Lake B Long Term Bank Stabilization Project (Notification of Lake or Streambed Alteration, No. EPIMS-ALA-44959-R3)

The California Department of Fish and Wildlife has authorized CEMEX Construction Materials Pacific, LLC to undertake bank stabilization work along the north bank of Arroyo del Valle adjacent to the Lake B mine pit at the CEMEX Eliot Quarry under Lake and Streambed Alteration Agreement EPIMS-ALA-44959-R3, executed pursuant to Section 1602 of the Fish and Game Code. The project involves removing approximately 2,600 cubic yards of temporary riprap and ecoblocks installed during prior emergency repairs and replacing them with 6,350 cubic yards of fill material and 9,000 cubic yards of new riprap to provide long-term bank stability. Additionally, three stone barbs will be constructed mid-channel to enhance fish habitat and encourage the natural re-establishment of riparian vegetation. Work is confined to three specific locations and is governed by applicable state environmental regulations, including a Class 2 categorical exemption under California Code of Regulations Title 14 Section 15302. The activity is not governed by federal procurement clauses or FAR requirements, as the agreement functions as a regulatory authorization rather than a formal contract with pricing, deliverables, or contractor representations. The place of performance is in unincorporated Alameda County, California, with oversight responsibility held by the California Department of Fish and Wildlife’s Region 3 - Bay Delta office in Fairfield. No contract value, payment details, or invoicing instructions are specified because the document is a permit notification, not a procurement instrument. The project was submitted as an EPIMS notification and is not subject to competitive bidding, evaluation factors, or standard Federal Acquisition Regulation structures. Point of contact for regulatory compliance and project oversight includes Jason Faridi, Senior Environmental Scientist Supervisor, and Craig J. Weightman, Environmental Program Manager, while Christine Jones represents CEMEX as the responsible party executing the work. The agreement is effective as of June 25, 2025, with no stated period of performance or delivery schedule, and no formal contracting officer’s representative or technical representative designations are provided.
