Finding Potential Sites for Redevelopment

The app’s map contains a selection of Brownfield sites over 100 acres in size and all National Priorities List and Superfund Alternative Approach Superfund sites. These sites can be searched and filtered using several parameters, including redevelopment context (e.g., proximity to transportation, energy infrastructure, population and water availability), location, size, site status and site name. 

Filtering 

  • Select one of the Filter tools in the top right corner of the screen. The filter on the left is for Superfund sites and the filter on the right is for Brownfield sites.
