Arroyo Grande Creek Waterway Management

In response to historic flooding, the County of San Luis Obispo endeavored to modify the lower three-mile reach of the Arroyo Grande Creek waterway. Their goals were to increase the creek’s capacity, provide enhanced flood protection for 10-year storm events, enhance water quality, and maintain a healthy habitat for sensitive species. The County selected Cannon to provide civil, structural, survey, and construction management services.

Cannon’s efforts incorporated levee modifications and armoring, floodwalls, vegetation management, sediment removal, habitat enhancement, and other improvements necessary to protect the nearby residents of Oceano. We also developed a phasing plan and construction schedule, assisted during the bidding phase, and provided engineering support during the project’s construction.
