EROSION AND SEDIMENTATION
CONTROL NOTES:
J. CondructJon Sequence
a. Notify owner, Engineer and Land Quallly Section prior to beginning
construction.
b.Clearing or grading shall begin at low points, points of outfa!l
release or at other locations where sediment measures are shown
on the plan, and the sediment control devices (sediment traps, silt
fences, diversion stormwater treatment areas, etc.) shall be
Installed before or simultaneously with the disturbance of any
area draining to the device.
c. Limits of disturbance will be according to the plan as shown. Silt
fence sholl be installed Immedlate/y after disturbance Ilt fence
shall be maintained until the disturbed area is stabilized completely.
Silt fences are shown based on topographic Information /n the
locations expected to be needed to trap sediment prior to entering
down slope areas. Actual locations of Installation shall be adjusted
to the actual physical on site topogropohy.That Is, where silt fence
Is not shown on the plan but the actual topography reflects a
downward slope�sllt fence shall be Installed Where the actual
topography reflects an upward slope silt fence is not required.
d. Construct infiltration basin. See Infiltration basin detall for more
Information.
e. Strip and stockpile topsol/ for later use. Rough grade site.
f.Install catch basins, storm draln pipes and drainage swales.Immediately
construct sediment traps and rock check dams where shown.Wlthin l5
days, temporary seed swages If not /n final condition or permanent
seed and Install Swale l)ner,lf In fowl condition.
g. Within /5 days upon completion of grading, install temporary or
permanent seeding and mulching.
h Fine grade drives and parking area, place CABC over compacted subgrade
I. Establish groundcover on exposed slopes within /5 calendar days following
completion of any phase of grading.
J. Contractor must conduct and pass a proof roll test, on the
subrade proor to Installing stone. The proof roll test shall
be conducted In the presence of the Engineer.
k. Seed, fertilize and mulch all disturbed areas within 15 days of
conpleting any phase of the grading work.App/y temporary seeding If
area Is o be disturbed again and permanent If areas have been final
graded and accepted by the engineer and owner.
2. Seeding SpeciflooNaxs:

all erosion control measures and
shall amend measures as required to prevent accelerated erosion from taking
place on this site, until site Is restab1//zed
and accepted by the
engineer and owner.
4. Upon restablllzation of all disturbed areas and swales, contrractor shall remove
all temporary erosion control facilities and

CROSS SECTION A -A DETAIL
Not to Scale
NOTES
1. Notify Engineer 48 hours prior to beginning construction.
2.The infiltration basin requires Inspection during construction and upon completion
requires certification of construction to the North Carolina Division of Water
Quality by a North Carolina Professional Engineer.
3.The Infiltration basin Is not to be used as a sediment trap. Stormwater shall
be diverted away from the Infiltration basin until contributing watersheds are
completely stabilized
4.Excavate and grade the side slopes of the basin to elevation 4130
5. Immediate upon excavation, silt fences shall be placed at the bottom of the basin
sides and remain In place until the side slopes are stabilized.
6.Contractor shall measure basin to ensure correct size.
7.Install Inlet pipes and flared end sections.
8.Install filter cloth barrier.
9. Place 6' clean sand over filter cloth barrier at basin bottom to elevation 3820.
IO.Sod side slopes.
It. Install r1p rap level spreaders.
12.Place slit fence at top of basin to prevent erosion.

area stabilized with crushed stone which drains Into an
approved sediment trap or sediment basin. All sediment
shall be prevented from entering any storm drain,dltcla
or watercourse ttrough use of sandbags, gravel, boards
or other approved methods.
6. Maintenance — The entrance shall be maintained In a
condition which will prevent trocklnq or flowing of
sediment onto public right of way. This may require
periodic top dressing with additional stone as conditions
demand and repair and/or cleanoutof any measures used to
trap sediment .All sediment .spilled ,dropped,wasted or
tracked onto public rlghlt of way must be removed
Immediately.
