EROSION AND SEDIMENT CONTROL PLAN
BOAR'S HEAD INN, INC.
CHARLOTTESVILLE, VIRGINIA
The rough grading and erosion control plan for the Boar's Head Inn,
Inc. in Charlottesville involves the addition of 74 Hotel Rooms and a parking
area. The proposed construction will be on a 2.5 acre parcel directly adjacent
to the Boar's Head Inn. The parcel at present is open pastureland with a heavy
vegetative cover of orchard and fescue grasses.
ROUGH GRADING PROGRAM
In this first phase of construction, the rough grading of the site shall
be established along with the necessary erosion and sedimentation control measures
to protect the disturbed areas. It is anticipated that the rough grading will commence
approximately 7 days after the rough grading permit has been issued and to be com-
pleted in 30 days. All required erosion and sedimentation, control measures for
this phase shall he implemented within 30 days following the conclusion of rough
grading.
The program for the rough grading shall be as follows:
The topsoil of all areas to be disturbed shall be first stripped, then stockpiled
and stabilized by temporary seeding.
The parking lot will be the first area to be rough graded. Since this will
involve the most cut, the resulting material shall be utilized as fill in subsequent
grading operations involving the entrance road. In addition, as the rough grading
commences, a perimeter dike with a gravel outlet and a temporary gravel construction
entrance shall be built. The parking and all other disturbed areas shall be seeded
with Italian rye grass and mulched within 30 days following the completion of the
grading. Straw bales will be placed as required to aid in the interception
of sediment and reduction of erosion until the temporary vegetative cover takes
hold. Permanent measures included during this phase are the drainage culverts
with riprap structures at their outlets to reduce the erosive forces of water.
Again, at the inlets and outlets of all drainage structures straw bales shall
be placed to further abate any erosion and sedimentation.
SOILS
The proposed area to be graded is underlain by a single soil type
designated the Cullen series. The Cullen is a well drained, deep residual soil
which has been weathered from the underlying granitic bedrock. Profile development
is strong with a dark brown A horizon approximately 8 inches thick and a B horizon
about 49 inches thick composed of red silty clay. The C horizon, a red friable
silt loam, extends to 110 inches or more. On the Boar's Head property much of
the A horizon (top soil) has been eroded off so that the B horizon in some areas
is exposed at the surface. NAtural slopes on the property range from a to 8
percent.
The Cullen is a moderately erodable soil with a K factor of .37 as
calculated by the Soil Conservation Service.
STORM WATER MANAGEMENT PROGRAM
No problems are anticipated from run-off of this 2.5 acre tract of land.
As As indicated on the attached drawings, storm drainage facilities are provided
and during construction will be utilized with appro?riate riprap rock and straw
bales to restrict sediment flowing from the property. -It should be further noted
that as permanent drainage, all storm water is directed to the lower`lake adjacent
to the Boar's Head Inn. The lake will act as a very efficient sediment basin for
this fine sediment, and no measurable amounts of suspended matter should escape
from the pond into downstream areas.

It should be noted that all appropriate erosion and sediment control
procedures will be enacted at the commencement of and during construction of the
entire project. Also as noted, there have been plans engineered to handle all
run-off in an appropriate fashion from the completed project.
