PROPOSED GIDEON CREEK MARINA JAN 2 5 2008
4146 ORCHARD CREEK ROAD, NCSR 1317
PAMLICO COUNTY, NORTH CAROLINA DWQ- l/d ®O
Project Description
The proposed Gideon Creek Marina project encompasses the development of a 30 slip marina on
a 5.67 acre parcel of land located off of Gideon Creek in the Pamlico Community in Pamlico
County, North Carolina. The subject property is currently partially developed as a commercial
use marina and fish house. The subject property is located at the intersection of Pamlico Road,
NCSR 1320 and Orchard Creek Road, NCSR 1317. The subject property is bordered along its
eastern side by Gideon Creek. A site location map and a 7.5 minute USGS Quadrangle Map of
the project area is included on the project plans.
Existing development on the eastern side of the subject property consists of wooden piers, wood
shelters and remains of several other commercial use buildings, concrete slabs, a dilapidated
residential dwelling and gravel and dirt parking and traffic circulation areas. The wood pier
system is in a dilapidated condition and will accommodate approximately 12 - 18 boats
depending on the length of the vessels. The western portion of the subject property was
previously developed for residential uses. An existing block framed residential dwelling is
located on this portion of the site. Additionally, a wood -framed shelter and commercial fishing
gear is presently being stored on this area of the property. A total of 2.37 acres of the subject
property are located on the western side of Orchard Creek Road as presented on the project plans.
It is proposed that the existing commercial marina be demolished to accommodate a proposed
new commercial marina and boat yard. Specifically, it is proposed that a dock system consisting
of 30 slips be constructed on the site. Additionally, it is proposed that a 50-ton travel lift and
haul out facility be constructed as a part of the marina development. A boat ramp will also be
developed. The existing fish house structure will be converted for use as a marina office and
clubhouse. It is proposed that all boat maintenance activities will occur on the western side of
Orchard Creek Road on the 2.37 acre parcel of the subject property. It is proposed that no out -of -
the water boat maintenance activities occur on the subject property on the eastern side of Orchard
Creek Road. A small parking and traffic circulation area will be established on the subject
property on the eastern side of Orchard Creek Road to provide access to the docking facilities.
Otherwise, those areas currently located within the 75-foot CAMA AEC area and 50-foot Neuse
Riparian Buffer areas presently covered with impermeable surfaces will be partially re-
established with grass or other vegetation.
The existing shoreline stabilization present along Gideon Creek consists of natural marsh
shoreline areas, wood retaining walls and brick and concrete rubble. It is proposed for those
areas where brick or concrete rubble presently exist, that a new vinyl sheet piling retaining wall
be installed. Specifically, it is proposed that a total of 504 linear feet of vinyl retaining wall be
installed to replace the existing dilapidated wood and concrete retaining wall/shoreline
stabilization system.
It is proposed that no dredging occur to accommodate the proposed construction. The proposed
project is located on Gideon Creek which is classified as SA, I-IQW, and NWS Waters (Saline,
High Quality Waters, and Nutrient Sensitive Waters) by the North Carolina Department of
Environment and Natural Resources. Gideon Creek is presently closed to the taking of shellfish.
The waters of Gideon Creek are designated as a Primary Nursery Area (PNA).
It is proposed that the development as presented on the project plans be developed and
constructed in one phase of construction.
Public water service will be provided to the new dock and the existing structures to remain or to
be renovated as part of this project. Pamlico County recently upgraded the water distribution
system in the area of the project. Existing public water services exist on the site today and will
be reused to the extent possible.
No public sewer service is available in this area of Pamlico County. Two existing on -site septic
systems exist on the subject property. Each of these systems is currently permitted and
operational. It is proposed that a permit application be submitted and approved by the Pamlico
County Health Department in order to facilitate and accommodate the redevelopment of the site.
Several permits are required in order to properly execute this project. The following permits will
be secured to properly execute the project:
Erosion and Sedimentation Control Permit
2. Coastal Stormwater Permit
NPDES General Permit for Marina Operations
4. Neuse Riparian Buffer Permit/Approval
CAMA Major Permit for Marina Redevelopment
6. On -Site Septic System Permit
NCDOT Driveway Permit
8. Building Permit
The Gideon Creek project has been reviewed pursuant to the State of North Carolina Clearing
House under the provision of the North Carolina Environmental Policy Act. A "Finding of No
Significant Environmental Impact' was issued for the project on December 13, 2006 (SCH File#
07-E-4300-0164 (FONSI)). A copy of the FONSI statement is included with this narrative.

Infiltration Basim9amnd Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of inspection and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

P.E.
A. CAMA Major Permit
A CAMA Major permit is being sought in order to properly execute this project. CAMA
Areas of Environmental Concern (AEC) exist on the property. The limits of the 75 foot
AEC are delineated on the project plans. Limited development is proposed to occur
within these CAMA AEC areas as a part of the proposed upland development. Portions
of the 75 foot AEC will be disturbed in order to make the necessary site improvements.
Specifically, the shoreline area will be disturbed in order to install the proposed 504 linear
feet section of vinyl retaining wall. Additionally, some of the existing impermeable
surfaces, including structures, concrete and brick rubble and wood retaining wall system,
presently located in the 75 foot AEC area will be removed. Grass vegetation will be re-
established in the majority of these areas. The existing wood pier and dock system present
on the subject property will be removed. This dock system will be replaced with a wood -
framed dock system as presented on the project plans.
As delineated during the Environmental Assessment process, it is proposed that a total of
31,957 square feet of public trust waters be impacted by the proposed marina
redevelopment. The extent of the public trust impacts are delineated on the project plans.
The 75 foot CAMA AEC area existing on the subject property covers a total of 103,764
square feet, 2.38 acres. A total of 13,219 square feet, 0.30 acres of impermeable surface
presently exists within the 75 foot AEC area. Of these impermeable surfaces, all but
6,295 square feet, 0.14 acres of impermeable surfaces will be removed and these areas re-
established with grass vegetation. A portion of the impermeable surfaces in the 75 foot
CAMA AEC area are associated with the haul out well and access pads for the haul out
facility and boat ramp.
B. Coastal Stormwater Permit
The subject property is located adjacent to Gideon Creek. This creek, as previously stated
has a surface water classification of SA, HQW, NSW. Stormwater runoff from the
project will discharge to these surface waters. Since the receiving surface waters are
classified SA, an infiltration type system is required to comply with the Coastal
Stormwater Permitting Regulations.
The subject property covers a total area of 5.67 acres. 3.30 acres of the property is
located on the eastern side of Orchard Creek Road. The remaining 2.37 acres of the
subject property is located on the western side of the subject property. One drainage
basin exists for each of these areas.
Drainage Basin No. 1 is located on the eastern side of Gideon Creek Road. This drainage
basin covers a total area of 143,544 square feet, 3.30 acres. Presently, there is a total of
17,377 square feet of impermeable surfaces located within this drainage basin. After
development is completed, a total of 17,890 square feet of impermeable surfaces (existing
and new) will remain within this drainage basin. The percent built -upon development
within this drainage basin will be 12.46% after development. It is proposed that this
drainage basin be developed under the low density criteria of the Stormwater Regulations.
Specifically, it is proposed that the surface water runoff from the impermeable areas be
directed to discharge to points upgradient of the Neuse Riparian Buffer areas.
Additionally, it is proposed that provisions be provided to allow for diffuse flow of any
runoff from impermeable surfaces through the Neuse Riparian Buffer areas.
Drainage Basin No.2 covers a total area of 103,441 square feet, 2.37 acres. This drainage
basin is located on the western side of Orchard Creek Road. A total of 9,715 square feet
of impermeable areas exist in this drainage basin including two structures and gravel
surfacing. All but 1,728 square feet of these existing surfaces will be removed. It is
proposed that the boat yard area be constructed on this area of the site as presented on the
enclosed project plans. It is proposed that a total of 29,643 square feet, 0.68 acres of new
impermeable surfaces be created within this drainage basin. Considering the existing
1,728 square feet of impermeable to remain, the overall impermeable coverage in this
drainage basin is 31,371 square feet, or 30.3% built -upon. Since the receiving water
course in this area is classifiable as SA waters, an infiltration type stormwater treatment
system is proposed. Specifically, it is proposed that an infiltration basin be constructed to
the first 1 %2- inch of the design storm. This runoff will be routed directly to the
infiltration basin. Excess runoff will bypass the infiltration basin through a weir/drop
inlet configuration and will be routed through a vegetated swale and vegetated buffer area
to ensure diffuse and treated flow prior to entering the Neuse Riparian Buffer area. The
infiltration basin will be constructed to retain a maximum depth of runoff of one foot.
A soils investigation was completed on the subject property as part of the initial design
efforts. Hand augers were advanced in the approximate center of the infiltration basin in
order to observe soils and groundwater conditions. The soil profile encountered at this
auger location can be described as follows:

Light Brown Fine Sand
Groundwater was encountered at this auger location at a depth of approximately 36
inches below the surface. Mottling, indicated that soil wetland conditions were
encountered at depths of approximately 24 inches below the existing grade. Considering
the elevations present, the groundwater was encountered at an elevation of approximately
0.5 feet and soil and wetland conditions were encountered at an elevation of 1.0 feet. It
is proposed that two feet minimum vertical separation be provided between the soil and
wetness conditions and the bottom of the infiltration basin. The bottom of the infiltration
basin was therefore set at elevation 3.0 feet. Additionally, the confining clay layer
encountered at a depth of 24 to 42 inches within the footprint of the infiltration basin will
be removed and will be filled with a select sand fill material to encourage infiltration.
Based upon a review of soil conditions, the placement of select fill and removal of the
confining clay layer, a infiltration rate of 6.0 inches per hour was selected for the site.
C. Erosion and Sedimentation Control Permit
An Erosion and Sedimentation Control Permit application will be needed to properly
execute the project since in excess of one acre of land will be disturbed. It is proposed
that a total of approximately 3.5 acres of the 5.67 acre parcel be disturbed. It is proposed
that no wetland areas be impacted by the proposed development. Zone 1 and Zone 2
buffer areas will be impacted in order to install the bulkhead facilities, docks, haulout and
boat ramp and to remove existing impermeable surfaces within the buffer areas. Other
buffer areas will be graded and vegetation will be re-establish as indicated on the site
plan.
It is proposed that various Erosion and Sedimentation Control practices be employed on
the subject property in order to protect the surface waters, wetland areas and adjacent
property owners.
D. On -Site Wastewater Permit
There are presently two existing on -site septic systems located on the subject property. It
is proposed that each of these systems remain and be re -utilized to treat sewage generated
from the project. Since the property will be redevelop, it will be necessary to re -obtain
operation permits from the Pamlico County Health Department.
E. NCDOT Driveway Permit
An NCDOT Driveway permit will be secured for the project to make drive connections to
the public roads.
STORMWATER SYSTEM MAINTENANCE PLAN
GIDEON CREEK MARINA
4146 ORCHARD CREEK ROAD, PAMLICO COUNTY, NORTH CAROLINA
The stormwater system is defined as the (1) infiltration basin, collection system, outlet structure
and swales.
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
A. inspect the entire stormwater system for sediment accumulation, erosion,
trash accumulation, vegetated cover and general condition.
B. Check and clear all drainage devices of any obstructions such that
overflow will discharge.
Repair eroded areas immediately, re -seed as necessary to maintain full vegetative
cover, mow vegetative cover to maintain a maximum height of six -inches and
remove trash as needed.
Inspect and repair the collection system (piping, swales, rip rap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the infiltration basins semi-annually or when
sediment accumulates to reduce the design depth by 25% for each basin.
Removed sediment shall be disposed of in an appropriate manner and shall be
handled in a manner that will not adversely impact water quality.
5. If the basins must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain shall be minimized to the
maximum extent practical.
6. All components of the stormwater system shall be maintained in good working
order.
I acknowledge and agree by my signature that I am responsible for the performance and
maintenance of the Stormwater Collection and Treatment System approved and permitted for
Gideon Creek Marina, 4146 Orchard Creek Road, Pamlico County, North Carolina. I agree to
notify DWQ of any problems with the system or prior to any changes to the system or responsible
party.
