GP: Agricultural Watershed & Open Space (AWOS)
Z: Agricultural Watershed (AW)
The proposed project includes earthmoving, clearing of chaparral and installation and maintenance of erosion control measures associated with the development of + 24 acres of new vineyard (21.4 net vine acres), located within a 40-acre parcel located on the west side of Debb-Knief Road (private road) approximately one and three-quarter miles north of Soda Canyon Road, approximately six miles north of its intersection with Silverado Trail. Access to the project site would be from these roads. The parcel is located in an Agricultural Watershed (AW) zoning district, with a Napa County General Plan designation of Agriculture, Watershed and Open Space. Rock spoils created from grading would be used on the main access road (Debb-Knief Road) within the parcel. Existing slopes range from 4% to 16%, with an average of 10% slope. Water for the project would come from an existing well at the northeast corner of the parcel. An erosion control plan (#03522-ECPA) has been prepared. Erosion control measures include straw mulch, straw wattles, straw bale sediment barriers and a no-till cover crop with 80% coverage. Deer fencing would be placed only around vineyard blocks. Chemicals used for fertilizing and eradicating of weeds, pests and fungi would be kept in an existing shed located off-site. No future projects are anticipated for this parcel at this time.
