NARRATIVE
PROJECT DESCRIPTION;
The existing site is a 1.92 acre developed site within the Wilmington City limits, in New Hanover
County, North Carolina. The existing site is being redeveloped to include a new mixed use
building with office, retail and restaurant space. The existing site has existing access to Market
Street (US Hwy. 17) and Old Eastwood Road.
SITE DESCRIPTION AND INFORMATION:
As stated above, the existing site is developed and will be redeveloped to include a new mixed
use building with office, retail and restaurant space. Existing asphalt parking and access
currently exist on the site. An existing permitted stormwater pond also currently exists on the
site. Minor parking lot and access modifications will be required to accommodate the new
building. The building that was on the site was demolished several years ago. The existing site
is currently permitted under New Hanover County Grading Permit No, GP 26-96 Revision and
State Stormwater Permit No. SW8 960315 Modification. Copies of the above permits are
included with the permit submittals. The site is now within the Wilmington City limits. Therefore,
the new impervious area will be subject to the City of Wilmington Stormwater Ordinance. The
stormwater pond outlet structure will be modified to meet the City of Wilmington Stormwater
Ordinance. Additional stormwater pond modifications are proposed to meet the State
Stormwater regulations as described below.
As stated above, impervious area on the site consist of existing asphalt parking and access and
new impervious area defined as follows. New impervious area is the new building and existing
asphalt pavement and concrete which is being removed and replaced. As stated above, the
new impervious area is subject to the City of Wilmington Stormwater Ordinance. Overall, there
is a net decrease in total impervious area listed in State Stormwater Permit No. SW8 960315
Modification from 65,550 SF to 63,400 SF. See the site data table in the calculations and on
Sheet C4 of the plans for a detailed breakdown of impervious areas.
Grades on the existing site vary as shown on the plans. Approximately 2.86 acres is included in
the disturbed area 1 construction limits. A portion of the disturbed area / construction limits
include a new right turn lane and new sidewalks within the NC DOT right of way along Market
Street (US Hwy. 17). A portion of the disturbed area I construction limits also include the existing
driveway and new sidewalks within the City right of way along Old Eastwood Road. There are
no protected or significant trees on the existing site.
EROSION CONTROL MEASURES:
The attached plans and specifications give the requirements for erosion control measures. Silt
fence shall be installed on the site prior to grading as shown on the attached plans. The existing
stormwater pond will be used as a silt basin during construction and restored to the proposed
design contours prior to completion of construction. Erosion control measures shall be installed

around the drop inlets as shown on the plans to trap silt during construction. Inspect the erosion
control around the inlets after each rain to make repairs as needed. Remove sediment as
necessary to provide adequate storage volume for subsequent rains. When the contributing
drainage area has been adequately stabilized, remove all materials and any unsuitable soil and
either salvage or dispose of it properly. Bring the disturbed area to proper grade, then smooth
and compact it. Appropriately stabilize all bare areas around the drop inlets. A gravel
construction entrance will be provided as noted on the plans. Maintain the gravel construction
entrance in a condition to prevent mud or sediment from leaving the site.
STORMWATER MANAGEMENT MEASURES:
The project site is located in the Wilmington City limits in New Hanover County, North Carolina.
Land disturbing on the site will exceed one acre, which requires the site to comply with the State
Stormwater Regulations. In addition, a portion of the site will also have to comply with the City of
Wilmington Stormwater Ordinance. The existing stormwater pond will be restored and modified
to meet both the State and City of Wilmington design standards. This narrative will focus on the
aspects of the state design criteria. The existing stormwater detention pond is designed to
achieve 90% TSS removal. Critical design elevations are detailed on the plans and in the
calculations. The required storage volume will be released within the 2-5 day draw down period
as shown in the calculations. A forebay is provided at the head of the stormwater pond. When
the stormwater pond was originally approved, the forebay was not required to handle 20% of the
total pond volume. A 10' vegetative shelf was also not required when the stormwater pond was
originally approved under State Stormwater Permit No. SW8 960315 or SW8 960315
Modification. As stated above, the stormwater pond outlet structure will be modified to meet the
City of Wilmington Stormwater Ordinance. Other stormwater pond modifications will include re-
establishing the existing approved forebay and re-establishing the approved stormwater pond
depth and increasing the stormwater pond depth by 0.50' to meet the State surface area
requirement at normal pool. All stormwater runoff from impervious areas will be directed to the
stormwater pond.
CONSTRUCTION SEQUENCE:
The contractor will install the gravel construction entrance and silt fence prior to beginning any
grading operations. The existing stormwater pond will be used as silt basins during initial
grading phase. The stormwater pond will then be fine graded and restored to the proposed
contours shown on the plans and the outlet structures and piping will be installed with riprap
protection. Disturbed areas will be landscaped or seeded within 15 days of disturbance.

MAINTENANCE PLAN
1. All erosion and sediment control practices will be checked for stability and operation
following every runoff -producing rainfall but in no case less than once every week. Any
needed repairs will be made immediately to maintain all practices as designed.
2. Install erosion control measures before beginning construction or as soon thereafter as
possible. All erosion and sediment control practices will be checked for stability and
operation following every runoff -producing rainfall but in no case less than once every
week. Any needed repairs will be made immediately to maintain all practices as
designed.
3. Maintain the gravel construction entrances in a condition to prevent mud or sediment
from leaving the construction site. The contractor shall inspect the construction
entrances on a daily basis. This will require periodic top dressing with additional No. 4
stone. Any objectionable materials spilled, washed, or tracked onto public roadways
shall be removed immediately.
4. Install erosion control measures around the drop inlets as shown on the plans to trap
silt during construction. Inspect the erosion control around the inlets after each rain and
make repairs immediately. Remove sediment when it becomes 0.50 deep to provide
adequate storage volume for subsequent rains. When the contributing drainage area
has been adequately stabilized, remove all materials and any unstable soil and either
salvage or dispose of it properly. Bring the disturbed area to proper grade and
appropriately stabilize all bare areas around the drop inlets.
5. Sediment will be removed from behind the silt fence when it becomes 0.5 feet deep at
the fence. The sediment fence will be repaired as necessary to maintain a barrier.
6. No cut or fill slopes shall exceed a side slope of 1 vertical to 3 horizontal unless
otherwise specified on the plan. All slopes shall be seeded and stabilized within 15
days.
7. The stormwater ponds will act as sediment basins and will be cleaned out when the
level of sediment reaches 2.0 ft below the top of the riser. Gravel will be cleaned or
replaced when the sediment pool no longer drains properly.
8. No cut or fill slopes shall exceed a side slope of 1 vertical to 3 horizontal unless
otherwise specified on the plan. All slopes shall be seeded and stabilized within 15
days.
9. All disturbed areas shall be seeded within 15 days of disturbance. All seeded areas will
be fertilized, reseeded as necessary and mulched according to specifications in the
vegetative plan to maintain a vigorous, dense vegetative cover.

10. More stringent measures shall be used to halt erosion if those shown on this plan are
not effective.
11. All erosion shall be controlled including side slopes before the project is completed.
12. Remove temporary measures upon completion of project. All permanent measures will
be well established before project closeout.

POND MARUENANCE REQ S
PAGE 2
TV. Annually (Once a year)-.
A. The pond depth will be checked at various points. Sediment removal is required when the
depth is reduced to 75 % of the original design depth or T , whichever is greater. Design
depth is ', measured vertically from the orifice down to the pond's bottom.
Sediment must be removed to at least the original design depth.
V. General: a
A. Mowing of the side slopes will be accomplished according to the season. Maximum grass
height will be 6" .
B. Cattails are encouraged along the pond perimeter, however they will be removed when they
cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of
the growing season, in November. Environmentally sensitive chemicals for use in killing
cattails can also be used. Contact your nearest Agricultural Extension Agent.
C. The orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not
accomplished in that time, the orifice will be replaced with a Iarger or smaller orifice. Slow
drawdown may be attributed to a clogged system. The source of the clogging will be found
and eliminated.

height will be 6" .
B. Cattails are encouraged along the pond perimeter, however -they will be removed when they
cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of
the growing season, in November. Environmentally sensitive chemicals for use in killing
cattails can also be used. Contact your nearest Agricultural Extension Agent.
C. The orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not
accomplished in that time, the orifice will be replaced with a larger or smaller orifice. Slow
drawdown may be attributed to a clogged system. The source of the clogging will be found
and eliminated.
D. All components of the detention pond system will be kept in good working order. Repair
or replacement components will meet the original design specifications as per the approved
stormwater plan. If previously approved components are determined to be ineffective, the

action of air and ~cater. and suitable in all other respects for the pur-
pose intended. Where broken concrete from demolished structures or
pavement is available, it may be used in place of stone provided that
Such use mevts with the approval of the Engineer. However, the use
of broken concrete which contains reinforcing steel will not be
permitted.
The stc:,.e or broken concrete shall be graded to meet the Following
requirements:
1. For Class 1 Rip Rap. Stone shall vary in weight from 5 to 200
pounds. At least 30 percent of the total weight of the rip rap
shall he in individual pieces weighing a minimum of 60 pounds
e:,ch. Not more than 10 percent of the total weight of the rile rap
matt• he in individual pieces weighing less than 15 pounds each.
2. For Class 2 Rip Rap. Stone shall vary in weight from 25 to 250
pounds. At least 60 percent of the total weight of the rip rap
shall be in individual pieces weighing a minimum of 100 pounds
each. Not more than 5 percent of the total weight of the rip rap
may be in individual pieces weighing less than 50 pounds each.
942-2 S'ITONE FOR EROSION COIv'TROL.
The stone shall be of a hard, durable nature and shall range in size
as follows:
Class Size
A 2.- 6"
B V-15'
All stone shall meet the approval of the Engineer. while no specific
gradation is required, the various sizes of stone shall be equally dis-
tributed within the required size range. The size of an individual
stone particle will be determined by measuring its long dimensions.

LOW DENSITY AND SUBDIVISION PROJECTS
GENERAL SUBMITTAL REQUIREMENTS
1. A completed stormwater permit application.
2. Two sets of plans showing north arrow, scale, revision date, property/project boundaries, lot lines,
proposed and existing contours, drainage areas, mean high water line, wetlands, easements, the 30'
minimum vegetated buffer between impervious areas and surface waters, proposed impervious areas,
and road cross -sections.
3. Calculations of the build -upon area, for subdivisions, please show the methodology for arriving at the
per lot built -upon area. For non -subdivision projects, please break down the calculation into
buildings, roads, parking, and other (include all impervious areas).
4. Low density projects with curb and gutter will require:
a. Drainage area delineation and swale locations shown on the plans.
b. Detail of the swale, showing minimum 5:1 side slope.
C. Velocity calculations, indicating a non -erosive flow for the 10 yr storm.
d. Inlet and outlet elevations. Maximum longitudinal slope is 5%.
e. The type of vegetated cover specified on the plans.
DEED RESTRICTIONS REQUIREMENTS
The following statements must be included for all low density projects, and for all subdivisions:
No more than -;6.0, 220 square feet of any lot, including that portion of the right-of-way between
the edge of pavement and the front lot line, shall be covered by impervious structures, including
asphalt, gravel, concrete, brick, stone, slate or similar material, not including wood decking or the
water surface of swimming pools. This covenant is intended to ensure continued compliance with the
stormwater permit issued by the State of North Carolina. The covenant may not be changed or
deleted without the consent of the State.

The Wilmington Regional Office received a Stormmwater Management Permit Application for Evstam "!'.'
Car Lot on March 15, 1996. A preliminary revie of that information has determined that the application
is not complete. The following information is needed to continue the stormwater review:
1. Please add a detail for the points where the pavement exits into the Swale which leads into
the drop inlets.
2. Please note elevations along the pavement swale centerline.
3.. Please dimension the permanent pool_of the pond, the, building, -and a little more bf the -
parking lot. I calculate more building and parking than you do. Please -recheck your
impervious area calculation.'
