Department of Ecology Water Quality Combined Funding Grant Award
ISSUE
Accept a Washington State Department of Ecology (DOE) Water Quality Combined Grant to fund water
quality improvements in the amount of $1,805,745.
BACKGROUND
In 2017, Council authorized staff to accept DOE grant funding for the design of four stormwater outfall
sites through 90% design. In 2022, Council authorized staff to accept a DOE grant funding the final
design and construction of two of the sites — Tukwila International Boulevard and Interurban Avenue.
DISCUSSION
In September 2023, Council authorized staff to submit an application to the DOE Water Quality
Combined Funding Program to fund the final design and construction for the third and fourth outfalls at
Starfire Way/Fort Dent Way and E Marginal Way. In July 2024, the City was notified that we received
the full grant award to fund the construction of two stormwater outfall retrofits.
FISCAL IMPACT
The City was awarded a $1,805,745 grant from the DOE for the construction of two stormwater outfalls.
The grant requires a 15% local city match, which is $270,861. The Project CIP, which comes from
Surface Water Fees, is sufficient to cover the match.
