PLANNED EROSION AND SEDIMENT CONTROL PRACTICES -
CE i. T PtORe SY GAVEL CONSTRUCTION ENTRANCE
.06
Shall be installed at the entrances to the project
from an existing roadway. Drainage should be away from
the road and erosion will be controlled with downstream
proctices. During wet weather it may be necessary to wash
truck tires at these locations.
2. LAND GRADING
Practice 6.02
Grading should be limited to areas as shown on the
Plans. Cut and fill slopes shall be 3.1 or flatter except
where specifically indicated. Care shall be taken during
land rading activities not to damage existing trees that
are identified as 'to be preserved'.
SF 3. SEDIMENT FENCE
Practice 6.62
Sediment fencing should be Installed as shown on the
Plan, to delineate and protect wetlands and specified areas,
and around any temporary stockpile areas as necessary to
prevent any graded interior areas from eroding onto adjacent
lands or roadway, or Into Inlets, or as directed by Engineer
or NCDENR/LOS personnel.
GC 4, GRASS-LINED
aSS-ctice 6 30 CHANNELS
All overflow swales to be graded to design configuration,
lined with centipede sod, to collect and convey site water
as shown on Plan. After final pproject stabilization, swales to
be re -faded, cleaned of slltaikm and lined with centipede sod
to esta ash original design contours for stormwater conveyance.
�P 5. OUTLET STABIUZA71ON
Practice 6.41
Riprop aprons will be located at the downstream and of
all discharge pipes to prevent scour.
6. CONSTRUCTION ROAD STABIUZA77ON
Practice 6.80
Upon reaching final grade and after utilities have been
Installed, roadway%parking areas are to be stabilized by placing
sub -base course of approved 4' marl stone or 6' ABC, as shown
In the typical street cross-section detail on the Plan, to
reduce erosion and dust during the remainder of building
construction.
$B 7. SEDIMENT BASIN
Practice 6.61
The Sediment Ba in is to be constructed first (see
Construction Schedule) and is the primary Practice to
prevent sediment from leaving the site. Detailed design and
spillway configurations are specified in the detail sheet.
SK a SKIMMER
Practice 6.64
A sedimentation basin dewatering control device that withdraws
water from the basins water surface, thus removing the highest quality
water for delivery to the uncontrolled environment.
CONSTRUCTION SCHEDULE -
1. Obtain approval of Plan and any necessary permits, and hold
a pre -construction conference prior to commencing any work.
2 Flag work limfts and stakeout parking lot and storm drainage
structures for preliminary grading.
J. Install Gravel Construction Entrances.
4- Install sediment basin and silt fencing as shown on
plan prior to clearing and grubbing site.
5. Construct gross lined channels,
and any other sediment control practices shown, prior to
rough grading roadways, site and stockpiling topsoil as necessary.
6. Install utilities In roadway/parking lot, establish final grades
and stabilize road/parking lot with stone base course.
