Dear Mr. Harrison:
The Washington Regional Office received a complete Stormwater Management Permit Application for the
proposed RHG Office Building to be located at 700 Blue Jay Street, Kill Devil Hills, NC on January 7, 2011.
Staff review of the plans and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Session Law 2008-21land Title 15A NCAC 21-1.1000. We are forwarding
Permit No. SW7101102 dated January 31, 2011, for the construction of the subject project.
This permit shall be effective from the date of issuance until January 31, 2021, and shall be subject to the
conditions and limitations as specked therein. Please pay special attention to the Operation and Maintenance
requirements in this permit. Failure to establish an adequate system for operation and maintenance of the
stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150E of the North Carolina

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization';'
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of Nl1V 2���
approximately six inches.
F ,
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration Basin Inspection, Operation and Maintenance Agreement
In addition to the standard inspection and operation procedures set
out on pages 1 and 2 of this agreement, the infiltration basin and
forebay shall be inspected once a quarter and after every storm event
greater than 1.5 inches.by access through access wells at the northern
facade of the building and at the southern end of the western facade
of the building at the overflow weir by removing the drop -in wooden
grate beams.
Inspection shall be visual with the aid of hand-held lighting and a
tape measure. Constructed, unsilted basin bottom elevation is 2' 7-
112" below the bottom of the floor joist underpinning, which is the
target bottom elevation upon completion of construction and when
cleaning out siltation.
The forebay condition shall be inspected by measuring locations of
apparent highest elevation on the surface of the siltation in four
approximately equal quadrants. If siltation in any measurement
quadrant exceeds an elevation of 2' 4" below the floor joist
underpinning, siltation shall be removed from the forebay to the
target elevation. Removal shall be by raking the silt with a concrete
rake into the access well, and then removing and properly disposing of
the material from the access well . Upon completion of silt removal,
the bottom of the forebay shall be in a smooth and level condition.
The main basin shall be inspected by measuring locations of apparent
highest elevation in piling bays. If average siltation exceeds an
elevation of 2' 4" below the floor joist underpinning, siltation shall
be removed from the basin to the target elevation. Removal shall be
by raking the silt with a concrete rake into the access wells, and
then removing and properly disposing of the material from the access
wells. Upon completion of silt removal, the bottom of the basin shall
be in a smooth and level condition.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater runoff from impermeabe surfaces is conveyed to an infiltration basin under the pile supported
principle building. The basin has approximately 2 5 times the required capacity, does not discharge a 10 year
24-hour storm, and has an overflow to the Town of Kill Devil Hills street swale and drainage system
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW -1995 ❑ Ph II - Post Construction
3. Stormwater runoff from this project drains to the Atlantic Ocean River basin.
4. Total Property Area: 0.486 acres
5. Total Coastal Wetlands Area: 0.0 acres
6. Total Surface Water Area: 0.0 acres
7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area.(6) = Total Project
Area': 0.486 acres
Total project area shall be calculated to exclude the following the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
W) (MHline, and coastal wetlands landward from the NHW (or MHI) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (orMHW) line nmy
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 64.89 %
9. How many drainage areas does the project have? 1 (For high density, count 1 for each proposed engineered
stormwater BMP. For low density and other projects, use I for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Completion Certification,
Dear Roger:
Please note that this, letter certifies construction completion
effective January 18, 2012 (apparently no final Certification was
submitted to your office at that time).
Construction of the referenced project was complete within substantial
compliance and intent of the approved plans and specifications, with
the following incidental adjustments:
1. A concrete crown similar to the original design crown depicted on
the drawings has been installed at the top of the driveway slope
at the western parking area to intercept and convey stormwater to
the drop inlet within the western parking area.
2. The southern 2 feet of the curb, gutter and pavement of the newly
installed eastern drive apron was cut and removed to meet the
design configuration, and the adjacent roadway shoulder was
lowered to create a shoulder swale.
3. Sod has been substituted for rip -rap depicted on the drawings at
driveway apron low -velocity flume discharges.
Please e-mail me at [e-mail] or call me at (252)
