President Attest: Racine Office Complex SW8 040720 Subject: Racine Office Complex SW8 040720 From: Linda Lewis <Linda.Lewis@ncmail.net> Date: Tue, 17 Aug.2004 16:43:28 -0400 To: John Tunstall <jstunstall@kteng.com> worm "S 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.

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. 2. What is Mr. Eason's title within the corporation? sr 3.

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.

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. Bob DiTullio / Cultec Inc.

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.

Thank you. John Tunstall At 06:31 PM 7/28/04 -0400, you wrote: John: 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.

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. 11 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 water impoundments, ground surfaces, or other property as required by State and Local regulations. 1.2 The Contractor shall install all required silt fences, and construction entrances at the initiation of work, and have these measures reviewed and approved by the local permit authority prior to clearing and grading operations. 1.3 The Contractor shall, within 15 days of suspension or completion of land disturbing activities, provide permanent protective covering for disturbed areas. Temporary and permanent erosion control measures shall be coordinated to assure economical, effective, and continuous erosion and siltation control throughout the construction and post -construction period. Use the specified seed for both temporary and permanent seeding. 2. PRODUCTS 2.1 Asphalt for anchoring mulch shall be Type SS-1 Emulsion. 2.2 Fertilizer shall be 10-10-10 grade or equivalent. 2.3 Lime shall be dolomitic agricultural ground limestone containing not less than 10 percent magnesium oxide. 2.4 Mulch shall be small grain straw, hay, wood chips, asphalt emulsion, jute or other suitable material free of undesirable weed seed. 2.5 Phosphate shall be 20 percent superphosphate or equivalent. 2.6 Seed shall be 20% carpet grass, 24% Bermuda, 20% turf Fescue, 10% Creeping Red Fescue, and 24% Annual Rye grain. Bermuda seed shall be hulled for warm weather planting and unhulled for cool weather planting. Purity of seed shall be a minimum of 98 percent and germination shall be a minimum of 85 percent. 2.7 Silt fence shall consist of NCDOT Class A fabric supported by wood or metal posts spaced not more than 6 feet on center. The bottom of the fabric shall be buried a minimum of 6 inches. 2.8 Gravel for check dams shall be #57 washed stone_ 2.9 Aggregate for construction entrance shall be #4 washed stone. 2.10 Stone rip rap for check dams and erosion control shall be NCDOT Class A or B as shown. 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.
