Dear Dr. McKeithan:
The Wilmington Regional Office received a complete modification to the Stormwater
Management Permit Application for Cape Fear Community College -North Campus on
December 11, 2003. 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. SW8 990923 dated December 12,
2003, for the construction of Cape Fear Community College -North Campus.
This permit shall be effective from the date of issuance until January 28, 2010, (10
years from the original issue date) 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.
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

Mark:
Can you also send me a breakdown of the impervious areas, in square
feet, for the engineering building? Email is fine. Thanks,
Linda

I am not sure I completely understand your request regarding the
surface area of the pond. I looked at the September 1, 1999,
calculations, and apparently there is an error in the SA/DA ratio
you used. My spreadsheet came up with 4.5%, or 82,132 sq. ft. as a
minimum pond area. Somehow, you came up within an SA/DA of 4.76%
but only 78,482 sq. ft. When I multiply 41.9 acres by 4.76%, I get
86,878 sq ft as the minimum surface area. I guess since you were
proposing to provide 82,208 sq. ft of area, which exceeded our
calculated Minimum, Scott Vinson did not make you aware of your
calculation error.
I have to leave the permitted amount provided at 82,208 sq. ft., or
you will be..short. Please verify that this minimum is provided in
Pond #3.

Re: Update to NCDWQ Project No. SW8 990923
Cape Fear Community College - North Campus
New Hanover County
WKD #10706.00.WL
Dear Ms. Lewis:
The enclosed proposed plans are for the second building at the North Campus of the Cape
Fear Community College. 'All of the runoff from impervious areas of this project wilt be
directed to the existing detention pond No. 3. Please find enclosed 2 sets of plan sheets
C1.1, C4.1 and C5.1 along with an original and one copy of the revised built upon area
calculation sheet for your review and records.
Also please note that in reviewing the previously approved calculations and permit, I
found a discrepancy in the surface area calculations for Pond No. 3. The calculations,
dated September 1, 1999, show a minimum required surface area of 78,483 SF. The
design plans provide 78,605 SF at normal pool. The permitted surface area is actually
different from what we had on the plans and in the calculations. The current permit shows
821208 SF. Based on these previously submitted plans, we request that you modify this
number on the permit to reflect 78,605 sf.
Please call if you have questions or need additional information.
Sincerely,
W. K. DICKSON & CO., INC.
