Mansfield/Baker Vineyard Conversion Project #04086-ECPA

Mansfield/Baker Vineyard Conversion Project #04086-ECPA

The proposed project is for earthmoving activity associated with the development of a new +/- 7.29 acre vineyard (5.3 net vine acres), including installation of erosion control measures on two parcels totaling +/- 40.24 (Mansfield parcel - 20 acres; Baker parcel - 20.42 acres) located on the east fork of Soda Canyon Road approximately 3,000 feet northeast of its intersection with the main Soda Canyon Road approximately 7 miles north of Silverado Trail and 5 miles northeast of the Town of Yountville. Grading would be limited to the proposed vineyard area. Spoils created from grading may be placed outside of setback areas to create a filter media or used as rock barriers which will be placed within the proposed vineyard blocks and not within vegetation retention areas or within stream setbacks. Water for the project would come from two existing wells (one on each parcel). There is existing deer fencing on the north, east, and west sidesof the project area. Additional deer fencing is proposed on the southern project boundary and along the northern edges of Block 3, 4, and 5 West. An erosion control plan (#04086-ECPA) has been prepared. Vineyard blocks would have 24-foot wide vineyard avenues around the perimeters. There would also be two bridges placed over two intermittent and a no-till cover crop with 70% coverage. No future projects are anticipated for this parcel.
