After the latest round of research and feedback, King County says fewer bioswales (19, instead of the original 31) are planned for Westwood and Sunrise Heights neighborhoods where “green stormwater infrastructure” is planned to reduce combined-sewer overflows at the pump station the area feeds – and fewer streets will be involved. That’s part of an announcement they’ve just sent about an open house coming up a week from Saturday:

Neighbors are invited to an open house on Saturday, Oct. 13 to learn about design updates to King County’s Barton Combined Sewer Overflow (CSO) Control project in West Seattle.

The open house is set for 10 a.m. to noon at Westside School, 7740 34th Ave. S.W., Seattle.

Combined sewer overflows occur during heavy rain when stormwater fills sewers to capacity in older parts of the city. To comply with state water quality requirements, King County will control CSOs from the Barton Pump Station through a system of bioretention swales and Green Stormwater Infrastructure in West Seattle’s Sunrise Heights and Westwood neighborhoods.

Project staff will share a number of design updates that reflect new technical information and community member feedback, including:

· A reduction in the number of bioswales and impacted streets.
· Fewer and smaller curb bulbs to preserve parking.
· Preservation of property access and tree canopy.
· Rebates and financial incentives for residents to voluntarily install raingardens and cisterns through Seattle’s RainWise program.

Additional information is available at the Barton CSO Control Program website, or by contacting Kristine Cramer at 206-263-3184 or kristine.cramer@kingcounty.gov.

Area residents are receiving a flyer – if you haven’t gotten it already – that you can see here.
