Two popular trails at Discovery Park will have temporary closures starting later this month as crews upgrade underground water reservoirs for the West Point Treatment Plant.
The work is expected to start August 19, and construction will affect Loop Trail and Capehart Trail. King County says the project will take about three to five months.
The underground reservoirs store drinkable water for the treatment plant, park, and West Point Lighthouse.
In addition to the underground reservoir, King County will be installing a new 460-foot-long outfall pipe, which will help carry excess water away from populated areas in the unlikely event there’s a potable water overflow.
King County says to expect work Monday through Friday from 7am to 5pm. There will be detours, intermittent closures, and vehicles on trails. The construction materials and equipment will be staged near trails during the work.
Any trees or vegetation removed for the project will be restored with plantings recommended by Seattle Parks and Recreation.
