Dear Commander McKerrall:
The Wilmington Regional Office received the Stormwater Management Permit Application for Tactical Support Van Pad
on August 21, 1997, with final information on December 1, 1997. Staff review of the plans and specifications has
determined that the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC
2H.1000. We are forwarding Permit No. SW8 970847 dated January 28, 1998, for the construction of Tactical Support
Van Pad.
This permit shall be effective from the date of issuance until January 28, 2008, and shall be subject to the conditions and
limitations as specified therein. Please pay special attention to the Operation and Maintenance requirements in this permit.
Failure to establish an adequate system for operation and maintenance of the stormwater management system will result
in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This request must be
in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the

SUBJECT: N.C. DEHNR Water Quality Section final review comments dated
7 Nov 97 on the Stormwater Management permit application for the referenced, DEHNR
Stormwater Project No. SW8 970847
The following changes have been made to the stormwater management plan as the result
of a meeting held at the NCDENR Division of Water Quality Wilmington office on 19
Nov 97 with Ms. Linda Lewis:
1. The forebay has been enlarged to exceed the minimum 20% of the total first I"
volume of runoff as follows;
Total first 1" runoff volume = 31,468 cu. ft. (from original calculations)
Revised forebay volume = 8,000 cu. ft.
% of first 1" runoff volume = (8,000/31,468) X 100% = 25%
2. The 0.9 acre drainage area along the Access Rd. adjacent to the van pad will be
allowed to drain into the existing canal with the inclusion of the 2.2 acres from the
existing off -site parking lot into the pond. This arrangement is described<in the
previously submitted Stormwater Management Pond paragraph of the Narrative
accompanying the calculations. There is no change to the plans.
3. Future development must include considerations for stormwater management for the
southern portion of the access road as well as the remaining tract. The drainage
system shown on sheet C4 is reconfigured to accommodate this requirement.
4. Two copies each of sheets C4, C7, and C 13 are attached with a copy of this memo
and forwarded to Ms. Lewis at the NCDENR Division of Water Quality office in
Wilmington. It is our understanding that the stormwater management plans will be
approved upon successful review of this submittal.

SUBJECT: N.C. DEHNR Water Quality Section review comments on the
Stormwater Management permit application for the referenced, DEHNR Stormwater
Project No. SW8 970847
The following responses are offered:
Item 1. It was intended that 3 sets of plans, accompany the initial application package.
Since this did not occur, two new sets of plans are attached for DEHNR use. Several
minor changes and corrections have been made as a result of the Water Quality Section
comments and in-house reviews. None of these changes impact the
erosion/sedimentation control permit application submittal.
Several changes have been made to the narrative page (paragraphs I, II, and III) and to the
stormwater management summary sheet of the original application. Replace the old
pages with the attached copies.
Item 2. The 10.08 acres of drainage breaks down as follows:
A. Current Site= 5.58 acres
B. Existing (off -site) = 2.2 acres
C. Future Development (also off -site) = 2.3 acres
Two copies of the revised stormwater design work sheet, sheet SDO1, are attached. This
sheet delineates the indicated areas.
Item 3. The orifice size has been reduced to 3" (75 mm-nominal) (schedule 40 pvc).
Two copies of the revised Stormwater Management Calculations (page 2(continued)) are
attached. Plan sheet C13 has been revised accordingly.
Item 4. A note indicating no wetlands has been added to sheet SDO1 (2 revised copies
attached) as requested. Replace the old sheet SDO1 with an attached copy.
Item 5. The information requested is shown on plan sheets C4, C5, C6, and C7 of the
attached drawings.

Item 6. The information requested is shown on plan sheets C3 and C7 of the attached
drawings.
Item 7. The information requested is shown in details on plan sheet C13 of the attached
drawings.
Item 8. The information requested is shown in detail B, plan sheet C13 of the attached
drawings.
Item 9. Section III has been revised with the information requested and 2 copies of the
revised application page are attached.
Item 10. The impervious area in the application should have reflected the area (7.06
acres) shown in the design calculations. The breakdown requested in item 9 reflects the
proper area.
Item 11. We acknowledge this requirement. Sheet C7 has been revised to show a pipe
stub for this future work.
The other portions of the original application package remain as submitted.

D E M
PROJ #
The purpose of this project is to construct a concrete pad for storing mobile facilities
(vans) used in forward deployments. In addition, a small head (restroom), open
storage shelter, parking area, and access roads are provided. Total site area is
approximately 8.85 acres including the proposed impervious areas and a 1.85 acre
stormwater management pond. The proposed site is located on a largely undeveloped
15 acre (+-) tract of land bounded by Canal St. on the west, Campbell St. on the north,
White St. on the east, and Douglas St. on the south. This project is one of several
planned for this area. The access road, canal crossings, and stormwater management
pond are designed to facilitate future development. Access to the site will be
provided by two canal crossings whose location is dictated by existing elevated
sections of a steam line parallel to the existing canal. The southernmost portion of the
access road is for future development.
SITE DESCRIPTION
The site is relatively flat with incidental runoff to the existing canal along the west
side of the project. The overland flow will be collected into 375mm through 900mm
diameter storm drain pipes and routed into the new detention pond. The storm water
will flow from the pond approximately 46 meters into the existing canal. A concrete
headwall with rip rap is provided to stabilize the existing canal bank.
Two canal crossings are.provided. Twin 1500mm culverts with headwalls are
provided at each crossing.
STORMWATER MANAGEMENT POND
A 1.85 acre wet detention pond is provided to treat runoff from the proposed
development and a future 2.3 acre site north of this project in accordance with 15A
NCAC 2H.1000. A piped stormwater collection system will route the site runoff to
the pond for treatment. Outflow from the pond will flow into the existing canal along
Canal Street on the west side of the project. The pond is designed to comply with the
requirements of 15A NCAC 2H.1000.
Four small adjacent drainage areas along the access road (0.9 acre total) cannot be
configured to drain to the pond. They are instead drained into the existing canal. To
compensate for this limitation the pond will treat runoff from the existing 2.2 acre
parking lot upstream. Future development will include considerations for stormwater
management for the southern portion of the access road as well as the remaining tract
area.

SUMMARY
The proposed stormwater management facility is a Wet Detention Pond designed for
90% removal of TSS. The pond has a forebay and a vegetative strip at a 6:1 slope. The pond
side slopes are at 4:1 The stormwater management pond is designed to treat storm drainage
run-off from; 2.2 acres from a future development to the north and all of the site area
excluding the adjacent access road areas (0.9 acre);. The site configuration does not allow
this small area to be routed into the pond. To compensate for this limitation, the pond will
include 2.4 acres of drainage from an existing adjacent parking lot. The pond discharge is
piped into the existing canal along Canal Street. This canal flows into Southwest Creek
which drains into the New River. The following is a summary of the pond design
parameters:
1 - Basin surface area required (SA) = 26,572 sf
provided (SA) = 37,410 sf
2 - Drainage area (DA) = 10.08 Ac.
3 - SA/DA ratio required = 0.060
provided = 0.085
4 - Pond depth = 4 feet
5 - % impervious = 70
6 - Temporary water quality pool volume required = 31,468 CF
provided = 33,209 CF
The outlet pipe velocity was also analyzed with respect to discharge impacts. It was
found that the proposed outlet pipe has a 10 year storm outlet velocity of 4.1 FPS. The
outlet velocity will quickly dissipate and disperse across the stone riprap provided.

Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 970847
MCAS Tactical Support Van Pads
Onslow County
Dear Mr. Hoyt:
The Wilmington Regional Office received a Stormwater Management Permit Application for MCAS
Tactical Support Van Pads on August 21, 1997. 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. Two sets of plans are required for submittal. Only 1 was received.
t/ 2. Please breakdown the 10.08 acres of drainage to current site, existing (off -site) and future
development.
;/ 3. Do not round up the size of the orifice found using the 2 day time. The orifice is already as
large as it can be. You must round down, or calculate the size required for a 5 day drawdown,
and choose one inbetween.
/4. Delineate all wetlands on site, or note on the plans that none exist.
15. 5. Please provide a grading plan with existing and proposed contours, spot elevations, and catch
basin tops and inverts in order for this Office to verify drainage.
6. Provide dimensions for the proposed van pads, and for the permanent pool of the pond. The
pond sizing calculations cannot be verified until this information is received.

9. In the "Breakdown of Impervious Area" in Section III of the application, please list the built -
upon area individually for the current site, the existing (offsite) area,. and the future
development.
10. The impervious area on the application, 4.75 acres, is less than the impervious area in the
calculations, 7.06 acres. If the pond is designed for 7.06 acres, then 7.06 acres needs to be
on the application. See comment #9 above.
11. Future development will be required to send it's runoff into the pond -at the forebay. Short-
circuiting will not be allowed.
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 October 19, 1997, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.

PROJECT DESCRIPTION
The purpose of this project is to construct a concrete pad for storing mobile facilities
(vans) used in forward deployments. In addition, a small head (restroom), open
storage shelter, parking area, and access roads are provided. Total site area is
approximately 8.85 acres including the proposed impervious areas and a 1.85 acre
stormwater management pond. The proposed site is located on a largely undeveloped
15 acre (+-) tract of land bounded by Canal St. on the west, Campbell St. on the north,
White St. on the east, and Douglas St. on the south. This project is one of several
planned for this area. The access road, canal crossings, and stormwater management
pond are designed to facilitate future development. Access to the site will be
provided by two canal crossings whose location is dictated by existing elevated
sections of a steam line parallel to the existing canal. The southernmost portion of the
access road is for future development.
SITE DESCRIPTION
The site is about 75% covered with small pine trees except for the existing dirt road
along the western side adjacent to the canal. The ground is relatively flat with
incidental runoff to the existing canal along the west side of the project. The overland
flow will be collected into 375mm through 900mm diameter storm drain pipes and
routed into the new detention pond. The storm water will flow from the pond
approximately 46 meters into the existing canal. A concrete headwall with rip rap is
provided to stabilize the existing canal bank.
Two canal crossings are provided. Twin 1500mm culverts with headwalls are
provided at each crossing.
STORMWATER MANAGEMENT POND
A 1.85 acre wet detention pond is provided to treat runoff from the proposed
development and a future 2.2 acre site north of this project in accordance with 15A
NCAC 2H.1000. A piped stormwater collection system will route the site runoff to
the pond for treatment. Outflow from the pond will flow into the existing canal along
Canal Street on the west side of the project. The pond is designed to comply with the
requirements of 15A NCAC 2H.1000.
Four small adjacent drainage areas along the access road (0.9 acre total) cannot be
configured to drain to the pond. They are instead drained into the existing canal. To
compensate for this limitation the pond will treat runoff from the existing 2.4 acre
parking lot upstream as well as include the 0.9 acre in the pond sizing calculations.

Future development will include considerations for stormwater management for the
southern portion of the access road as well as the remaining tract area.
SOILS
The soils existing on the site are generally in three groups as follows- 1)The surface is
covered by a 6" thick layer of soft dark brown organic fine sandy silt with roots. This
layer was soft and wet at the time of drilling. The thickness vanes, extending to a
depth of 3' in some locations. 2)Beneath these soils and extending to depths of 6' to
9' are layers of brown and orange fine sandy clay. Present within this area are layers
or lenses of fine sand. 3)A soft highly plastic clay extends below the group 2 soils to
termination of our borings. This clay is replaced by fine sand along the southern edge
of the Van Pad site. The clay sand interface appears to dip down to the north, with a
slight rise or peak in the vicinity of borings B6 and B8.
Groundwater elevations vaned considerably during exploration, from being
encountered at the ground surface to dry at 10.5'. Much of the groundwater
encountered is thought to be perched, as the nearby ditch is approximately 10' deep
and water was not standing in it. The uppermost soils are considered to be of
moderate erosion hazard and of low permeability, except moderate to high
permeability where the sand layers or lenses are exposed.
PLANNED EROSION AND SEDIMENT CONTROL PRACTICES
1. Temporary Gravel Construction Entrances; 4 are provided to allow ample site
access.
2. Inlet Protection; is provided for all affected inlet structures.
3. Temporary Sediment Fences; are provided around the entire construction site.
4. Temporary Sediment Containment; The wet detention pond may be used for
temporary sediment containment during construction. The pond will be cleaned
of all eroded materials, trash, and sediment at the completion of the project.
5. Rip Rap; is provided at the detention pond outfall into the existing canal.

F - STORMWATER MANAGEMENT SUMMARY

SUMMARY
The proposed stormwater management facility is a Wet Detention Pond designed for
90% removal of TSS. The pond has a forebay and a vegetative strip at a 6:1 slope.
The pond side slopes are at 4:1 The stormwater management pond is designed to treat storm
drainage run-off from; 2.2 acres from a future development to the north and all of the site
area excluding the adjacent access road areas (0.9 acre);. The site configuration does not
allow this small area to be routed into the pond. To compensate for this limitation, the pond
will include 2.4 acres of drainage from an existing adjacent parking lot. The pond sizing
calculations do include the 0.9 acre from the access road. The pond discharge is piped into
the existing canal along Canal Street. This canal flows into Southwest Creek which drains
into the New River. The following is a summary of the pond design parameters:
1 - Basin surface area required (SA) = 26,572 sf
provided (SA) = 37,410 sf
2 - Drainage area (DA) = 10.08 Ac.
3 - SA/DA ratio required = 0.060
provided = 0.085
4 - Pond depth = 4 feet
5 - % impervious = 70
6 - Temporary water quality pool volume required = 31,468 CF
provided = 33,209 CF
The outlet pipe velocity was also analyzed with respect to discharge impacts. It was
found that the proposed outlet pipe has a 10 year storm outlet velocity of 4.1 FPS. The
outlet velocity will quickly dissipate and disperse across the stone riprap provided.

:Mr. James E. Butler, PE
Department of the Navy - Atlantic Division
Naval Facilities Engineering, Command
1510 Gilbert Street
Norfolk, Virginia 23511-2699
Dear Mr. Butler:
3620 SIX FORKS ROAD
RALEIGH, N.C. 27609
[phone]
19191761.9547
In accordance with your written request of March 25, 1993, I am enclosing,
for your information a copy of The North Carolina Engineering and Land
Surveying Act, G. S. 89C.
I will refer your attention to G. S. 89C-25 which provides limitations on the
application of the Statute. Paragraph 6 specifically exempts "Practice by
members of the armed forces or employees of the government of the
United States while engaged in the practice of engineering or land
surveying solely for said government on government -owned works and
projects."
Tnis exemption should not be construed as to allow engineering services to
be provided to the Department of the Navy by non -registered contract
employees. For any such circumstance, a North Carolina registrant would
need be in responsible chase of any engineering services ro be provided for
a North Carolina project.
I trust this information will be of some service and ask that you contact me
if this office can be of further assistance.

?7iry. Carter
