Learn about work completed in 2014 and winter maintenance activities, and see images of the new roadside rain gardens in the fall 2014 Barton CSO newsletter.
If you have any questions or concerns, do not hesitate to call the 24-hour construction hotline or email Kristine.firstname.lastname@example.org.
24-hour construction hotline: 206-205-9184
The construction hotline will stay active this winter. Please use it if you see problems with the roadside rain gardens such as standing water longer than 24 hours after a storm, vandalism, or excessive weeds. Once construction is complete in 2015, there will be a long-term maintenance hotline for neighbors and community members to report problems.
Barton basin and project location.
Barton CSO Control Project area
King County will construct bioretention swales (roadside rain gardens), a type of green stormwater infrastructure, in the City of Seattle’s planting strips in the Sunrise Heights and Westwood neighborhoods. Street runoff will be diverted away from storm drains and into the vegetated swales. Once in the swales, the water will filter through soil to an underdrain, which will take the water to a deep well for slow infiltration underground.

In 2008, King County reported that the Barton Pump Station averages 4 overflows per year that discharge approximately 4 million gallons of raw sewage and untreated stormwater into Puget Sound near the Fauntleroy ferry dock. King County is working to meet current regulations set by the Washington Department of Ecology that require no more than one untreated discharge per year on a long term average. Taking stormwater out of the conveyance system in Sunrise Heights and Westwood will reduce these combined sewer overflows (CSOs).
