Pool closures
The Weyerhaeuser King County Aquatic Center (WKCAC) is more than 30 years old and has many systems that need replacement and upgrades. Improvements will be made from August 1 to mid-September 2022, (Phase I) and Summer 2023 (Phase II) that will result in temporary pool closures.
- Phase I (August 1 through mid-September 2022): Facility closure to resurface pool deck with non-slip surfaces, replace elevator equipment that has reached the end of its useful life and to improve ADA accessibility.
- Phase II (Summer 2023): Closure for HVAC and Water Heating Systems, Lighting System replacement.
These projects lower maintenance costs, improve ADA accessibility, replace materials and systems that are at the end of their useful life with energy-efficient systems, and make it possible for the WKCAC to continue to attract the same quality of high-level competitions that the facility has hosted since it was built in 1990.
Funding for this project is made possible thanks to the 2020-2025 King County Parks, Recreation, Trails, and Open Space Levy. Thank you for your support!
