Traffic Advisory 04/22/16: Preparation for Washington Park Reservoir Improvements Project Begins Spring 2016, Impacts to Travel - 04/22/16
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.

Beginning late April 2016 and lasting for two to three weeks, the Portland Water Bureau and our contractor will begin preparing the project site by working with the City of Portland's arborist to remove vegetation and trees below lower Reservoir 4 near the pump station facilities and adjacent to SW Jefferson Street. All work will occur within the project site.

Selective tree pruning and inspection will also occur within the project site, around Reservoir 3 and 4, and along SW Sacajawea Boulevard, SW Lewis Clark Way, and SW Madison Court. Pruning and inspection will occur intermittently Monday through Friday, between 7 a.m. to 4 p.m.

Travelers and park users are asked to exercise caution and drive slowly around tree pruning work areas.

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 http://TriMet.org and www.ExploreWashingtonPark.org for transit options.

The project entails building a new, seismically reinforced below ground reservoir. The reservoir will not only maintain the historic drinking water function provided by the original reservoirs, but will be engineered to withstand ongoing landslide encroachment and potentially catastrophic effects of a major earthquake and will feature a reflecting pool 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 habitat area/bioswale and a reflecting pool will be constructed in the basin.
