June 9, 2015 Update -- Major construction of roadside rain gardens complete
King County’s contractor, Goodfellow Brothers Inc. (GBI), has completed major construction of roadside rain gardens on the five blocks shown in orange on the map below. Over the next few weeks, crews will finish up some minor landscaping work.
For the next two months, the recently constructed roadside rain gardens will be protected with green fencing while plants begin to grow. All streets and sidewalks will be open during this time.

Later this summer after plant establishment is complete, crews will run one-day tests in the street to make sure water flows into and drains out of each rain garden as intended. There will be some parking restrictions near the work area during flow testing.
Watch for a summer newsletter with information on the future of the roadside rain gardens, and watch for an invitation to a fall celebration of the project’s completion.

Monitoring and maintenance are still ongoing on the ten blocks completed in 2014. To learn more, view the facility operations page.

Barton basin and project location.
Barton CSO Control Project area
King County is constructing roadside rain gardens, a type of green stormwater infrastructure, in the Sunrise Heights and Westwood neighborhoods in West Seattle. Located in the planter strip between the curb and sidewalk, these roadside rain gardens will divert stormwater runoff away from the combined sewer system. When it rains, stormwater will filter through the rain garden soil to a drain pipe, which will take the water to a deep well for slow infiltration underground. Keeping stormwater out of the sewer system will reduce CSOs of raw sewage and untreated stormwater into Puget Sound near the Fauntleroy ferry dock. For a summary of improvements, along with information on plant palettes and trees, click here.
In 2008, King County reported that the Barton Pump Station averages four 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.
What you can expect during construction
- Work hours Monday through Friday, 7 a.m. to 6 p.m. Advance notice will be provided for any work outside those hours.
- Construction materials and equipment on the street and material storage in the right-of-way planter strips.
- Noise and activity typical of a construction area.
- The contractor will maintain local and emergency access at all times although there will be times when local access will need to be coordinated with the construction crew.
- Uninterrupted delivery of mail and packages and uninterrupted waste management pick up.
- All work to occur in the public right-of-way.
Being a good neighbor
King County is committed to being a good neighbor and will work directly with the community throughout construction to reduce impacts whenever possible. If you have questions or concerns, please call the 24-hour construction hotline at 206-205-9184 or email Kristine.firstname.lastname@example.org.
