Dear Ms. Lewis:
Please find this submittal package in response to your comments received by email on
08/21,07. Your comments are listed below with our response in bold.
1. The design storm of 1.5" yields a volume of 108,694 cubic feet, not 72,466 cubic feet.
Please revise the application, supplement, calculations, and plans as needed.
• These calculations have been added to the resubmitted set.
2. The temporary pool volume to report on the supplement form is that entire volume
stored between the permanent pool elevation(PPE) and the designated(not the
calculated minimum)temporary pool elevation.
• This has been updated on the calculation sheet and page 1 of SWU-102.
3. Check the temporary pool elevation.
• The orifice size was reduced to 4-inch based on the additional volume
included to elevation 16. These corrections are shown in the calculations,
supplement and sheet C-7.2
4. The permanent pool surface area provided, as reported on the first page of the "Wet
Detention Pond Calculations", is 237,687 sq. ft, however, the surface area reported on
the supplement and used in the Stage Storage calculations is 233,476 sq. ft.
• The calculations and permit supplement have the same value 233,476 sq. ft.

Tim:
As stated in our meeting, the addinfo fees are consistently being requested. Our
disagreement stems from what you and I consider a "major" deficiency. The major
problem here is that, despite our discussion of each of the deficiencies listed in
my addinfo letter in the submittal meeting, the application was submitted with
these errors. Upon the submittal of the revised application, I have to re-check the
supplement, calculations and plans due to these comments and I have to re-run my
spreadsheet calculations. I feel that the fee is justified and I'm sorry that you
do not agree.

Linda,
I am very concerned about the additional fee in lieu of our meeting
last
Tuesday in which the fee increase is only to be implemented in a
major
design change. We were given the idea that an additional fee was
not
required for this project.
A typo on our spreadsheet based on switching to the new rules is
the
mistake we have made, and we admit such. For this pond it has no
bearing on any of the related materials in terms of changing the
orifice
size, or the weir location at elevation 16 . Also in regards to
determining the volume to be placed on SW-102, different members of
the
staff have different ideas about what value to place in this
column. We
have done such both ways in the past and had comments on both ways
of
submitting our material . We again should have asked, but again it
is
not worthy of a $2000 fee. All the updates require only an update
to
the detail sheet C-7 .2, Wet detention pond spreadsheet, and sheet 11
of
SWU-102 .
Thanks for your time.

Middle Creek Subdivision
Brunswick County
Dear Mr. Humphrey:
The Wilmington Regional Office of the Division of Water Quality received an Express
Stormwater Management Permit Applicationfor Middle Creek Subdivision on August 15, 2007.
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. The design storm of 1.5" yields a volume of 108,694 cubic feet, not 72,466.
Please revise the application, supplement, calculations and plans as needed.
2. The Temporary Pool Volume (TPV) to report on the supplement form is that
entire volume stored between the permanent pool elevation (PPE) and the
designated (not the calculated minimum) temporary pool elevation (TPE).
3. The numbers to report on the supplement are the actual provided volumes and
elevations, not the calculated or theoretical volumes and elevations. The
supplement says that the TPE is 15.3, however, the plans indicate that there is
no outlet available at 15.3. The next available outlet above the permanent pool
elevation is 16.0, or the top of the structure. Please either provide an outlet at the
designated TPE of 15.3 (or whatever elevation will give you a minimum of
108,694 cubic feet stored above the PPE — see #1 above) and recalculate the
orifice size using the correct 1.5" volume, or keep the TPE at 16 (provided it
yields a minimum of 108,694 cubic feet) and recalculate the orifice size using the
1.5" minimum volume and the higher driving head from 16 to the centerline of the
6" orifice, i.e., ((16-15.25)/2) = .375 feet.
4. The permanent pool surface area provided, as reported on the first page of the
"Wet Detention Pond Calculations", is 237,687 sq. ft., however, the surface area
reported on the supplement and used in the Stage-Storage calculations is
233,476 sq. ft.
5. Please include a resubmittal fee of$2000.00 with the revised application
materials. All of the above items were discussed at the submittal meeting.

RE: Middle Creek Stormwater Submittal
Dear Ms. Lewis:
Please find this submittal package in response to your comments received by email on
08/14/07. Your comments are listed below with our response in bold.
1. I questioned the use of such a deep pond(15', in some places) as a viable stormwater
pond. I sent an email up to the Washington&Raleigh stormwater staff to see if they
have any comments on that issue.
• Noted.
2. Provide the completed, signed, dated and notarized deed restriction document for high
density subdivisions, attached.
• Please find in the submittal package a copy of the Declaration of Covenants,
Conditions, and Restrictions for the Middle Creek Community. Article XII,
Section 4 contains the same language as the form provided; please find this
as sufficient.
3. Revise the orifice sizing based only on the 1.5"minimum volume.
• After revisiting the calculations we have found that a 6" orifice is in fact
necessary to drawdown the temporary pool within the required time period.
At first glance during our meeting I assumed that the orifice was sized based
on the entire volume below the temporary pool since it was so large, but
from re-examining the spreadsheet and performing hand calculations,the
orifice was in fact sized correctly to drawdown the 1.5" runoff volume. The
1.5" runoff volume is 72,466 cf; this volume will result in a temporary pool
elevation of 15.30. (Permanent pool=EL. 15.00). Using the average head
above the orifice,the flow rate through the 6" orifice is 0.37 cfs; to
drawdown the 1.5" runoff volume of 72,466 cf it will take approximately
2.29 days.
4. Provide dimension for the entrance road and a note on the plans regarding whether the
dimensions are to the face of curb or the back of curb.

a note has been added to the plans.
5. Add dimensions and radii for the permanent pool contour of the pond.
• Please find on sheet C-4.3 that the permanent pool contour of the pond has
been labeled.

MIDDLE CREEK SUBDIVISION
SHALLOTTE, NORTH CAROLINA
Project#06117.PE
DESIGN NARRATIVE
Bill Clark Homes, LLC proposes to develop a subdivision on a 56.36 Ac. parcel in Brunswick
County, North Carolina. The project is located approximately 0.12 miles east along Village
Point Road (SR 1145) from the intersection of Village Point Road and Bay Road (SR 1151) in
Shallotte.
The southern portion of the property can be best described as dense tree cover and as you
move north the ground cover becomes more sparse until it is completely open near the existing
pond onsite. The site currently drains to Middle Dam Creek and according to the NRCS Soil
Survey of Brunswick County the soil for the site consists of Baymeade fine sand (BaB), Blanton
fine sand (BnB), Norfolk loamy fine sand (NoB), with patches of Murville mucky fine sand
(Mu), and Rains fine sandy loam(Ra).
The proposed residential community will consist of 114 single family lots,roads,and sidewalks?
as illustrated on the plans. All stormwater runoff will be conveyed by a storm sewer system to
a wet detention pond where it will be treated and stored per NCDENR and the Town of
Shallotte stormwater regulations.
Note that the wet detention pond proposed is actually an existing pond that has been reshaped
for proper side slopes and a vegetative shelf at permanent pool. The pond is substantially
larger than what is required to serve the development, therefore a non conventional approach
for the NCDENR stormwater treatment requirements needs to be employed. Please note that
the forebay has been designed to be 20% of a conceptual total pond volume of a pond that
meets the surface area requirements of the drainage area and not 20% of the total actual pond
volume. In short, the forebay is sized to treat the stormwater relative to the quantity of the
stormwater draining to the pond and not sized based on the volume of the reshaped existing
pond. In addition, the design depth of the permanent pool has been designed to be an average
depth of 6'; from visual inspection there are some areas of the pond much deeper than 6', but
we used this average depth to be conservative since the actual depth of the pond would be off
the SA/DA ratio charts. Last, the pond outlet structure has been placed strategically along
Middle Dam Creek in order to safety outfall to the creek and not across the pond to outfall on
adjacent properties. As a result it may appear that the stormwater is short-circuiting the
treatment process, but that is not the case. To achieve the required surface area of a wet pond
based .'n the area draining to it, a pond length of 350 ft is needed to treat the runoff; the
proposed pond length from the inlet to outfall is approximately 550 ft, allowing sufficient
contact time of TSS removal. IECEIVED

Wet Detention Pond Calculations
NC DENR Retention Requirements
Objective:design a wet detention basin with the following characteristics:a permanent water pool depth between 3-and
6-feet, a surface area that meets TSS removal requirements(values set by NC DENR and included here), a forebay that
is approximately 20%of the total pond volume, a temporary water pool sized to detain the initial 1.5 inch of rainfall runoff, an
outlet device that drains the temporary water pool within 2-5 days, and a length-to-width ratio of approximately 3:1.

One thing I forgot to mention is that from now on, the permittee must attend the
submittal meetings. Please make sure your clients are aware of this requirement.
As we discussed at the submittal meeting for the subject project this afternoon,
the following items need to be addressed by close of business August 15, 2007, in
order to accept the project for review in the Express program:
1. I questioned the use of such a deep pond (15' , in some places) as a viable
stormwater pond. I sent an email up to the Washington & Raleigh stormwater staff to
see if they have any comments on that issue.
2. Provide the completed, signed, dated and notarized deed restriction document for
high density subdivisions, attached.
3. Revise the orifice sizing based only on the 1.5" minimum volume. **One thing we
did not discuss was to use the average head for that calculation between the
permanent pool elevation (PPE) and the specified temporary pool elevation, which is
the next available outlet above the PPE.**
4. Provide dimensions for the entrance road and a note on the plans regarding
whether the dimensions are to the face of curb or the back of curb.
5. Add dimensions and radii for the permanent pool contour of the pond. I know it's
irregular, but do the best you can.
Thanks,
Linda

Can any of you remember what (if any) problems we have with using existing mining
or borrow pits as state stormwater ponds? These are generally very deep waters (>20
feet in some cases) with 10 times or more as much surface area as the required
minimum. The twice a year thermal inversion is a potential concern, but I can't
remember if there was a cutoff depth at which this was not an issue.

The subject project has been scheduled for an Express Review Submittal
meeting with Mary Jean Naugle on Tuesday, August 14, 2007 at 9:30 am.
Please respond within 2 business days to confirm and reserve this
meeting date and time. No further notification will be sent. If you need
to reschedule, please advise ASAP.
Please be reminded that where ponds are to be located adjacent to
wetlands, you will need to address the SHWT issue and demonstrate that
the permanent pool level proposed in the pond is not below the SHWT such
that the wetlands will be drained off over time. Additionally, please
bring the wetlands delineation map to the submittal meeting.

Middle Creek
Express Stormwater Narrative
May 31, 2007
Project Narrative:
Bill Clark Homes of Wilmington is proposing to develop a 56.4 acre residential development
(114 lots)in Shallotte. The site is located on Village Point Road in Shallotte. The site is currently
a combination of open area and woods.
The project is within a drainage basin that drains Middle Dam Creek(SC;HQW). All
stormwater will be captured by a storm sewer system which will serve to convey the runoff into
a wet detention pond for treatment and storage. The wet detention pond has been designed to
meet the Town of Shallotte Stormwater Ordinance and NCDENR's design requirements.
