Gladstone Pipeline and River Intake Construction Update
This update includes construction work in the following areas. Scroll down for specific information on each location:
- River Intake Pump Station (RIPS) on the Clackamas River
- Gladstone pipeline work progressing north on Bellevue Avenue
- Horizontal directional drilling under the Willamette River in Meldrum Bar Park
River Intake Pump Station (RIPS)
This week, divers removed remaining sand bags as well as some piling from the river. All of this work will be complete by September 15, the end of the in-water work period.
Mechanical and electrical work is continuing within the new structure. Throughout this month, crews will continue placing architectural metal panels on the outside of the structure.
In early October, the large red crane will be removed from the site and replaced with a smaller crane.
Gladstone pipeline work progressing north on Bellevue Avenue
This week, crews laying pipe along Bellevue Avenue completed work in the intersection at W. Arlington Street. Next week, pipe installation will continue to progress north along Bellevue Avenue. Crews are expected to begin crossing Berkeley Street around Monday, September 8th.
Please watch for signage directing you safely around all pipeline work. Also, there are large pieces of equipment on the roadway, so please avoid the one block work areas during construction.
Some key information about construction:
- Traffic detours and temporary closures will be in place during work hours, usually one block at a time.
- Equipment (excavators/loaders) and material (gravel/rock/large pipe) will be stored and parked in the right-of-way along W. Clackamas and Bellevue, typically along the gravel shoulders or parking areas. This will move as construction progresses, but will be stored overnight and on weekends.
- During work hours, there will be no on-street parking in the one block closure zone where construction is occurring.
- For safety, residents located in the closed work zone who usually park along the street during the day, will need to park elsewhere on side streets.
- Neighbors may notice an increase in truck traffic and noise during construction.
Work hours are 7 a.m. to 6 p.m., Monday through Saturday. There is no work planned for Saturday, September 6th.
HDD pipeline under the Willamette River in Meldrum Bar Park
Work is progressing well on upsizing the hole. More passes will be made with larger drill bits (or reamers) until the hole is large enough for the water pipe to be pulled through. “Pullback” of the pipe could occur as early as late September, and could take between two to five days. A drill rig will pull the pipe through the hole under the river, from Meldrum Bar Park to Mary S. Young Park. During this phase, operations must occur round-the-clock, in a continuous fashion, to ensure the hole remains open.
We apologize for the inconvenience this work may cause and thank you for your patience as construction progresses.
