SUMMARY/DISCUSSION:
San Antonio Dam is under the jurisdiction of the California Department of Water Resources Division of Safety of Dams (DSOD). DSOD classifies San Antonio Dam for hazard to downstream population and infrastructure in the event of catastrophic failure as “Extremely High.” Prudent practice and California Water Code Regulations require dam owners under DSOD jurisdiction to collect and evaluate dam instrumentation data and to perform periodic dam inspections to ensure public safety. Instrumentation data collected from 85 piezometers, 10 observation wells, 34 drains and 21 survey monuments allow monitoring of seepage flows, embankment movement, and general stability of San Antonio Dam.
AECOM Technical Services, Inc., has significant experience conducting stability performance evaluations and safety inspections of dams, and has extensive knowledge of San Antonio Dam. The purpose of Amendment No. 3 is to continue providing these engineering services for San Antonio Dam. The Scope of Work listed in Exhibit E, of the Agreement covers the dam performance evaluation tasks to meet DSOD regulatory monitoring requirements.
