Brief Description:
Background
EnviroAtlas is ORD's online spatial decision support tool for viewing and analyzing the supply,
demand, and drivers of change related to natural and built infrastructure at multiple scales for
the nation. Maps and text identify known relationships between the goods and services
provided by nature and societal benefits, in order to facilitate a full accounting of how decisions
affect progress towards sustainability. In addition to watershed-scale data covering the
coterminous U.S., EnviroAtlas includes high-resolution landcoverand metrics for selected
communities; these metrics are summarized by Census block group. The community
component of EnviroAtlas emphasizes local natural and built infrastructure with direct
relevance to public health, together with fine-scale distribution of the population and
disproportionately vulnerable groups.
Approach Taken
More than 100 metrics are developed consistently across featured communities; examples
include number of residents within 300m of major roadways, percent of residents greater than
500m walking distance from a park entrance, and number of schools and day-care centers with
less than 25% surrounding green space. In addition to block-group summaries, numerous
metrics are provided at 1-meter resolution, such as tree cover along streams and roads, and hot
spots of impervious surface and green space. EnviroAtlas communities are selected along
geographic and other gradients to facilitate research and transferability of information. Varying
widely in size and population, they are delineated based on the Census definition of urban
areas and extend well beyond municipal boundaries.
Results
Twelve communities have been completed and posted in EnviroAtlas to date, meeting a key
FY15 deliverable for SHC Project 1.62 of additional communities. These communities with
boundaries based on the US Census Urban Areas encompass the following central cities and
towns:
New Bedford, MA	Durham, NC	Woodbine, IA
Portland, ME	Tampa, FL	Fresno, CA
Paterson, NJ	Milwaukee, Wl	Phoenix, AZ
Pittsburgh, PA	Green Bay, Wl	Portland, OR

-------
The EnviroAtlas, including the community component, was peer-reviewed in 2014, no further
peer review was required for this deliverable.
Significance
Communities, EPA Program and Regional Offices, and other vested entities typically lack
sufficient local environmental information to assess the full ramifications of many individual
and cumulative decisions. Myriad activities of multiple organizations directly and indirectly
affect public health, community resilience, social equity, and other key components of
sustainability. Decision-support tools and information are needed to facilitate a more full
accounting of the costs, benefits, and trade-offs involved in alternative actions. Fine-scale
spatial data on urban built and natural features are a key component of this decision support,
enabling more deliberate and integrated management of community assets.
Expected Use by Partners or Others
EnviroAtlas community data and information are already in use by local governments and
academia. While unexpected uses continue to be revealed, the high-resolution maps and
information are anticipated to be used in ways that include:
¦	Informing Health Impact Assessments (HIAs)
¦	Identifying locations for converting stormwater infrastructure from "gray" to "green"
¦	Prioritizing urban tree planting sites to optimize multiple public benefits
¦	Increasing equitable distribution of urban parks and greenways
¦	Empowering citizens to evaluate their existing and potential community green assets
¦	Educating the next generation of decision-makers
¦	Supporting the Rockefeller 100 Resilient Cities project and EPA's Making a Visible
Difference in Communities initiative
