Temporary Berthing Trailers by BAE Systems at BAE Systems Leasehold

The proposed project would involve the temporary installation of modular trailers by BAE Systems San Diego Ship Repair, Inc. (Applicant) to support a U.S. Navy ship’s crew while berthed at the Applicant’s leasehold in San Diego, California. The objective is to provide temporary structures adjacent to the ship in order to meet operational standards for the approximately one-year duration of the ship's stay. In lieu of operating from the ship while it is at berth, the crew would operate from the temporary trailers for the extent of the ship’s berth. The project is necessitated by U.S. Navy duty requirements for crew to remain on watch and in close proximity to ships while berthed. As such, the ship’s crew would be on duty while utilizing the trailers. The project area where the trailers would be located is an existing vacant space in the Applicant’s leasehold covered in asphalt. Work to specifically complete the proposed project would involve the delivery, placement, and the connection to existing utilities of ten (10) modular trailers measuring approximately 8 feet by 20 feet. All trailers would be equipped with internal utility systems, including lighting, HVAC, plumbing, and electrical infrastructure and would require connection to existing electrical, potable water, and sewer systems available at the facility. No additional infrastructure would be needed for utility support and no trenching would be required. Mobilization equipment will include trucks for transport, cranes, a forklift and hand tools. The combined trailers are expected to support up to approximately 30 crew members and would remain on site, with trailer operation anticipated to begin in Summer 2026. The trailers would be removed from the site following the U.S. Government ship’s departure, which would be after approximately one (1) year. 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 Applicant would be responsible for complying with all applicable federal, state, and local laws regarding construction demolition debris, hazards and hazardous materials, and stormwater.
