GROSS Grants

Grants of Regional or Statewide Significance (GROSS) are competitive grants that assist permittees in completing projects that will benefit multiple permittees. The Studies, Reports, and products are hosted on this page.  

The grants are organized by which side of the state (Eastern or Western) the jurisdiction awarded is on and are cataloged dating back to 2010. They will appear in descending order starting with the oldest grant products. This page will be updated regularly as new grants are awarded and products are created. For more information on the GROSS grant application process, who’s eligible, and supported project types please visit the Department of Ecology GROSS Grant page.
