Llamas Stream Crossings Project (Notification of Lake or Streambed Alteration, No. EPIMS-MEN-56504-R1C)

The Llamas Stream Crossings Project, identified by Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-MEN-56504-R1C, is an agreement between the California Department of Fish and Wildlife and Miguel Llamas. Executed pursuant to Section 1602 of the Fish and Game Code, the project is located in Mendocino County within the Russian River watershed, specifically at Assessor's Parcel Number 047-310-12. The project is categorized as a special notice under NAICS code 237990 and was approved via a Notice of Exemption on January 15, 2026, based on categorical exemptions Classes 1, 2, and 4 of the California Code of Regulations. The scope of work is limited to a single encroachment to upgrade an existing culvert. This process involves the excavation and removal of the old culvert, replacement with a new properly sized culvert, backfilling, compaction of fill, and the application of rock armoring to prevent erosion. Technical specifications require the installation of a riprap energy dissipator apron below the culvert outlet using median 9-inch diameter angular rock armoring, with a width two times the pipe diameter and a length three times the pipe diameter. Primary administrative oversight is managed by John Herrera, Senior Environmental Scientist Specialist with the California Department of Fish and Wildlife.
