RECOMMENDED ON -SITE WASTEWATER SYSTEM ABANDONMENT PROCEDURES
1. DISCONNECT POWER AT THE SOURCE TO ALL SYSTEM ELECTRICAL CONTROLS. REMOVE
ALL PUMPS, CONTROLS, PANELS, AND OTHER APPURTENANCES AND DISPOSE OF AT AN
APPROVED OFF -SITE FACILITY.
2. HAVE AN APPROVED SEPTIC HAULER PUMP THE LIQUID, SLUDGE AND SCUM FROM ALL
EXISTING SYSTEM TANKAGE. CRUSH THE TANKS IN PLACE IF NOT LOCATED IN AN AREA OF
PROPOSED DEVELOPMENT. OTHERWISE REMOVE THE TANK AND DISPOSE OF AT AN
APPROVED OFF -SITE FACILITY. BACKFILL THE EXCAVATION WITH CLEAN NATIVE SOILS TO A
NATURAL GRADE AND ESTABLISH A VEGETATIVE COVER.
3. EXCAVATE AND REMOVE ALL COMPONENTS OF THE EXISTING SUBSURFACE DRAINFIELD AND
DISPOSE OF AT AN APPROVED OFF -SITE FACILITY.
4. REMOVE ANY TRENCH BIOMAT AND DISPOSE OF AT AN APPROVED OFF -SITE FACILITY.
5. SCARIFY NATIVE SOILS AND BACKFILL THE AREA TO A NATURAL GRADE AND ESTABLISH A
VEGETATIVE COVER.
6. COAT ALL SURFACE AREAS EXPOSED TO EFFLUENT WITH HYDRATED LIME AND ESTABLISH A
VEGETATIVE COVER.
ALTHOUGH NO SPECIFIC RULES GOVERN THE ABANDONMENT OF SUBSURFACE WASTEWATER
SYSTEMS, WE BELIEVE THESE RECOMMENDATIONS WILL ENSURE THAT SITES FORMERLY USED
FOR SUBSURFACE TREATMENT AND DISPOSAL ARE SAFE.

A. NARRATIVE AND SITE IDA T A
The project proposes to construct an 11,500 sf+ commercial building with various
outdoor entertainment amenities to include a miniature goff course. an elevated
ropes course and a zip -fine feature. Utilities; stormwater management, landscaping
and lighting improvements will also be provided to serve the development. The
project site is located along the west side of NC 12 at its intersection with Atlantic
Drive (SR 1247), in the village of Rodanthe, Kinnakeet Township, Dare County, North
Carolina.
The property is composed of a single parcel totaling 2.1 acres. The site's topography
gently slopes from east to west from NC 12 to the western shoreline with the Pamlico
Sound. Elevations range from just over 4 ft mil in the south east corner to less than
0.0 ft msi along the sound shoreline. The property was formerly developed with a
motel that has since been demolished- Besides remnant areas of gravel, asphalt and
utilities, the parcel is currently vacant. Surrounding land use is primarily commercial.
Site Soils are composed of.
CoB: Corolla Fine Sand: Described as being nearly level, moderately well
drained soils with rapid permeability. On -site soils investigation found high
permeability rates of 22.a inlhr and seasonal high water table conditions that
fluctuate from depths of 1.25 - 2.3 feet below the surface across the site.

ROLLED EROSION CONTROL MATTING SPECIFICATIONS:
All areas identifed on these plans as requiring an erosion control matting
shall be lined with a protective covering to minimize erosion and protect
seed until permanent vegetation is established.
Covering shall be composed of a bio or photo degradable material to
minimize long term environmental impacts.
Mulching with straw or other organic materials can be utilized only when it
will not impede the establishment of permanent vegetation. Mulches must
be properly anchored which may be difficult in some environments. An
example is straw mulch with jute netting stapled or pinned in place.
Pre -manufactured rolled erosion control products (RECP) are highly
recommended for this application. RECP's shall be installed according to
manufacturer specifications for channel linings. An example is a woven

accordance with the approved sedimentation control pion and construction schedule.
2. Remove good topsoil from areas to be graded and filled, and preserve it for use
in finishing the grading of all critical areas.
3. Scarify areas to be topsoiled to a minimum depth of 2 inches before placing
topsoil.
4. Clear & grub areas to be filled to remove trees, vegetation, roots, or other
objectionable material that would affect the planned stability of fill.
5. Ensure that fill material is free of brush, rubbish, rocks, logs, stumps, building
debris, and other materials inappropriate for constructing stable fills.
6. Place all fill in layers not to exceed 9 inches in thickness, and compact the
layers as required to reduce erosion, slippage, settlement, or other related problems.
7. Do not incorporate frozen material or soft, mucky, or highly compressible
materials into fill slopes.
8. Da not place fill on a frozen foundation, due to possible subsidence and slippage.
9. Keep diversions and other water conveyance measures free of sediment during all
phases of development.
10. Handle seeps or springs encountered during construction in accordance with
approved methods
11. Following completion of any phose of grading, provide a groundcover (temporary

PERMANENT SEEDING
The purpose of permanent seeding is to reduce erosion and decrease
sediment yield from disturbed areas, and to permanently stabilize such areas
in a manner that is economical, adapts to site conditions, and allows
selection of the most appropriate plant materials. These areas must be
seeded or planted within 15 working days or 90 calendar days after final
grade is reached, unless temporary stabilization is applied -

SODDING
The purpose of permanent seeding is to prevent erosion and damage from
sediment and runoff by stabilizing the soil surface with permanent vegetation
for the purpose of --
-the
provision of immediate vegetative cover in critical areas
-to stabilize disturbed areas with a suitable plant material that cannot be
established by seed_
-to stabilize drainage ways & channels and other areas of concentrated flow
where flow velocities will not exceed that specified gross lining.
SODDING SPECIFICATIONS
Sod Quality
-Sod should be machine cut at a uniform depth of 1/2-2 inches
-Sod should not have been cut in excessively wet or dry weather.
-Sections of sod should be standard size as determined by the supplier,
uniform, and untorn.
-Sections of sad should be strong enough to support their own weight and
retain their size and shape when lifted by one end.
-Harvest, delivery, and installation of sod should take place within a period
of 36 hours.
Soil Amendments -
Apply lime and fertilizer according to soil tests or apply 75 lb/1,000 sf of
pulverized agricultural limestone and 1,000 !b/ocre 10-10-10 fertilizer in the
fall, or 5-10--10 in spring -
FOR CENTIPEDE GRASS ONLY -- Apply J ib or nitrogen per 1I,000 s,f.
Prior to taying sod, clear the soil surface of trash, debris, roots, branches,
stones, and clods larger than 2 inches in diameter. Fill or level low spots in
order to avoid standing water. Rake or harrow the site to achieve a smooth
and level final grade. Complete soil preparation by rolling or
cultipacking to firm soil.
Sod Installation-
1. Moistening the sod after it is unrolled helps maintain viability, Store in
shade during installation.
2. Rake the soil surface to break the crust just before laying sod. During the
summer, lightly irrigate the soil, immediately before laying sod to cool the
soil and reduce root burning & dieback.
3. Do not sod on grove, frozen soils, or soils that have been treated recently
with steriiants or herbicides.
4. Lay the first row of sod in a straight line with subsequent rows placed
parallel to and butting tightly against each other, Stagger strips in a
brick -like pattern. Be sure that the sod is not stretched or overlapped and
that all joints are butted tightly to prevent voids. Use a knife or sharp spade
to trim and fit irregular shaped areas.
5. Install strips of sod with their longest dimension, perpindicuior to the slope.
On slopes of 3:1 or greater, or wherever erosion may be a problem, secure
sod with pegs or staples.
6. As sodding of clearly defined areas is completed, roll sod to provide good
contact between roots and soil.
7. After rolling, irrigate until the soil is wet 4 inches below the sod,
S. Keep sodded areas moist to a depth of 4 inches until the grass takes
root. This can be determined by tugging on the sod.
9. Mowing should not be attempted until the sod is firmly rooted, usually
2-3 weeks.
Sodded Waterways
1. Prepare soil as described above.
2. Lay sod strips perpindicular to the direction of flow, with the lateral joints
staggered in a brick -like pattern. Butt edges tightly together.
Maintenance -
After the first week, water as necessary to maintain adequate moisture in
the root zone & prevent dormancy of the sod.
Do not remove more than one-third of the shoot in any one mowing. Grass
height should be maintained between 2-3 inches unless otherwise specified.
After first growing season, established sod requires fertilization, and may also
require lime. Follow soil test recommendations.
