Dear Ms. Lewis,
Please find enclosed the response to your request for additional information for
the above referenced project:
1. We have revised the grading on the plans so that the circular drive
which appears on the plans will now flow to the pond.
2. The south dimension line for the permanent pool contour has been
moved and is no longer obscured by the drainage area line.
3. We have revised the plans to show that the area of the building as
19,166.40 S.F. We have check the area of the building and it was
incorrectly labeled as 19,263.97 S.F. as the plans indicate. In the "Site
Summary” on the plan that we submitted -to you, the building area was,
in fact, 19,166.40 S.F.
4. The corrections you made to the "Wet Detention Basin Supplement"
concerning the temporary pool and the forebay volumes are approved.
5. The supplement form has been now signed by the notary, Scott

STORMWATER NARRATIVE
1. GENERAL:
The 6632 Gordon Road site is located approximately one half mile west of the intersection of
SR1327 and US17, and approximately two miles east of the intersection of SRI327 and HWY
132, in the area of Ogden. The existing site occupies 1.79 acres, bound to the southeast by Dutch
Square Extension (MB #32, PG#334), to the northwest by Oliver Godwin (DB#779, PG#192),
and to the northeast by Gordon Road.
2. EXISTING CONDITIONS:
The existing drainage pattern is roughly from northeast to southwest, through two existing
shallow conveyance swales. Collected runoff from the property is currently discharged into an
unnamed tributary'of Smith Creek. Smith Creek is designated a SC stream class. Currently, no
off -site drainage enters the site.
3. PROPOSED IMPROVEMENTS:
The storm drain collection system will be expanded as shown on the attached plan to receive
runoff from the expansion area. All improvements proposed on -site, including proposed roof
drains, will drain to the proposed wet pond.
4. EROSION CONTROL CONSIDERATIONS:
At the time that disturbance is to begin a temporary construction entrance will be installed at the
Gordon Road entrance to the site. Silt fence will be installed as shown on the plan. Inlet sediment
protection (see detail) will be installed around each proposed catch basin to improve the
containment of sediment. Energy dissipaters will be constructed at the outlet of each drainage
system. The proposed pond will be utilized as a temporary sediment basin during construction
5. 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 shall be
repaired immediately. Upon completion of construction and establishment of permanent ground
cover, the Owner shall be responsible for maintenance on the project site.
6. STORMWATER CONSIDERATIONS:
All stormwater runoff is to be collected and conveyed to an on site detention/treatment to be
designed in accordance with Division of Water Quality regulations. To optimize land use, the
treatment pond has been oversized to fit the available space. The required surface area is 2729.03
sf, while the provided surface area is 5588 sf. For this reason, it may appear as if the required 3:1
length to width ratio has not been satisfied. However, at the minimum required surface area, the
3:1 ratio is satisfied. Please see attached calculations for additional treatment criteria.

01/1 /2ow)Q:Ii An
Erosion and Sedimentation Control
1.01 General: The contractor shall be responsible for erosion and sedimentation
control within the construction limits; for prevention of sediment laden runoff leaving the
construction limits or entering ditches, streams or water impoundments; and for
implementation of necessary erosion and sedimentation control measures to meet the
requirements of the North Carolina Department of Environment, Health, and Natural
Resources. The Contractor shall also be responsible for all damages or fines resulting
from erosion or sediment laden runoff in the execution of his contract.
1.02 Construction Sequence: While the use of erosion and sedimentation control
devices is especially important on areas of steep topography, easily erodible soils and
sites in close proximity to water courses throughout the construction period, the control
measures should be installed prior to the commencement of land clearing and shall be
fully maintained and periodically inspected until final restoration and stabilization is
completed. Unrestored cleared areas shall be kept to a minimum. Disturbed areas
ahead of construction shall only be accomplished on those segments for the shortest
practical distance as required for continual progress.
Final restoration shall not be delayed until completion of the project but will be carried
out in phases as the work proceeds. Under no circumstances will any areas be left
denuded for more than (30) thirty calendar days without some form of stabilization until
final restoration is complete.
1.03 Sedimentation: Control Measures: The following are some of the sediment
control devices or measures that may be required to prevent sedimentation of streams,
water courses, or drainage structures:
1. Earth berms and/or diversion and intercept ditches.
2. Sediment traps
3. Filter berms
4. Filter inlets
S. Silt fences - not to be placed in streams or ditches perpendicular to flow.
6. Check dams gravel filter
7. Gravel construction exit
1.03.1 Erosion Control Measures: Some of the soil erosion control measures which
may be required in this contract are:
l . Earth slope protection
2. Diagonal water break diversion berms
3. Diversion channels
4. Preservation of existing vegetation
Storm inlet protection
6. Stream crossings
7. Energy dissipators
8. Matting of re -seeded areas
1.03.2 Detail Drawing: Examples of sedimentation and erosion control details are
shown in these plans for installation at locations designated in the plans or as otherwise
required by the regulating agency, or the owner as work proceeds.
1.04 Stream Protection: Where construction activities are necessary in close
proximity to streams, and other waterways, they shall be performed in a manner that
does not contribute to degradation of or blockage of the stream -flow. In order to prevent
possible degradation or blockages, the contractor shall be required to:
1. Keep all construction debris, excavated materials, brush, rocks, refuse and topsoil
as far from these waterways as possible. Restrict machinery operation or stream
crossings in waterways to the extent necessary for construction of utilities crossings.
2. If construction work areas are necessary in a waterway, they shall be protected as
indicated on the plans.
3. If temporary roadways are essential for the construction activities, they shall be
constructed of soils which are not highly erodible materials and must not span more than
half way across the water course or wetland area at any one time unless otherwise
approved by the Engineer. These temporary roadways shall be entirely removed as soon
as their requirement is met. Work in these areas shall follow the requirements of the
Corp of Engineers or CAMA permit, or plans as applicable.
1.05 Construction Access: The travel of equipment to and from the construction
areas shall be minimized not only to protect areas that will not be denuded, but also to
prevent the spreading of sediment within and outside of the construction areas.
Therefore, special construction equipment travel corridors will be established for this use
and instructions shall be issued for their use. Use of these corridors must be fully
enforced. Other non -essential traffic will be restricted or discouraged. Indiscriminate
and convenience traffic shall not be allowed.
1.06 Stockpile/Barrow Areas: The Contractor shall be responsible for selecting,
obtaining and maintaining stockpile or borrow areas which he may require to complete
the contract. He is also required to design and incorporate all necessary sediment and
erosion controls measures necessary to prevent erosion and contribution of sediment to
adjacent areas. The Contractor is responsible to obtain all necessary permits or approvals
for borrow or spoil areas outside the construction limits.
1.07 Disposal of Excess Water From Excavations: The Contractor shall practice
management of excess water pumped from excavation to reduce the production and
spreading of sediment. Pumped water shall be discharged onto stabilized surfaces and
allowed to filter through existing vegetation if possible, otherwise, additional control
measures may be necessary. If ditches are required to remove pumped water from
construction excavations, they shall be given the same consideration as any other man-
made waterway and they shall be stabilized as to not degrade and produce sediment.
1.08 Excavation and Backfill: Excavation shall be closely controlled and all the
material removed from the excavation shall be selectively stockpiled in areas where a
minimum of sediment will be generated and where other damage will not result from the
piled material. Drainage ways shall be protected at all times and the placement of
material in Drainage ways for convenience shall not be allowed. Backfilling operations
shall be performed in such a manner that remaining trees are not damaged.
1.09 Final Grading and Seeding: Finish grading, topsoiling, seeding and/or sodding
shall be performed after the construction phase is complete. Permanent vegetation of the
areas, that have been disturbed, shall be re-established as rapidly as possible. If the
completion of the construction activities do not coincide with a season in which
permanent vegetation can be generated, an interim or temporary program is required.
This shall include soil conditioners and mulching as necessary for soil stabilization. In
any case, sediment and erosion controls shall be installed promptly and their maintenance
assured.
1.10 Approval: The approved Erosion Control Plan will be provided by the Owner.
Any standard conditions relating to soil erosion and sediment control issued to the
Contractor as a part of any permits shall be available at the job site at all times.
REQUIRED FOND 51ZE:
The pond size must be 1800 cu. ft per acre tames the area of disturbance in
acres to function as a sediment control basin.
Area of disturbance= 1 .79 acres
(1 800 cflacre)X 1 .79 acres)=3222 sf
Proposed pond size at an elevation of 52 ft is 5588 sf x G' deep
33,528 sf > 3222 sf = size required OK
Therefore, the proposed wet pond will function as a sediment control basin
during construction.

Subject: ACKNOWLEDGMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 000526
Expostar Portable Displays
New Hanover Count,
Dear Mr. Carter:
The Wilmington Regional Office received a Stormwater Management Permit Application for Expostar
Portable Displays on May 11, 2000. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the stormwater review:
I. Please report small areas in square feet rather than acres on the application. It makes it much
easier to verify the numbers.
2. What is the normal water level in -the receiving ditch? Please keep in mind that blockages and/or
flooding problems in outlet ditches will not be considered as justification for not providing the
required 2-5 day.drawdown time. Please make sure that the effect of a high water level in the
ditch has been considered in the design of this pond.
Please provide sufficient contours and spot elevations in the parking lot to verify drainage into
the pond.
4. Please reduce the 6" o.c. rebar for the trashrack to no more than 3)%4".
The calculations indicate that the volume provided at elevation 52.7 is 4,182 cubic feet, but it
appears that number is based on the average surface area between 52 -and 53, not 52 and 52.7.
Pleas:; corrcrt. Whi2c :sufficient volume is still provided using the average surface are between 52
and 52.7, the error must be corrected. Please submit a revised and settled page 2 of 3.
