Dear Mr. Lantz:
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for Scott
Street Parking Lot on May 10, 2011. Staff review of the plans and specifications has determined that the
project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 21-1.1000
and Session Law 2006-246. We are forwarding Permit No. SW6110501, dated May 17, 2011, for the
construction, operation and maintenance of the,subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until May 10, 2021, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for inspection 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 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC
27611-7447. Unless such demands are made this permit shall be final and binding.
This project will be kept on file at the Fayetteville:Regional Office. If you have any questions, or need
additional information concerning this matter; please contact Brian Lowther at [phone]; or
[e-mail].
Sincerely,
for Coleen H.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater will be treated by a wet detention basin located on the eastern side of the proposed parking lot.
Runoff will be conveyed via sheet flow off the parking lot into vegetated swales. A storm pipe network will
capture this runoff and route it to the proposed wet detention basin.
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 Cape Fear River basin.
4. Total Property Area: 11.62 acres
5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area+:11.62 acres
Total project area shall be calculated to exclude the followingg the noruml t7ool of impounded structures, the area
between the banks of stremns and rivers, the area below the Nornal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landeoard from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal ¢oetlmids landward of the NHW (or MHW) line any
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 60.1 %
9. How many drainage areas does the project have?3 (For high density, count 1 for each proposed engineered
stornuoater BMP. For late density and other projects, use 1 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

Wet Detention 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.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.,
This system (check one): RO
❑ does ® does not incorporate a vegetated filter at the outlet. JUN1�/��201,
This system (check one): ®�/j" /Q
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month 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 should be kept in a known set
location and must be available upon request. '
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
