Clackamas River Water (CRW) is underway with plans to implement an eight-year, $40 million capital improvement plan known as the "Backbone Projects". These improvements will greatly enhance overall water quality and distribution, increase system pumping efficiencies and improve provision of water for fire emergencies. The project will connect the CRW treatment plant and northern distribution system to our south service area customers via a new reservoir at 152nd Avenue, water transmission mains, and pump stations. All of these investments will be made possible through municipal bonding.
One element of the Backbone Projects program will be to construct a new 6 million gallon, partially buried concrete reservoir and associated improvements at the District's 152nd Avenue Reservoir site, located west of 152nd Avenue and Louise Lane, just north of Highway 212/224. The finished reservoir will be mostly buried so that only the concrete roof and upper wall section is visible at ground level for minimal site distance impacts.
Preliminary engineering and design plans for the reservoir are currently underway and should be completed by June 2017. Final design and permitting will take place later this summer and be complete by Fall 2017. Construction is anticipated to begin in March, 2018 and take approximately 18 months to complete. The public will be invited to participate in two community open houses: one in June 2017 to provide input on the design plans and construction impacts; and another in March 2018 to meet the contractor and learn about detailed construction activities.
The project will require major earthwork activities during construction and will produce daytime noise and dust. The reservoir site will be fenced off from unauthorized access.
There may be delays on local roadways; however, most construction activity will be limited to the reservoir site after initial excavation and final grading activities. Flaggers will direct traffic around construction related equipment. Design and construction efforts will be made to minimize impacts as much as possible.
All project construction activities will comply with requirements of the applicable governing jurisdiction, including permitting, traffic control, noise and dust abatement, hours of work, and other elements.
