Dear Mr. Nunnelee:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Coastal Beverage Addition, Wilmington, NC on May 26, 2006. Staff review of

MESSAGE:
There are just a few items needed for the Coastal Beverage permit.
Please update the drainage area map. It does not include the new portion of
the pond. Also, the drainage area listed in the applicationlcalcs is the same
as was originally submitted, when it appears to have increased with the new
pond configuration.
2. Please either dimension all BUA within the permitted DA or the DA itself (1
realize this is in conflict with what was discussed on 4/25 — I have been
corrected. We will need this info.) Probably the easiest was to do this is to
dimension the DA by utilizing and expanding on the DA dimensions already
provided along the property boundary -- the DA is relatively angular and
should not be too difficult to dimension.
3. The DA map does not appear to be entirely supported by the contour
information provided. Specifically:
o The elevations shown for the S & SW portion of the new gravel
area do not clearly show all of that runoff will drain to the SD
system and into the pond. Some runoff may flow into the new SD
that bypasses the pond.
o There is no contour information provided around the new parking
area at the SW portion of the project area — no way to verify DA.
o The spot elevations around the maintenance facility appear to.show
the DA along the edge of the facility
o There is nothing to show offsite runoff does not enter the site.
**PHIL** - Clearly, you drew the DA where you did for a reason; if you have spot
elevations to support the above concerns, please put them on the drawings. I
will make a field visit either today or Monday to verify the DA on the existing
portions of the site — this will likely clear up the last 3 bullets. If you obtained the
DA via field verification, please add a note to the drawing indicating that.
Because the gravel parking area is going to change from existing (however
slightly) I cannot field verify the first bullet.

Coastal Beverage Addition
New Hanover County
Dear Mr. Nunnelee:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Coastal Beverage Addition on April 13, 2006. A preliminary review of that information has
determined that the application is not complete. The following information is needed to
continue the stormwater review.
1. Gary R. Nunnelee is the only ManageF listed with the Secretary of States office as being
affiliated with Nunnelee Properties,"LLC.�Tuney Nunnelee is not listed. Please have
Gary Nunnelee sign the application or provide documentation that Tuney Nunnelee is a
Manager. /
2. Please dimension all proposed BUA 'within the drainage area.
3. It is very difficult to tell what is proposed vs. existing -and pervious vs. impervious.
Please clarify. Also, the drainage area was designed for 100% impervious. Is what is
currently proposed within the drainage area,1�00% impervious? There appears to be at
least a few areas that are pervious (lands'cape islands) within the drainage area. If the
system was simply designed at 1006/76impervious but is currently proposing less, please
indicate this on the application.
4. Please include the amount of existing impervious area within the proposed pond
drainage area on Section ill (6) of the application (only the portion that is to remain).
5. Provide some roof drain detail to show roof drains will direct runoff within the permitted
drainage area to the pond.
6. Please add a North arrowtothe drawing.
7. Please add a note indicating there are no wetlands present on the site (or show them if
they do exist).
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to May 2, 2006, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.

NARRATIVE
DESCRIPTION:
The project site is a developed tract located off of Harley Road in Wilmington,
North Carolina. The soils of the site consist of lightly vegetated, sandy clay topsoil and
grades ranging from 0.5% to 2.0%. Approximately 3.0 acres will be graded to allow
construction of a new building addition with paved parking and paved access. The
runoff from the site is estimated using the rational method 10-year and 25-year design
storm and rainfall data for the area. Construction is scheduled to begin as soon as all
permits and approvals are obtained.
EROSION CONTROL MEASURES:
The attached plans and specifications outline the requirements for erosion
control measures. Silt fencing will be provided along each side of the entrance drive
where stormwater would be expected to sheet flow from disturbed areas directly to
adjacent property. The detention pond will be used as a silt basin during construction
and restored to its design contours prior to completion. A gravel construction entrance
will be constructed at the main entrance. Maintenance will be provided by the grading
contractor and developer.
STORMWATER MANAGEMENT MEASURES:
The project site is located in New Hanover County. Land disturbing on the site
will exceed one acre; which requires the site to comply with the State .Regulations. The
stormwater runoff from the development will be directed to the proposed stormwater
detention pond_
CONSTRUCTION SEQUENCE:
The Contractor will install the gravel construction entrance and sift fence prior to
beginning any clearing and grading operations. Additional silt fence will be installed
when and if conditions warrant during construction. The detention pond/silt basin will
be constructed immediately after that portion of the site is cleared, and outlet structure
with protection will be installed. Disturbed areas will be landscaped or seeded upon
completion_
EROSION CONTROL NOTES AND MAINTENANCE PLAN
Install erosion control measures before beginning construction or as .soon
thereafter as possible. All erosion and sediment control practices will be
checked for stability and operation following every runoff -producing rainfall but in
no case less than once every week. Any needed repairs will be made
immediately to maintain all practices as designed.
2. - Maintain the gravel construction entrances in a condition to prevent mud or
sediment from leaving the construction site. The contractor shall inspect the
construction entrances on a daily basis. This will require periodic top dressing
with additional No. 4 stone. Any objectionable materials spilled, washed, or
tracked onto public roadways shall be removed immediately.
3. Install erosion control measures around the drop inlets as shown on the plans to
trap silt during construction. Inspect the erosion control around the inlets after
each rain and make repairs immediately. Remove sediment when it becomes
0.50 deep to provide adequate storage volume for subsequent rains. When the
contributing drainage area has been adequately stabilized, remove all materials
and any unstable soil and either salvage or dispose of it properly. Bring the
disturbed area to proper grade and appropriately stabilize all bare areas around
the drop inlets:
4. Sediment will be removed from behind the silt fence when it becomes 0.5 feet
deep at the fence. ' The sediment fence will be repaired as necessary to maintain
a barrier. Silt fence stakes shall be spaced 6 feet apart unless a wire backing is
used with 8 foot stake spacing.
5. Inspect temporary sediment traps / check dams after each period of significant
rainfall. Remove sediment and restore the trap to its original dimensions when
the sediment has accumulated to one-half the design depth of the trap. Place
the sediment that is removed in the designated disposal area and replace the
contaminated part of the gravel facing. Check the structure for damage from
erosion or piping. Periodically check the depth of the spillway to ensure it is a
minimum of 1.5 ft below the low point of the embankment. Immediately fill any
settlement of the embankment to slightly above design grade. Any riprap
displaced from the spillway must be replaced immediately. After all sediment -
producing areas have been permanently stabilized, remove the structure and all
unstable sediment. Smooth the area to blend with the adjoining areas and
stabilize properly_
6. The stormwater ponds will act as sediment basins and will be cleaned out when
the level of sediment reaches 2.0 ft below the top of the riser. Gravel will be
cleaned or replaced when the sediment pool no longer drains properly_
03/15/2006 WED 12:50 FAX 91U 343 W4 Morris, husKe, itinstan
C' UUJ! VVJ
7. The angle for graded slopes and filis shall be no greater than the angle that can
be retained by vegetative cover or other adequate erosion -control devices or
structures. In any event, slopes left exposed will, within 21 calendar days of
completion of any phase of grading, be planted or otherwise provided with
temporary or permanent ground cover, devices, or structures sufficient to restrain
erosion.
8. All disturbed areas shall be seeded within 15 days of disturbance. All seeded
areas will be fertilized, reseeded as necessary and mulched according to
specifications in the vegetative plan to maintain a vigorous, dense vegetative
cover.
9. More stringent measures shall be used to halt erosion if those shown on this plan
are -not effective.
10_ All erosion shall be controlled including side slopes before the project is
completed.
11. Remove temporary measures upon completion of project. All permanent
measures will be well established before project closeout.
