The King County Flood Control District this week announced awards totaling more than $3.6 million in grants to three dozen projects across King County aimed at flood reduction.

Local grants include:

  • $200,000 to City of Normandy Park to design a replacement for two existing 18-inch culverts that convey Sequoia Creek and one 24-inch culvert that conveys Walker Creek in the vicinity of 12th Ave SW and SW Eastbrook Rd. and an existing 24-inch culvert that conveys Sequoia Creek across SW 174th Street. The culverts do not have adequate hydraulic capacity to convey high flows in the creeks and the culverts have been identified as possible fish passage barriers by WDFW.
  • $125,000 to City of SeaTac to study alternatives and design a flood reduction facility to eliminate flooding at the end of S. 180th Street. Potential solutions include a flow control structure within the ROW or acquiring property for a natural drainage system to attenuate flows.
  • King County Road Services Division to replace an existing damaged and undersized 12” pipe that runs under eleven (11) properties with a new pipe system to be located mostly within road right-of-way. The existing pipe does not sufficiently carry stormwater, resulting in frequent flooding of the roadway and private properties on 18th Ave South, along S. 107 Street and S. 106 Street.

“King County Flood Reduction Grants are tools to help local jurisdictions across the region mitigate the risks of flooding in their communities,” said Flood Control District Chair Reagan Dunn, “I’m glad to support these investments in flood reduction while restoring our aquatic habitat.”

Projects range in scope from replacing culverts to managing landslide and flooding risks in populous areas. Approved grant amounts range from $15,000 to more than $300,000.

Now in its sixth year, the Flood Reduction Grant program provides funding for municipalities, tribes, school districts and homeowner associations to deal with floodingrisks not directly caused by the major rivers of King County.

Projects awarded a grant must address certain issues in order to be eligible. Examples of eligible projects include addressing flooding from creeks or lakes due to outflow blockage or failing culverts or pipes, addressing flooding roads caused by increased stormwater runoff, clearing or maintaining agricultural drainage systems and more.
