SHEETZ,INC.—NEW STORE
NEW AIRPORT ROAD,FLETCHER,NC 28732
PURPOSE: The purpose of this project is to construct a new Sheetz Store, 18 pump stations, and
corresponding parking lot. The project construction also includes: (1)Installation of
erosion control measures, (2) Grading, (3)Utility installation, (4)Building
construction, (5)Paving and(6)Re-stabilization of all disturbed areas.
SITE DATA: The 11.49 acre(9.63 acres disturbed) site is located on New Airport Road and
Airport Park Road in Fletcher,NC. The pre-developed site contains mostly
impervious area in the vicinity of the Sheetz store and mostly forested area in the new
parking lot area. The site has flat to moderate slopes. The site drains to the southeast to
an existing creek and west to an existing pond near New Airport Road.Properties
adjacent to the site are commercial to the northeast and industrial to the east,New
Airport Road to the west,Airport Park Road to the north,and Fanning Bridge Road to
the south.
SOILS: According to the web soil survey for Buncombe County,North Carolina the soil
classification of the site is Clifton sandy loam(CsC),Urban land(UhE), and
Hayesville loam(HyC).
EROSION& SEDIMENT CONTROL PRACTICES
1. Sediment Fence-6.62: To be installed around on downgrade side perimeter of disturbed area and
of stockpiles to intercept and detain sediment from sheet runoff of disturbed areas during
construction and prevent it leaving the site, not for concentrated flows.
2. Temporary Block& Gravel Inlet Protection-6.52: To be installed around all newly constructed
and existing drainage inlets to intercept and detain sediment from disturbed areas during
construction operations in order to prevent sediment from entering the storm pipe system.
3. Porous Baffles-6.65: Porous barriers installed inside temporary sediment basin to reduce velocity
of runoff and allow settling of sediment before leaving the site.
4. Concrete Washout Container: To be installed near the construction entrance/exit to receive wash
water from concrete trucks and concrete tools. The purpose of the container is to collect and retain
concrete solids and concrete wash water for proper disposal.
5. Temporary Sediment Basin-6.61: To installed in the southern corner of the site to retain sediment
on the construction site for most of the new parking lot, and prevent sedimentation in off-site
streams, lakes, and drainageways. It will allow large amounts of sediment to settle out of
construction runoff before it enters the storm pipe system.
6. Temporary/Permanent Seeding-6.10/6.11: To stabilize denuded areas during grading operations
and after land disturbance is completed.
7. Temporary Diversion-6.20: To be installed along east edge of disturbed area to direct runoff into
the sediment basin.

Step 1. Detennine the tailwater depth from channel characteristics below the
pipe outlet for the design capacity of the pipe. If the tailwater depth is less
than half the outlet pipe diameter,it is classified minimum tailwater condition.
If it is greater than half the pipe diameter,it is classified maximum condition.
Pipes that outlet onto wide flat areas with no defined channel are assumed
to have a minimum tailwater condition unless reliable flood stage elevations
show otherwise.

Step 2. Based on the tailwater conditions determined in step 1,enter Figure

Step 6. Fit the riprap apron to the site by making it level for the minimum
length,L.from Figure 8.06a or Figure 8.06b. Extend the apron farther
downstream and along channel banks until stability is assured. Keep the
apron as straight as possible and align it with the flow of the receiving stream.
Make any necessary alignment bends near the pipe outlet so that the entrance
into the receiving stream is straight.
Some locations may require lining of the entire channel cross section to assure
stability.
It may be necessary to increase the size of riprap where protection of the
channel side slopes is necessary(Appendix 8.05). Where overfills exist at
pipe outlets or flows are excessive,a plunge pool should be considered,see
page 8.06.8.
