The RFP for the EPA Wetland Program Development Grants has been posted to grants.gov.  The primary focus of these grants is to develop/refine state and tribal wetland programs.  A secondary focus is to develop/refine local (e.g. county or municipal) programs.  All monitoring and mapping projects should transfer information or advance the state of knowledge and therefore are eligible under this grant.  More information can be found here.

The Wetland Grants Database is also available to view previous projects.

Good luck!
