EROSION AND SEDIMENT CONTROL NARRATIVE
Charlottesville Self Storage
Erosion and Sediment Control Plan
The County of Albemarle, Virginia
PROJECT DESCRIPTION
The scope of this E &S narrative and plan is for the purpose of developing soil in preparation for
the construction of additional storage buildings on site.
A total of approximately 4.4 acres will be disturbed during construction.
EXISTING SITE CONDITIONS
The topographic and built improvements existing on the subject property are depicted on the
accompanying E &S plan, utility plan & profiles, and the general notes sheet.
ADJACENT AREAS
The northeastern edge of the property is bound by Moore's Creek. The northwestern edge is
adjacent to Avon Street Extended. The southwestern edge is bound by a driveway adjacent to
the City of Charlottesville's bus yard. The remaining southeastern edge is bordered by
undeveloped land adjacent to Moore's Creek. The entire watershed for the project is tributary to
Moore's Creek.
OFF -SITE AREAS
All land disturbing activities shall occur on -site and within the limits of project shown on the
plans. At this point, no off -site borrow, waste or grading activity will occur.
SOILS
This site is located in a geologic area referred to as the Piedmont Physiographic Province. The
soils in this geologic area are weathered from the underlying metamorphic bedrock. The
naturally occurring soils at this site were found to be moderately to highly plastic silts weathered
from the Catoctin formation which consists of basic lava flows, schist, and gneiss composed of
chlorite, plagioclase, amphiobole, and epidote. The soils observed here appear to be
weathered from metamorphosed sedimentary soils such as phyllite and schist.
The map units on the detailed soil map depicted on the Erosion and Sediment Control Plan,
represent the soils in the survey area. The map unit descriptions, along with the soil maps, can
be used to determine the suitability and potential of a soil for specific uses, and, precautionary
erosion and sedimentation control measures which must be adhered to. They also can be used
to plan for the management needed for those uses. The profile of the soil classifications
follows:
Catoctin, Silt Loam (12D): This moderately deep, moderately steep (15 -25 %) soil is well
drained on side slopes. Usually, the surface layer is dark brown and dark yellowish brown silt
loam about five (5) inches thick. The subsoil is strong brown, extremely channery silt loam
containing pockets of reddish brown silty clay loam and is about thirteen (13) inches thick. The
substratum below a depth of eighteen (18) inches is yellowish brown, extremely channery silt
loam. Permeability is moderately rapid, and available water capacity is very low. Surface runoff
is rapid. The hazard of erosion is severe. The subsoil has low shrink -swell potential. Depth to
bedrock is twenty (20) to forty (40) inches.
Udorthents, loamy (88): This map unit is made up of areas that have been used for cutting or
filling during grading for road construction, housing developments, recreational areas, quarries,
and other similar uses. The areas are generally irregular in shape, and conform to property
boundaries. Slopes mainly range from 2 to 25 %. Permeability ranges from rapid to slow.
Water capacity is generally moderate. Surface runoff and erosion range from moderate to
rapid. Onsite investigations are required to determine the use and management of these soils
CRITICAL AREAS
There are several critical areas on the site. These are slopes created during previous phases of
construction on the site and include all areas of proposed buildings.
EROSION AND SEDIMENT CONTROL MEASURES
The contractor shall provide, construct and maintain erosion and sediment control measures on
the site, in accordance with the Virginia Department of Transportation and the County of
Albemarle erosion and sediment control measures (refer to the Erosion and Sediment Control
Plan sheet). All vegetative and structural erosion and sediment control practices shall be
constructed and maintained according to minimum standards and specifications of the Virginia
Erosion and Sediment Control Handbook.
Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7)
days after final grade is reached on any portion of the site. Temporary soil stabilization shall be
applied within seven (7) days to denuded areas that may not be at final grade but will remain
dormant (undisturbed) for longer than 30 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 stone. Soil stabilization measures should be
selected to be appropriate for the time of the year, site conditions, and estimated duration of
use.
Temporary sediment filters and traps, perimeter dikes, sediment barriers and other measures
intended to retain sediment shall be constructed as a first step in any land- disturbing activity and
be made functional before up slope land disturbance takes place.
Stabilization measures shall be applied to earthen structures such as dams, dikes and
diversions immediately after installation.
The following structural practices will be implemented according to the requirements set forth by
the Virginia Erosion and Sediment Control.
a). Paved Wash Rack Construction Entrance (3.02)
A seventy (70) foot paved section shall be installed at the point of vehicular ingress and egress
on the construction site. This paved area shall be used for washing sediment from vehicles
exiting the site. 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. This provision shall apply to
individual subdivision lots as well as larger land disturbing activities.
Specific Application: A construction entrance shall be placed adjacent to Redfields Road on the
southern border of the property
b). Construction Road Stabilization (3.03)
Temporary stabilization with stone of access roads, subdivision streets, parking areas and other
traffic areas immediately after grading to reduce erosion caused by vehicles during wet weather,
and to prevent having to regrade permanent roadbeds between initial grading and final
stabilization.
Specific Application: Construction road stabilization shall be applied in areas which require
stabilization after preliminary and fine grading. These areas include but may not be limited to
the travelways.
c). Silt Fence (3.05)
A temporary sediment barrier consisting of synthetic filter fabric stretched across and attached
to supporting posts and entrenched. Used to prevent sediment from leaving the site. To
decrease the velocity of sheet flows.
Specific Application: Silt fence will be used at the foot of the cut / fill slopes.
d). Inlet Protection (3.07)
A temporary sediment filter around a storm inlet or curb inlet, in order to prevent sediment from
entering storm drainage systems prior to permanent stabilization of the disturbed area.
Specific Application: Inlet protection will be used around all storm drainage inlets and curb
inlets.
Temporary Diversion Dike (3.09)
A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area.
Used to divert sediment -laden runoff from a disturbed area to a stabilized outlet.
Specific Application: Diversion Dikes will be used to divert runoff away from the disturbed areas
of construction to the sediment traps.
f). Temporary Sediment Trap (3.13)
A temporary ponding area formed by constructing an earthen embankment with a stone outlet.
It is used to detain sediment -laden runoff from drainage areas less than three acres for enough
time to allow most of the sediment solids to settle out. It can be constructed only where there is
sufficient space and appropriate topography. Maximum effective life is 18 months.
Specific Application: Sediment traps will be used to detain runoff on the site at the foot of the fill
and cut slopes.
2L Temporary Slope Drains (3.15)
A flexible tubing or conduit extending from the top to the bottom of a cut or fill slope. The drains
will temporarily conduct concentrated runoff safely down the face of a cut or fill slope without
causing erosion on or below the slope.
Speck Application: The drains shall be used to divert "clean" water from the high side of
slopes affected by the construction of the proposed buidlings. Outlet protection shall be applied
at the bottom of the drain.
h). Outlet Protection (3.18)
Structurally lined aprons or other acceptable energy dissipating devices placed
at the outlets of pipes or paved channel sections. To prevent scour at
stormwater outlets and minimize downstream erosion.
Specific Application: This form of protection shall be performed on all stormwater
outlets by using nprap.
i). Surface Roughening (3.29)
This erosion and sedimentation control measure involves creating horizontal
depressions on slopes or leaving slopes in a roughened condition by not
fine- grading them. This is done to aid in the establishment of vegetative cover or
seed, to reduce runoff velocity and increase infiltration, and to reduce erosion
and provide for sediment trapping.
Specific Application: This form of protection shall be performed on all slopes 3:1
or greater as shown on the accompanying E &S Plan. Slopes less steep than 3:1
should have the soil lightly roughened and loose to a depth of 24" prior to
seeding.
D. Temporary Seeding (3.31)
The establishment of a temporary vegetative cover on disturbed areas by
seeding with appropriate rapidly growing annual plants. This protects slopes
exposed during construction until permanent vegetative cover can be
established. Temporary seeding will apply to all areas on the site that will not be
brought to final grade for periods of thirty (30) days to one year. Selection of the
appropriate seed mixture depends upon the time of year it is to be applied (See
schedule on E &S details sheet.)
Specific Application: Temporary seeding shall be applied to all denuded areas
prior to permanent stabilization in the form of either hardscape or permanent
seeding. Temporary seeding shall be used on all fill slopes and diversions.
k). Permanent Seeding (3.32)
Establishment of perennial vegetative cover by planting seed on rough- graded
areas that will not be brought to final grade for a year or more or where
permanent, long -lived vegetative cover is needed on fine- graded areas.
Specific Application: Permanent seeding will be applied to all portions of
distulrbed area.
I) Mulching (3.35)
it will prevent erosion b
The application of plant residues to the so surface p e y
protecting the soil surface from raindrop impact and reducing the velocity of
overland flow. Mulch will foster the growth of vegetation by increasing available
moisture and providing insulation against extreme heat and cold.
Specific Application: Bark chips or shredded bark applied in conjunction with
ornamentals for landscaping purposes.
m). Soil stabilization Blankets & Matting (3.36)
Stabilizing disturbed areas of a steep slope, channel, or a shoreline by applying
protective covering on a prepared area. The matting will protect the young
vegetation and promote its establishment while increasing the permissible
velocity of turf grass stands.
Specific Application: Where the proposed detention pipe outlets.
1. Dust Control (3.39)
Reducing surface air movement of dust during land disturbances, demolition or
construction activities in areas subject to dust problems in order to prevent soil
loss and reduce the presence of potentially harmful airborne substance.
Specific Application: Dust control shall be applied as necessary if time requires.
o). Diversion (3.12)
A channel constructed across a slope with a supporting earthen ridge on the
lower side. Used to reduce the slope length and to intercept and divert
stormwater runoff to stabilized outlets at non - erosive velocities.
Specific Application: Diversions will be used to direct "clean" water from the
existing storm pipes off -site.
p) Fill Diversion (see 3.09)
A temporary ridge of compacted soil constructed at the top or base of a sloping
disturbed area. Used to divert sediment -laden runoff from a disturbed area to a
stabillized outlet.
Specific Application: Diversion Dikes will be used to divert runoff away from the
disturbed areas of construction /.
PERMANENT STABILIZATION
All areas disturbed by construction will be stabilized with permanent seeding
immediately following finish grading. All seeds will be approved by the "Virginia
Crop Improvement Association," Blacksburg Virginia. Seeding will be done with
the following:
Two (2) parts Kentucky Bluegrass (Poa pratensis), by weight; minimum 98 %
purity and 90% germination; maximum 1 % weed seed.
Three (3) parts perennial Ryegrass (Labium perrene) by weight; minimum 85 %
purity and 90% germination; maximum 1 % weed seed.
Fifteen (15) parts Falcon Fescue; minimum 98 % purity and 90% germination;
maximum 1 % weed seed.
Permanently seeded areas shall be protected during establishment.
Mulch shall consist of oat or wheat straw, free from weeds, foreign matter
detrimental to plant life, and dry. Hay or chopped cornstalks will not be
permitted.
Mulch and /or lime shall be applied at a rate of two (2) tons per acre.
Specifications for fertilizer are FS 0 -F -241 C, Type 1, solid form; Grade A or B;

With at least fifty (50) percent of the nitrogen from a non -water soluble organic
source.
The following measures shall be incorporated during fertilization:
Apply fertilizer at a rate of 1000 lbs. /acre.
Apply after smooth raking of topsoil.
Do not apply fertilizer at same time or with same machine as will be used to
apply seed.
Till fertilizer into upper two (2) inches of topsoil.
Lightly water dry topsoil to depth of six (6) inches at least forty -eight (48) hours
prior to seeding to obtain a loose friable seed bed and to aid in the dissipation of
fertilizer.
The following rates and practices will be adhered to for all seeding that occurs
on -site:
Apply seed a rate of 6- lbs. 11000 sq. ft. evenly at right angles with a spreader or
seeding machine. Rake, in lightly, covering seed to depth of 118 inch.
Do not seed area in excess of that which can be mulched on same day.
Do not sow immediately following rasp, when ground is too dry, or during windy
periods.
Roll seeded area with roller not exceeding 112 lbs.
immediately following seeding and compacting apply mulch to a thickness of one
(1) inch. Maintain clear of shrubs and trees.
Apply water with a fine spray immediately after each area has been mulched.
Saturate to six (6) inches of soil.
MAINTENANCE
All erosion and sediment control measures must be maintained and repaired
immediately to insure continued performance of their intended functions as
stated in the Virginia Erosion & Sediment Control Handbook, Third Edition 1992.
In general, all erosion and sediment control measures will be checked weekly
and after each runoff - producing rainfall event. All seeded and sodded areas will
be checked regularly to ensure that a good stand is maintained. Areas will be
fertilized, reseeded and Iresodded as needed.
DISPOSITION OF TEMPORARY MEASURES
All temporary erosion and sediment control measures, including the temporary
sediment basins, shall be removed within 30 days after final site stabilization is
achieved or after the temporary measures are no longer needed, unless
otherwise authorized by the local program administrator. Trapped sediment and
other disturbed soil areas resulting from the disposition of temporary measures
shall be permanently stabilized to prevent further erosion and sedimentation.
STORMWATER MANAGEMENT
Where applicable, silt fence and seeding will be capable of separating
suspended solids from the runoff before it enters the existing natural channels.
The runoff from the drains will increase the velocity of the runoff from outflow
devices, but will dissipated by utilizing outlet protection in the form of riprap.
Erosion control stone placed at the end of these outfalls will protect the channels
and decrease the flow velocity. The bio- retention basin will treat both the onsite
as well as contributing stormwater passing through the site for quality. Since the
project is adjacent to the 100 yr floodplain, a waiver will be applied for to treat the
stormwater for quality only and not for quantity.
