dated July 15, 1996.
2 Topographic information taken from topographic survey
in 1983. No reported major topographic ch:nges are
reported in the interviening years.
3 These plans are for sedimentaion and erosicn control
and stormwater permits only, other permits and
certificates by others.

directed into swales 100' minimum from swcle outlet
5 Wooden sheet pile bulkhead to be installed as required
to prevent disruption of 404 wetlands.

SEDIMENTATION + EROSION CONTROL
FOR SITE DEVELOPMENT CONSTRUCTION
PURPOSE
To reduce on -site erosion and off -site sedimentation caused by
the land disturbing activity during site development.
PROJECT DESCRIPTION:
The project consists of constructing the Pecan Grove Marina
to include buildings. parking areas, dockage. and other
appertnances.
SITE DESCRIPTION:
The site is a parcel of land located in Township No. 5, Pamlico
County along SR 1305 and Shop Gut. The area to be disturbed
was formerly used as a campground and a restaurant located on the
southeastern corner of the property.
SOILS,
Basically the area has very shallow layer of sandy topsoil, fol-
lowed by either sand or fine sand.
CONSTRUCTION SCHEDULE:
No land disturbing work shall begin on the site until the Sedi-
mentation + Erosion Control plan is approved.
A pre -construction meeting with one C1) week notification time
shall be held prior to any land disturbing activity.
Install the temporary gravel construction entrance from SR 1308
to provide access for construction equipment and materials.
Egress and Ingress of other locations for other than personal
vehicles will require written permission and additional temporary
gravel construction entrances.
Install sediment fence at the locations indicated on the drawings;
i.e. some areas will be along the clearing limits.
Install stone checks, riprap outlet structures, stabilize with
temporary seedings. etc. as areas are graded; permanent seeding
can be performed in lieu of temporary seeding in areas not to be
re -disturbed.
Stabilize parking areas, drives, ramps. etc. with stone base
course as soon as practical.
All temporary erosion control measures shall be properly in-
stalled within thirty C30) days of the completion of the land
disturbing activity in the area.
Afterthe upstream areas have been properly stabilized, seed the
sediment basin wit' p manrnt
MAINTENANCE SCHEDULE:
Inspect the sediment fence, and stone checks on a weekly basis.
Repair or replace the sediment fence when damaged or when failing
to properly contain sediment.
Remove sediment from the stone checks when less than one (1) foot
of freeboard remains; remove, clean or replace stone when it
becomes impervious.
OOF DRAINS TO BE COLLECTED Repair and reseed all areas of either temporary or permanent
ND DRAINED TO OUTLET SWALE seeding that are eroding.
UTH OF BUILDING AT LEAST PROJECT CLOSE OUT SEQUENCE:
5 'FROM SWALE OUTLET. INTO
SA WATERS No erosion control devices shall be removed until the land dis-
turbing activities. with the exception of landscaping, have been
completed and the areas stabilized.
Once the permanent seeding has established itself and the parking
areas are stabilized the perimeter silt fence can be removed.
PS After the permanent seeding has stabilized the invert and slopes
cf the drainage swales, the stone checks may be removed and temp-
orary sediment basins modified to rip rap lined channels.
I ®4.40'
After the completion of construction the entire area shall be
inspected monthly by the owners representative for a period of
one (1) year. The owners' representative will keep a written log
of needed repairs and a record of the contractor making the
repairs including the date the repairs were completed.
