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 re-nourishment (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 re-nourishment 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. For the initial fill, sand would be dredged from an offshore source beyond depth of closure, using the SO-5 borrow site located offshore of San Dieguito Lagoon. The material would be placed hydraulically directly onto the two receiver sites within the Encinitas and Solana Beach project segments.
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 authorized 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 Record of Decision was signed on 22 June 2017. 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).
Preconstruction, Engineering and Design (PED) Phase
The project is currently in the preconstruction, engineering, and design (PED) phase that includes preparation of design documents, environmental compliance, real estate activities, and pre-project monitoring through to construction contract advertisement.
Pre-Project monitoring includes the following:
- Habitat Monitoring
- Rocky Reef Monitoring/Habitat Mapping
- Rocky Intertidal Monitoring
- Surfgrass Monitoring
- Borrow Site Monitoring
- Seabed Morphology
- Water Quality
- Benthic Habitat Quality
- Surf Zone Monitoring for Surfing
- Physical Beach Transects
Monitoring efforts are ongoing from Fall 2022 (September 1 through November 30) through Spring 2023 (April 1 through June 30).
