Chesapeake Assessment Scenario Tool (CAST) was first developed in 2011 by Olivia H. Devereux and Jessica R. Rigelman with funding provided by the U.S. Environmental Protection Agency (EPA). The immediate need was to provide local jurisdictions, such as counties, with a tool to provide input into the TMDL WIP process.

With continued funding from the U.S. EPA, the functionality of CAST has been expanded to serve multiple needs for environmental planning in the Chesapeake Bay Watershed.

Future enhancements are developed with input from the states and local jurisdictions, the Chesapeake Bay Program, and the EPA. The tool will continue to evolve to meet the needs of users.
