Dear Mr. McCullough:
The Washington Regional Office received a completed Stormwater Application for the subject project on July
11, 2007. Staff review of the plans and specifications has determined that the project, as proposed, will comply with
the Stormwater Regulations set forth in Tide 15A NCAC 2H.1000. We are forwarding Permit No. SW7061230 dated
October 31, 2007 to Patrick McCullough for four interconnected wet detention ponds to serve the Craeberne Forest —
A Planned Unit Development located at the end of Trent Creek Road in New Bern, North Carolina.
This permit shall be effective from the date of issuance until October 31, 2017, shall void Permit No.
SW7060612 dated February 1, 2007 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 operation and maintenance of the stormwater management system will result in future compliance
problems. The issuance of this permit does not resolve any previous violations of the stormwater rules for
construction without a permit.
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 General Statutes,
and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. Unless such
demands are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact Samir
Dumpor or me at [phone].

I When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3.2 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.2 feet in the forebay, the sediment shall be removed.

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
DEC 2 12006
LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original DWQ-WAR®
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be
found in 15A NCAC 2H .1005 through .1007.
I. PROJECT INFORMATION
Project Name : Craeberne Forest Subdivision
Contact Person: Joseph C. Avolis, P.E. Phone Number: ( 252 ) 633-0068
Number of Lots: —0—
Allowable Built Upon Area Per Lot*:=0—
*If lot sizes are not uniform, attach a table indicating the number of lots, lot sizes and allowable built upon area
for each lot. The attachment must include the project name, phase, page numbers and provide area subtotals
and totals.
11. BUILT UPON AREA
See the Stormwater Management Permit Application for specific language that must be recorded in the deed
restrictions for all subdivisions.
For uniform lot sizes, complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water. Wetlands may be excluded when the
development results in high density pockets.
• DF Density Factor - the appropriate percent built upon area divided by 100.
• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. Lots - the total number of lots in the subdivision.
• BUA/Lot - the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.

Calculation:
Project is for land clearing of roadways and future detention pond areas
only. Work does not involve any impervious surfaces at this time. A
future permit will be submitted to cover future development. This initial
permit would allow the work to progress while the design elevations
and utilities are being developed.
