River Intake Pump Station (RIPS) - new pumps begin pumping water to the treatment plant!

A major milestone was reached this week with the new pumps now pumping water to the existing treatment plant in West Linn! A three-month commissioning period is now underway for the new pumps.

Crews are almost finished placing the architectural stone veneer as part of the entrance gate at the site. The next step will be to apply a protective coating over the veneer.

In summer, the existing intake will be demolished. Once this is complete, the area will be landscaped.

Microtunnel at Jensen Road pathway – tunnel boring machine is installed

A second milestone was reached this week in Gladstone, with the tunnel boring machine being installed in the shaft. The machine is now set to begin boring a tunnel under River Road and McLoughlin Boulevard, working east to Exeter Street, and a 60 in. pipe casing will be inserted into the tunnel.

Large storage tanks to help separate the dirt and materials removed during microtunneling are set up at the site and along the side of River Road, near Jensen Road. Work hours are 7 a.m. – 6 p.m., Monday to Friday, and Saturdays, 9 a.m. – 6 p.m.

To maintain safety, there is a single lane closure on River Road at the Jensen Road pathway during the microtunnel work. Two lanes of traffic will be maintained. The Jensen Road pathway is also closed to pedestrians during construction. Please use Meldrum Bar Park Road to access the park.

Neighbors can expect to see and hear excavators, a hydraulic crane, trucks, a separation tank for the materials removal and generators. During construction, there may also be an increase in noise, truck traffic and vibration depending on neighbors’ locations.

Meldrum Bar Park pipeline work - pipeline installation through ballfield parking lot almost complete; paving in Meldrum Bar Park set to begin soon

Crews are making good progress with pipe installation through the ballfield parking lot, and have almost completed installing pipe to the corner of Jensen Road. Once the microtunnel work is complete, the remainder of the pipe on Jensen Road pathway will be installed. To accommodate equipment and maintain safety during construction, the ballfield parking lot is temporarily closed.

Next week, crews will be working on Meldrum Bar Park Road near the river, completing a connection from the new pipe to the existing 27-inch water pipe. Once this is complete, crews will prepare the ballfield parking lot and portions of Meldrum Bar Park Road for repaving.

Access to the park and boat ramp remains open during regular park hours. Please watch for flaggers in the work areas—single lane closures are in place during construction in the park. Neighbors and park users can expect to see and hear excavators, loaders, pipe, steel plates, gravel and dump trucks.

W. Exeter Street – equipment mobilized; pipe installation to resume

Crews have started mobilizing equipment to W. Exeter Street at Bellevue, and will begin installing pipe to the western end of W. Exeter Street next week. Traffic detours and temporary closures will be in place during work hours, usually one block at a time. Equipment and material will be stored and parked in the right-of-way along Exeter Street. Key information:

  • During work hours, there will be no on-street parking in the one block closure zone
  • 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 noise and truck traffic during construction.
