Station in Gladstone to draw less water than original plans -

Wondering about that large red crane that arrived last month in Gladstone? It will be used to demolish the old Clackamas River Intake Pump Station structure.

PHOTO BY: RAYMOND RENDLEMAN - The smaller pump station on the left will be destroyed starting July 1.Lake Oswego built a new pump station at the location with the plan of pumping water all the way to Tigard. The Oregon Court of Appeals decided in December that the state might have allowed Lake Oswego, Tigard and other water providers to draw too much water from the Clackamas River, threatening several species of fish. The court found that Oregon Water Resource Department’s final orders contained a finding of fact that was not sufficiently supported by evidence. The court remanded the orders back to the state to provide a more thorough explanation of how the conditions would protect fish.

Lake Oswego draws up to 16 million gallons a day from the Clackamas River for its own uses, but has permits from the state to draw up to 38 million gallons a day.

Lake Oswego officials say that the court’s decision does not diminish or reduce the water supply that would be available to Tigard through Lake Oswego’s water rights and the terms of the partnership agreement.

State agencies are mandating that the partnership reduce their withdrawals during certain months of the year, if natural streamflows fall below certain levels. In the event reduced withdrawals are required, Lake Oswego and Tigard have backup plans in place and can rely on over 450 million gallons of water stored in underground and above ground reservoirs, to supply water to Lake Oswego and Tigard residents.

Meanwhile construction is continuing, since officials say it would be costlier to stop work while the legal mess is sorted out. Tigard and Lake Oswego are having to look at possible backup plans, should they not be able to draw that much water from the river.

Crews have started preliminary work within the old pump station and around the deck, removing the pumps, pump columns and other mechanical equipment to begin its removal process on July 1.

This week, crews will begin removing its roof and creating walls. Then crews will move equipment to the river level — setting up a crane, mats, stair tower and scaffolding — at the new pump station's access bridge. Once this is complete, they will remove the deck of the old pump station.

Demolition is expected to take about two months. Crews will cut the concrete using a wire saw and break it into smaller pieces to be removed off-site 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 contractor will work 7 a.m. to 6 p.m. Monday through Friday, and occasional Saturdays. In observance of Independence Day, no work will take place on July 3 or 4.

Other construction

Preparation activities for paving have begun on Clackamas, Bellevue and Exeter streets with crews grinding portions of the asphalt last week on Bellevue Avenue. Final paving is expected to begin the week of July 6. Crews plan to start at the intersection of West Clackamas Boulevard and Portland Avenue, working west on West Clackamas toward Bellevue Avenue, then north along Bellevue and west along Exeter Street to the Barton Avenue intersection.

Crews are continuing to lay pipe along the Jensen Road pathway and are about halfway done, working east toward River Road. Crews expect to be at the intersection with River Road in mid-July.

Crews encountered some difficulties microtunneling the pipe under River Road and McLoughlin Boulevard. Moving forward, the contractor will use a different method to install the remainder of the pipe to connect to Exeter Street.
