PROJECT DESCRIPTION: The USACE and the Cities have prepared a joint Final Environmental Impact Statement/Environmental Impact Report (EIS/EIR) to evaluate potential options for reducing storm damage related coastal erosion over a 50-year period anticipated to occur from 2018 through 2068.
The Authorized Project for coastal storm damage reduction in Encinitas includes construction of a 50-foot-wide beach fill along a 7,800-foot-long stretch of shoreline using 340,000 cubic yards of compatible sediment, with renourishment (in the amount of 220,000 cubic yards) every 5 years on average over a 50-year period of Federal participation, for a total of nine additional nourishments.
The Authorized Project for coastal storm damage reduction in Solana Beach includes construction of a 150-foot-wide beach fill along a 7,200-foot-long stretch of shoreline using 700,000 cubic yards of compatible sediment, with renourishment in the amount of 290,000 cubic yards every 10 years on average over a 50-year period of Federal participation, for a total of four additional nourishments.
Material for the beach fill will be dredged from borrow sites located off the coast of San Diego County. Physical monitoring of the performance of the project will be required annually throughout the 50-year period of Federal participation. This plan would provide coastal storm damage reduction throughout the project reach and would maintain the existing recreational beach. A comprehensive mitigation monitoring and reporting plan has been incorporated into the proposed project.
The Final Integrated Feasibility Study & EIS/EIR and Chief of Engineers' Report for the Encinitas-Solana Beach Coastal Storm Damage Reduction Project, San Diego County, California was signed 26 April 2016. The project was authorized for construction in the Water Infrastructure Improvements for the Nation Act of 2016. The authorized name is San Diego County, CA (formerly known and referred to as Encinitas and Solana Beaches, CA).
