Grant Description
Grants to Washington nonprofit organizations, government agencies, tribes, schools, special purpose districts, and homeowner associations for activities that reduce the risk of flooding in eligible locations. Funding is available for four project categories: coastal flooding and erosion; urban streams; original flood reduction; and fish passage and culvert replacement. Eligible proposals are for medium and small local flood reduction projects in King County.

All projects will meet the following requirements:

  1. The proposed project must provide a flood reduction benefit so that it directly addresses existing or potential flooding.
  2. The proposed project must provide a clear economic benefit that extends beyond the applicant to the broader public good, such as but not limited to:
    • Maintaining public access to residences, businesses or infrastructure.
    • Maintaining safe roads for conveying people, goods, and emergency services.
    • Maintaining existing agricultural or recreational uses.
    • Addressing existing or potential threats from flooding to public safety, water quality or infrastructure.
    • Maintaining populations of anadromous fish.
  3. The proposed project must include on-the-ground structural improvements with the following exceptions:
    • Proposals may be phased so they include site assessment, design, and/or permitting only, as long as the application demonstrates that these early phases will ultimately lead to construction of on-the-ground structural improvements in a future phase (i.e., construction phase not funded under this current round).
    • The project involves the assessment of existing conditions related to the creation of lake management districts.
