Eligible projects

Eligible 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.  Typical projects include, but are not limited to:

  • Addressing surface water overflows and flooding from creeks and lakes due to outflow blockage or undersized/failing culverts or pipes.
  • Clearance of clogged agricultural drainage systems. 
  • Improving inadequate or failing stormwater systems that are causing flooding or slope instability.
  • Addressing flooding of roads due to increased stormwater runoff.
  • Assessment of existing conditions as part of the creation of a lake management district.

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.

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.

Ineligible projects

The following types of projects will not be considered for funding:

  • Projects that are eligible for funding under Watershed Resource Inventory Area (WRIA) programs, such as salmon recovery/habitat improvement projects where flood hazard reduction is not the primary purpose.
  • Projects whose design and/or performance may transfer flooding problems upstream or downstream.
  • Projects that do not compensate for the loss of restored or undisturbed natural habitat or may adversely impact habitat or water quality.
  • Projects included on the King County Flood Control District 6-year Capital Improvement Project list.
  • Projects that provide compensatory mitigation under a regulatory requirement triggered by permitted or unpermitted impacts to a protected sensitive or critical area.
  • Activities that are not eligible for funding, but may be included in a broader project that receives other funding include site selection planning and feasibility studies.

Evaluation process, criteria and supplemental items for consideration

King County Water & Land Resources Division staff will receive and process applications on behalf of the Flood Control District. Applications will be reviewed for eligibility and applicants will be contacted to set up site visits or phone interviews with technical experts.  Technical summaries will be provided to the selection team for consideration during scoring.   The selection team will evaluate each eligible proposal using the scoring criteria – a summary of the criteria is linked on this web page. 

Following scoring, the selection team will develop a list of recommended projects for funding to submit to the Flood Control District Board of Supervisors for final decisions.  Geographic distribution of projects will be considered as an un-scored factor in developing the recommended grant award list.  Notification of award will be sent via email in late summer or early fall of 2019.
