EROSION & SEDIMENT CONTROL PLAN
Erosion and Sediment Control Narrative For:
6640 Markwood Rd.
TM 8 Parcel 50
Albemarle County, VA
HUC: BUCK MOUNTAIN CREEK 020802040201
LAT: 38' 12' 49AN LONG: 78' 33' 00"W
Project Description: The proposed work involves the construction of a new
production winery building at an existing vineyard. The project area is at the
end of an existing farm road on a property at the intersection of Markwood
Rd and Davis Shop Rd. The total area of the parcel is 70 acres. The total
on-site disturbed area is approximately 0.88 acres. Work is anticipated to
begin in late Spring of 2018.
Erosion control measures shown will protect the stream and property below
from receiving silt -laden runoff.
Existing Site Conditions: The project site area is in an open pasture and
generally slopes to the northeast at 10 to 15%. The pre and post drainage
patterns will be the some.
Adjacent Property: The property is surrounded by other large acreage farms
and wooded areas.
Off-site Areas: No off-site areas will be involved in this project.
Soils: 81 C-Thurmont loam, loamy, 0.32 K -Factor, Group B soil
36B-Hayesviile loam, loamy, 0.28 K -Factor, Group B soil
Critical Erosion Areas: There are no critical erosion areas in the project area.
Soil Stockpiles: Temporary soil stockpiles will be utilized during the excavation
of the building foundations.
Erosion and Sediment Control Measures:
Unless otherwise indicated, all vegetative and structural erosion and sediment
control practices will be constructed and maintained according to minimum
standards and specifications of the Virginia Erosion and Sediment Control
Handbook. Additional measures may be required duriing construction by the
Erosion Control Inspector, as needed.
Structural Practices:
Construction Entrance: (CE) 3.02 (To be installed where construction site traffic exits
the project area, to remove soil from tires prior to travel on public roads. The contractor shall
clean and maintain the travelway as required to keep soil froin washing into unprotected areas
and to provide a safe surface for pedestrian and vehicular access. Die Construction Entrance
will be located within thefootprint of the existing building to protect the adjacent paved
travelways. Once the building is erected, all adjacent areas will be stabilized and the
construction entrance will no longer be necessary.)
Silt Fence: (SF) 3.05 Silt fence (wire -supported) shall be constructed along
the lower limit of graded areas. (To be installed as showtrt on the plan, down -gradient of
disturbed areas created by the proposed work, and above the proposed excavation to prevent
up -gradient runoff from crossing disturbed areas. )
Level Spreader (LS) 3.21 An outlet for dikes and diversions consisting of an
excavated depression constructed at zero grade across a slope to convert
concentrated, sediment free runoff to sheet flow and release it into areas of
undisturbed soil which is stabilized by existing vegetation. (To be installed at the end
of the roof drains to disperse concentrated runof,.)
Permanent Seeding (PS) 3.32 Establishment of perennial vegetative cover by
planting seed where permanent, long-lived vegetative cover is needed on
fine -graded areas. (Permanent seeding will be provided on all disturbed areas designated to
be landscaped on the site plan within 7 days of final grading.)
Mulching (MU) 3.35 Application of plant residues to disturbed surfaces to
prevent erosion and reduce overland flow. Apply to all seeded areas. Refer to
Table 3.35-A on Sheet C-3.3 for application rates. (To be installed along with
Permanent Seeding)
Dust Control (DC) 3.39 Reducing surface and air movement of dust during
land disturbance, demolition or construction activities in areas subject to dust
problems in order to prevent soil loss and reduce the presence of potentially
airborne substances. (To be installed, if required by the Courrtty, where disturbed soil is to remain
unprotected for an extended period. )
Vegetative Practices:
Temporary Seeding 3.31: All areas disturbed by construction that will not be
brought to final grade for a period of more than 14 days, will be stabilized
by establishing a good stand of grass.
Lime 3.31: Unless it is known that the site will rtemain undisturbed for
many months, lime is not necessary. If necessary, the amount will be
determined by Soil Test, or 3 tons per acre of pulverized agricultural
limestone, uniformly applied to surface to be seeded during seedbed
preparation and incorporated into the top 2-4 inches of soil.
Fertilizer 3.31: 600 pounds per acre of 10-20-10 or equivalent, uniformly
applied to the surface to be seeded during seedbed preparation and
incorporated into the top 2-4 inches of sail.
Surface roughening 3.31: Where disturbed soils have been compacted,
loosen soils by discing, raking, or whatever acceptable means available to
receive seed.
Seed 3.31: Seed shall be broadcast evenly and planted from 14 to X inch
deep. Seasonal seed selection shall be as follows:
• Sept. 1 - Feb. 15: 50/50 Mix of Annual Rye and Winter Rye, 50-100
Ib/ac.
• Feb. 16 - April 30: use Annual Rye, 60-100 Ib/ac.
• May 1 - Aug. 31: use German Millet, 50 Ib/ac.
Areas which fail to establish vegetative cover adequate to prevent rill erosion
will be reseeded as soon as such areas are identified.
Management Strategies: Construction should be sequenced so that grading
operations can begin and end as quickly as possible. Areas that are not to
be disturbed shall be clearly marked by the placement of the erosion control
measures prior to construction. The job superintendent shall be responsible for
the installation and maintenance of all erosion and sediment measures.
Where construction vehicle access routes intersect paved public roads,
provisions shall be made to minimize the transport of sediment by vehicular
tracking onto the paved surface. Where sediment is transported onto a public;
road surface, the road shall be cleaned thoroughly at the end of each day.
Sediment shall be removed from the roads by shoveling or sweeping and
transported to a sediment control disposal area. Street washing shall be
allowed only after sediment is removed in this manner.
Stabilization of Denuded Areas and Soil Stockpiles: Permanent or temporary
soil stabilization must be applied to denuded areas within 7 days after final
grade is reached on any portion of the site. Temporary soil stabilization shall
be applied within 7 days to denuded areas which may not be at final grade
but will remain dormant (undisturbed) for longer than 14 days. Permanent
stabilization shall be applied to areas that are to be left dormant for more
than one year.
Soil stabilization refers to measures that protect soil from the erosive forces
of raindrop impact and flowing water. Applicable practices include vegetative
establishment, mulching and the early application of gravel base on areas to
be paved. Soil stabilization measures should be selected to be appropriate for
the time of year, site conditions and estimated duration of use.
Timing and Stabilization of Sediment Trapping Measures:
Sediment barriers and traps, perimeter dikes, sediment barriers and other
measures intended to trap sediment shall be constructed as a first step in
any land disturbing activity and shall be made functional before upslope land
disturbance takes place. Stabilization measures shall be applied to earthen
structures such as dams, dikes, and diversions immediately after installation.
Disposal of Temporary Measures: All temporary erosion and sediment control
measures shall be removed within 30 days after final site stabilization or after
the temporary measures are no longer needed, unless otherwise authorized by
the local program administrator.
Trapped sediment and the disturbed soil areas resulting from the disposition of
temporary measures shall be removed and replaced with suitably compacted
soils, or, where applicable, permanently stabilized to prevent further erosion and
sedimentation.
Maintenance: All erosion and sediment control structures and systems shall be
maintained, inspected, and repaired weekly and after each significant rainfall or
as needed to insure continued performance of their intended function. Any
damage to structural measures shall be repaired immediately.
Silt fence shall be inspected after every rainfall event and at least daily during
prolonged rainfall, as well as at the end of every working day, with any
necessary repairs made immediately. Accumulated sediment shall be removed
and disposed of as it becomes necessary, or when deposits have accumulated
to one-half of the above ground fence height. All undercutting or erosion shall
be repaired immediately. the contractor shall follow all manufacturers
recommendations for installation, maintenance, replacement, and repair.
damages caused by construction traffic or other activity must be repaired
before the end of each working day.
All seeded areas are to be checked to insure a good stand is maintained.

MINIMUM STANDARDS
MS -1 Permanent or temporary soil stabilization must be applied to denuded
areas within seven days after final grade is reached on any portion of the
site. Temporary soil stabilization shall be applied within seven days to
denuded areas that may not be at final grade but will remain dormant
(undisturbed) for longer than 15 days. Permanent stabilization shall be
applied to areas that are to be left dormant for more than one year. Soil
stabilization refers to measures which protect soil from the erosive forces of
raindrop impact and flowing water. Applicable practices include vegetative
establishment, mulching, and the early application of gravel base on areas to
be paved. Soil stabilization measures should be selected to be appropriate
for the time of year, site conditions and estimated duration of use.
MS -2 During construction of the project, soil stockpiles and borrow areas shall
be stabilized or protected with sediment trapping measures. The applicant is
responsible for the temporary protection and permanent stabilization of all
soil stockpiles on site as well as borrow areas and soil intentionally
transported from the project site.
MS -3 A permanent vegetative cover shall be established on denuded areas not
otherwise permanently stabilized. Permanent vegetation shall not be
considered established until a ground cover is achieved that, is uniform,
mature enough to survive and will inhibit erosion.
MS -4 Sediment basins and traps, perimeter dikes, sediment barriers and other
measures intended to trap sediment shall be constructed as a first step in
any land -disturbing activity and shall be made functional before upslope land
disturbance takes place.
NS -5 Stabilization measures shall be applied to earthen structures such as
dams, dikes, traps, basins and diversions immediately after installation.
MS -6 Surface runoff from disturbed areas that is comprised of flow from
drainage areas greater than or equal to three acres shall be controlled by a
sediment basin. The sediment basin shall be designed and constructed to
accommodate the anticipated sediment loading from the land disturbing
activity. The outfall device or system design shall take into account the
total drainage area flowing through the disturbed area to be served by the
basin.
MS -7 Cut and fill slopes shall be constructed in a manner that will minimize
erosion. Slopes that are found to be eroding excessively within one year of
permanent stabilization shall be provided with additional slope stabilizing
measures until the problem is corrected.
MS -8 Concentrated runoff shall not flow down cut or fill slopes unless
contained within an adequate temporary or permanent channel, flume, or
slope drain structure.
MS -9 Whenever water seeps from a slope face, adequate drainage or other
protection shall be provided.
MS -10 All storm sewer inlets that are made operable during construction shall
be protected so that sediment -laden water cannot enter the conveyance
system without first being filtered or otherwise treated to remove sediment.
MS -11 Before newly constructed stormwater conveyance channels are made
operational, adequate outlet protection and any required temporary or
permanent channel lining shall be installed in both the conveyance channel
and receiving channel.
MS -12 through 15 - Not applicable, no live watercourses.
MS -16 Underground utility lines shall be installed in accordance with the

that does not adversely affect flowing streams or off-site property.
d. Restabilization shall be accomplished in accordance with these regulations.
e. Applicable safety regulations shall be complied with.
MS -17 Where construction vehicle access routes intersect paved public roads,
provisions shall be made to minimize the transport of sediment by vehicular
tracking onto the paved surface. Where sediment is transported onto a
public road surface, the road shall be cleaned thoroughly every four hours.
Sediment shall be removed from the roads by shoveling or sweeping and
transported to a sediment control disposal area. Street washing shall be
allowed only after sediment is removed in this manner.
MS -18 All temporary erosion and sediment control measures shall be removed
within 30 days after final site stabilization or after the temporary measures
are no longer needed, unless otherwise authorized by the local program
