Department of Ecology Water Quality Combined Funding Grant Opportunity
ISSUE
Authorize the submittal of a grant application to the Washington State Department of Ecology (DOE)
Water Quality Combined Grant Program to fund water quality improvement projects.
BACKGROUND
The DOE is currently seeking applications for its Water Quality Combined Funding Opportunity. Current
City policy requires approval by the appropriate Committee before applying for grants.
DISCUSSION
The grant application will request $1,643.365.00 to fund the final design and construction of water
quality treatment solutions for two stormwater outfall sites. TIC has previously authorized staff to accept
DOE grant funding for the design of four stormwater outfall sites through 90%. TIC also authorized staff
to accept a DOE grant funding the final design and construction of two of the sites — Tukwila
International boulevard and along Interurban Avenue.
This application seeks DOE funding for the final design and construction of the third and fourth catch
basins near outfalls at Starfire Way/Fort Dent Way and E Marginal Way.
FISCAL IMPACT
A 15% match is required for this funding opportunity, which if funded, would be $246,504.75.
Matching funds will be drawn from the Storm Water Quality Retrofit Program CIP.
RECOMMENDATION
The Committee is being asked for approval to submit an application to DOE for its Water Quality
Combined Funding Grant Opportunity for Fiscal Year 2025.
