As of 2/7/2022 - Design will continue through 2022. Construction of the new pump station is anticipated to begin in 2023 and take up to a year and a half to complete. Environmental Services is designing a project to remodel the 46-year-old Force Avenue Pump Station in North Portland. Increased pumping capacity will accommodate growth and future demands on the sewer system. Improved reliability, access, and safety will protect public health and the environment. The Force Avenue Pump Station was built in 1974. It pumps sewage and stormwater from North Portland to the Columbia Boulevard Wastewater Treatment Plant. Its service area includes Hayden Island, Tomahawk Island, and 2,130 acres of primarily industrial and commercial zoned areas, with some multifamily residential areas. Design Update
Environmental Services has completed its evaluation for three options for the pump station layout. Two were expansions on the existing Force Avenue site, and one was a relocation to the Portland Expo Center property across the street. Environmental Services has determined that moving the pump station to the Expo Center property is the best option to provide the most cost-effective and suitable location to accommodate the pump station upgrade. The Expo Center and its governing body, the Metropolitan Exposition and Recreation Commission (MERC), continue to engage with the City of Portland on this proposal.
In addition to several pump station improvements, the Force Avenue Pump Station Upgrade Project will require the replacement of two air release valves (ARV) at the following locations: On a levee along the Columbia Slough Trail near the Heron Lakes Golf Course
Before the entrance sign to the Heron Lakes Golf Course at Force Avenue
The first ARV is located along the Columbia Slough Trail at a point east of Moore Island and across from an access road off N Cottonwood Street. This work is tentatively scheduled for March of 2021: Construction will require closing the Columbia Slough Trail to pedestrians and bicyclists for approximately one day.
The closure will likely be from N Denver Avenue to the Columbia Slough bridge by the Columbia Boulevard Wastewater Treatment Plant.
The second ARV location is just before the entrance sign to the Heron Lakes Golf Course at Force Avenue. This work is anticipated to begin in the spring of 2022: The ARV construction will not interfere with Heron Lakes Golf Course operations or events, because the vault will be located in the rough.
A fence around the work site will protect the public.
There may be traffic delays when construction is within the narrow part of the Force Avenue roadway.
Environmental Services is coordinating with the Army Corps of Engineers, the Multnomah County Drainage District, and the Parks Bureau to obtain any necessary permits to access the sites and replace the air release valves. As of September 16, 2020 The project is moving toward the 90 percent design phase. The Engineer of Record and PM information will be made available at the time of the public bid. The owner anticipates that it will out for a public bid at some point during the spring of 2022. Construction is will begin shortly thereafter and to be completed in the summer of 2023.
