The City of Norfolk, Department of Utilities, owns four water supply dams. GEI performed dam safety evaluations addressing embankment slope stability and seepage stability; spillway and intake tower conditions and stabilities; and capacity to safely pass the Spillway Design Floods (SDFs).
GEI provided engineering services to the San Diego County Water Authority to support the permitting efforts for the Authority’s Emergency Storage Project (ESP). As the prime engineering consultant, GEI’s scope of services included investigating a wide range of potential alternatives to meet the County’s water needs should an earthquake sever the water supply arteries that bring 90 percent of the County’s water from the State Water Project and the Colorado River Aqueduct.
