Construction & Closures

Washington Park Reservoir Improvement Project

February 12 update: The Washington Park Reservoir public space is anticipated to partially open in summer 2026, beginning with the upper promenade area around the reflecting pool. This upper area will include walking paths, the grand staircase, an ADA-accessible route, the interpretive wall, and the gatehouse plaza. The lower area (including the lowland habitat and bioswale) will remain closed initially due to safety improvements and will open at a later date. The reflecting pool and cascading water feature may be intermittently off as crews continue testing and resolving technical issues. Periodic closures and construction-related impacts may continue in the surrounding area, including road work along SW Sacajawea Boulevard.
