Dear Mr. Paul
John Skvarla
Secretary
On April 9, 2013, the Wilmington Regional Office received a plan revision for Stormwater
Management Permit Number SW8 120201. The revisions include changing the shape of the
forebay. The forebay area is unchanged and the storage volume increases slightly due to the
new shape. It has been determined that a formal permit modification is not required for the
proposed changes. We are forwarding you an approved copy of the revised plans for your files.
Please replace the old approved plan set with the new one.
Please be aware that all terms and conditions of the permit issued on February 3, 2013,
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 Water Quality 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 do not hesitate to call me at (910) 796-
7215.
Sincerely,
Chris Baker

Re: Plan Revision, SW8 120201, Auto Hobby Shop, AS-4060, MCAS New River
Dear Linda:
Enclosed please find our plan revision request for the above -referenced project. Enclosed
are two sets of plans, the plan modification application and revised calculation pages 3R,
4R and 5R showing no significant design change. We are revising the plan to change the
shape of the forebay in order to make room for a discharge swale associated with a
separate roadway project. The swale does not drain into this pond but passes adjacent to
it.
The pond surface area remains identical in square footage. I he temporary pool volume
and level all remain unchanged. The decanting device also requires no change. We have
updated the pond table on the detail sheet to reflect the small changes in contour area.
We appreciate your assistance with this project. Should you have any questions, please
do not hesitate to give me a call.

Stormwater Management Narrative
Auto Robby Shop, AS-4060
Schmidt Street
WAS New River, NC
(Plan Revision March 26, 2013, SWS 120201)
This project proposes the construction of a wet detention pond for an existing auto hobby
shop facility that was completed approximately two years ago. The facility includes two
buildings consisting of a garage/office facility (AS-4060) and an automated car wash
(AS-4061) in addition to the surrounding parking and traffic circulation areas. A
stormwater treatment system was not built for the facility initially since the site was
planned to result in the disturbance of less than one acre. This plan revision is changing
the shape of the forebay to make room in the area for an outlet Swale associated
with a separate roadway project being designed and permitted by others. The pond
surface area will still have the exact same square footage as originally permitted.
The project will have a wet detention pond for stormwater treatment. The pond is sized
for 90% TSS removal and will detain the treatment volume associated with the 1.5 inch
rainfall event. The project area is established as a total of 1.44 acres in size. The project
built -upon area is 69.9%. 0.5 acres of the site will be disturbed by this project in order to
construct the site improvements associated with the detention pond and the collection
system.
The wet pond is sized using the average pond depth method and comes out to an average
depth of 3.18 feet. The forebay is sized to be 20.9% (vs. 20.2%) of the pond volume
excluding the one foot sediment storage zone. The provided permanent pool surface area
of 5,766 SF exceeds the required 5,069 SF of permanent pool surface area.
The soils on the site are classified as Onslow by the Onslow County Soil Survey.
Onslow is described as a fine sandy loam and a sandy clay loam at the depths to be
disturbed by this project. The depth to the seasonal high water table at the initial wooded
boring location was determined to be 8 inches. Due to wetland concerns, the wet
detention pond was moved to the only other available area which adjoins a relatively
deep manmade drainage ditch. This area is an established grass lawn. The drainage ditch
provides a constant lowering of the groundwater level in the proposed detention pond
location. A soil boring and survey of the water table elevation indicated a stable water
table elevation of 16.5 feet due to the permanent and artificial drawdown associated with
the drainage ditch. The pond permanent pool elevation is set at an elevation of 16.5 feet.
The property is owned by the Federal Government. There have been no previous permits
issued for the work area. 'Iliere is no off -site pervious or impervious area draining into
the site.

Stormwater Management Narrative
SW8120201
The sewer system for the property is a gravity collection system discharging to the base's
treatment plant. There will be no other new utilities constructed by this project. There
are no known historic sites on the property.
The site drains to Stick Creek, a tributary of the New River. Stick Creek is classified as
SC;HQW,NSW, index 419-15. There are not any Coastal or 404 wetlands on the site.
This project does not impact any wetlands. The wetlands were delineated by Joseph C.
Avolis, PE, President Avolis Engineering, PA.
This project requires post development runoff rate control which is accomplished by the
wet pond to pre -development conditions (wooded) for the 1-year, 24-hour storm.
