Maintenance activities shall be performed as follows:
1. 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,now
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

«A» INFORMATION PERTAINING TO DEED RESTRICTIONS
AND PROTECTIVE COVENANTS
In accordance with Title 15 NCAC 2H.1000, the Coastal Stormwater Management
Regulations, deed restrictions and protective covenants are required for High Density
Commercial Subdivisions where lots will be subdivided and sold. Deed restrictions and
protective covenants are necessary to ensure that the development maintains a "built-upon"
area consistent with the design criteria used to size the stormwater control facility. The
following deed restrictions and covenants must be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State
Stormwater Management Permit Number , as issued by the Division
of Water Quality under NCAC 2H.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent
necessary to maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties
claiming under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the
express written consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without
the concurrence of the Division of Water Quality.
6. The maximum allowable built-upon area per lot is as follows:
Lot# BUA Lot# BUA Lot# BUA
Out-Parcel A, 33,715sf Out-Parcel B, 19,994sf Home Depot, 397.136sf
These allotted amounts include any built-upon area constructed within the lot property
boundaries, and that portion of the right-of-way between the front lot line and the edge
of the pavement. Built upon area includes, but is not limited to, structures, asphalt,
concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include
raised, open wood decking, or the water surface of swimming pools.
7. All runoff from the built-upon areas on the lot must drain into the permitted system. This
may be accomplished through a variety of means including: a piped collection system,
which ultimately discharges into the stormwater facility; appropriate grading of the lot
such that the built-upon surfaces drain into the stormwater facility; or graded swales
which collect runoff and direct it into the stormwater facility.
8. Each lot whose ownership is not retained by the permittee, is required to submit a
separate stormwater permit application to the Division of Water Quality and receive a
permit prior to construction.

MYRTLE GROVE VILLAGE
NEW HANOVER, NORTH CAROLINA
Project#06130.PE
DESIGN NARRATIVE
Port City Central LTD. Partnership is proposing to redevelop the old Myrtle Grove Wal-mart
shopping center located near the intersection of U.S. 421 &Piner Rd.for a Home Depot site and
additional commercial/retail development. The parcel to be developed is 52.2 acres (Deed
Book:4912,Page: 1420) and is located in New Hanover County's jurisdiction.
The existing site consists of approximately 12 acres of fairly wooded cover on moderately
sloped terrain with the remainder as predominately impervious cover as a result of the
parking/buildings from the previous shopping center. The stormwater management system
for the previous development was permitted by the State under permit#SW8 060740.
The existing soils on the site are comprised of Leon (Le), Lynn Haven (Ly), Kureb (Kr), and
Murville (Mu) according to the Soil Survey of New Hanover County; data from New Hanover
County G.I.S. The project is within a drainage basin that drains to an unnamed tributary of
Motts Creek (C; SW, 1.0" runoff). All stormwater will be conveyed through a storm drainage
system into two wet detention ponds. Both ponds currently serve the existing shopping center
and will be reconstructed to accommodate for the proposed development.
PROPOSED IMPROVEMENTS/ STORMWATER
The Developer completed a Traffic Impact Analysis as required by New Hanover County and
NCDOT. The analysis concluded that various off-site mitigation to the roadways and traffic
signal system was required. The added impervious surface due to new asphalt area is 16,319sf.
1.) Piner Road (SR-1521) is required to have additional through and turn lanes added to
meet future traffic demands. We are proposing to leave the roadside swales to the
north of the roadway undisturbed. The proposed widening is all to the south of the
existing roadway, therefore; holding the northern existing edge of pavement. The
south side of the roadway will widen and include curb and gutter with curb inlets to
capture stormwater runoff. Once captured, the stormwater runoff will be conveyed
through an existing closed conduit system which eventually enters a tributary to Motts
Creek.
2.) US Hwy 421 is required to add an additional left turn lane at the Monkey Junction
intersection. The addition of a left turn lane to the north will create additional
pavement to the south side of the intersection. This portion of roadway is currently

being treated by a roadside swale which then discharges to a drop inlet. We are
proposing to continue using the existing roadside swale as our BMP for the new asphalt
area.
CONSTRAINTS FOR NOT MEETING BEST MANAGEMENT
PRACTICES:
The attached calculations for the existing roadside swales show that adequate capacity is
available and maximum velocity is not exceeded, to treat the existing and proposed impervious
runoff. The proposed curb section with curb inlets will not be treated by a BMP. We explored
using the existing wet detention basin located along Piner Road as a BMP. However, if the
stormwater runoff was added to that facility, we would exceed the minimum surface area
requirement by approximately 3-5%.
All design calculations can be found in the following pages of this report.
