I spoke too soon regarding the issuance of this permit. The plans do not contain
the vegetated filter detail. The forebay and pond section detail references a
vegetated filter detail, but there isn't one on the plans. Please add this detail
to the plans, and submit 2 copies of the revised plans.

I've corrected a few things on the supplement that you need to be aware of. The
first is the Basin Bottom Elevation, which you reported as 1705. 1 think you
mistakenly thought this as asking for an area, when in fact it asks for the
elevation, which is 45.0. Please confirm.
Second, page 3 was left totally blank- I have completed the sediment removal depths
and the other information. Please note that for a 3' deep pond, the sediment
removal elevation equals the bottom elevation, because the pond can never be less
than 3' deep. Essentially, there is no sediment build-up allowed in a 3' deep pond.
Upon your confirmation accepting the above changes, I can write this permit.

Dear Linda,
Enclosed are two copies of a revised stormwater plan for the referenced project and a
completed wet detention supplement form. The revised plan includes, as requested, a new
vicinity map that shows a major intersection (HWY 53 and 421). The vegetated shelf is
shown extended all the way around the pond. Also 3 wetland plants are specified by name on
the pond section detail.
Please replace the previously submitted plans and calculations with those enclosed.
Sincerely,

I received the updated stormwater wet pond calculations for the project
on September 21, 2005. Please provide the following to continue the
review:
1. I can't find a completed wet detention supplement form in the file or
in your submittal package. Gary's 8/5/2005 request for additional
information did not specifically request one, but we assumed that since
the project had been determined to be a pocket of high density, and a
wet pond was being designed, that you would know that a supplement was
necessary as well. I have attached a PDF version of the supplement to
this email for your convenience. Please complete it and have Mr. Johnson
sign, date and notarize it, and send it back to me.
2. Please update the vicinity map to show the nearest intersection of
two major roads. A 4 digit NCSR is not considered a major road.
3. The vegetated shelf is supposed to extend all the way around the
pond. The section detail appears to point at the area in front of the
forebay wall alone as the place for the wetlands plants to be planted.
The shelf and the plantings continue on around the main pond.
4. Please specify by name the wetlands plants for the vegetated shelf on
the pond section detail.
Thanks,
Linda

Dear Linda,
Enclosed are two copies of a revised stormwater plan and calculations for the referenced
project. The only thing that has changed since the recent previous submittal of additional
information is the volume used to calculate the hole sizes for the riser in the wet pond. The
revised calculations use the temporary pool volume for a 1" rainfall whereas the actual
temporary pool volume provided was used in the previous calculations. Accordingly, the plan
was revised to reflect the revised calculations. The number of riser holes changed from 6
holes to 3 holes.
Also, please notice, the calculations use the average head for orifice sizing. The maximum
head is divided in half as shown in the equations to give the average head.
I
Please replace the previously submitted plans and calculations with those enclosed.

Dear Mr. Beecher,
I received your Request for Additional Information dated August 2, 2005 today regarding Stormwater
Project No. SW8 050611.
A previous Request for Additional Information from the Division of Water Quality asked us to revise the
plans to provide a 30 foot vegetative buffer around the impervious portion of the project and to provide a
depressed grass median in the parking lot interior to address the pocket of high density. We did both of
these things, so I don't understand why additional measures are being requested.
I have spoken with Mr. Leon Johnson, President of Country Boy Riders Motorcycle Club, and we
request to meet with you on -site as early as possible. The best day for us would be as early as possible
Monday morning, August 8, 2005. Please let me know if this meeting time is acceptable or what times
you can meet with us.
Also, the "pocket of high density" determination is something I have only seen being applied in the last
couple of years. I understand the concept, but I don't know how to determine if a project has a pocket of
high density. Can you tell me where to find the rules, guidelines, definitions, or policies regarding
pockets of high density?
Sincerely,
Mark Walton

Dear Mr. Johnson:
Request for Additional Information
Stormwater Proj ect No.S W 8 050611
Country Boy Riders Motorcycle Club
Pender County
The Wilmington Regional Office received a Stormwater Management Permit Application for
Country Boy Riders Motorcycle Club site on June 7, 2005. 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. It tip ears that even with the new median this site is still a pocket of high density. An ideal
low density site would have the storniwaterfront the parking lotflowing across the softball
field. The only alternative far this site may be to go high density and add either a pond or all
infiltration basin.
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 September 1, 2005 or the
application will be returned as incomplete. The return of a project will necessitate re -submittal of
all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a
time extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information. The
Division is allowed 90 days from the receipt of a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original
documents that need to be revised have been sent to the engineer or agent. All original
documents must be returned or new originals must be provided. Copies are not acceptable. If
you have any questions concerning this matter please feel free to call me at (910) 796-7215.

Re: Stormwater Permit Application, Country Boy Riders Motorcycle Club
Dear Ms. Lewis,
Enclosed is the revised Sedimentation and Erosion Control Plan for Country Boy
Riders Motorcycle Club. The following additions/changes have been made to the plan:
1. There will be no significant changes in the existing topography of the proposed site.
Grading will only be necessary in the area of the building and parking lot. The location of
the parking lot and building have been moved in order to accommodate a 30' wide vegetative
buffer along the property lines.
2. In order to avoid "pockets of high density" a 15' grass median was added to the parking
lot. I also added a cross section detail of this median.
3. The vicinity map has been changed in order to make it more readable.
Other additions include topography lines, and other added notes regarding the topography.
Please contact me if you have any questions.

State Stormwater Permit Application
Dear Greg:
The stormwater application was received on January 25, 2005. Unfortunately, it
cannot be accepted as submitted due to the following deficiencies:
1. Please show the existing and proposed grading. Avoid creating discharge
"points". (See comment 42 below) Please utilize sheet flow only with minimum 30,
wide grassed buffers located on the property. Buffers located on adjacent
properties cannot be included since the permittee has no control over the
development of that property and cannot guarantee that the buffer will be
maintained in perpetuity.
2. This is a pocket of high density because all of the built -upon area is clustered
to one side. An engineered stormwater facility is..required if the pocket of density
cannot'be alleviated via appropriate grading, use of 30' wide grassed buffers, and
other passive control measures. A n example of a passive control measure for this
site includes a 15, wide depressed grassed median in the parking lot to store and
infiltrate runoff.
3. The vicinity map is unreadable. Please enlarge the map or enlarge the printing
to make it readable.
The application cannot be accepted until these items are addressed. If you have any
questions, you can either call me at (910) 395-3900 or email me at
linda.lewis@ncmail.net.
Sincerely,
Linda Lewis

Re: Stormwater Permit Application, Country Boy Riders Motorcycle Club
Dear Ms, Lewis,
Enclosed is the Sedimentation and Erosion Control Plan for Country Boy Riders Motorcycle
Club. This letter serves as the narrative description for the project for both the Sedimentation
and Erosion Control Plan and the Stormwater Management Permit Application.
The application is for a low -density residential development (with no curb or gutter), draining
to Class C NSW waters.
The land disturbing activity to be undertaken includes construction of a gravel road and
parking area, a softball field, a 5000 square foot building, and some grading.
Stormwater runoff will drain into the existing ditches and surrounding area by sheet flow.
Construction of the roadway will proceed as follows. First the right-of-ways will be cleared
of vegetation. A temporary construction entrance will be installed at the beginning of the
road. The road will be constructed. The unpaved area of the right-of-way will be seeded with
grass according to the specifications included with the application. The grassed areas will be
allowed sufficient time to fully develop. Once the grass in the right-of-way has been planted,
it will be maintained by Country Boy Riders Motorcycle Club.
Silt fencing will be used in areas, if deemed necessary, however it is not anticipated. Routine
inspections and maintenance will be performed to ensure that the erosion control measures are
in good condition and operating properly. Repairs will be made immediately to any erosion
control measures found to be insufficient.
