Flood control assistance account program (FCAAP)

The Washington Legislature established the Flood Control Assistance Account Program (FCAAP) to assist local jurisdictions with comprehensive floodplain management planning and implementing actions to control flooding. Funding is determined every biennium by the state Legislature. Eligible projects include:

  • Comprehensive flood hazard management plans
  • Feasibility studies
  • Match for federal projects
  • Flood control maintenance projects
  • Emergency projects

Funding cycle

  • Amount of funding available: Approximately $1.5 million for planning projects and $150,000 for emergency flood response projects.
  • Funding allocated:
  • Grant award limit: There is no grant award limit. However, to fund multiple flood planning projects, we anticipate a maximum of $250,000 per grant.
  • Amount of matching funds required: 25 percent for planning projects and 20 percent for emergency flood response projects.

Applications are not being accepted at this time.

Planning project applications now being accepted.

The planning project application period has closed for the 2021-2023 Biennium.

Emergency project applications are accepted through June 30, 2023.

Applicants who want to apply for an emergency flood response grant must first get approval from Ecology. Please contact Scott McKinney, FCAAP Fund Coordinator, with emergency project proposals, and we will initiate a new grant application in Ecology's Administration of Grants and Loans (EAGL) online system.
