EA 01-0J93U_SR 29 PM 15.26-18.43 Twin Lakes CAPM & Left Turn Channelization (Streambed Alteration Agreement EPIMS Notification No. LAK-57517-R2)

The California Department of Fish and Wildlife has authorized a streambed alteration agreement for culvert replacement and associated roadway maintenance work along State Route 29 in Lake County between post miles 15.26 and 18.43, under EPIMS Notification No. LAK-57517-R2. The project includes upsizing an 18-inch by 70-foot corrugated steel pipe to a 24-inch by 70-foot pipe at PM 15.26 with installation of a steel flared end section and rock slope protection at the outlet, in-kind replacement of a 24-inch by 88-foot corrugated steel pipe at PM 16.44, and in-kind replacement of a 24-inch steel flared end section at PM 18.43. Vegetation management will be conducted using hand tools or heavy equipment, with strict limitations to ensure heavy machinery remains confined to the roadway prism and does not enter stream channels or riparian zones. Temporary dewatering or clear water diversions may be implemented as needed to facilitate in-channel construction where water is present. The work falls under a categorical exemption under California Code of Regulations Title 14, Section 15301, as it involves repair and replacement of existing facilities consistent with current design and functional standards. Authorization is issued under Section 1602 of the Fish and Game Code, ensuring compliance with environmental protections for aquatic resources. Performers of the work, represented by the California Department of Transportation, must adhere to all conditions outlined in the agreement and conduct activities to maintain environmental integrity. The project is administered by the California Department of Fish and Wildlife, Region 2 – Northern Central, with oversight provided by Senior Environmental Scientist Mary Xiong and project coordination handled by Caltrans representative Isral Konopa. The agreement was executed via DocuSign on October 6, 2025, and the notice was posted on November 13, 2025. No formal contract value, pricing structure, or federal acquisition regulation clauses are specified, as this is a state-level environmental authorization rather than a federally procured contract. There are no stated deadlines for performance, no FOB or payment terms, no formal contract type designations, and no solicitation-based evaluation factors or offeror certifications included in the documentation. Inspections and acceptance occur at the three project locations, with the California Department of Fish and Wildlife serving as the approving authority. Packaging,
