the development and subsequent operation of approximately 3-acres of
new vineyard (±2.5 net plated acres) with the following
components/characteristics: i) Earthmoving and grading activities that
include vegetation and tree removal, soil ripping (maximum depth of 48
inches), grading of approximately 500 cubic yards of cut and fill (balanced
on-site) for land contouring, rock removal, disking, and the development
or erosion control measures; ii) Temporary erosion control measures that
include cover crop, straw wattles, erosion control blankets, and application
of straw mulch at a rate of 3,000 lbs. per acre; iii) Permanent erosion and
runoff control measures that include cross slope diversion ditches and
subsurface drainlines to an existing level spread, outsloped vineyard
avenues, water bars and rolling dips, and establishment of a permanent
no-till cover crop maintained at a minimum vegetation cover density of
80%: vineyard avenues will also maintain a minimum cover density of
80%; iv) Installation of vineyard trellis and irrigation system, and planting
rootstock on a 6-foot by 4-foot spacing pattern for a vine density of 1,815
vines per acre: the vineyard irrigation source would be from the existing
onsite well. V) Ongoing operation and maintenance of the vineyard, which
includes vine management (pruning, fertilization, and pest and disease
control), weed control, cover crop mowing, irrigation and trellis system
maintenance, and fruit harvesting. The management regime of the no-till
cover crop would consist of mowing and late winter or early springtime
strip spraying in an 18-inch-wide strip by contact or systemic herbicides:
no pre-emergent spraying would be utilized as part of cover crop
management.
