Stormwater improvements are being planned for Beehive Industrial Park in Tumwater to improve the water quality in Percival Creek.
To kickstart the project, the Tumwater Public Works committee endorsed to the city council a grant agreement with the Department of Ecology to hire a design and permitting consultant for the project. The grant, which is for $187,000 and requires the city to match it with $33,000, was endorsed on Thursday, Jan. 23.
Project consultant Meredith Greer explained to the committee that the 55-acre industrial area along Trosper Road is prone to flooding.
With only minimal stormwater infrastructure in the area, stormwater runoff drains to Percival Creek, which is a key priority for the city as it is a habitat for salmonids and has downstream impacts on Capitol Lake.
The industrial park was specifically chosen for the project as it is one of two areas in the Trosper Lake Subbasin, which would have a good potential to improve the health of Percival Creek.
There are also five other subbasins in the Percival Creek watershed, but Trosper Lake ranked highest in terms of priority in the city’s 2022 stormwater management plan.
Greer said they plan to install a series of linear bioretention facilities, which are blocks of soil and vegetation designed to treat and capture stormwater while enhancing curb appeal.
City staff have already identified a contractor after a competitive bidding process. The committee will review a service provider agreement with the chosen firm at a future meeting.
With the committee’s endorsement, the grant agreement will be placed on the city council’s consent agenda for its Feb. 4 meeting.
Once the grant and service provider agreements have been officially signed, design work may commence in April with an eye for completion by October.
Completing the designs within this time frame would align Tumwater with the grant schedule to apply for additional funding for construction.
Greer’s briefing did not include information as to when construction might begin.
