Project Updates


September 8, 2016: Breaking Ground, Temporary Impacts to Travel & Parking

Downloadable file: Traffic Advisory 
Downloadable file: Brochure

The Portland Water Bureau and contractor Hoffman Construction Company have begun an eight-year capital improvement project to update the Washington Park reservoir site.

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:

ROAD CLOSURES

  • SW Sacajawea Blvd. will be completely closed to all vehicle and bike traffic and pedestrian use from the intersection of SW Sacajawea Blvd./SW Rose Park Rd./SW Wright Rd. to SW Park Pl.
  • SW Sherwood Blvd. will be closed to all vehicles from SW Kingston Ave. to the Soccer Field.
  • SW Sherwood Blvd. will be closed to all vehicles, bikes, and pedestrians from the Soccer Field to SW Sacajawea Blvd.

OPEN FOR PEDESTRIANS/BIKES/TOUR BUSES/SHUTTLE

  • The sidewalk of SW Sherwood Blvd. will remain open for pedestrian use and bike traffic from SW Kingston Ave. to the Soccer Field.

TRAFFIC REVERSAL

  • Traffic flow will be reversed on SW Lewis Clark Way. One-way traffic will travel SW Lewis Clark Way and exit the park on SW Park Place.

MULTI-USE SHARED PATH

  • Starting Sept. 16, 2016, a designated paved-path separate from vehicles will be available on SW Lewis Clark Way. Pedestrians and cyclists can use the path to travel both in and out of the park on SW Lewis Clark Way. Cyclists are required to walk and not ride bicycles on the path.
  • Prior to Sept. 16, pedestrians are encouraged to use the stairs by the Lewis and Clark Memorial Column or be escorted around SW Lewis Clark Way.

TRAILS

  • Pedestrians and cyclists can enter and exit the Madison Court Trail on SW Madison St. and SW Sacajawea Blvd. The trail will close intermittently; watch for signage.
  • The Mac Trail will remain open. Pedestrians are cautioned to watch for trucks where the trail intersects with SW Sherwood Blvd. and SW Sacajawea Blvd.

NO PARKING

  • All parking spaces closed on SW Sacajawea Blvd., SW Sherwood Blvd., and SW Lewis Clark Way.

TRIMET BUS SERVICE

  • Line 63 - Washington Park/Arlington Heights will be detoured and stops 6177, 4346 and 4343 will be closed. Check TriMet.org for updates.

PARK ENTRANCES AND EXITS During this stage of construction:

  • Three park entrances will be available: W Burnside Rd. to SW Tichner Dr.; SW Fairview Blvd. to SW Knights Blvd.; and SW Canyon Rd. to SW Knights Blvd.
  • Four park exits will be available: SW Tichner Dr. to W Burnside Rd.; SW Fairview Blvd. to SW Knights Blvd.; SW Lewis Clark Way to SW Park Pl.; and SW Knights Blvd. to SW Canyon Rd.

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.

June 29, 2016: Washington Park Reservoir Improvements Project Monthly Update

In order to comply with federal and state mandates and ensure a healthy, resilient, and secure water system, the Portland Water Bureau and Oregon general contractor Hoffman Construction Company are moving forward with an eight-year capital improvement project to update the Washington Park reservoir site at 2403 SW Jefferson Street. 

SUMMARY
The project includes building a new, seismically reinforced below ground reservoir.

The new reservoir will preserve the historic drinking water function provided by the original reservoirs at the site and be engineered to withstand ongoing landslide encroachment and potentially catastrophic effects of a major earthquake. A reflecting pool/water feature will be constructed on top in the same general footprint as the historical Reservoir 3. Reservoir 4 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.

When complete and online, the new underground reservoir will supply water to Portland’s west side and serve more than 360,000 people, including all downtown businesses and residents, 20 Portland public schools, three hospital complexes, more than 60 parks, and the Oregon Zoo.

SCHEDULE

  • Proposed Schedule
  • July 1, 2016: Begin construction
  • December 31, 2019: Complete construction on new Reservoir 3
  • December 31, 2020: Disconnect Reservoir 4 from the public water system
  • 2023-2024: Complete project completed

UPCOMING PROJECT WORK & IMPACTS
The project will span eight years. The first two years (2016-2018) will trigger the most significant impacts to traffic, transportation, and parking in the park. Washington Park users are encouraged to travel to and move safely around the park and its attractions by using the bus and light rail, walking, biking and skating, and taking the free park shuttle. Visit trimet.org and explorewashingtonpark.org for transit options.

IMap showing traffic delay locationsmpacts: May – September 2016

  • Traffic Delays: Travelers may experience intermittent traffic flow delays up to 20 minutes on SW Sacajawea and SW Sherwood Boulevards due to pre-construction maintenance and removal of vegetation and trees in the project site.

  • Parking: All parking will remain open on SW Lewis Clark Way and SW Sacajawea and SW Sherwood Boulevards.

  • Park Facilities: All park facilities will remain open.

  • TriMet Bus Service: TriMet Bus Line 63 may have minor delays. Stop ID 6177 at SW Sacajawea/ Sherwood may be intermittently affected depending on pre-construction activity. Check trimet.org for real time updates.

FUNDING & BUDGET
The project is part of the Water Bureau’s Capital Improvement Program. It is funded by revenue bond proceeds backed by the utility ratepayers’ fund. Currently, 100 percent of the project’s design is complete. With high confidence, the Water Bureau now appraises the total project budget for the life of the project at $190 million (+/- 10 percent). 

MEDIA & COMMUNITY EVENTS HONORING THE RESERVOIRS
In June 2016, the Water Bureau held events for local media outlets and members of the community to honor the past, present, and future of the Washington Park reservoirs. Five media outlets and close to 100 community members attended the events, taking the opportunity to photograph the reservoirs and participate in guided walking tours and a “toss a penny into the reservoir, make a wish” tribute. View KOIN Channel 6’s coverage and additional photos of the events on the Water Blog.
