York Creek Vineyards LLC Olive Orchard Conversion

The York Creek Vineyards LLC Olive Orchard Conversion project, managed by Napa County Planning, Building and Environmental Services, involves the conversion of approximately 27.7 gross acres (21.4 net acres) of existing olive and fruit orchards and gardens into a vineyard. Located at 3601 Langtry Road within the York Creek Drainage of the Napa River Watershed, the project requires the removal of non-native grassland and existing trees, grading, and the installation of vineyards. The scope includes earthmoving activities and the implementation of an Agricultural Erosion Control Plan approved on November 24, 2025, in accordance with Napa County Code Chapter 18.108. The project is situated on moderate to steeply sloped terrain, with slopes ranging from 14% to 36%. All activities must remain within the footprint of existing agricultural uses as of June 16, 1993. To ensure environmental compliance, the project is exempt under CEQA Section 15301 Class 1 and must avoid impacts on cultural resources, native bees, northern spotted owls, and nesting birds and raptors. The lead agency contact for this effort is Planner III Pamela Arifian.
