New Haven, CT and surrounding area

Towns and cities rely on clean air, clean water, green space,
and other natural amenities for economic sustainability and
quality of life, yet their benefits are not always fully
understood or considered in local decisions. EPA and its
partners are producing EnviroAtlas to help communities
better use environmental assets for public good.

EnviroAtlas includes an online interactive mapping
application that anyone can use. The interactive map
contains over 300 maps available for the U.S., as well as
100+ fine-scale maps for selected U.S. communities about
existing and potential benefits from the local natural
environment. The EnviroAtlas community component is
based on 1-meter resolution land cover data. Information
derived from these data is summarized by census block
groups; more spatially explicit map layers are also provided.
This fact sheet highlights some of the many community data
layers available for the featured area of New Haven,
Connecticut.

Background

The EnviroAtlas boundary for the New Haven area was
determined using the 2010 Census definition of an Urban
Area. In addition to New Haven, it includes Meriden, Old
Saybrook, and Orange, as well as other towns within New
Haven and Middlesex Counties. The area measures 1,161
square kilometers, and encompasses 444 census block
groups.

The New Haven area is in the Long Island Sound Coastal
Lowland ecoregion. It has a mild climate with very warm
and humid summers and moderately cold winters.

The area was historically vegetated with coastal hardwood
forests; however, much of the natural vegetation has been
removed for urbanization. The leading industry sectors in
the area are education and health care. Yale University and
Yale - New Haven Hospital are city's largest employers.
The demographics of the New Haven community area
indicate that the potential exists for income and other
disparities in the distribution of environmental assets.
EnviroAtlas includes demographic maps that can help
screen for potential health and well-being disparities
resulting from disproportionate distribution of urban

Ecosystem Services Overview
In EnviroAtlas, the benefits humans receive from nature are
grouped into seven categories that demonstrate the
interconnectedness of these ecosystem services:

•	Clean air

•	Clean and plentiful water

•	Natural hazard mitigation

•	Climate stabilization

•	Recreation, culture, and aesthetics

•	Biodiversity conservation

•	Food, fuel, and materials (data available only for
communities with farm land)

Examples of some of the data included in EnviroAtlas are
detailed below.

Green Space and Trees

Research indicates that physical and visual access to trees
and other green space has positive physiological, cognitive,
and emotional benefits. Lack of these resources in the places
where we live, learn, work, and play can adversely impact
human health and well-being. In the New Haven community
area:

•	There are 1,419 square meters of green space per
person.

•	About 1,600 residents have less than 5 percent tree
coverage within 50 meters of their home.

•	There are 5,307,743 tons of carbon stored in the
local tree biomass, with an additional 53,980 tons
sequestered annually. Carbon in the atmosphere is
an important factor related to climate stabilization.

•	2,792,668 kilograms of the common air pollutant
ozone are removed from the air by local trees every
year.

Access to Parks

Parks provide access to green space, encourage physical
activity, and improve the livability and aesthetics of urban
areas. Those who live closer to parks may be more likely
to receive the multiple benefits associated with this
proximity. Easily accessible parks are generally considered
to be within 500 meters" walking distance, which takes
less than 15 minutes for an average healthy person.

•	An estimated 33 percent of the New Haven population
has a park entrance within 500 meters' walking distance
(dark and medium green areas in figure above).

•	An estimated 40 percent of the New Haven area does
not have a park entrance within 2 kilometers" walking
distance (orange to red and grey areas in figure above).
