Repairing Port San Luis Harbor’s breakwater

USACE is requesting comments on the Draft Environmental Assessment for the Port San Luis Harbor Operations and Maintenance breakwater repair project, located in San Luis Obispo County, California.

The USACE Los Angeles District is the lead federal agency for this project.

The breakwater was originally constructed between 1889 and 1913 to protect the inner bay, harbor, and small craft marine facilities from heavy surf and wave action approaching from the west.

The Proposed Action is to repair the breakwater using approximately 60,000 tons of new rock and resetting of approximately 29,000 tons of existing rock.

Approximately 15,000 cubic yards of uncontaminated, sandy material would be excavated adjacent to the breakwater to provide access for construction equipment.

The Proposed Action also includes measures to offset impacts to eelgrass beds that would be affected by excavation and breakwater repair activities, by restoring habitat within the work limits and other surrounding areas.

The breakwater was originally constructed between 1889 and 1913 to protect the inner bay, harbor, and small craft marine facilities from heavy surf and wave action approaching from the west.

According to USACE, the proposed breakwater repair will maintain safe navigability within the port.
