Dear Mr. Stephens:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Lakes @ Magnolia Greens on May 11, 2005. 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 000220

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

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,

Re: Stormwater Plan
Phase VI/The Lakes
5W8 000220 MOD
To Whom It May Concern:
Cape Fear Engineering, under the direction of Landmark Developers, is herewith submitting a permit
application to modify permit # 5W8 000220. With this application, the only change from the last
permitted revision (dated October 12, 2004) is the addition of one single-family parcel, lot #G-2G.
To facilitate the inclusion of this parcel under the active permit, we are providing:
• 1 Check for the permit fee of $420.00
• 2 Copies of the Stormwater Permit Application for Phase VI / The Lakes (I original)
• 2 Copies of the Wet Detention Basin Supplement (I original)
• 2 Copies of the Low Density Supplement for Phase VI / The Lakes (I original)
• 2 Copies of the Sample Stormwater Deed Restrictions for this application
• 2 Copies of the Design Narrative � Calculations
0 2 Copies of sheet 5WEC- I revised to show lot # G-2G
• 2 Copies of sheet 5WEC-2 (no revisions were necessary for this application)
As lot # G-2G shall be under the same Built Upon Area (BUA) restrictions as lots # G- I through G-25. all
permit paperwork has been revised to show the addition of this impervious surface draining to the on -site,
non -discharge lake.
This additional area yields a net increase in impervious surface from 27.35% to 27.40% in regards to the
complete project's drainage area of 170.15 acres. This change is seen as:
Total acres of impervious previously permitted = 4G.54
Total acreage of impervious currently submitted = 4G.G3
With such a minimal increase in impervious area, no changes to the permitted Stormwater BMP are
reQuired; however, appropriately completed permit documents are enclosed.
With this stated revision and the documents enclosed, I believe that all Stormwater concerns have been
addressed. Please let me know if you recluire any further information in regards to this Stormwater permit
application.
Sincerely, d�

DESIGN NARRATIVE
1. GENERAL:
The project site is located within the Magnolia Greens Plantation which is situated along the
northeast right-of-way on NC Hwy 17 approximately 1000 feet northeast from the intersection of
Hwy 17 and Lanvale Road, within Brunswick County, North Carolina. The site is located on the
east side of Grandiflora Drive between Pine Harvest Drive, Cornerstone Drive and golf holes 1
and 2 on the new golf course. The project area consists of approximately 170 acres within the
Magnolia Greens Plantation subdivision, all of which will be disturbed. Drainage considerations
are to be in accordance with DEM stormwater requirements.
The intent of this project is to develop single family housing. This project will also include the
installation of utilities and a stonnwater drainage system to a proposed non -discharge pond.
The single modification to the project for this submittal is one additional single-family homesite
within the development. This parcel is shown as lot # 6-26 on the enclosed plan and increases
impervious totals by the deed restricted 4,000 sf of Built Upon Area.
Accordingly, all previously permitted facets of permit # SW8 000220 are also included
2. EXISTING SITE:
Site topography in the area is relatively flat with slopes typically less than one (1) percent.
Vegetation consists primarily of grasses and minor ground cover within the area of the
improvements. Subsurface soils are typically a mixture of sands, silty sands and organics.
3. PROPOSED IMPROVEMENTS:
Improvements proposed include the construction of roads, utilities, and drainage considerations,
(see plans). Drainage considerations include the construction of a 13.8 acre non -discharge pond.
These improvements will support the proposed residential development.
4. DRAINAGE CONSIDERATIONS:
Drainage on the site will sheet flow to curb inlets within roadway areas. Proposed roads are to
be cut 1 to 1.5 feet below existing grade to insure that all lots will drain to the street. Stormwater

will then be collected in separate curb and gutter collection systems. From there, the drainage
will be piped to the proposed non -discharge pond at multiple locations, each ending in a flared
end section with rip rap. The proposed non -discharge pond will have a depth of approximately
four feet and is designed to retain a twenty-five year storm event with no discharge.
In addition to the non -discharge pond being able to contain an eight -inch rainfall event, a
stormwater pump station will also drain down the pond to provide golf course irrigation needs.
Irrigation water pumped from this pond will be aggressively filtered to prevent suspended solids
from clogging the tiny nozzles of the irrigation spray heads.
The pond surface elevation was determined to be twenty-one feet during the wet season.
Utilizing the Simple Method, the attached pond calculations demonstrate that there is ample
storage for an eight -inch rainfall event within this non -discharge pond.
5. EROSION CONTROL CONSIDERATIONS:
The proposed non -discharge pond will provide adequate sediment storage for the installation of
the proposed collection system. Inlet protection is to be installed once the inlets of the drainage
piping system have been constructed to reduce the amount of sediment released into the non -
discharge pond.
Erosion Control Measures and Sequence:
a. Temporary construction entrance.
b. Temporary sediment basins (non -discharge pond).
c. Energy dissipaters at the pipes into the non -discharge pond.
d. Temporary inlet sediment protection at storm drain inlets.
e. Temporary seeding should construction be halted for the specified time limit (refer to
specifications)
f. Remove all temporary erosion control measures once installation of utilities and paving
have been completed and a good vegetative ground cover has been established.
6. MAINTENANCE CONSIDERATIONS:
During construction, the Contractor shall be required to inspect and repair as needed all erosion
control devices after any significant rain event. Any measure found not performing its intended
function should be repaired immediately. Upon completion of construction and establishment of
permanent ground cover, the Owner shall be responsible for maintenance on the project site.
