Murray CSO control
Building a new storage tank to protect Puget Sound
March 29, 2017
Contractor expected to finish work in April, King County will raise safety railing in May to protect public safety
Restoration of the Murray CSO Control Project site is nearly complete. King County’s contractor will finish the remaining project work by the end of April, including:
- On-site landscaping: The contractor will plant new grass at the base of the public staircase. This work is weather dependent.
- Restoration of Lowman Beach Park: New irrigation is being installed and grass will be planted. The temporary fencing around the park will remain up through spring until the grass is established.
- Project art: The project artist, Robert Horner, will be sealing the rammed earth walls and installing art inlays and rock gardens along the public staircase.
The contractor will remove construction fencing and open the public staircase after this work is complete. Railings were recently installed around the rain garden and on the facility roof near public viewpoints. To protect public safety, the County will be raising the height of these railings. This work will occur during the month of May. Temporary barriers will be in place on the facility roof until the new railings can be installed.
Fence art available for reuse
The plywood art boards that decorated the construction fence for nearly three years are available to the community for reuse. If you or your community group are interested in giving one or more art boards a new life, please contact Kelly Foley at email@example.com or 206-477-8621 by no later than Friday, April 14.

King County built a million-gallon underground storage tank across the street from Seattle’s Lowman Beach Park to reduce combined sewer overflows (CSOs). The tank stores excess stormwater and wastewater that would otherwise overflow into Puget Sound when the Murray Pump Station exceeds maximum capacity. Learn more about this project.
The Murray Wet Weather Facility began operating in November 2016. All project activities are expected to be complete in early 2017. Below is a list of remaining project activities that are underway or planned for early 2017:
- Site landscaping
- Lowman Beach Park restoration and landscaping
- Project art
