Barton CSO Control Project
Green stormwater infrastructure
September 15, 2014 Project Update --
Seattle Public Utilities to test water flow in roadside rain gardens during week of September 22. View City of Seattle notification (September 15, 2014).
Construction of the roadside rain gardens for the Barton CSO Control project is underway across the neighborhood. As a result of the significant progress made by Goodfellow Bros., Inc., this spring, the contractor has begun work on two blocks originally planned for 2015, 34th Avenue SW between SW Cloverdale Street and SW Thistle Street, and 34th Avenue SW between SW Trenton Street and SW Cloverdale Street. The five blocks scheduled for 2015 construction all had deep wells installed at the southern end of the blocks earlier this spring. View Construction Update (PDF), June 2014.
To keep the neighborhood up to date on street by street activity and construction impacts, the project website will be updated weekly. The goal will be to update the website every Monday afternoon, but there may be some Tuesday updates depending on what’s happening with the construction crews.
If you are on an impacted street, you will still receive fliers providing advance notice of major activities (posted on the construction page). And of course if you have any questions or concerns, do not hesitate to call the 24-hour construction hotline: 206-205-9184, or email Kristine.email@example.com.

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).
