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.
