Dear Mr. Merritt:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Village at Cypress Bay on May 22, 2008. Staff review of the plans and

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 sixty (60) days
following receipt of this permit. This request must be in the form of a written petition,

area limit is transferred to the individual property owner.
3. If an Architectural Review Board or Committee is required to review plans for
compliance with the BUA limit, the plans reviewed must include all proposed

LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
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, DWQ BMP Manual (2007), and Session Law 2006-246.

Re: Storm-water Project No. SW8 070232 Modification
The Village at Cypress Bay I
Brunswick County
Dear Ms. Hall,
We are submitting the attached revised site plans and calculations, to address
and correct errors in the previously approved storm-water permits and issues
created by NCDOT's improvements to Goodland Road. NCDOT has replaced all
the existing storm-water drainage pipes along Goodland Road, in doing so the
have raised the elevation of the pipe that our site drains to. This has caused us to
change the elevations of our storm water pond, (normal pool, temporary pool,
orifice and outlet structure elevations). These minor changes were caused by
circumstances outside of our control, therefore all modifications were done using
the requirements that were in place at the time of the previous submittal.
If you have any questions concerning this matter please contact me at (910)
383.1044 ext. 119 or email me at mike.tackett@capefearengineering.com.
Sincerely,
Michael Tackett,
P.L.S.

DESIGN NARRATIVE
General:
The project site is located Snowfield Road (SR#1522) off of US Highway 17 within Brunswick
County, North Carolina. The project area to be disturbed is approximately 1.45 acres. Drainage
considerations are to be in accordance with DWQ storm water requirements. This submittal is for
revisions to the approved Storm Water Permit SW8 070232.
Existing Site:
Site topography in the area is relatively flat for the most part with some slopes typically less than
three (3) percent. Vegetation consists primarily of grasses and minor ground cover. Subsurface
soils are typically a mixture of sands, silty sands and organics.
Proposed Improvements:
Improvements proposed include drainage devices, streets, and utilities. Drainage for the most
part will sheet flow from the lots into the streets which will have curb and gutter to direct
drainage to low points in the roads. Drainage from the low points will drain into a stormwater
pond. The pond will drain to surrounding wetlands.
