Service Description: Relic sediment deposits within the Goleta Slough, Carpinteria Salt Marsh, Ormond Beach wetlands, and Mugu Lagoon contain unknown reserves of sand that may present opportunities for one time or more regular beach nourishments. The Goleta Slough is already being regularly dredged by Santa Barbara County to remove significant volumes of sediment that accumulates within the slough channels. The feasibility of extracting beach compatible sand from the other environmentally sensitive areas is subject to further study and review. Debris basins have been built within critical watershed pathways to provide flood protection for developed areas downstream. However the barriers trap sediments that would otherwise be naturally carried downstream to the shoreline. A number of these structures exist throughout Santa Barbara and Ventura Counties. The barriers typically trap mixtures of sand, silt, clay and other debris that periodically requires removal to restore flood storage capacity of the basin. Locations compiled by Noble Consultants for the Shoreline Survey and updated for BEACONs Coastal Regional Sediment Management Plan. Submitted to CSMW as part of the Central Coast (from Pt. Conception to Pt. Mugu) Coastal Regional Sediment amanagement Plan (2009).

Comments: Relic sediment deposits within the Goleta Slough, Carpinteria Salt Marsh, Ormond Beach wetlands, and Mugu Lagoon contain unknown reserves of sand that may present opportunities for one time or more regular beach nourishments.

The feasibility of extracting beach compatible sand from the other environmentally sensitive areas is subject to further study and review. Debris basins have been built within critical watershed pathways to provide flood protection for developed areas downstream.
