River Intake Pump Station (RIPS) – major demolition set to begin July 1

The large red crane arrived last week, which will be used to demolish the existing RIPS structure.

Crews have started preliminary work within the existing RIPS structure and around the deck, removing the pumps and pump columns and other mechanical equipment (pictured above).

Next week, crews will begin removal of the existing RIPS roof and laying walls down. Beginning July 1, crews will mobilize equipment to the river level—setting up a crane, mats, stair tower and scaffolding—at the new RIPS access bridge. Once this is complete, they will remove the deck of the existing RIPS.

Demolition is expected to take about two months. Crews will sawcut the concrete using a wire saw and break it into smaller pieces to be removed offsite and recycled. Neighbors will notice an increase in noise, truck traffic and potential vibration during this work. Once demolition is complete, the area will be landscaped.

The RIPS contractor will be working Monday to Friday, 7 a.m. – 6 p.m., and occasional Saturdays. In observance of Independence Day, no work will take place on July 4.

W. Clackamas, Bellevue and Exeter Street – paving preparation begins

Preparation activities for paving have begun with crews grinding portions of the asphalt this week on Bellevue Avenue (pictured above). Final pavement placement is expected to begin the week of July 6. Crews plan to start at the intersection of W. Clackamas Boulevard and Portland Avenue, working west on W. Clackamas toward Bellevue Avenue, then north along Bellevue and west along Exeter Street to the Barton Avenue intersection. Work hours are 7 a.m. – 6 p.m., Monday to Friday.

During asphalt grinding and paving, there will be periods where roads are temporarily closed to all traffic, so the new pavement can dry. Residents located along the pipeline alignment will receive a door hanger or notice 48 hours prior to the scheduled paving on their street. Please find an alternative place to park on a side street or prepare to leave your house before the paving begins on your street.

There will be no pipeline construction or paving work on Friday, July 3 or Saturday, July 4 in obeservance of Independence Day.

Jensen Road pathway – pipe installation continues

Crews are continuing to lay pipe along the Jensen Road pathway and are about halfway done, working east toward River Road. Work hours are 7 a.m. – 6 p.m., Monday to Friday. Crews expect to be at the intersection with River Road in mid-July.

Neighbors can expect to see and hear excavators, loaders, pipe, steel plates, gravel and dump trucks. During work hours, there may be an increase in noise, truck traffic and vribation, depending on neighbors’ locations. Trucks and equipment will enter and exit the pathway from both River Road and Meldrum Bar Park. To maintain safety, the pathway will remain closed during construction.

Crews encountered some difficulties microtunneling the pipe under River Road and McLoughlin Boulevard. Moving forward, the contractor will use a different method, likely traditional cut-and-cover trenching, to install the remainder of the pipe to connect to Exeter Street. More information will be provided as it becomes available regarding this work
