EA 10-1F140_Alpine County - State Route 88 Post Mile 4.11 Culvert Replacement (Streambed Alteration Agreement EPIMS Notification No. ALP-62968-R2)

The California Department of Fish and Wildlife has authorized the California Department of Transportation to replace an existing 18-inch diameter, 65.9-foot-long corrugated metal pipe culvert at State Route 88, Post Mile 4.11 in Alpine County, with a 24-inch diameter reinforced concrete pipe featuring rubberized gasket joints, along with a new concrete flared end section at the outlet. This work is conducted under Streambed Alteration Agreement EPIMS Notification No. ALP-62968-R2, issued pursuant to Section 1602 of the Fish and Game Code, and is subject to modifications outlined in Amendment #1, which includes approval for temporary water diversion to enable construction outside standard work windows. Vegetation removal is limited to trimming and clearing riparian vegetation for construction access, including the removal of one mature willow shrub, with all activities designed to minimize environmental impacts. The project qualifies for categorical exemptions under California Code of Regulations Title 14, Sections 15302 and 15304, confirming it as a minor replacement and land alteration with no significant environmental effects. The work site is located at an unnamed tributary to Caples Lake, with performance and inspection occurring on-site. Oversight is shared between Caltrans District 10 as the project implementer and the California Department of Fish and Wildlife as the regulatory authority, with key contacts including Jason B. Miller for project execution and Samantha Morford for environmental compliance. No federal acquisition regulations apply to this agreement, as it functions as a state environmental permitting instrument rather than a federal procurement contract, and no pricing, payment terms, invoicing protocols, or contract clauses from the FAR are included. The NAICS code 237310 identifies the work as highway construction, though the contract value, delivery schedule, and detailed evaluation criteria remain unspecified in the available documentation.
