create
specific, feasible strategies to implement the plan.
Fort Campbell, Kentucky, created a green infrastructure plan with the primary goal of improving
the personal resiliency and health of soldiers and their families.55 The plan aims to ensure that
residents can get to community facilities without having to use a car so they can get the
physical and mental health benefits associated with exercise and time spent outdoors. The plan
recognizes improved stormwater management and environmental sustainability as valuable
cobenefits.
The Wasatch Front Regional Council in Utah led a collaborative effort to create (Re)Connect, a
green infrastructure plan to complement its regional plan for development and transportation,
Wasatch Choice for 2040. One of the first steps in developing (ReJConnectwas to identify goals
for the process itself, including:
• "Increase public support and awareness regarding the benefits of a green
infrastructure approach and an interconnected green infrastructure network.
• Collaboratively map an interconnected network by identifying and prioritizing the
region's existing green infrastructure assets and resources.
• Identify existing green infrastructure lands and propose objectives and strategies to
plan, design, and manage the region's green infrastructure network.
• Bring together local and regional stakeholders that play a part in planning,
engineering, studying, managing, and maintaining green infrastructure.
• Support an interconnected green infrastructure network in order to provide environmental,
social, recreational, psychological, public health, and economic benefits.
• Encourage the incorporation of green infrastructure planning and implementation
strategies into existing plans and studies."56

gray infrastructure. Integrated planning for gray and green infrastructure can allow

potentially reduce the amount of gray
infrastructure needed to meet water quality
objectives cost-effectively and on schedule. EPA compiled case studies of public entities that
have evaluated the economic impacts of their green infrastructure programs to help
communities understand the potential benefits of their own programs, and it highlights several
cases where green infrastructure, in combination with gray infrastructure, can reduce costs.57
C. Assessing Assets and Opportunities
Planning for sustainable communities and green infrastructure involves assessing the
community's existing assets and opportunities. The features the community inventories and
maps will vary depending on the community's goals, but many communities collect data on:
• The amount of impervious surface.
• The number and/or amount of roads, parking lots, and buildings that could incorporate
green infrastructure.
• Land ownership and use, including vacant and contaminated properties.
• Existing green space and trails.
• Watershed boundaries.
• Condition of water bodies.
• Areas at risk of flooding.
• Rainfall amounts and patterns, soil type, topography, depth to ground water, and other
factors that affect green infrastructure design and functionality.
This information can help communities select the most appropriate sites for green
infrastructure and design the most effective green infrastructure solutions for particular sites.

-------
Developing a Plan
One useful tool for analysis is EPA's National Stormwater Calculator, which estimates the
amount of stormwater runoff from a site and how runoff volumes could change with the use of
a given site-scale green infrastructure technique based on local soil conditions, land use, and
historical and projected precipitation patterns.58
Analysis of economic conditions and population demographics can help identify areas where
the economic and social benefits of sustainable community and green infrastructure
approaches could have the most impact, including areas where residents might be vulnerable to
displacement. This information can help community planners address the specific needs of
vulnerable populations as areas are revitalized. It can also serve as a baseline against which the
community can measure changes over time.
The development of the Milwaukee Metropolitan Sewerage District's Regional Creen
Infrastructure Plan involved analysis of impervious area, soils, land use, property ownership,
ground water, topography, separate and combined sewer areas, tree canopy, and other data.
This analysis allowed the district to estimate the storage volume that new green infrastructure
could accommodate and how much it would cost to install and maintain.59
D. Identifying Potential Approaches to Add Green Infrastructure
In developing an overall plan, stakeholders need to identify a variety of approaches and
opportunities to incorporate green infrastructure into their community—on both public and
private land, using both incentives and requirements. These approaches can fall into one of
four categories:
1. Use existing public land.
2. Acquire additional public land.
3. Provide incentives for implementing green infrastructure on private land.
4. Require green infrastructure on private land.
1. Use Existing Public Land
Local governments can build support for a green infrastructure plan when they lead by example.
For example, at the larger scale, local governments sometimes control sizable, contiguous
areas of natural land whose preservation maintains community character and sustains vital

ecological functions. At the site scale, green infrastructure projects in public spaces can achieve
multiple benefits, including:
• Providing opportunities to educate people about the problems of poorly managed
stormwater and potential solutions.
• Demonstrating the aesthetic and other values of green infrastructure to build public
support.
• Providing opportunities to collect performance and cost data and learn about local
challenges to implementation.
• Developing maintenance schedules and protocols that private property owners can use.
• Creating a demand for workers who can install and maintain green infrastructure.
Most importantly, green infrastructure on public land sends a clear message to other
community stakeholders that the local government is committed to the green infrastructure
plan. A demonstrated commitment by the local government is often critical to getting the
private sector to invest in the plan as well.
Many routine local government activities
could integrate site-scale green infrastructure
practices. For example, a community could Gree" infrastructure on public land

Adding green infrastructure elements to these
projects during project planning would have little or even no additional cost. The city of Tucson,
Arizona, created a green streets policy that requires all publicly funded road construction and
reconstruction projects to incorporate green infrastructure that can capture and absorb the first
quarter-inch of rain.60 The city is applying this policy not just for water quality benefits, but
also to ensure that trees are added to streets in lower-income communities. Milwaukee's Creen
Streets Stormwater Management Plan helps the city select appropriate strategies for planned

of green infrastructure. In addition, the New York City Departments of Environmental Protection,

establish responsibilities and improve coordination for site-scale green infrastructure in public

Developing a Plan
Exhibit 1 5: Using Vacant Property for Green Infrastructure
Some communities are struggling to manage a large number of vacant lots and abandoned buildings that
are waiting for demolition because the market currently does not support redeveloping the land. Some of
these communities have recognized that if they use a vacant property for green infrastructure, they could
remove a source of blight, reduce stormwater pollution, provide a community amenity, and spur interest
in redevelopment. In short, green infrastructure could help convert vacant property from a liability to an
asset.
The obstacles to creating a vacant lot program for green infrastructure can be difficult for municipalities
to overcome. Many vacant properties are privately owned, so local governments have to acquire them
outright or acquire an easement for their use. However, land banks or other mechanisms for acquiring
and holding property are often not available or can be time consuming and labor intensive to use. The
community needs to determine which properties it should acquire to get the size and location of green
infrastructure that will produce the most public benefit, an approach that generally requires a public
process and engineering consultations. Property might also be contaminated with hazardous substances
and need to be evaluated and/or cleaned up. Finally, the community will need a strategy to fund and
maintain the green infrastructure. Although all green infrastructure on public land needs funding and
maintenance, the costs can be a particular burden in a distressed community struggling with a vacant
property problem.
The New York City Soil & Water Conservation District evaluated several successful and early-stage
programs. They found several lessons for communities hoping to remedy a vacant lot problem through
green infrastructure, including:
• Water agencies can be valuable long-term partners because programs often address stormwater
management.
• Successful programs have multiple goals in addition to stormwater management. Sometimes the
design and use of new green space is a compromise between what is ideal for stormwater
management and what the community will embrace and support.
• Spatial analysis on the regional, watershed, and subwatershed scales; stakeholder input; and site
visits are all important when selecting properties to acquire.
• Communities often establish a separate program for green infrastructure on vacant property because
the goals of the program often span multiple agencies or offices without fitting neatly into any one,
and the programs generally require a unique combination of expertise and dedicated staff.
• Programs have different acquisition strategies, financing tools, ownership structures, and
maintenance programs (often a combination of them). No one approach works best in all
circumstances.

Developing a Plan
Incorporating green infrastructure into sustainable communities approaches can transform
neighborhoods. In Nashville, Tennessee, the city remade the street connecting the Metro
Courthouse and the state capitol using a variety of green infrastructure practices, including
shade trees, bioswales, and permeable sidewalk paving. The city's efforts not only reduced
stormwater runoff by more than 1 million gallons per year but also revitalized a formerly
dilapidated part of the city, attracting more pedestrians and investment in new businesses and
restaurants.65'66 In Minneapolis, the redevelopment of former public housing projects into a
900-unit, mixed-use neighborhood used open spaces and site-scale green infrastructure
woven throughout a series of parks to manage stormwater and create attractive new
recreational amenities for residents.67'68
2. Acquire Additional Public Land
The local government could strategically acquire land in areas where green infrastructure could
provide the greatest benefits for water quality, community revitalization, or other goals. In
some cases, particularly in communities that have seen significant population declines,
acquiring vacant land for green infrastructure can stabilize property values and allow the local
government to assemble land best suited for open space or green infrastructure approaches
that can manage stormwater from several surrounding properties. Given the power of such
efforts to transform entire communities, early and ongoing engagement of residents in affected
neighborhoods is critical.
Milwaukee developed the Greenseams Program to acquire outright or purchase conservation
easements69 for the conservation or restoration of land along streams, shorelines, and wetlands
and in areas that serve critical water storage functions and are subject to development
pressure.70 Between 2001 and 201 2, the program purchased 2,500 acres of land and restored

500 acres of forest, prairie, or wetlands.71 In 201 0, the mayor of Detroit assembled a steering
committee consisting of business, nonprofit, government, and philanthropic stakeholders for
long-range planning. The committee developed a vision for the city's future that recommended
assembling large, contiguous tracts of land for new public open space that could manage
stormwater and provide other community amenities like parks and community gardens.72 In
addition, the steering committee recommended that the city acquire some vacant lots to
provide open space for parks, forest, and greenways to help stabilize neighborhood property
values and encourage redevelopment. One community plan the city is considering to inform
citywide planning efforts is the Lower Eastside Action Plan, which was put together by a group
of individuals and organizations in the neighborhood. The plan identifies larger, contiguous,
and ecologically valuable areas that could be managed as natural lands; areas that could be
used for large-scale stormwater facilities; and areas that would benefit from additional
parkland.73
3. Provide Incentives for Implementing Green Infrastructure on Private Land
Many strategic locations for green infrastructure will be on privately owned land, so private-
sector involvement will be necessary to implement an effective, comprehensive green
infrastructure plan. Communities can encourage private property owners to participate in the
community visioning process so they have a stake in its implementation. Beyond that critical
step, communities across the country have developed many innovative programs to encourage
private-sector participation.74
Beginning in 2006, the city of Portland, Oregon, allowed developers to build higher-density
buildings in the central city area than otherwise allowed under zoning codes if they installed a
green roof. The amount of additional developed space allowed on a building's footprint is
determined by the percentage of the footprint that the green roof covers.75'76 As of 2008,
developers participating in the program had installed 260,000 square feet (6 acres) of green

roofs, creating an additional 600,000
square feet of development that
would not have been otherwise
permitted.77 The city of Chicago
offers another type of incentive,
offering developers an expedited
permit process and reductions in
building permit fees if they include
site-scale green infrastructure and
other environmentally sustainable
building designs, including solar
panels and geothermal systems.78
Many municipalities discount
stormwater utility fees as an
incentive to install certain green
infrastructure practices. Minneapolis
offers a credit of up to 50 percent off the stormwater utility fee for practices that reduce
stormwater volume or filter out pollutants, such as rain gardens, vegetated swales, and green
roofs. The city offers credits of up to 1 00 percent for practices that can accommodate on-site
stormwater from a 1 00-year storm event.79'80
Communities also use other types of financial incentives. In 2008, New York City passed a
measure to allow a one-year property tax abatement of up to $4.50 per square foot for
buildings with green roofs.81 Philadelphia's Stormwater Management Incentives Program offers
low-interest loans of $75,000 to $1 million to non-residential property owners to implement
certain green infrastructure practices.82

Developing a Plan
Education can also encourage property owners to use green infrastructure approaches.
Education can include creating demonstration projects, publishing technical design materials,
creating outreach materials, and offering technical assistance programs. Communities should
make sure that their educational materials are understandable to people of all education levels
and backgrounds, which generally means using plain language and perhaps translating
materials into multiple languages.83 Oklahoma City developed a Green Infrastructure Education
Program that created opportunities for local professionals to share their expertise with others
in the community through a speaker series.84
EPA and academic researchers studied the potential to reduce stormwater volume using a reverse
auction, in which homeowners are asked to bid for the amount they would need to be paid to
participate in the program and install stormwater controls on their property. The study found that
55 percent of homeowners that participated in the program were willing to do so without any
financial incentive, demonstrating the potential for an education campaign to encourage action.85
In addition, it found that compared to paying homeowners a flat fee for installing stormwater
controls on their property, a reverse auction mechanism was a more cost-effective way to reduce
stormwater volume. Communities might want to experiment with innovative programs like this
one to see what works best to encourage private landowners to participate.
Award and recognition programs are another low-cost way to encourage property owners to
implement green infrastructure approaches. For example, the nonprofit organization Lake
Champlain International has a certification program for residential properties in the Lake
Champlain watershed in Vermont that reduce stormwater runoff.86 Washington, D.C., sponsored
a Green Infrastructure Challenge, inviting applicants to design innovative green infrastructure
solutions for selected sites.87 DC Water awarded $1 million for the design and construction of
the winning proposals. To help communities host design competitions, the Water Environment

4. Change Requirements for Private Land
Municipalities can change their codes and regulations to require stormwater to be effectively
managed on the site where it falls or as near to that site as practical. Stormwater regulations
are the most direct means to achieve this goal. In addition, regulations can help make sure that
green infrastructure is implemented when it is most cost effective to do so—at the time of
initial site planning for both new and redevelopment projects. Many municipalities are investing
significant resources to correct existing problems by retrofitting areas to incorporate green
infrastructure and reduce the amount of stormwater runoff generated by development (see
Exhibits 1 2, Exhibit 1 4, and Exhibit 20). If every new development project increases the amount
of stormwater that the gray
infrastructure system must handle,
the community will need more
expensive retrofits of existing
development to avoid further
degrading water quality. Stormwater
regulations can, therefore, be an
important tool to control overall
costs for mitigating stormwater
runoff.
In 201 1, the city of San Jose,
California, approved a stormwater
management policy that establishes
specific requirements to control
stormwater runoff from new
development and redevelopment
projects.89 The policy requires
developers to minimize runoff

Developing a Plan
through site design decisions that minimize impervious cover and protect natural areas and to
treat stormwater with site-scale green infrastructure.
Stormwater regulations generally apply to individual sites, so they cannot address larger land
use practices and development patterns. In most communities, other municipal codes and
regulations, including parking requirements, street design standards, and zoning ordinances,
are important complements to stormwater regulations because they help determine the amount
of impervious cover. For example, most communities have minimum parking requirements for
development. The more parking required, the more impervious surface is created.
Oversupplying parking also often reduces space for pedestrian amenities or forces pedestrians
to cross large parking lots, which can discourage walking. By contrast, mixed-use
neighborhoods generally need less parking because facilities that have different peak usage
patterns can share parking spaces, and people can get around easily without a personal vehicle.
As a result, these neighborhoods can often reduce or even eliminate parking minimums, which
can reduce the amount of impervious surface—and give developers more flexibility in how they
use their land.90
EPA developed a Water Quality Scorecard'to help local governments identify opportunities to
remove barriers and revise or create codes, ordinances, and incentives to better protect water
quality.91 The tool covers ways to protect natural resources (including trees) and open space;
promote efficient, compact development patterns and infill; design streets that reduce overall
imperviousness and create safer conditions for walkers and bicyclists; encourage efficient
parking; and adopt green infrastructure stormwater management provisions. EPA also has a
Sustainable Design and Creen Building Toolkit for Local Governments that helps local
governments evaluate codes and ordinances that affect the design, construction, renovation,
and operation and maintenance of a building and its immediate site to ensure that they allow
sustainable design and green building practices.92

Developing a Plan
E. Factoring Brownfields and Hazardous Waste Sites Into Planning
Past industrial and commercial activity has left a legacy of soil and water pollution at sites
across the country. Thousands of potentially contaminated properties, or brownfields, are
located in densely populated neighborhoods, often near places where residents gather and
children play. When cleaned up, brownfields and hazardous waste sites can become attractive
locations for green infrastructure, which can help convert a neighborhood liability into an asset
for the community. Repurposed, cleaned up brownfields and hazardous waste sites improve the
value of neighboring properties,93 help to
revitalize entire neighborhoods, and take
advantage of the surrounding
development's existing infrastructure.
Nevertheless, using green infrastructure
on potentially contaminated sites requires
careful planning to avoid contaminating
ground water.
The city of Emeryville, California, is
located on formerly industrial land along
the San Francisco Bay. The area is densely
developed with relatively little open space
and has contaminated soils in many areas.
The city needed to carefully consider how
best to implement green infrastructure
approaches to ensure that infiltration of
stormwater would not contaminate
ground water with pollutants picked up as
water percolates through contaminated
soils. EPA funded a grant to develop
Stormwater Guidelines for Dense, Creen Redevelopment that the Emeryville City Council
adopted in 2005 and that could help other cities facing similar challenges.94 Green

infrastructure solutions in this context included tree preservation, green roofs, permeable
pavement, and stormwater storage and use. These strategies help the city manage stormwater
while continuing to attract residents and businesses and improve the overall quality of life.95
Green infrastructure planning on a brownfield site should begin early, ideally at the time of site
assessment and cleanup so site planners can avoid techniques that might mobilize
contaminants. Information about the location and concentration of contaminants is critical for
the design, engineering, and placement of remediation measures and green infrastructure in a
new development. Often only part of a site is contaminated, and site planners can design the
layout of the development to ensure that green infrastructure practices will not mobilize
contaminants and pollute ground water. Stormwater infiltration should generally not be
considered in areas with certain types of contaminants—e.g., those that are independently
mobile, water soluble, or biodegradable. However, many green infrastructure techniques do not
require the infiltration of stormwater into the soil to function, including green roofs and
cisterns. Alternatively, on many brownfield sites, designers place an impervious barrier or cap
over contaminated soil. This cap is then covered with clean soil and vegetation that filter and
evapotranspire stormwater before it reaches an underdrain (located above the cap) that is
connected to the stormwater system.96
Incorporating brownfield sites into an overall green infrastructure plan can help ensure that
these properties return to productive use. Revitalization of the area surrounding a brownfield
site is as critical to the successful reuse of the property as its assessment, cleanup, and
redevelopment. Green infrastructure can play an important role in revitalization by helping
remedy brownfields-related environmental and public health problems while encouraging new
development and creating job opportunities for site-scale green infrastructure installation and
maintenance. These efforts can build on the work of community-based partnerships,
particularly in underserved or economically disadvantaged neighborhoods. Several approaches
can help ensure that low- and moderate-income families are not displaced following
redevelopment and that communities historically plagued with blighted properties and
environmental contamination reap the benefits of environmental cleanup and new green
infrastructure initiatives. These approaches include:

Developing a Plan
• Creating affordable housing in revitalizing neighborhoods.
• Working with minority- and women-owned businesses for environmental remediation
services and site-scale green infrastructure installation and maintenance.
• Partnering with local land trusts.
• Redeveloping brownfield sites for civic purposes such as parks.97
The city of Milwaukee
worked with partner
agencies and organizations
to develop a plan to
revitalize the 30th Street
Industrial Corridor. The
plan incorporates green
infrastructure to manage
stormwater to improve
water quality and promote
economic development.
Because the area is a
former industrial corridor
with more than 200
brownfield sites in or
adjacent to the corridor,
the city had to consider the
potential for environmental contamination when developing a plan for the area. The city
planned for the corridor as a whole, which enabled it to prioritize sites for redevelopment and
cleanup to achieve its vision of creating a new job center and economic engine in the region.98
EPA's Brownfields Program has a variety of funding sources that local governments can use for
brownfields assessment, cleanup, and associated job training programs.99 EPA also has a guide
of all federal programs that can help repurpose brownfield sites.100

Developing a Plan
F. Developing Strategies for Local Funding
To fulfill its sustainable communities and green infrastructure vision, a community needs to
have a way to pay for implementing the plan. A plan based on a community-wide vision can
generate enthusiasm from funders and/or reduce opposition to new fees or taxes.
Federal and state funding programs (as discussed in Section IV.I) can seed a local effort but are
generally not sufficient to cover all costs for plan implementation. Communities usually need to
rely on locally generated money as a long-term funding source. Most successful models for
locally funded implementation of a large-scale green infrastructure plan establish a dedicated
revenue source for capital projects, operations, and maintenance. Often this source can be a
stormwater utility. Property owners pay the utility through a fee on their water bill for the cost
of managing stormwater flowing from the property. A survey of states by the Natural Resources
Defense Council found that more than half of states have specifically delegated authority to
establish a stormwater utility to local governments, although in most states, municipalities do
have the legal authority to establish a utility if the rate structure is clearly set up to collect fees
for local services rather than taxes.101 By one estimate, between 1,800 and 2,000 stormwater
utilities exist in the United States.102
A stormwater utility fee is generally more equitable than other revenue sources because it can
be based on the actual cost the city incurs to manage stormwater from each property. How
finely the community can calibrate the fees depends on how able it is to implement a more
complicated program. Many communities use a flat fee, especially for residential properties,
that is based on the average imperviousness of a residence in the locality. A fee structured in
this way is much easier to implement than one in which each property's impervious cover is
calculated and tracked. However, a system based on actual rather than average impacts might
be more legally defensible.103 Another benefit of stormwater utility fees is that even tax-
exempt properties, such as universities and hospitals, can be required to pay their share of the
costs incurred by the municipality for stormwater management.104 Utilities can also encourage

Developing a Plan
private property owners to use green infrastructure approaches by reducing their fees.105 When
green infrastructure projects benefit just a small number of property owners, e.g., to reduce a
localized flooding problem, a local government can create a special assessment district to
charge just those property owners a fee that pays for the installation and maintenance of those
projects.
In trying to garner support for any new revenue stream, local governments can help property
owners recognize that gray infrastructure comes with maintenance costs as well—costs that can
sometimes be higher than maintenance for green infrastructure.106 In addition, costs for site-
scale green infrastructure practices will generally come down as the market for new
technologies develops. Some communities are reducing costs by developing innovative public-
private partnerships to design, build, operate, and maintain green infrastructure retrofits.107 In
a public-private partnership, the municipality contracts with a private firm that gets paid only if
it meets established performance goals. Cost savings would come from economies of scale and
standardization of practices, scheduling routes, and other maintenance procedures. Prince
George's County, Maryland, created a public-private partnership to retrofit about 8,000 acres of
existing properties with green infrastructure. The county used the potential cost savings and
the jobs the program is expected to create to install and maintain an estimated 40,000 to
50,000 green infrastructure practices as a selling point for the county's retrofit program.108
Stormwater utility fees are generally the most effective means to ensure a stable, consistent
revenue stream to implement a green infrastructure plan. To be funded through general funds
or with bonds (which must be repaid from general funds and contribute to overall debt
burdens), green infrastructure would have to compete with schools, public safety, and other
public expenditures. In addition, general funds often come from property taxes, which fluctuate,
and tax-exempt properties such as churches and schools often have large impervious surfaces,
which creates concerns about how equitably the costs are shared among property owners.109
Some communities have used financing mechanisms such as permit and inspection fees,
development impact fees, and a dedicated portion of local tax revenues. However, as with using
general funds, with these financing options, green infrastructure has to compete with other

that incorporated vegetated swales and street trees.114 Local governments can work with the
private sector to encourage these types of investment by providing education, technical
assistance, and/or partial funding through fee reductions, tax credits, or grants. Greenville
County, South Carolina, created a voluntary stormwater banking program that allows
developers to increase density in residential developments in exchange for designing projects
that better manage stormwater and protect water quality. Developer fees to participate in the
program go to a fund used for stormwater retrofits in strategic locations throughout the
county.115
G. Monitoring and Measuring Progress
A process to measure how well sustainable communities and green infrastructure approaches
help the community achieve its environmental, social, and economic goals is an important
component of an overall plan. Performance metrics can be used to communicate with
stakeholders about progress in implementing the plan, demonstrate ongoing commitment to
the community vision, encourage accountability, and suggest course corrections that can help
ensure continued progress toward goals. Involving stakeholders in choosing performance
metrics and setting up the monitoring process can help ensure that residents and property
owners, particularly those in disadvantaged communities, understand and support the goals.
Establishing target dates to achieve needed policy changes helps hold local governments
accountable and sends clear signals to the private sector about when local policies and
regulations will support their efforts. For example, the city of Chicago developed an
implementation roadmap as part of its comprehensive plan to plot out the changes it would
need to achieve each key action in the plan. The roadmap specifies target dates for a draft or
pilot and for completion. It also lists the lead agency responsible for meeting those targets.116
Recognizing the importance of monitoring how well the city's efforts are controlling combined
sewer overflows, New York City will use modeling plus three other methods to estimate flow
volume to track overflow events at the 422 outfall locations distributed across the city. In
addition to tracking stormwater flows, the city is also continuing its water quality monitoring

H. Planning for Long-Term Operations and Maintenance
All stormwater infrastructure requires maintenance, including structural repairs and
replacement and removal of trash, sediment, and debris. Both gray and green infrastructure
require establishment of clear responsibilities for maintenance, a funding mechanism, and an
inspection system. Best practices for both types of infrastructure also include having
established maintenance and inspection schedules with a system for tracking activities,
standard maintenance protocols, an operations and maintenance training program, and a
database indicating where infrastructure is located. However, some green infrastructure
systems will require different maintenance practices, resources, and expertise to maintain than
gray infrastructure, such as those required to properly identify plants and maintain plant health.
While the local government agency that traditionally maintains stormwater infrastructure might
not have this expertise, it can often be found in other parts of the government, such as the
local parks department, state land grant universities, and county extension programs or
conservation districts.120 In addition, green infrastructure is well suited for workforce
development programs to create local jobs because of a growing need for employees with skills
to install and maintain site-scale practices. Training for these positions generally does not

Developing a Plan
require a high level of formal education and can create opportunities for middle-skilled
workers.121
Operations and maintenance costs will vary based on the particular approaches used and local
conditions. Effective green infrastructure plans identify a dedicated source of funding for these
activities. Many green infrastructure funding sources like the Clean Water State Revolving Fund
programs provide loans for capital costs but cannot be used for ongoing operations and
maintenance expenses—activities that are critical to ensure the long-term performance of
green infrastructure and ultimately the success of a green infrastructure plan. Residents and
property owners who are unfamiliar with green infrastructure approaches could lose confidence
in their ability to deliver promised benefits if initial projects fall into disrepair and stop working.
When a city's green infrastructure plan involves private property, maintenance agreements are
critical to ensure the plan's long-term success by helping property owners understand their
responsibility to maintain green infrastructure practices in working order. Best practices for
maintenance agreements include specifying required activities and their frequency, inspection
and reporting requirements, and necessary easements (as appropriate). Requirements to
periodically renew maintenance agreements can help sustain engagement and remind
homeowners of their responsibilities to maintain their systems. Communities can provide a list
of contractors qualified to maintain green infrastructure practices to give property owners
additional options and create a market for maintenance services.122 The Northeast Ohio
Regional Sewer District has prepared templates for an easement allowing the construction,
operation, inspection, and maintenance of site-scale green infrastructure and a template fora
cooperative agreement for operations and maintenance.123
EPA created a document that examines the operations and maintenance practices of 22 green
infrastructure projects funded through Clean Water State Revolving Fund programs.124 It
discusses challenges to implementing an effective operations and maintenance program and
best practices learned from the experiences of the communities that implemented these
projects.

Developing a Plan
I. Identifying Federal Government Resources
The federal government has numerous funding and technical assistance programs that could
help communities implement a sustainable communities and green infrastructure plan.
For example:
• Pittsburgh used $50,000 from the U.S. Department of Housing and Urban
Development's Community Development Block Grant (CDBG) Program to fund a pilot
project called the Green Up Program. Under this program, the city identified vacant lots
that could be converted to other productive uses including community gardens, urban
agriculture, passive green space, and redevelopment. After a successful pilot, the
Pennsylvania Department of Community and Economic Development gave the Green Up
Program $500,000 to expand. The program has transformed more than 120 lots into
community assets that help manage stormwater, stabilize property values, and attract
new development.125
• In 201 2, the city of Hartford, Connecticut, received a Transportation Investment
Generating Economic Recovery (TIGER) grant from the U.S. Department of Transportation
to improve connections between its historic Main Street and the city's regional
transportation hub. Part of this grant funded the incorporation of green infrastructure
into streets as they were redesigned to facilitate walking and biking.126
• The city of Kinston, North Carolina, used funding from the Federal Emergency
Management Agency to buy property damaged by Hurricane Floyd in 1 999 to mitigate
flood risk. The city developed a plan to incorporate green infrastructure into the new
open space, which will help the city adapt to climate change and provide amenities the
entire community can enjoy.127
• The city of Aiken, South Carolina, received $3.34 million from the Clean Water State
Revolving Fund program for the design, construction, and post-construction monitoring
of green infrastructure, including bioswales, pervious pavement, and a cistern.128 The
goals of the project were to capture, store, infiltrate, and treat stormwater downtown to

incrementally as funding becomes available, and the projects' benefits begin to accrue even
before the overall plan is realized.
The federal government also has many resources that could help communities develop or

and compiles tools, case studies, and available research.131
• The smart growth website includes research, tools, and case studies to help
communities grow in ways that expand economic opportunity, protect public health and

V. Conclusion
Communities across the country are creating sustainable communities and green infrastructure
plans that can help achieve a broad range of goals, including improving water and air quality,
reducing flood risk, increasing resilience to climate change impacts, improving public health,
providing more recreation opportunities, and creating green jobs. Best practices learned from
these plans include:
• Identify an individual, organization, or entity to take the lead in organizing stakeholders
and developing a plan—a local champion committed to improving a neighborhood, city,
or region's quality of life and sustainability.
• Get local government support, making sure that public land incorporates green
infrastructure approaches and that regulations, policies, and programs are consistent
with the plan.
• Engage stakeholders early and often to develop the plan and maintain enthusiasm and
momentum during its implementation.
• Develop a vision for what the community will look like after plan implementation that
incorporates local knowledge, experience, and insight.
• Set explicit goals that the plan could achieve, spanning a range of areas from
stormwater management to economic development and climate change resilience.
• Assess assets and opportunities for green infrastructure approaches in the community
to achieve the maximum benefits for each investment.
• Look for opportunities to increase the amount of green infrastructure by using existing
public land, acquiring new public land, giving incentives to private property owners, and
ensuring that regulations are consistent with the community's goals.
• Incorporate brownfields cleanup and reuse into the plan to help ensure that these
properties are returned to productive use, and carefully plan green infrastructure
implementation to make sure that contamination is not spread.
• Explore options for establishing a dedicated revenue source for capital projects,
operations, and maintenance so that lack of funding does not slow plan implementation.
• Develop a process to measure how well the plan's implementation helps the community
achieve its environmental, social, and economic goals.
• Plan for how green infrastructure will be maintained over its lifetime at the time of
project planning so residents can see it deliver promised benefits.
• Tailor grant and/or loan applications to emphasize aspects of the plan that match a
specific program's criteria to increase the number of funding sources available for
implementation.
