Tanks and Reservoirs
City of Portland – Forest Park Low Tank – Utility Extension
Construction of a fully buried 76’ diameter 1.3 million gallon (MG) pre-stressed concrete reservoir located within a heavily residential Scenic Resource Zone along NW Skyline Boulevard in Portland, OR. This project required over 30,000 CY of excavation, reservoir base prep, and backfill with associated excavation support systems to perform excavation with a site that required cuts of up to 50’ from original ground to subgrade elevation at reservoir floor.

This project included construction of a 140-foot diameter 2.3 million gallon partially buried pre-stressed concrete reservoir and an associated 1,900 square foot control building. The control building housed valves, and flow meters required for the operation of the reservoir as well as a 1,200 gpm duplex booster pump station. A seismically activated valve isolation system was also constructed. Over 40,000 CY of excavation was required for this project, with over 2,000 CY of it being large boulders and solid rock.
