Dear Mr. Tillman:
-wo(A'U
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SV 7970115 for a stormwater treatment system consisting of two
wet detention ponds serving Hatteras Island Plaza, Phase 2 located at 41934 NC 12 at
Kinnakeet Shores, Avon, NC expires on March 23, 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. Permit application forms for renewal can be found on our website at:
https://deq nc gov/about/divisions/energy-minerzil-land-resources/enerav-mineral-l�ind-
rules/stornitvater-program/post-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
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 form. You can request a copy by e-mailing me at roger.thorpe(a)ncdenr.gov.

Good Afternoon,
✓ �(�. 2-

I just spoke with Scott Vinson with the North Carolina Department of Environmental Resources (252-948-3844)
regarding removing the downspouts that feed directly into the storm sewer system. Scott looked up the permit
(SW7970115) that belongs to the shopping center and saw 3 drop inlets located at the back of the store, I was able to
confirm this by pictures. He said that so long as the water was being sent to the nearby pond he would not have a
problem with us surface draining the roof.
After a conversation with Gordon, we will not proceed with this change until further notice.
If anyone has any questions, please feel free to contact me.

CORRECTIVE ACTION PLAN regarding HATTERAS ISLAND PLAZA
STORMWATER VIOLATION issued March 13, 2007
On behalf of O.T. Enterprises, LLC., BPG submits for your review the proposed corrective action
plan for the maintenance of the existing drainage infrastructure servicing the Hatteras Island Plaza
commercial site located in Avon, Dare County, NC.
As per your suggestions in recent telephone conversations we have had regarding the current
violation, our client, Mr. Brantley Tillman of O.T. Enterprises, LLC, is in the process of addressing
the items as described in the Notice of Violation issued March 13, 2007.
Corrective measures will be as follows:
Obtaining a 15' wide maintenance easement around the perimeter of Pond #1 with an
associative access easement (wet detention ponds shown in the Stormwater Management Site
Plan)., Pond #1 has approximately 3.705 acres of surface area and approximately 2.436 acres
of the pond is located on the adjoining property to the west that is currently owned by Outer
Banks/Ktnnakeet Associates, LLC.
Obtaining a 15' wide maintenance casement around the perimeter of Pond #2 with in
associative access casement. Pond #2 has approximately 0.154 acres of surface area with
approximately 0.144 acres of the pond located on the adjoining property to the south that is
currently owned by ADARE, Inc. The remaining +- 0.010 acres of Pond #2 reside on
adjoining property owned by Outer Banks/Kinnakeet Associates, LLC.
The intent is of this plan is to provide corrective action on the existing Stormwater basins to
ensure continued operation and maintenance of the overall drainage network that currently
serves the existing Hatteras Island Plaza Commercial development. These corrective action
items include, but are not limited to, identifying all existing trees located along the eastern
periphery of the existing basins, in excess of a six inch base diameter or those trees observed
to be leaning over the water surface and prohibiting proper function of the basin. Areas of
excessive sediment accumulation at the various basin inlet points will also be identified for
removal.
It is intended that this process will be completed 30 days from the date of signature of this
document with an additional 60 clay allowance for implementation of the identified corrective
action measures. All identified corrective action measures will be coordinated with the
engineer/ and or engineer's representative responsible for certification of the system.

Dear Mr. Keith:
The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW7970115

requires that applications for permit renewals shall be submitted 180 days prior to the expiration of a
permit and must be accompanied by a processing fee, which is currently set at $420.00. If this is still an
active project please complete and submit the enclosed renewal application in a timely manner. If this
project has not been constructed and a permit is no longer needed, please submit a request to have the
permit rescinded. If you have sold the project, or are no longer the permittee, please provide the name,

~ ' Stormwater Management Permit Modification Narrative:
All but two previous developmental activities have been permitted under NCDEHNR permit no.
SW7950808 dated December 27, 1995, and permit no. SW7970115 dated April 10, 1997, and
complied with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. The intent of this
permit modification is to retain best management practices for all previous permitted and non -
permitted developmental activities. The 9.467 ac. subject property is located on the west side of NC
State Route 12 approximately 700 feet south of the roadway intersection of Kinnakeet Boulevard and
NC 12, in Avon Township of Dare County, North Carolina.
The most recent developmental activities that have been completed but were not included in the
previous permit, designated as Phases H-E and II-F, consist of (2) retail commercial buildings with a
total of 4,968 sq.ft. within the existing development plaza. These additional buildings were completed
in 1999. No additional drainage systems, nor parking or access areas were created. Subsequently, the
site was subdivided and the 3.5 ac. Parcel III -A was conveyed (2000), after which the remainder of the
site (9.467 ac.) was twice conveyed, with the final conveyance to O.T. Enterprises, LLC. on
12-01-2004.

The site's developed topography is relatively flat with gentle slopes ranging between 0-1 %. Eastern
portions of the site near NC 12 slope towards existing catch basins, with Drainage Area #1 draining to
Pond #1, and Drainage Area #2 draining to Pond #2. Western portions of the impervious areas slope
to adjoining "404" Jurisdictional wetlands to the west that also drain to Pond #1. The Ponds #1 and
#2 do not contain drainage outlets, but are hydraulically linked through a thin strip of wetlands to the
21.2 ac. lake as shown on STORMWATER MANAGEMENT SITE PLAN. There are approximately
0.352 acres of "404" Jurisdictional wetlands currently existing on -site. The receiving Pamlico Sound
has a classification of "SA".
All developmental activities were designed in conformity with the requirements for application and
issuance of pennits for stonnwater management systems in pursuant with rules .1003 and .1005 in
accordance with G.S. 143-215.1 and 15A NCAC 2H .0200 as set forth. These requirements are
designed to control pollutants associated with somrwater runoff applicable to development of land for
residential, commercial, industrial, or institutional uses. The developmental activities described herein
were designed in compliance with the requirements as set forth for stonnwater management within
coastal counties Rule .1005, section 3, subparagraph 13:
(i) Control systems must be infiltration systems, wet retention ponds, or alternative stonnwater
management control systems designed in accordance with Rule .1008;
(ii) Control systems must be designed to control runoff over the entire drainage area generated by
1.5 inches of rainfall.

Design of the active stormwater management measures are based on the design criteria indicated in
.1008(e) Wet Detention Pond Requirements, under the NCDENR Division of Water Quality
Administrative Code for Stormwater Management, 15A NCAC 2H.1000.
The site had been previously permitted with (1) drainage area. An As -Built survey of the site
conducted in 2003 (details included within the site plan) indicated a stormwater conveyance and
detention system that was not indicated in the two previous stormwater permits. The limits and
impermeable areas of this second watershed (delineated as Drainage Area #2 in the site plan) appear to
have been included within the previously permitted drainage area, permit no. SW7970115 (1997).
The Drainage Area #2 watershed appears to have been constructed with Phase H-D. (Please
reference Stonnwater Management Site Plan for Drainage Area Delineations). The most recent
developmental activities consisted of the construction of (2) commercial buildings (Phases II-E and lI-
F) totaling 4,968 sq.ft. without any additional parking, access drives, or drainage systems. The newer
buildings add to the rainfall runoff within Drainage Area #1 only.
Drainage Area #1
This drainage watershed encompasses nearly 93% of the entire developments impervious coverage,
including all existing buildings and 90% of the parking, drives and walk ways. The previously
permitted (4-11-97) total impervious coverage was 312,771 s.f. (7.18 ac.). With this application's
Drainage Area 41 delineation, the impervious coverage of this watershed was 286,062 sq.ft. (6.567
ac.) before the additions of Phases fl-E and 11-F. With the addition of the two commercial buildings
within Drainage Area #1, the impervious coverage was increased to 290,979 sq.ft. (6.680 ac.), an
increase of nearly 1.72% . Compared to the total impermeable surface area indicated in the permit,
this is an increase of 0.16%.
The associative runoff continues to have a control system in the form of an existing pond (designated
as Pond #1) that has been serving as a forebay to an adjacent 21.2 acre lake. Rainfall runoff from all
existing buildings and 90% of the parking & drive surfaces are collected and directed by curb & gutter
to various curb inlets connected to a network of drainage pipes that ultimately discharge to Pond #1
located along the project's western boundary. Within the middle eastern portion of the parking area,
flow is collected in an existing adjoining vegetative swale that outlets to the pipe network via a drop
inlet located near the right of way of NC 12. The rooftop runoff from the buildings is collected by a
perimeter gutter system that discharge to the adjacent pavement to the west of the buildings. Rip -rap
inlet protection is in place at the pond's wetland area inlets for velocity dissipation and to aid in
infiltration and sediment removal. The pond does not contain a drainage outlet, but is hydraulically
connected through a thin strip of wetlands to the 21.2 acre lake as shown on the site plan. The
hydraulic linking provides water level control in Pond #1 and prevents sediments and pollutants from
reaching the lake, allowing the pond to act passively as a large forebay to the lake. Pond #1 has the
physical attributes required to remove 90% of total suspended solids from the associative design storm
runoff of 1.5 inches rain. The pond has the detention capacity to contain the initial 4.51 inches of
storm runoff, assuming no infiltration and including the rain that falls within the pond's shoreline. The
pond has a detention capacity factor of 4.75 of the required volume for a 1.5 inch rain event. Pond #1
and conveyances for Drainage Area # 1 do not have drainage easements associated with them.
Drainage Area #2
As indicated above, Drainage Area #2 was not defined in the last issued permit, but available records
indicate that the conveyance system of Drainage Area #2 was constructed with Phase 11-D. Rainfall
runoff from the parking & drive surfaces sheet flow over the parking areas and are collected and
directed by curb & gutter to one curb inlet connected to an existing 18" RCP stormwater conveyance
that is discharged to Pond #2 located approximately 133 ft. south of the site's south boundary. Part of

the conveyance and Pond #2 are on an adjoining property (Parcel III -A). Parcel III -A had been a part
of the site in the last permit, but was conveyed in 2000. The conveyance was given a drainage
easement, but no drainage easement exists for Pond #2.
Rip -rap inlet protection is in place at the pond's wetland area inlet for velocity dissipation and to aid in
infiltration and sediment removal. The pond does not contain a drainage outlet, but again, is
hydraulically connected through a thin strip of wetlands to the 21.2 acre lake as shown on the site plan.
The hydraulic linking provides water level control m Pond #2 and prevents sediments and pollutants
from reaching the lake, allowing the pond to act passively as a large forebay to the lake. Pond #2 has
the physical attributes required to remove 90% of total suspended solids from the associative design
storm runoff of 1.5 inches rain. The pond has the detention capacity to contain the initial 3.12 inches
of storm runoff, assuming no infiltration and including the rain that falls within the shoreline of pond
#2. The detention capacity of the pond has a factor of 2.74 of the required volume for a 1.5 inch rain
event. It should be noted that the additions of Phases II-E and H-F are not tributary to Drainage Area
#2
Based on the overall design of this development, stonnwater runoff from the existing impervious
surfaces receive treatment, to the maximum extent possible, in the form of existing ponds that act
passively as forebays to the large lake further to the west of the project. The intent of this existing
design was to provide adequate pollutant filtration measures to stormwater runoff resulting from the
high -density pocket created with this commercial center. Measures were designed to treat runoff from
the associated development in accordance with best management practices at the time of the last
stormwater management plan permit application (1997). Existing impervious surface areas were
utilized to compute the required storage volume from the associated 1.5 inch rainfall storm event,
(please reference Attachment A for stormwater management calculations). It is expected that the
existing system will continue to provide pollutant removal efficiency and provide sufficient protection
to the adjoining surface waters. It should be noted that the system of Drainage Area #1 has been
designed to retain and treat an excess of 4.75 times the required runoff associated with the design 1.5"
rainfall event.
Stormwater runoff from all impervious surfaces will receive a form of pollutant and sediment removal
as described in best management practices. The following information is in conformance with the
regulations as specified for high -density development:
I ) Provision of a wet detention basin for temporary stormwater storage for the
design storm event in conjunction with 90% pollutant removal.
2) Provision of a pipe conveyance network along the outer periphery of asphalt
drives & parking to collect and transport stormwater runoff from all impervious
surfaces.
