Park Alert: Water shut off evenings of April 6 and April 24, 2023

The main water valve is being replaced at Marymoor Park for two nights from 9 p.m. – 8 a.m., April 6 and April 24, 2023. Active construction will be taking place at Marymoor’s west entrance, located at the intersection of West Lake Sammamish Parkway NE and NE Marymoor Way.

During construction hours, all water will be shut off across the entire park. Restrooms, handwashing, dog washing, water fountains, and other water sources will not be accessible. Evening work is taking place to minimize impact on park users and staff. Please use Sani-cans for restrooms and hand sanitizer stations during construction hours.

Water use and restrooms will be back to usual 24/7 access starting at 8 a.m. on April 7 and 8 a.m. on April 25.

NE Marymoor Way will remain open during construction with flaggers present. Please follow all construction signs and directions from the flaggers. Wait times of up to 15 minutes may occur, so please plan ahead if you are driving in the area.

Thank you for your patience as we complete this important work!
