McCormack-Williamson Tract Levee Modification and Habitat Restoration Project – Phase B, SEIR Addendum No. 1

The California Department of Fish and Wildlife has amended Lake and Streambed Alteration Agreement EPIMS-SAC-45649-R3 to revise avoidance and minimization measures for the protection of the threatened giant garter snake as part of the McCormack-Williamson Tract Levee Modification and Habitat Restoration Project, Phase B. The amendment, approved on August 5, 2025, and posted on August 6, 2025, is led by Reclamation District 2110 as the project applicant and implemented within a defined area bounded by the Mokelumne River, Snodgrass Slough, Lost Slough, and Dead Horse Cut in Sacramento County, California. Environmental compliance is governed by the California Environmental Quality Act and Fish and Game Code section 1602, with the California Department of Fish and Wildlife acting as the responsible agency to ensure adherence to regulatory conditions outlined in Title 14 of the California Code of Regulations. No federal acquisition regulation clauses, procurement contracts, or financial terms are applicable, as this is a regulatory permitting action rather than a competitive procurement. Key personnel include Chad Fien of Reclamation District 2110 as the lead agency contact and Christina Autry of CDFW as the environmental scientist overseeing compliance. The project does not include a specified period of performance, cost estimates, invoicing procedures, or formal inspection protocols beyond environmental compliance requirements. There are no awarded contract values, payment details, procurement types, or socioeconomic certifications associated with this action, as it functions solely under California environmental and fisheries law.
