Affordable housing cleanup grants

Ecology has developed the Affordable Housing Cleanup Grant Program (AHCGP) to help advance environmental cleanups for affordable housing developments. This program includes both cleanup and planning grants. Affordable Housing Cleanup Grants can cover remedial action costs, including planning, investigative, and technical work needed to clean up contaminated sites. The purpose of the AHCGP is to expedite the cleanup and redevelopment of contaminated sites into affordable housing use and lessen the impact of cleanup costs.

Learn more: Ecology presented information about the Affordable Housing Cleanup Grant program at the Fall 2021 Housing Washington conference. The recording is 50 minutes long, and includes questions and answers at the end.
