Douglas Drive Bridge Seismic Retrofit Project

The City of Oceanside is undertaking the Douglas Drive Bridge Seismic Retrofit Project in Oceanside, California, to enhance the structural integrity of the bridge by extending full-height infill walls at piers 4 through 12, while also installing two fish passage flumes and a wildlife crossing to support ecological connectivity. The project requires temporary disturbance of Levee 3 and the San Luis River Trail, with full restoration to original conditions following construction. Environmental impacts are being mitigated through a comprehensive plan that includes establishing 0.07 acres of new freshwater wetlands, enhancing 0.02 acres of existing wetlands, restoring 0.26 acres of coastal sage scrub, eradicating invasive riparian vegetation from 0.04 acres, and implementing long-term management of a 2.28-acre mitigation site at El Corazon. Regulatory approvals have been secured under Fish and Game Code Section 1602 via the Lake and Streambed Alteration Agreement EPIMS-SDO-55909-R5, along with Clean Water Act Section 401 Water Quality Certification R9-2025-0161 from the San Diego Regional Water Quality Control Board, and compliance with CEQA through a Negative Declaration or Mitigated Negative Declaration. The project is administered under NAICS code 237310, with oversight provided by the California Department of Fish and Wildlife and the San Diego Water Board, while the City of Oceanside acts as the lead applicant and implementing entity. Contractual specifics such as value, payment terms, clause language, contract type, or solicitation deadlines are not articulated in the available documentation, and no formal FAR clauses, evaluation factors, or certification data from offerors are present; however, key contacts for environmental and project management have been identified, and inspection and acceptance authority rests with state and regional regulatory agencies at their San Diego offices.
