Project Information

Serrano Creek is a tributary to San Diego Creek which flows into Upper Newport Bay. Over the past decades, prior to implementation of the creek stabilization projects in 2001 and 2002, Serrano Creek had suffered substantial channel and bank erosion, resulting sediment deposition in Upper Newport Bay, degrading riparian habitat along the creek, and threatening homes, infrastructure and recreational resources along the creek.

Serrano Creek Stabilization Project evolved out of a multi-year planning process and collaboration between the County of Orange, City of Lake Forest, the Serrano Creek Conservancy, community members and federal and state regulatory agencies; and was designed to balance flood management, habitat and recreation objectives.

The project included rock grade stabilization structures, rock bank protection and other bio-engineering techniques like GeoWeb bank protection, Rock vanes, bendway weirs and extensive replanting of creek edges and banks.

Cost: $2.2 million
