State Route 1 Lagunitas Creek Bridge Project

The State Route 1 Lagunitas Creek Bridge Project in Marin County, California, involves replacing the existing bridge at Post Mile 28.4 to 28.6 with a new three-span concrete structure designed to improve seismic resilience, enhance safety for all users, and accommodate widened roadways. The project includes extensive earthwork and stabilization efforts such as permeation grouting of approximately 360 cubic yards of liquefiable soils along the creek bank, installation of temporary construction trestles to minimize environmental disruption, construction of noise barriers, and modifications to drainage systems to protect aquatic resources. The California Department of Transportation, District 4, is the lead procuring agency with key administrative oversight through Ronald Sangalang and Cherry Zamora, while the California Department of Fish and Wildlife holds permitting authority under the California Endangered Species Act via Incidental Take Permit No. 2081-2024-054-03. All project activities are governed by strict compliance with the California Environmental Quality Act, including implementation of mitigation measures detailed in the certified Environmental Impact Report and the Mitigation Reporting Plan. The place of performance is clearly defined along SR-1 in Marin County, with all construction, inspection, and acceptance conducted on-site or through administrative review at Caltrans District 4 in Oakland. Although the estimated contract value, pricing structure, and detailed evaluation criteria are not disclosed, the solicitation number 2081-2024-054-03 and associated environmental approvals indicate active procurement underway with key milestones established for late 2025. Special contractual obligations center entirely on regulatory adherence rather than typical federal acquisition clauses, with no explicit FAR clauses, packaging requirements, payment details, or evaluation factors provided. The contract requires ongoing environmental monitoring, public record maintenance, and strict compliance with species protection and habitat mitigation protocols, making environmental stewardship a core performance requirement rather than a supplemental condition.
