Installation of Electric Shore Power Infrastructure by San Diego Unified Port District at Fish Harbor Pier and Chesapeake Wharf

The proposed project would involve the installation of electric shore power infrastructure at Fish Harbor Pier by the San Diego Unified Port District (District) in the city of San Diego, California. Fish Harbor Pier (Pier) has historically supported in-transit commercial fishing vessels and various cargo operations, and continues to do so. With the large quantity of vessels operating through the Pier, it is required that the standard mandating the installation of maintenance and shore power infrastructure, set by the California Air Resources Board (CARB), be met; however, the Pier’s existing electrical infrastructure does not support these mandated shore power requirements. Implementation of the proposed project would equip the Pier with the infrastructure necessary to support these CARB requirements. Work to specifically complete the proposed project would include: • Removal of four (4) multi-trunk paperbark trees • Installation of one (1) 480V-208V power center • Installation of three (3) receptacle pedestals • Retrofitting of existing electrical distribution system Paperbark Tree Removal The proposed project would involve the removal of four (4) multi-trunk paperbark trees (Melaleuca quinquenervia) from the landscaped area adjacent to Fish Harbor Pier where the proposed power center would be installed. To comply with tree replacement requirements, four (4) 24-inch box trees would be planted within proximity of Tuna Harbor. Installation of New 480V-208V Power Center The proposed project would involve the installation of a new 480V-208V power center in the landscaped area adjacent to Fish Harbor Pier and underground electrical feeder circuit to connect the new power center to the existing 480V service entrance switchboard located on the northeastern corner of the Chesapeake Fish Company parking lot. The spare 400A SDG&E meter switchboard section would be repurposed as the connection point for the electrical supply, and the underground power circuit for the 400A meter switchboard would be extended south and west to service the pier and wharf areas. Installation of the underground power circuit would be completed by trenching along the parking lots directly adjacent to the Chesapeake Fish Company leasehold from the existing switchboard to the pier. Installation of Receptacle Pedestals The proposed project would also involve the installation of three (3) receptacle pedestals along the north side of Fish Harbor Pier. Each pedestal would have two (2) receptacles: one (1) 100A/3PH receptacle and one (1) 30A/1PH receptacle. Retrofit of Existing Electrical Distribution System The existing antiquated electrical distribution system currently serving Fish Harbor Pier and Chesapeake Wharf would be removed and replaced with a new shore power electrical distribution system. Electrical wiring from the pier and wharf areas would be integrated into the new shore power electrical distribution system where possible. Additionally, conduits under and along the perimeter of Fish Harbor Pier would have their wiring removed and replaced. There would be no in-water components to the project, installation of any structures into the water below, or addition of fill or overwater coverage. Construction of the proposed project is anticipated to begin in the Fall of 2026, and would be carried out in two (2) phases over the course of approximately four (4) months. Phase 1 would involve the installation of a duct bank from the existing SDG&E switchboard to the Chesapeake Fishing Co. access driveway and associated installations, and would require staging of equipment in the parking lot directly east of the Chesapeake Fishing Co. leasehold. Phase 2 would involve the installation of a duct bank from Chesapeake Fishing Co. to the pier, the installation of the 208V power center, and the installation of shore power infrastructure on the pier, and remaining installations associated with the proposed project. Staging for Phase 2 would be moved from the east lot to the south lot following the completion of Phase 1. Phase 1 would take approximately one (1) month to complete, while Phase 2 would take approximately three (3) months. Work would be conducted Monday through Friday during the work hours of approximately 7:00 a.m. to 3:30 p.m. Construction of the proposed project would require partial closure of the promenade due to necessary trenching to connect the infrastructure installed on the pier to the adjacent power center. Trenching activities would consist of one (1) trench across the promenade from the adjacent parking lot towards Fish Harbor Pier. To minimize impacts on the promenade and maintain public access along the bayfront, construction would close the promenade one half at a time so that the public may walk on one side of the promenade while work would be conducted on the other. This partial closure would ensure public access and allow the public to continue using the promenade throughout the duration of the project. Trenching and construction on the promenade would take approximately one (1) month to finish for each half of the promenade, or approximately two (2) months total. Due to its nature and limited scope, construction of the proposed project would generate a minor amount of vehicle trips and would require limited use of equipment. Therefore, impacts related to air quality, greenhouse gas emissions, and transportation and traffic are not anticipated to occur. Furthermore, the District would be responsible for complying with all applicable federal, state, and local laws regarding construction demolition debris, hazards and hazardous materials, and stormwater.
