San Luis Obispo, California — The City of San Luis Obispo (City) successfully completed the Mid-Higuera Bypass Project, marking a significant milestone in reducing storm-related flood risks while restoring the ecological health of San Luis Obispo Creek. Following its completion, the Mid-Higuera Bypass Project was recognized by both the American Society of Civil Engineers San Luis Obispo Branch (ASCE SLO) and the American Public Works Association Central Coast Chapter (APWA CC), receiving APWA CC’s Project of the Year award in the Structures ($5–25 Million) category and ASCE SLO’s Outstanding Flood Management Project award.

Located between Marsh Street and Madonna Road, the project provides increased flood capacity through bypass channel excavation, sediment removal, vegetation management, and replacement of the Bianchi Lane Bridge, addressing erosion and improving performance during high-flow storm events. Additional elements of the project included demolition of an existing bridge and structure, and proper handling and disposal of deposited lead in the air.

The project delivers key environmental benefits, including removal of invasive species, installation of native vegetation, and improvements to in-stream habitat. Work within the creek corridor required careful coordination with regulatory agencies to protect sensitive resources and comply with requirements and restricted work windows.

Cannon provided construction management and inspection services, supported by Earth Systems for materials testing and specialty inspections, and environmental oversight by SWCA.

The project was funded by City Water Funds, County Zone 9 Funds, and the State Water Resources Department. The Mid-Higuera Bypass Project reflects a strong partnership focused on resilient infrastructure, environmental stewardship, and long-term community benefit.

Congratulations on the completion of a project 20 years in the making!
