HomeMy WebLinkAboutWPO201600036 Plan - E&S WPO VSMP 2016-06-10Erosion and Sediment Control Narrative For:
Carver Bridge
Parcel: 05900-00-00-037C6
Pallas Hill Lane (no assigned address)
Charlottesville, Virginia
Project Description: The proposed work includes the construction of a new
bridge for access to Brook Rd. The total area of the parcel is 4.62 acres, of
which 0.27 acres will be impervious surface. The total on-site disturbed area
is approximately 0.38 acres, most of which will be created by providing an
access road to the bridge site. The Work is anticipated to begin upon
approval of the erosion and sediment control plan.
Work will include clearing, grubbing and grading, as shown on the plans.
Erosion control measures shown will protect the stream below from receiving
silt -laden runoff.
Existing Site Conditions: The site is currently undeveloped with the exception of
an existing driveway. The site generally slopes from northwest to southeast at
varying slopes. No critical slopes will be disturbed.
The pre and post drainage patterns will be the same. There are no existing
drainage or erosion problems directly associated with this site.
Runoff from the site discharges into Ivy Creek, which borders the property to
the southeast. The proposed erosion and sediment control measures will
eliminate potential for erosive damage to private properties. Since the site is
not openly exposed to winds, and the limited amount of site work, dust
control should not be an issue.
Adjacent Property: The property is bounded on all sides by large,
single-family properties with open and wooded terrain.
Off-site Areas: No off-site areas will be disturbed.
Soils: 4D - Ashe loam
4E - Ashe loam
19B - Cullen loam
36C - Hayesville loam
Critical Erosion Areas: There are no critical erosion areas associated with this
project.
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 during construction by the
County Erosion Control Official, as needed.
Structural Practices:
Safety Fence: (SAF) 3.01 A protective barrier installed to prevent access to
an erosion control measure. (To be installed along limits of disturbance within the stre(atrt buffer)
Construction Entrance: (CE) 3.02 A stabilized stone pad with a filter fabric
underliner located at points of vehicular ingress and egress on a construction
site. (To be installed at entrance to remove soil.front tit -es prior to travel on public roads)
Silt Fence: (SF) 3.05 Silt fence (wire -supported) shall be constructed along
the lower limit of graded areas. (To be installed as shown on the plan at the base of the slopes
created by the proposed excavation. )
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. Given the limited
scope of work and schedule, no temporary seeding is necessary.)
Mulching (MU) 3.35 Application of plant residues to disturbed surfaces to
prevent erosion and reduce overland flow. Apply to all seeded areas. (Tobe
installed with Permanent Seeding)
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 30 days, will be stabilized
by establishing a good stand of grass.
Lime 3.31:
Unless
it is known that the
site will remain 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 soil.
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 % to i 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 traps are
to be cleared at 50% storage capacity level. 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 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 which protect soil from the erosive forces of raindrop
imipact 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.
MS -5 Stabilization measures shall be applied to earthen structures
suich as dams, dikes, traps, basins and diversions immediately after
installation.
MS -6 Surface runoff from disturbed areas that is comprised of flow
frcom 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
mlinimize erosion. Slopes that are found to be eroding excessively
wiithin 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
of:her protection shall be provided.
MS -1!0 All storm sewer inlets that are made operable during
cconstruction shall be protected so that sediment -laden water
cannot enter the conveyance system without first being filtered or
oltherwise treated to remove sediment.
MS -1 1 Before newly constructed stormwater conveyance channels are
made operational, adequate outlet protection and any required
tEemporary or permanent channel lining shall be installed in both
the conveyance channel and receiving channel.
MS -12 through 15 - Not applicable, no live watercourses.

rcegulations.
e,. Applicable safety regulations shall be complied with.
MS -1 7 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
bie cleaned thoroughly every four hours. Sediment shall be
rcemoved from the roads by shoveling or sweeping and transported
t(o a sediment control disposal area. Street washing shall be
aillowed only after sediment is removed in this manner.
MS -1 8 All temporary erosion and sediment control measures shall be
rcemoved within 30 days after final site stabilization or after the
tEemporary measures are no longer needed, unless otherwise
aiuthorized by the local program administrator. Trapped sediment
