The project complies with federal and state mandates, seismically strengthens key water infrastructure on Portland’s west side, and helps ensure a healthy, resilient, and secure water system.
The project will span from 2016 to 2024. During the first two years, major earthwork will occur along with the construction of shoring walls and the new underground reservoir. This will trigger the most significant impacts to TriMet bus service, traffic, transportation, and parking in the park.
Park users are encouraged to move safely around the park. Please watch for detours and signage and follow direction from flaggers. The public should not follow construction vehicles or buses as they may enter restricted zones. All construction-related traffic impacts are subject to change.
To avoid delays, plan ahead and visit Explore Washington Park and TriMet for transit options in the park. Please consider taking public transit and the Explore Washington Park Free Shuttle. The shuttle runs weekends only now through October 31 and will resume service in the spring.
From September 12, 2016 through March 2018, the following traffic restrictions will be in place:
OPEN FOR PEDESTRIANS/BIKES/TOUR BUSES/SHUTTLE
MULTI-USE SHARED PATH
TRIMET BUS SERVICE
PARK ENTRANCES AND EXITS
During this stage of construction:
The project entails constructing a new 12.4-million gallon, seismically reinforced below ground reservoir in the same footprint of existing Reservoir 3 (upper) with a reflecting pool/water feature on top. The new reservoir will preserve the historic drinking water function provided by the original reservoirs and be engineered to withstand ongoing landslide encroachment and potentially catastrophic effects of a major earthquake.
When complete and online, the new reservoir will supply water to Portland’s west side and serve more than 360,000 people, including all downtown businesses and residents, 20 schools, three hospital complexes, more than 60 parks, and the Oregon Zoo.
Existing Reservoir 4 (lower) will be disconnected from the public drinking water system and a lowland wildlife habitat area, bioswale, and reflecting pool will be constructed in the basin.
