EnviroAtlas Communities

EnviroAtlas provides wall-to-wall data for the entire United States. More fine-scale data are provided for hundreds of U.S. communities. EnviroAtlas currently includes fine-scale data for more than 1400 cities and towns centered on 30 U.S. urbanized community areas (shown in the map above). Selection of these communities is based on: 

  • geography,
  • ongoing local research,
  • data availability,
  • and opportunities to leverage other EPA projects.

In general, EnviroAtlas defines the community boundaries by the census block groups falling within the census urbanized area for the main community in the area. This means that EnviroAtlas communities often contain all or part of multiple municipalities.
