Status of EnviroAtlas
EnviroAtlas has been publicly available since May 2014 (News Release, May 7, 2014). Development plans for EnviroAtlas extend through 2019, with regular updates taking place as they become available.

Latest Updates to EnviroAtlas
New Map Features
- Universal Search: All EnviroAtlas data layers, including people and built spaces and boundaries, are now housed under a single tab. Users can now easily search all 400+ data layers.
- Featured Collections Widget: Featured Collections are clusters of data that highlight different environmental decision-making contexts. The new EnviroAtlas widget contains four Featured Collections:
- Demographics Widget: The Demographic widget contains data sourced from the 2011-2015 American Community Survey (ACS) & US 2000 & 2010 Census data. The widget contains:
- hundreds of demographic variables
- user-preferred symbology (chloropleth OR markers)
- scale-dependent data displays (e.g., county, census tract, and census block group) that recalculate when the map is zoomed in or out
- Urban Heat Islands and Vulnerable Populations
- Estimated Floodplains data were developed to close critical gaps where FEMA Digital Flood Insurance Rate Maps are unavailable. FEMA floodplain data were used to train a machine-learning algorithm to predict floodplain presence or absence for the entire continental United States, establishing full National coverage.
- FEMA based flood hazard data were recently released, allowing for census-block scale identification of land area, impervious surface, and population in flood risk zones in the 24 EnviroAtlas community areas
- Modeled Species Richness: Previously available for Southeast and Southwest regions only, these EnviroAtlas Species Richness data are derived from habitat suitability models and now extend across the country for wall-to-wall National coverage. All of the layers related to species richness give users the option to select from maximum richness, mean richness, or Normalized Index of Biodiversity (NIB).
- Roads near streams: Identifies paved roadways within 50 m of a stream for enhanced runoff mitigation planning.
- Percent tree canopy: Percent of land area that is covered by tree canopy within each subwatershed (12 digit HUC) and Percent tree canopy in stream buffers.
- New communities, including Philadelphia, PA; Sonoma County, CA; and Salt Lake City, UT (2019). Current plans include more community additions.
- Featured collections of data in the interactive map and use cases that provide descriptive examples of how to use EnviroAtlas data (Ongoing).
As the project progresses, this webpage will be updated with the latest news on EnviroAtlas.
