Project update

February 13, 2017

Landscaping on King County site nearly complete as restoration continues in Lowman Beach Park

Landscaping on the King County site is nearly complete
King County’s contractor is nearly finished with landscaping on the County’s facility building site, including a green roof on the facility building and a rain garden north of the public staircase. Grading is also underway in Lowman Beach Park in preparation for landscaping installation.

When complete, the green roof on the facility building will absorb rainwater and improve the building’s energy efficiency. Excess water from the green roof and other parts of the facility will be directed to the rain garden, reducing runoff to nearby storm drains.

Updated hotline hours

Now that major construction is complete, the project hotline hours have changed. The project hotline will now be staffed from 9 a.m. – 5 p.m. Monday through Friday. If you call outside of these times, we will return your call on the next business day. For operational concerns or complaints, please call West Point Treatment Plant’s 24-hour phone line at 206-263-3801.

Project description

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
