Dear Due Nguyen:
This letter is to inform you of certain conditions of your stormwater permit that have not been met. In accordance with
Title 15A NCAC 21-1.100, the Stormwater Management Regulations, deed restrictions and protective covenants are
required where lots will be subdivided and sold. Deed Restrictions and protective covenants are necessary to ensure that
the development maintains a "built -upon' area consistent with the applicable regulations governing the density level.
A DWQ file review confirms that copies of the recorded deed restrictions have not been provided to this Office. Failure to
record the required deed restrictions constitutes a violation of Permit Number SW7090905 which states "Deed restrictions
are incorporated into this permit by reference and must be recorded with the Office of Register of Deeds prior to the sale
of any lot. In addition, a copy of the recorded restrictions must be received by this Office within 30 days of the date of
recording. Recorded deed restrictions must include as a minimum certain statements related to stormwater management
as outlined in both the permit and the notarized statement signed by the applicant at the time of permit request submittal.
Please provide proof of these required deed restrictions to this Office at the address listed on the letterhead within 30 days
of receipt of this letter. If you have any questions regarding this matter, please contact Amy Adams at [phone].

Subject: Stormwater Review SW7090905 Modification
Musashi Restaurant and Office Complex
Craven County
This office received a Coastal Stormwater permit Modification application and plans for
the subject project on April 19, 2010. A preliminary review of your project indicates that before a
State Stormwater permit can be issued the following additional information is needed:
1. It appears that the total depth of wet pond is used in SA/DA tables instead of
Average Pond Depth of 3.0'. Please revise.
2. Please revise the Required Surface Area of the pond and subsequently Provided
Surface Area of the pond due to use of total pond depth (see note 1).
3. As proposed the flow in wet detention pond will short circuit. Please redesign the
pond to avoid short-circuiting.
4. According to NC Stormwater BMP Manual, the forebay should be 3.0' deep and has
to contain about 20% of Permanent Pool Volume. The current proposal does not
meet these requirements. Please redesign.
5. Please consider the different location for forebay rather than one proposed. The
proposed location of forebay and forebay berm is reducing the width of a portion of
vegetative shelf and creates short-circuiting concern. Please make sure that all of
the impervious area runoff is collected into the forebay.
6. Please address the issue of erosion of forebay berm.
7. According to current proposal. The southern most corner of the parking might not
drain to wet pond. Please revise.
8. Please be advised that prior to installation of 3,500 s.f. of approximate future
impervious area, revised plans will have to be submitted to us for approval.
9. Provide two copies of signed and sealed revised sheets.
The above requested information must be received in this office prior to June 18, 2010
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 me at the
Letterhead address and include the application number on the request. The request must
include justification for the amount of additional time needed. The request will only be granted
for justifiable delays that are unforeseen and beyond the owner or consultant's control.

Dear Mr. Dumpor:
JUN. 0.92010
.. off• `�.�'
Thank you for your help with this project. We received your review and have addressed
your concerns as follows. Please note where possible, revisions made to text are shown in red.
Comment 1: It appears that the total depth of wet pond is used in SA/DA tables instead
of Average Pond Depth of 3.0'. Please revise.
Response 1: The average pond depth is 3 feet and the actual depth is 6.9 feet, 24 17.1.
Per an average pond depth, based on Coastal Table 10-3 and 90% TSS removal, a
SAIDA value of 6.5 was used to calculate the revised pond parameters. Attached are
revised forms, drawings and calculations based upon the revised parameters, including
calculation spreadsheet and Wet detention pond supplement and narrative.
Comment 2: Please revise the Required Surface Area of the pond and subsequently
provided Surface Area of the pond due to use of total pond depth (see note 1).
Response 2: The surface area has been revised to account for revised SAIDA. Please
see revised drawings, calculations and forms, including calculation. spreadsheet and
Wet detention pond supplement and narrative
Comment 3: As proposed the flow in wet detention pond will short circuit. Please
redesign the pond to avoid short-circuiting.
Response 3: The wet pond has been lengthened to avoid short-circuiting, please see
Sheets SP-1 and SP-3.

Wet Pond Permit ModiFcation SW7090905
219 US Highway 70, Havelock, Craven County, North Carolina
WET POND NARRATIVE -INTRODUCTION
This narrative discusses the wet pond permit modification application for the Musashi Restaurant and
Commercial Office project. The plan includes construction of a 5,000 sq.ft., slab on -grade building, including
V
a 3,500 sq.ft. restaurant, 1,500 sq.ft. office, 1,338sidewalk. 11,591 sq.ft. driveway and parking and 3500 sq.ft
of future impervious surfacev(total 21,429 sq.ft.) on a 0.87-acre parcel. Located at 219 US Highway 70,
Havelock, Craven County, North Carolina the parcel accesses the service road of US Highway 70
approximately one and a half miles north of Highway 101. Less than one acre will be disturbed. As seen on
the included location and topo map, the ditch and the site drains to an unclassified existing ditch, then over
one and a half miles to Wolf Pit Branch and to Slocum Creek, a tributary of the Neuse River, classified as a
SC, SW and NSW water. This is a modification to an approved stormwater permit, No. SW7090905. The
permit modification includes reduction of impervious surface areas and replacing sand filter system with wet
pond and forebay.
EXISTING CONDITIONS
The existing topography of the parcel is a single drainage divide, which drains into an existing ditch along the
easterly boundary of the site. Per the included County Soils map, the soils are of the Ra, or Rains series. Per
boring at location as shown on the soils report map, the seasonal height water table (SH WT) is 24 inches
below existing grade, or elevation 22-feet.
STORMWATER MANAGEMENT
The project is located in Craven County (coastal) and was permitted under the high density option. The
revised plan now includes only 56% the total area of 38,202 sq.ft. of proposed impervious surfaces. In
V v
general, the design maintains the existing drainage pattern, with all impervious surfaces sheet flowing to into
forebays and into the main pool of the wet pond. As a function of 56% impervious surface and the Surface
Area to Drainage Area chart (Coastal Region-90TSS), the dimensions of the pond have been based on a
average depth of 3.0 and SA:DA ratio of 6_5. The areas (at corresponding elevations) in all calculations are
actual values. As seen in the attached calcu ations, the temporary volume was sized to control and treat run-
off generated by one and one-half inches of rainfall. The temporary volume (and greater events) store and
discharge through a 1.25 inch diameter orifice and 2.25' by 0.7' rectangular weir on the side (vertical) of the
concrete riser into a culvert and into an existing ditch. One foot of freeboard is provided.
The draw down for the post development 1 year, 24 hour is 48 hours, or 2 days, reaching a maximum
elevation of 22_65 feet. The 1-yr, 24 hour (3.9in.) post -development discharge rate from the wet pond through
the two orifices is 0.44 cfs. This is less than the 1-yr, 24 hour pre -development discharge rate of 1.47 cfs

The 10-yr, 24 hour (6.69in.) post -development discharge rate from the wet pond through the two orifices (10
year event does not reach weir at top of riser) is 3.22 efs., reaching a maximum elevation of 23.08 feet. This is
less than the 10-yr, 24 hour pre -development discharge rate of 4.09 cfs.
The draw down for the storage volume is 48 hours, or 2 days, reaching a maximum elevation of 22.78 feet

CONCLUSION
The proposed design is for 0.87 total acre site for a new commercial restaurant, office, parking and driveway.
56% of the site includes the proposed impervious surfaces, building and parking, and future impervious
surfaces which sheet flow to the farebays, wet pond, riser and existing ditch. The proposed project meets or
exceeds all DENR high density requirements.
