View Acres Seismic Upgrade Project, Oak Lodge Water District
We performed a structural seismic analysis of two 2.8-million-gallon, ground-supported steel water reservoirs at their View Acres site, built in 1966 and 1989. The structural evaluations found that both reservoirs were at risk for uplift and overturning during a current code-prescribed earthquake. The 1989 reservoir also required foundation modifications to avoid soil failure during an earthquake. RH2 designed upgrades to bring the two reservoirs up to the current code and safeguard them against a seismic event that could cause catastrophic failure and interrupt critical services to the area.
