Tree pruning starting soon at the WR1 site

Waluga Reservoir 1 Roof Replacement Project Update

Design update

Design and permitting for the Waluga Reservoir 1 (WR1) roof replacement has been underway and is almost complete. As this project is a replacement of the WR1’s existing roof and the overall design of the new roof is similar in shape and size to the current roof, the project is exempt from land-use review. The roof replacement is considered maintenance and the new roof design is consistent with prior land-use approvals.

There will be no change to the color or size of the current reservoir. No trees will need to be removed to facilitate construction of the WR1 roof and columns. However, one tree has been identified as dead and has been approved for removal by the City of Lake Oswego. To enable safe removal and replacement of the roof, tree pruning will need to occur on existing trees located around the perimeter of the reservoir.

Over the next few months, the bidding process will take place to secure a contractor. Construction is expected to begin fall 2016, and take approximately six months.

Tree pruning starting soon

In early July, workers will begin pruning trees located around the WR1. Tree branches located approximately 10 ft. above and around the perimeter of the reservoir roof will be pruned and trimmed. This work is expected to take 1-2 days to complete. A certified arborist will be on site to monitor the pruning.

Neighbors can expect to see and hear a crew of workers, a wood chipper, chain saws, a wood chipper and dump trucks to haul wood chips and debris off site. Crews and equipment will access the site from 4800 Carman Drive. Generally, work hours will be Monday – Friday, 8 a.m. - 5 p.m. No work will take place on July 4. Tree pruning will be completed by a local Lake Oswego Company, Tree Care Unlimited.

The importance of WR1

WR1 is a crucial component to the Partnership’s system to provide drinking water to Tigard and Lake Oswego residents. Both Waluga Reservoirs (1 and 2) work together in tandem to store and provide clean, drinking water for both communities. Once the roof is replaced, WR1 is expected to provide safe, reliable water storage for at least 50 years.
