Morgan Territory Road Bridges 5.0 and 5.2 Replacement Project (Notification of Lake or Streambed Alteration, No. EPIMS-CCA-43825-R3)

The California Department of Fish and Wildlife has issued a Lake and Streambed Alteration Agreement for the Morgan Territory Road Bridges 5.0 and 5.2 Replacement Project, authorizing Contra Costa County Public Works Department to demolish and replace two existing bridges over Marsh Creek at Post Miles 5.0 and 5.2. The new structures will be single-span, one-lane reinforced concrete slabs with wingwalls at all four corners, supported by Cast-In-Drilled Hole pile abutments, and will feature a 16-foot-wide paved roadway consisting of a 12-foot travel lane and two 2-foot shoulders. A total of 538 feet of approach metal guard railing will be installed—338 feet at Bridge 5.0 and 200 feet at Bridge 5.2. The project includes repaving the bridge approaches, upgrading adjacent drainage systems, raising the roadway and bridge profiles, and extending the total bridge length by approximately 38 feet combined. Work is being conducted under a categorical exemption under California Code of Regulations Title 14, Sections 15301–15302, recognizing the project as a minor alteration to existing infrastructure with no significant environmental impact beyond what is permitted under state law. The project is located in Contra Costa County, California, with precise coordinates and assessor parcel numbers provided for each bridge site. Responsibility for execution lies with the Contra Costa County Public Works Department, located at 255 Glacier Drive in Martinez, while oversight and regulatory approval are held by the California Department of Fish and Wildlife, specifically Region 3 – Bay Delta. Primary point of contact for environmental compliance is Andrea Boertien, an Environmental Scientist at CDFW, and Joe Yee of the County Public Works Department serves as the project implementer. No federal procurement instruments, contract clauses, pricing data, or federal acquisition regulation provisions apply; the transaction is governed entirely by state environmental statutes and local public works procedures. No solicitation number, contract value, payment terms, or delivery conditions are specified, and no formal evaluation factors, representations, or certifications are included, as this is an environmental notification and exemption record under CEQA, not a federally regulated procurement. The project was filed and posted in September 2025, with no defined performance period or submission deadlines provided.
