230 Long Ranch Road LLC Vineyard Development Agricultural Erosion Control Plan #P24-00114-ECPA

The 230 Long Ranch Road LLC Vineyard Development project, identified by Agricultural Erosion Control Plan #P24-00114-ECPA, involves the development of a vineyard on a 48.42-acre property in St. Helena, California. Approved by the Napa County PBES Director on June 8, 2026, the scope of work includes clearing vegetation, earthmoving, and land contouring to develop approximately 14.8 to 18.8 gross acres of vineyard, consisting of four vineyard blocks with approximately 12.1 to 15.8 net planted acres. The project specifically addresses land disturbing activities on slopes greater than 5% and requires strict adherence to erosion control measures to ensure no net increase in soil loss or runoff. Environmental compliance is a central component of the contract, governed by the California Environmental Quality Act (CEQA). A Mitigated Negative Declaration was adopted following a public review period from November 27 to December 27, 2025. Key environmental mandates include the retention of at least 3.0 acres of chamise alliance habitat and the preservation of 4.1 acres of Scrub Interior Live Oak habitat. The project also requires preconstruction surveys for nesting birds, protection of special-status plant species, and a three-year monitoring period for any replaced vegetation. Technical adequacy has been verified by the Napa County Engineering Division, and the project is subject to a specific grading season from April 1 through September 15. Administration of the project is handled on a time and materials basis, with the Napa County Planning Division overseeing inspections of fencing and habitat preservation before earthmoving begins.
