203 Pavement

The project involves comprehensive roadway improvements along State Route 203 in Mammoth Lakes, California, from post mile L0.0 to R8.7, with objectives centered on pavement preservation, shoulder stabilization, drainage restoration, guardrail replacement, curb ramp upgrades, and the installation of a new radar speed feedback sign. Work will include pavement rehabilitation with new striping, rumble strips, and widened shoulders at three locations—two featuring 4-foot bicycle lanes and one an 8-foot standard shoulder—to enhance safety and accommodate multimodal traffic needs. Culverts will be upgraded with flared ends and rock slope protection, and cut slopes will be laid back to meet current engineering standards. All construction must adhere strictly to the Caltrans 2024 Standard Specifications and comply with environmental regulations under CEQA and NEPA, including mitigation measures for biological, hydrologic, and cultural resources. The project is scheduled for a 140-working-day duration with an anticipated start date in 2029, though no final contract value or detailed pricing structure is available in the documentation. The place of performance is clearly defined as the designated segment of SR 203 in Mono County, with inspections and acceptance conducted on-site by Caltrans. Before construction, the contractor must secure critical environmental permits including a Section 1602 Streambed Alteration Agreement from the California Department of Fish and Wildlife, a Section 401 Water Quality Certification from the Lahontan Regional Water Quality Control Board, and a Programmatic Biological Opinion from the U.S. Fish and Wildlife Service. Additional compliance with Section 4(f) of the Department of Transportation Act requires concurrence from the U.S. Forest Service. The contracting authority is Caltrans District 9 in Bishop, with Rebeka Riesen serving as the Contracting Officer Technical Representative (COTR) and Wendy Campbell as the Contracting Officer. Proposals must be submitted via email to rebeka.riesen@dot.ca.gov by February 19, 2026, to the Caltrans office in Bishop, California. While the solicitation is classified as a forecast with a NAICS code of 237310 for heavy and civil engineering construction, no information is provided regarding set-asides, socioeconomic preferences, or source selection criteria. The contract lacks formal federal contract clauses, packaging and marking requirements, invoicing details, or payment system specifications, indicating reliance on Caltrans state-level administrative protocols rather than full federal acquisition regulation frameworks.
