Let's simplify this volume calculation. Forget about the thickness of the chamber.
It apears that the thickness of the polyethylene is minute compared to the overall
volume. The thickness of a round pipe wall is ignored in other applications, so a
Cultec chamber should not make any difference.
You cannot count the trench volume above the weir overflow elevation as part of the
volume provided. The overflow weir elevation in the Special Infiltration Drop Inlet
is set at 40.45, therefore the total volume of the trench is 14' W x (40.45-39.5) x
791 = 10,520 cubic feet, not 22,609.4. The volume of 422 Cultec units that are
7.5' long at 1.86 cubic feet per linear foot is 5887 cf. Subtracting 5887 from
10,520 leaves 4633 cubic feet of stone, or 1,853 cubic feet in the voids (@40%)-
The total volume provided is 5887 plus 1853 = 7,740 cubic feet, not 12,517. The
7,740 is more than enough to satisfy the minimum volume requirement.
Please revise the calculations again to reflect the correct trench depth and volume
provided.
Thanks, Linda

The Division received a Stormwater Express Permit Application for the subject project on
July 23, 2004, with a scheduled review date of July 26, 2004. The application is incomplete.
Please provide the following information to complete the review:
1. Please provide sufficient calculations to support your conclusion that 8,022 cubic feet of
volume has been provided. I am unable to figure out how you reached this conclusion. It
appears that the total volume that each Cultec unit takes up in the trench is 2.97 cubic feet
per linear foot. If each unit is 7.5' long, and there are 315 units, then the volume taken up
by the units inside the trench is 7,024.5 cubic feet. The trench itself has a total volume
12,355 cubic feet. Subtracting 7024 from 12355 is 5331, multiply by .4 (void ratio), the void
volume is 2132 cubic feet. Each unit will store 1.86 cubic feet per linear foot, so if each unit
is 7.5' long, each unit provides 13.95 cubic feet of storage volume. The total volume
becomes 13.95 times 315 plus 2132 or, 6,525 cubic feet. Please adjust these numbers as
needed.

My biggest problem in verifying the calculations is that the Cultec system
calculation sheets you originally submitted indicate that the space taken up by the
chamber itself in the trench is 2.97 cf / lf, leaving only 2,132 cf in the stone
voids.
Additionally there is conflicting information regarding the storage capacity. The
original Cultec calculation sheets you provided indicate that the volume of the
Contactor 100 is 1.86 cf / lf, while the most recent information you sent over has
another sheet (Design Notes) that shows it as 2.2 cf / lf. Which is the correct
volume?
Your use of the Rational formula for volume combined with the BUA error (91,135
actual vs.91,835 used) is also causing the minimum volume to be more than
necessary. If you used Schuler's method, and the correct BUA and the 2.97 cf / if
volume, then the total volume to be stored is about what the chambers provide, 7330
cubic feet.

Subject: Volume'of HMWHDPE material in Cultec Contactor 100 HD Chamber.
Dear John,
Cultec Contactorl00 HD chambers are manufactured by vacuum
thermoforming process,and produced with High Molecular Weight High Density
Polyethylene having a starting gauge of 0.325 inches.
The C-100 is 3-feet wide.
In calculating material volume:
(0.325 inches / 12 inches/foot) X 3 feet wide X 1 foot long = 0.08 cubic
feet of material per linear foot of'Contactor 100 HD chamber.
John, if you.have any questions, give me a call.

To: John Tunstall <jstun stall @nkteng.com>
John:
we need to come to an understanding about the provided volume in this Cultec
System. Based on the area of a parabola, (base x 2/3 height) I have calculated
that the volume of the entire chamber (outer edges) is roughly 15 cubic feet,
allowing for the -area between the ribs.
This means that the stone void volume in the trench is 3052 cubic feet. At 1.86
cubic feet per linear foot, 315 Contactor 100 HD-20 Cultec units will provide 4,394
cubic feet of volume. Total volume provided in the system (ignoring catch basin
volume and piping) is 7,446 cubic feet.
Can you agree with this calculation? If you want to add the 61, of stone and the
catch basin piping, please advise and submit revised calculations.

your comments.
1. 1 have met with the Cultec Representative and the referenced
material I had for the system was incorrect and outdated. Please
find the revised hand calculations that reflect the actual volume of
the chambers and trench. The 2.97 cf/ft listed in the Cultec
spreadsheet is the average volume for single unit with stone. Also
please see revised calculations for correct volume.
2. Please find the corrected page 2 of 4 of Application & SWU 107

WITZORTWIMA
DESCRIPTION:
The site is located within the Wilmington City Limits on Racine Drive consisting of sandy
soils and grades ranging from 1% to 2%. Approximately 3.09 acres will be graded to
allow the construction of 3 — 2 story office buildings with paved parking and access.
The runoff from the site is estimated using the rational method 10-year design storm
and rainfall data for the area. Construction is scheduled to begirt as soon as all permits
and approvals are obtained.
EROSION CONTROL MEASURES:
The attached plans and specifications give the requirements for erosion control
measures. Silt fencing will be provided where stormwater would be expected to sheet
flow from disturbed areas directly to adjacent property. Inlet protection will be provided
at all existing inlets near land disturbance. A gravel construction entrance will be
constructed at the entrance to the site on Racine Drive. Maintenance will be provided
by the grading contractor.
STORMWATER MANAGEMENT MEASURES:
The stormwater from the new office buildings, parking and drive area will be designed
to sheet flow to an underground infiltration system located on the north and south sides
of the proposed buildings. The infiltration system will store and infiltrate the first 1-inch
of runoff and the additional runoff volume above the first 1 inch will be bypassed in
accordance with NCDENR Regulations. The system will also be designed to the City of
Wilmington stormwater standards.
CONSTRUCTION SEQUENCE:
The Contractor will install the gravel construction entrance and silt fence prior to
beginning any clearing and grading operations. Additional silt fence will be installed
when and if conditions warrant during construction. The silt basins will be constructed
immediately after that portion of the site is cleared, and outlet structure with protection
will be installed. Disturbed areas will be landscaped or seeded upon completion.
MAINTENANCE PLAN
�. 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 accumulating sediment after
each rain event. In addition to erosion control around drop inlets, install silt sack
or equal, under the grate of the structure until the project is complete. 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. 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.
8. More stringent measures shall be used to halt erosion if those shown on this plan
are not effective.
9. All erosion shall be controlled including side slopes before the project is
completed.
10. Remove temporary measures upon completion of project. All permanent
measures will be well established before project closeout.

SECTION 02920
SOIL EROSION AND SEDIMENTATION CONTROL
1. GENERAL
1.1 Contractor shall take every reasonable precaution throughout construction to
prevent the erosion of soil and the sedimentation of streams, lakes, reservoirs, other

3. EXECUTION
3.1 General: Take every practicable measure during construction or suspension to
work to minimize erosion and siltation. Measures should include good construction
practices, temporary physical barriers to sediment travel, settling basins for new ditches,
and establishment of vegetative cover.
3.2 Construction Practices
3.2.1 Avoid dumping soil or sediment into any wetland or watercourse.
3.2.2 Maintain an undisturbed vegetative buffer where possible between a natural
watercourse and trenching and grading operations.
3.2.3 Avoid equipment crossings of streams, creeks, and ditches where practicable.
3.2.4 Grade all cut, fill and ditch slopes to minimum slope of 3:1, unless otherwise
shown or directed.
3.3 Temporary Physical Barriers are required where sedimentation on off site
property or excessive erosion is a problem.
3.3.1 Mulch shall be used for temporary stabilization of areas subject to excessive
erosion and for protection of seedbeds after planting where required.
1. Apply grain straw and hay at a rate of 75 to 100 pounds per 1000 square feet
and wood chips at a rate of 500 pounds per 1000 square feet. Jute and mesh
should be installed as per manufacturer's instructions.
2. Asphalt emulsion for slope stabilization should be applied at a rate of 1,000
gallons per acre. Asphalt emulsion used for anchoring straw should be
applied at a rate of 150 gallons per ton of straw.
3.3.2 Silt Fences shall be used at the base of slopes to restrict movement of sediment
from the site. Clean silt fence of accumulated sediment after each rainfall event or
when it exceeds a depth of 0.5 feet above natural grade.
3.3.3 Stone Check Dams, placed at the discharges of creeks, ditches, and swales,
shall consist of Class A rip rap at minimum two feet high and three feet thick across the
I
watercourse, with a one foot thick layer of gravel on upstream side. Remove sediment if
accumulated to a depth of 1.0 feet at upstream face.
3.4 Vegetative Cover: Establish and maintain permanent vegetative cover on all
unpaved areas disturbed by the work.
3.4.1 Preparation of Seedbed: Areas to be seeded shall be scarified to a depth of 4
inches and until a firm, well pulverized, uniform seedbed is prepared. Lime, phosphorous
and fertilizer shall be applied during the scarification process in accordance with the
following rates:
Lime: 45 pounds per 1000 square feet
Phosphorous: 20 pounds per 1000 square feet
Fertilizer: 17 pounds per 1000 square feet
3.4.2 Seeding: Disturbed areas shall be seeded with 2 to 3 pounds per 1000 square
feet of the specified seed mixture. Seed shall be worked into the bed to a depth of 114
inch. Regrade and seed eroded areas immediately
3.4.3 Mulch all areas immediately after seeding. Mulch shall be applied and anchored
as specified hereinbefore. Reapply as necessary to retain cover until grass is
established.
3.5 Construction Entrance: Provide an aggregate drive, 20 feet wide by 50 feet long
by B inches thick at each entrance to the site used by construction vehicles, until such
time as the permanent roadway is constructed. Remove soil if accumulated to a depth
greater than 0.5 inches.
3.6 Maintenance: The Owner and Contractor shall be responsible for maintaining all
temporary and permanent erosion control measures. Temporary structures shall be
maintained until such time as vegetation is firmly established in the area protected by
the structure. Permanent streambank protection and grassed areas shall be
maintained until completion of the project. Areas that fail to show a suitable stand of
grass or which are damaged by erosion shall be immediately repaired.
