Dear Andrew Shorter:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SV 7060805 for a stormwater treatment system consisting of a wet
detention pond serving the Coastal Carolina Regional Airport T-Hanger Taxi Lane ext.
and General Aviation Terminal Parking expires on December 3, 2021. This is a
reminder that permit renewal applications are due 180 days prior to expiration. We do
not have a record of receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Also, it was noted in the file review that a designer's certification that the
project was constructed in accordance with the approved plans as required by the
permit has not been submitted. Please include this with your application. Permit
application forms for renewal can be found on our website at:
https://deq. nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-construction-2. North Carolina General
Statutes and the Coastal Stormwater rules require that this property be covered under a
stormwater permit.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at

Dear Andrew Shorter
On September 26, 2018, the Washington Regional Office received a Plan Revision request for
Stormwater Management Permit Number SW7060805.
The plan revision request is for the following:
Adding 0.2 acres to the current impervious area of 3.13 acres for a total of 3.33 acres of
impervious area which is below the current permitted impervious area of 191,622 sq. ft.
Based on the current Division of Energy, Mineral, and Land Resources Guidance on this issue
your plan revision request is hereby approved. Please incorporate the approved plan set into your
existing set and permit file. Please remember that your current permit is issued 191,622 square feet of
impervious area. If at any point in future, your project exceeds the allowable impervious area the permit
will have to be modified.
Please be aware that all terms and conditions of the permit issued on December 3, 2007 remain
in full force and effect. Please also understand that the approval of this revision to the approved plans
for the subject State Stormwater Permit is done on a case -by -case basis. Any other changes to this
project must be submitted to and approved through the Division of Energy, Mineral, and Land
Resources prior to construction. The issuance of this plan revision does not preclude the permittee
from complying with all other applicable statutes, rules, regulations or ordinances which may have
jurisdiction over the proposed activity, and obtaining a permit or approval prior to construction.
If you have any questions concerning this matter, please contact me at [phone].

Dear Mr. Braaten:
This office received a Coastal Stormwater permit application and plans for the subject project on
September 21, 2007. A preliminary review of the project indicates that before a State Stormwater permit can be
issued the following additional information is needed.
Y/ I. The Stormwater Narrative states that the area of the project does not contain and is not adjacent to any
wetland area. Please provide same note on one of the Grading, Drainage and Erosion Control Plan sheets;
2. According to provided information that the impervious coverage is 32% and that the drainage area is 13.87
aaa acres, SA/DA ratio used in your calculations is not correct. You used the SA/DA ration of 4.2, which
corresponds to the coverage of 5 1 % (for Permit issued in January of 2007). Revise the calculations to show
correct SA/DA ration and revise the Narrative and any other documents to reflect this change;
/3. Despite the fact that the proposed wet detention basin is not designed in accordance with our BMP Manual,
we still need to cover the maintenance of this basin with signed and notarized Inspection & Maintenance
Agreement (found on our website http://h2o.enr.state.nc.us/su/bmp forms.htm). Please provide one;
/
✓ 4. Since this project is proposed as a modification to existing project, please revise the project name to include
the original project name and new proposed improvements. Change the name of the project on plans cover
sheet only;
✓5. Provide two sets of signed and sealed calculations and sheets.
The above requested information must be received in this office prior to December 2, 2007 or your
application will be returned as incomplete. The return of this project will necessitate resubmittal of all required
items including the application fee. If you need additional time to submit the required information, please mail
or fax your request for time extension to this office at the Letterhead address.
You should also be aware that the Stormwater Rules require that the permit be issued prior to any
development activity. Construction without a permit is a violation of 15A NCAC 21-1.1000 and North Carolina
General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.

Re: Craven County Regional Airport

Dear Samir:
Enclosed please find two copies of the revised plan cover sheet and sheet GD-1 for the
above referenced project. The cover sheet reflects the revised title of the project, which
now incorporates the original project name. Sheet GD-1 has been revised to include a
note about the presence of wetlands in the project area.
Also enclosed are two copies of the revised surface area calculation for the existing wet
detention pond. The SA/DA ratio has been changed from 4.2 to 2.68, reflecting a
decrease in the percentage of impervious surface. The project narrative has also been
revised to reflect this change. In addition, I have enclosed a red -lined copy of the Wet
Detention Basin Supplement which was submitted with the original project. This red -
lined copy shows the new drainage area, impervious surface area, and SA/DA ratio.
In addition, an Operation & Maintenance Agreement has been executed for the new wet
detention basin. This agreement has been slightly modified from the standard form
found on the DWQ website. Because this pond is not designed according to the BMP
Manual, sections of the Operation & Maintenance Agreement which did not pertain to
the modified design have been removed.
If you have any questions or need additional information, please do not hesitate to call.

J:\WPDATA\WQS\State SW-TMA\SW Application Review Checklist revised (Updated 6/18/07)

PROJECT TYPES AND SUPPLEMENTS
A. Low Density Supplement SWU-104 or SWU-105.
Applicability:
■ Low density projects may not result in built -upon surfaces in excess of 25% or 30%, depending on
the classification of the receiving stream. For calculating density with wetlands, see guidance
memo (reference document and location).
• In low density projects, stormwater Is conveyed primarily via sheet flow and swales with limited
piping for under road conveyance. Curb outlet systems may also be used in a low density project.
■ No area of the project may be configured such that it constitutes a pocket of high density. In other
words, if development is concentrated such that the undeveloped land does not significantly impact
treatment of the stormwater runoff from the developed or impervious surfaces, the low density
option may not be applied to the overall project.
• Low density projects must maintain a 30 foot wide vegetative buffer. That is, any impervious
surfaces must be at least 30 feet from surface waters, measured horizontally from the structure to
the mean high water line of the surface water.
■ All swales and related vegetated slopes must be 3:1 (horizontal to vertical) or flatter.
• Regulatory References: NCAC Title 15A, 02H.1005, 02H.1008(g).
SWU-104 is required for low density projects for which lot subdivision and selling is intended. All
sections of the supplement should be completed including the built -upon area per lot calculation.
Deed restrictions are required.
SWU-105 is required for low density projects in which curb and gutters are incorporated. All sections
should be completed including swale.design, Table 1. Supporting calculations should also be
supplied. The maintenance agreement contained within the supplement must be signed and
notarized.
B. General Permit: SWG01, SWG02, SWG03, SWG04
Applicability:
• General permits may be issued for certain groups of similar activities, including
(1) construction of single family residences (SWG01),
(2) bulkheads and boat ramps (SWG02),
(3) clearing and grading (SWG03), and
(4) linear utility projects (SWG04).
• For these types of projects, a Notice of Intent should be submitted. Upon review and approval, a
Certificate of Coverage will be issued covering the applicant under a general permit.
• Regulatory Reference: NCAC Title 15A, 02H.1013.
C. Hiah Density: SWU-102 SWU-103 SWU-106 SWU-107 SWU-108, SWU-109
General Considerations:
All runoff from the built -upon area shall be collected by swales, piping, or other means and directed
to an engineered stormwater control device or system. Runoff shall also be collected from
contributing off -site areas.
Wet ponds and infiltration basins and trenches are commonly utilized engineered stormwater
control devices. Other options include bioretention areas, extended dry detention basins,
stormwater wetlands, off -site systems, and innovative and alternative systems.

■ All systems shall be designed to meet minimum criteria, as listed in the regulations, the supplement
and in accordance with the current version of the Water Quality Section Stormwater Best
Management Practices (BMP). The current BMP manual may be viewed through a link at
• All swales and related vegetated slopes shall be 3:1 (horizontal to vertical) or less steep.'
• Operation and Maintenance plans are required for each engineered stormwater management
system, Plans are included in the respective supplements and they must be signed and notarized.
• For the purposes of operation and maintenance access, all stormwater management structures
shall be located within recorded drainage easements.
■ Plans for engineered stormwater control systems shall be prepared and sealed by a professional
engineer.
• Supporting calculations must also be signed, dated and sealed.
• One supplement shall be submitted for each drainage area.
■ Regulatory Reference: NCAC Title 15A, 02H.1008.

The most current policy (October 5, 2006) regarding the amount of wetlands that can be included
In the site area is dictated by whichever of the following two calculation methods yields the least
amount of site area:
Method 1: Calculate the acreage of the wetlands. Divide the wetland acreage by the total site
acreage, If the result is 25% or less, then the total project area. is the total site
acreage. If the result is more than 25%, then calculate the amount of wetland to
Include such that no more than 25% of the site area acreage consists of wetlands in
this manner: subtract the entire wetlands area from the site area to get the uplands
area, then divide the uplands area by 0,75.
Method 2: Calculate the area of a 100 foot wide strip of wetlands measured from the uplands
area into the wetland.
Compare the two numbers, and choose the one that yields the smallest project area.
EXAMPLE A:
Total site area = 55 acres
Total wetland area = 15 acres
►100' wide strip of wetland area = 5 acres
Method 1: 15 acres wetlands / 55 acres site = 27.3% (> 25%)
55 acres site —15 acres wetlands = 40 acres uplands
Project area for calculating density = 40 / .75 = 53.33 acres
Method 2: 55 —15 = 40
Project area for calculating density = 40 + 5 = 45 acres
Since 45 < 53.33, use area derived via Method 2 to calculate the allowable density.
EXAMPLE B:
Total site area = 55 acres
Total wetland area = 10 acres
10-100' wide strip of wetland area = 5 acres
Method 1: 1.0 / 55 = 18.2% (<25%)
Project area for calculating density = 55 acres
Method 2: 55 — 10 = 45 acres
Project area for calculating density = 45 + 5 = 50 acres
Since 50 < 55, use area derived via Method 2 to calculate the allowable density.
EXAMPLE C
Total Site Area = 55 acres
Total Wetland Area = 40 acres
►100' strip of wetland area = 15 acres
Method 1: 40 / 55 = 73% (>25%)
55 — 40 = 15 acres
Project area for calculating density = 15 / .75 = 20 acres
Method 2: 55-40 = 15
Project area for calculating density = 15 + 15 = 30 acres
Since 20 < 30, use area derived via Method 1 for calculating the allowable density.
►The 1 00'wetland strip is measured from the 401/404 line waterward (into the wetlands) of the
project for a distance of 100', or to the mean high water (MHW) line or to the property line,
whichever comes first. No credit for wetlands located outside of the property line or beyond the
MHW line can be given. By definition, the project area includes only that area above the MHW
Line.

CRAVEN COUNTY REGIONAL AIRPORT
Modification to Stormwater Permit SW7060805 NOV L 1 Z007
PROJECT DESCRIPTION AND PURPOSE ®1Y1Y&O'l AR0
This project is being completed to provide a new terminal building for the General Aviation
traffic at the Craven County Regional Airport. The existing terminal building does not provide
the space or amenities required for the increasing general aviation and corporate presence at the
Airport. As part of the project, the access road to the existing and proposed terminal buildings
will be reconstructed to address flooding issues and a new parking lot will be built. In addition, a
new grassed ditch will be constructed in the t-hangar area to help prevent flooding along
Aviation Drive and Williams Road. This new ditch will also flow to the existing stormwater
detention pond for treatment.
EXISTING CONDITIONS
This project lies within the Neuse River Basin. Currently, because of drainage problems, runoff
does not leave the site of the terminal building - the area west of Aviation Drive. Instead this
water accumulates in a large depression causing flooding problems during heavy rainstorms.
The water from the east side of Aviation Drive, including the existing stormwater detention
basin, is pumped into a large drainage ditch which parallels Runway 4-22. This ditch flows
around the end of Runway 22 and joins Scott's Creek. The area of the project does not contain -
and is not adjacent to- any wetland areas.
PROPOSED DEVELOPMENT
The current phase of development for the General Aviation Terminal Building, will create an
additional 20,773 sq.ft. of impervious surface area on the Airport property. Future development
in this area includes the expansion of the proposed parking lot. Additional future development in
the overall drainage area includes construction of the proposed hangar buildings and the adjacent
apron space in the t-hangar area, east of Aviation Drive. This future development will add an
additional 48,598 sq.ft. of impervious area to the drainage basin.
STORMWATER QUALITY ANALYSIS
Construction of the last project at the Airport (the T-Hangar Taxilane Extension project,
completed May, 2007) aimed to improve drainage problems in the t-hangar area while providing
a stormwater pond to provide treatment for all proposed development in the area. This pond was
approved under permit No. SW7060805. The design of the pond allowed for a total drainage
area of 9.52 acres with 4.82 acres of on -site and off -site impervious area, or 51%.
To provide treatment for the New General Aviation Parking and Access Road project, a
modification of the existing permit is proposed. With this modification, the total drainage area to
the existing stormwater detention pond would be 13.87 acres, however the impervious area
New General Aviation Terminal
Parking and Access Road 1 November 15, 2007

4
would be reduced to 4.40 acres, or 32%. This reduction in impervious area is due to a change in
the proposed development adjacent to the existing stonmwater detention pond.
During permitting of the T-Hangar Taxilane Extension project, the boundaries of an historic
cemetery in the t-hangar area were further explored and defined. This investigation resulted in a
much larger cemetery than what was previously believed to exist in the area. These new
boundaries resulted in a significant reduction in the scope of development completed during the
T-Hangar Taxilane Extension project, as well as reduction in the scope of proposed development
in the area. Despite these reductions, the stormwater detention pond was constructed as
originally permitted. Because of these reductions, additional capacity is available in the existing
stormwater detention pond, which could provide for treatment of the new development.
Runoff from the new development would first be contained in a wet detention basin adjacent to
the proposed parking lot, on the west side of Aviation Drive. The primary purpose of this basin
is to detain the majority of the runoff from the new development, to prevent overwhelming the
drainage system on the east side of Aviation Drive. The bottom elevation of the proposed basin
is 5.0 feet. Runoff from this area would build to an elevation of 10.0 feet in the detention basin
before draining through the proposed pipes under Aviation Drive. This will allow for significant
settlement of sediment and suspended solids prior to runoff entering the existing treatment
system. In addition, this will limit the amount of additional runoff diverted to the existing
system. This proposed wet detention basin provides a surface area of 12,837 sq.ft. and storage
volume of 47,478 cu.ft.
In addition, the entire drainage area was analyzed under two conditions. If there is no standing
water in the proposed wet detention basin, during a 10-year storm event water in the wet
detention basin will only reach an elevation of 10.05 feet, essentially containing all the runoff
from the new development and allowing the water to evaporate or infiltrate. If there is 5 feet of
standing water in the proposed wet detention basin, as if the area received back to back 10-year
storms, water in the basin will rise to an elevation of 10.88 feet, and will drain down for
approximately 72 hours. All included graphs represent the scenario with 5 feet of standing water
in the proposed wet detention basin.
The revised Water Quality Volume for this drainage area is 17,018 cu.ft., based on a total
drainage area of 13.87 acres with 32% impervious area. The existing stormwater detention pond
was built with a temporary pool volume of 18,378 cu.ft. The revised surface area required for
this drainage area is 16,192 sq.ft. The existing stormwater detention pond provides 17,470 sq.ft.
of surface area. The existing pond is adequately sized to provide treatment for the existing and
proposed development in this area.

New General Aviation Terminal Parking and Access Road
Dear Bill:
Enclosed please find two copies of the plans for the above referenced project for your review
and approval. Also enclosed are two copies of the design calculations, supporting
documentation, and soils report for the Stormwater Management Permit Application.
The New General Aviation Terminal Parking and Access Road project is being completed to
provide a new terminal building for the General Aviation traffic at the Craven County Regional
Airport. As part of the project, the access road to the existing and proposed terminal buildings
will be reconstructed and a new parking lot will be built.
We are proposing a modification of Stormwater Permit No. SW7060805 to provide treatment for
the new development. This stormwater permit was issued for the T-Hangar Taxilane Extension
project, the last project completed at the Airport. We are proposing to use the stormwater
detention pond which was constructed as part of this project to provide treatment for the new
development. I have not enclosed a new Wet Detention Basin Supplement because there were
no changes to the size of the pond. Nor have I enclosed a new Operation & Maintenance
Agreement since the existing agreement is still valid. Please let me know if you require either of
these forms for this modification.
The required check in the amount of $505.00, to cover the fee for plan review, is also enclosed.
If you have any questions or need additional information, please do not hesitate to call.

Enclosed, please find one copy of the Designer's Certification and one copy of the As -
Built plans for the above referenced project.
As you can see in the As -Built drawings, the amount of impervious area that was
constructed during this project was reduced from the amount allowed in the permit.
During the course of permitting for this project, an extensive investigation was
conducted of the limits of the historic cemetery located near the development. As a
result of this, the scope of the development had to be reduced to avoid impacts to the
cemetery. This has resulted in a reduction of the current amount of impervious area
constructed as well as a reduction in the scope of future construction.
The issued permit allows for 3.3 acres of new impervious area, including the future
hangars. The reduced scope of development will now only involve the construction of
1.2 acres of impervious area, with only 15,697 sq. ft. of that being constructed at this
point. Despite the reduced impervious area, the wet detention basin was constructed
as designed for the original permit.
If you have any questions or need additional information, please do not hesitate to call.

As requested, enclosed please find one copy of the current Airport Layout Plan (ALP)
for the Craven County Regional Airport. A revision of the ALP is currently underway,
and a draft copy should be completed within the next month. At that time I will forward
you an updated copy for your files.
Also, I have enclosed one sketch showing the proposed taxilane and hangar
development area. This sketch includes the boundary of the drainage area, preliminary
grading for the wet detention basin and the expansion of the existing stormwater pond.
The structure shown just upstream of the proposed pond will act as a diversion device
separating the first inch of runoff into the proposed pond and bypassing larger storms.
A berm with a top elevation of 6.0 feet will separate the proposed pond from the existing
and will act as an emergency spillway for the wet detention pond.
If you have any questions or need additional information, please do not hesitate to call.

PROJECT DESCRIPTION AND PURPOSE
Due to an increasing general aviation and corporate presence at Craven County Regional Airport,
additional hangar space is needed to meet the current and short-term needs of the Airport users.
The T-Hangar.Taxilane Extension project will develop a new system of taxilanes to provide
access to three future t-hangar buildings as well as seven future corporate hangars.
As well as providing new infrastructure for the Airport, this project is intended to address
flooding concerns in the General Aviation area and along Williams Road and to provide a means
of draining the roadside ditches in the area.
EXISTING CONDITIONS
This project lies within the Neuse River Basin. Water flowing from the project site is pumped
into a large drainage ditch which parallels Runway 4-22. This ditch flows around the end of
Runway 22 and joins Scott's Creek. The area of the project does not contain- and is not adjacent
to- any wetland areas.
PROPOSED DEVELOPMENT
The current phase of development for the General Aviation area, consisting of the T-Hangar
Taxilane Extension project, will create an additional 35,696 sq.ft. of impervious surface area on
the Airport property. Future development of this area, including construction of the proposed
hangar buildings and an additional taxilane will add an additional 108,891 sq.ft. of impervious
area to the drainage basin. 4 3t60, ? 3Z ae
/ r87 tf a
The additional surface runoff generated from the development will be removed via a series of
drop inlets, stormwater pipe, a wet detention basin, a stormwater control basin, and grass -lined
channels. The layout of the proposed collection system was developed through an iterative
process to achieve the most efficient removal of storm water runoff using the least amount of
materials to do so. XP-SWMM, software produced by XP Software, Inc., was selected for use in
the design of the inlets, pipe, wet detention basin, and stormwater control basin.
STORMWATER QUALITY ANALYSIS
Runoff from this drainage area includes particles from roads, hangar roofs, taxilanes, and grassed
areas. Currently, the majority of the.runoff from this area is collecting in the existing roadside
ditches along Williams Road and Aviation Drive. These ditches do not have outlets, so water
remains in the ditches until it infiltrates or evaporates. During large storms, the water elevation
in the ditches rises to the point that water is overtopping Williams Road and flooding adjacent
property owners. A small portion of runoff from this area does drain to the existing stormwater
pond, which primarily serves the remainder of the General Aviation area. This water is currently
T-Hangar Taxilane Extension 1 July 2006

being pumped into a large grass lined ditch which flows around the end of Runway 22 and joins
Scott's Creek.
To improve drainage in the area, the roadside ditch along Williams Road between Aviation
Drive and Howell Road will be re -graded to drain onto the Airport property. This ditch will
connect with a new pipe system draining runoff from the new taxilanes and future hangar
buildings. These pipes will then flow into the wet detention basin and the stormwater pond.
Prior to draining into the wet detention basin, runoff will flow through a diversion structure.
This diversion structure will have an invert one foot below the invert of the outlet pipes. This
will allow trash and large sediment to fall out prior to entering the forebay of the wet detention
basin. The outlet pipes of the diversion structure are set with a one foot separation to allow
runoff to first flow into the wet detention basin. During larger storms, when the water elevation
in the wet detention basin rises one foot, the remainder of the runoff will flow directly into the
stormwater control pond. =The=one>foof elevation-rise-corresponds`to a volume slightly -larger
Th new wet detention bas is separated from the existing stormwater pond by an earthen berm.
Water rom t e etentton basin will drain into the stormwater pond over a period of 2 days
through a 2 inch PVC pipe leading through the berm into a riser structure in the berm. The riser
structure contains a 12 inch outlet pipe leading to the stormwater pond with an invert elevation of
1.50 feet. An emergency outlet pipe with a shear gate is also provided from the wet detention
basin into the riser structure so the basin may be emptied if necessary. A trash rack. was not
provided for the 2 inch PVC pipe because it was deemed impractical for suoli a small own 'ice.
The trash ash rack was Aso omitted ebb cause of concern t a e screening device t se wou -reduce
the flow through the pipe because of the small area. In addition, a trash rack is not provided on
the riser structure in the earthen berm. This was omitted because t e nser s ru e is
mten ed to ac n over ow and the height of the structure haven set at 3 feet above
the maximum water elevation in the pond.
Once runoff reaches the stormwater pond, it will continue to be pumped out of the pond, through
a 12" PVC pipe, and into a grass ditch and swamp area which lead off of Airport property. At
the pipe outlet, there is an existing rip rap apron to prevent erosion. The trapezoidal ditch is
approximately 900 feet long with a slope of 0.50%. The bottom is approximately 5 feet wide
with 4:1 side slopes. The depth of the ditch ranges from 2 feet to approximately 6 feet at the
outfall. The ditch side slopes and bottom are currently covered with well established grasses.
The ditch bottom also has some cattail growth. During the 2-year stone, the velocity in the ditch
is 1.85 fps. The outfall of the ditch joins a low, swampy area which parallels Williams Road,
prior to joining Scott's Creek and flowing under Williams Road. This swampy area is
approximately 730 feet long, 70 feet wide, and has no slope. It also has well established
vegetation.
The existing grassed ditch and swamp area are being used in place of the 30 foot vegetated
buffer to provide the extra stormwater treatment required. This change has been made due to
space constraints and in an effort to disturb the least amount of area at the Airport. Due to the
location of the historic cemeteries on the Airport and the limited space between the Runway and
the property line, the length necessary to meet the requirements of the vegetated buffer are not
available. Based on BMP guidelines, the vegetated filter and grassed ditches provide similar
amounts of TSS removal.

Re: Craven County Regional Airport
T-Hangar Taxilane Extension
Dear Bill:
ALU 0 y 2006
Enclosed please find two copies of the plans and specifications for the above
referenced project for your review and approval. Also enclosed are two copies of the
design calculations, supporting documentation, and soils report for the Stormwater
Management Permit Application.
The T-Hangar Taxilane Extension project includes a new system of taxilanes in the
General Aviation area to provide access to three future t-hangar buildings as well as
seven future corporate hangars. As well as providing new infrastructure for the Airport,
this project is intended to address flooding concerns in the General Aviation area and
along Williams Road and to provide a means of draining the roadside ditches in the
area.
The required check in the amount of $420.00, to cover the fee for plan review, is also
enclosed.
If you have any questions or need additional information, please do not hesitate to call.
Sincerely,
THE LPA GROUP of North Carolina, p.a.
