Spring Mountain Road Vineyard Agricultural Erosion Control Plan Track I (P25-00194-ECPA)

The project involves land disturbing activities on slopes exceeding 5 percent within a 40.81-acre parcel in St. Helena, California, specifically to develop approximately 5.8 gross acres of vineyard with 3.96 net planted acres distributed across three vineyard blocks. This includes clearing native chaparral and oak woodland within defined limits, earthmoving and reshaping the land’s contour, and implementing comprehensive erosion and runoff control measures alongside agricultural infrastructure necessary for vineyard operations. The work is governed by an Agricultural Erosion Control Plan under Track I, designated as P25-00194-ECPA, and is subject to regulatory oversight to ensure compliance with environmental and land use requirements. Primary point of contact for the project is Dana Morrison, Supervising Planner at Napa County, with additional support from Hannah Spencer, Planner III, and Daniel Byrne, Engineer of Record. The forecasted posting date is July 2, 2026, and the place of performance is located in the 94574 zip code area. All activities must align with local regulations to mitigate ecological impacts from land clearing and grading, with strict emphasis on controlling sedimentation and stormwater runoff to protect surrounding watersheds and natural resources. The plan requires ongoing maintenance of erosion controls throughout the construction and establishment phases of the vineyard.
