Note:
The flood ay and floodplain are
plotted from the Community Map
37189 C0184 dated January 17, 1997,
The slope stabilization methods as
detailed on Sheet 2 of 2 is adequate
to support any occurrence of flood
waters along the new slope embankment.
BLUEBIRD LANE EXTENSION
Existiag Driveway Has Been
Used at This Location for
the length of time the Property
has been in Ownership by Radford
Ouarries and constructed prior to
there ownership. Driveway does
not need -o NCDOT Permit and
should be grandfathered EE=
Embankment:
Locate sediment trap as near the sediment source as topography allows.
Divert runoff from all undisturr)ed areas away from sediment trap.
Clear, grub, and strip all vegetation and root mat from area of embankment
Use stable mineral soil free ,,,! roots, rocks, debris, and other objectionable material.
Place fill in 9 inch lifts, max:,Iium, Machine compact each lift. Construct
side slopes 2:1 or flatter (3: ', recommended for backslope to improve
stability of stone spillway).
Overfill embankment to 6 incl eS above design elevation to allow for settlement.
Outlet Section:
Excavate trapezoidal stone oa;flet section from compacted embankment.
Allow foc thickness of stone gide slopes (21" Minimum),
install filter fabric under nprr;p. Extend fabric up the slope to top of embankment.
Place specified stone to lines and grades shown on plans, working small stones
into the voids to achieve a -",�
,,_'nse mass. Spillway crest must be level with
minimum inside dimension sprwcified in plan. Measure spillway depth from
the highest stones in the spirway to the design elevation of dam. Minimum
depth of 1.5 feet.
Keep sides of the stone outirt', section at least 21 inches thick through the
level section and the downstr-4,0m face of dam,
Extend outlet apron below tc,,, of dam on level grade until stable conditions
are reached (5 foot minimurr/,. Edges and end of the stone apron section
must be flush with surroundirg ground. No overfall should exist.
Cover inside face of stone ou-fet section with a 1 foot thick layer of 1/2 to
3/4 inch aggregate (NCDOT #57 or #5 washed stone).
Vegetate the embankment in accordance with the vegetation plan.
Set a stake at one-half the design depth. This will be the cleanout level.

1. Silt fence shall be constructed before wzslope land disturbance begins.
2. All silt fence shall be placed as close lz the contour as possible so
that water will not concentrate at low points in the fence and so that
small swoles or depressions which may carry small concentrated flows to
the silt fence are dissipated along its leiigth.
