Dear Mr. Worsley:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Rocky Point Scotchman- Hwy 210 on January 6, 2006. 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 2H.1000. We are forwarding Permit No.

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.
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,

Rhonda,
Below is the information you requested in your email dated December 30, 2005 concerning the Proposed
Scotchman Store on Hwy. 210 in Rocky Point.
1. The forebay volume will be at 20% (8537 C.F.) of the permanent pool volume.
2. In reference to Item #2, the 6.91 acres = 1.50 acres of on -site parking + 5.41 acres of on -site other as shown
page 2 of 4 in the application.
I am sending to you today a revised stormwater plan and revised wet detention basin supplement page 1 of 4 to
show corrections to the forebay calculations. I will also fax you a blow-up of the revised pond forebay size and
the revised wet detention basin supplement page 1 of 4.
Hopefully, this will help you in your continued review of the Stormwater Management Permit Application. Please
contact me if you have any further questions.

Scott,
Please provide the following information so that 2 can continue my review of the
Stormwater Management Permit Application for Worsley Companies' Proposed Scotchman
Store, Hwy 210:
1. Please ensure that the required forebay volume is being met. The forebay
volume should be between 18 and 22 percent of the permanent pool volume.
2. The hydraulic calculations indicate that 6.91 acres of impervious area are
being proposed for future development. However, the application indicates
that 5.41 acres of impervious area are being proposed for future development.
Please explain this difference.

DESIGN NARRATIVE
L GENERAL:
The project site is located near the west acceleration ramp to Interstate 40 and N.C. Highway 210
within Rocky Point in Pender County, North Carolina. The proposed development is a
commercial submittal with a project boundary of approximately 10.0 acres. It is a proposed
commercial development with a stormwater collection system and an on -site wet detention pond.
Drainage considerations are to be in accordance with state and county stormwater requirements.
2. EXISTING SITE:
The site currently is vacant. There is an existing gravel road on the west side of the property
within a 30 feet access easement. Site topography is relatively flat with a gentle slope from the
project's west boundary towards the east.
Vegetation consists primarily of minor ground cover. Subsurface soils are Meggett loam as
mapped in the USDA / SCS Soil Survey of Pender County, NC. The Engineering Data provided
therein show infiltration rates for the subject sands at a depth of approximately four feet:
Meggett >2 in/hr
3. PROPOSED IMPROVEMENTS:
Improvements proposed include the construction of a 4631 s.f. Convenience Store, a Gasoline
and Diesel Canopy and associated asphalt parking and a stormwater wet detention basin with
collection boxes and pipes. The site will be graded to divert all stormwater runoff from all
impervious surfaces to the proposed catch basins and detention area.
4. DRAINAGE CALCULATION CONSIDERATIONS:
Attached to this design narrative are the drainage calculations determining the amount of storm
water to be contained and treated in the stormwater system. The proposed wet detention design
should treat ail runoff from the first inch of rainfall to 90% efficiency.
5. MAINTENANCE CONSIDERATIONS:
During construction, the Contractor shall be required to inspect and repair as needed all erosion
and stormwater control devices after any significant rain event. Any measure found not
performing its intended function, shall be repaired immediately. Upon completion of
construction the establishment of permanent ground cover will be a priority.
