Nuckolls, Member/Manger CCHC Properties, LLC PO Box 12248 New Bern, NC 28561 Subject: Stormwater Review SW7060704 Coastal Carolina Health Care Craven County Dear Mr. Nuckolls: This office received a Coastal Stormwater permit application and plans for the subject project on July 18, 2006 followed by additional information on August 1, 2006. A preliminary review of the project indicates that before a State Stormwater permit can be issued the following additional information is needed. ➢ Please note that the permanent pool is given as 21.00 furs] on both the Wet Detention Pond Section and the Outlet Control Structure details, but the newly revised wet detention basin supplement form gives the new permanent pool at 19.5fmsl, please revise either the supplement form of plans. Please also check and revise the bottom elevations on the pond plan view and cross sectional detail to correspond to the supplement form. ➢ The calculations submitted also gives the permanent pool elevation as 21.00 fmsl and does not match the new supplement form. Please revise all necessary calculations to show the new bottom, permanent and temporary pool elevations. In addition please show the new elevations in the small diameter orifice draw down calculation. ➢ The Wet Detention Pond cross section and plan view gives the forbay wall at 21.08fmsl. Because this wall is helping to add to the length of the pond in order to meet the 3:1, L:W requirement, the forebay wall should be as high as the temporary pool elevation, 22.2 fmsl, so that no polluted stormwater washes over the wall thereby having a shorter flow path towards the outlet. Please raise the forebay wall on both the detail and plan views up to at least the temporary pool elevation. ➢ Page 3 of 4 of the wet basin supplement form also needs to be revised to show the new elevations as proposed on the Wet Detention Basin Supplement form. ➢ Please remember to have all plans and calculations that are resubmitted signed and sealed by the engineer. The above requested information must be received in this office prior to August 8, 2006 or your application will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the application fee. If you need additional time to submit the required information, please mail or fax your request for time extension to this office at the Letterhead address. You should also be aware that the Stormwater Rules require that the permit be issued prior to any development activity. Construction without a permit is a violation of 15A NCAC 2H.1000 and North Carolina General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.

The wet detention pond is the only measure being utilized for permitting this project to meet the DWQ storm water rules and it is sized to remove 90% TSS without a vegetative filter. The pocket wetland is used in conjunction with the wet pond for meeting nutrient reduction limits in the Neuse River Basin. Runoff from this site eventually drains to an Wilson Creek a tributary of the Trent River in the Neuse River Basin. The property is bounded by existing commercial uses to the west and east and by Wel Ions Road on the northwest. The purpose of this design is to reduce TSS by 85% in a project located in the 20 coastal counties for the new impervious development on this site. The required surface area of the pond is 15305 sf . The surface area provided is 16,988 sf. The wet detention pond is sized bas;Ad on 6.0 feet of depth but is excavated to 6.5 feet of depth to provide for sediment storage during construction. The wet detention pond as designed will STORM WATER MANAGEMENT NAI COASTAL CAROLINA HEALTH CARE CRAVEN COUNTY, NORTH CAROLINA remove 90% TSS. The completed project will consist of one 9.42 acre drainage area draining into the proposed stormwater pocket wetland via the proposed storm drainage system.

Director Division or Water Quaiizv Julv 27, 2006 Mr. Stephen W. Nuckolls, Member/Manger CCHC Properties. LLC PO Box 12248 New Bern, NC 28561 Subject: Stormwater Review SW7060704 Coastal Carolina Health Care Craven Countv Dear Mr. Nuckolls: This office received a Coastal Stormwater permit application and plans for the subject project on July 18. 2006, A preliminary review of the project indicates that before a State Stormwater permit can be issued the following additional information is needed. The narrative states that the wet detention pond is the only measure to be utilized for meeting the State Stormwater Permitting Requirements. Please provide design calculations on just the wet detention pond showing the draw down, surface area and volumes required and provided. There is some concern on how the 22,193 cubic feet of storage is being provided in just the wet detention pond from elevation 21..00 to 21.68. It appears that the wet pond and pocket wetland are used in combination to meet the minimum 1" storage volume requirement. This combination cannot be accepted because the pocket wetland is only designed to meet 35%TSS removal. The original model for the 85-90%TSS removal wet pond does not account for half of the area to be considerably less in depth. Please add a trash guard/grate to the small overflow weir on the outlet control structure detail. 1-1 Please note that the temporary pool is given as 21.68 fmsl and the weir is at 21.63fmsl. please revise. The Wet Detention Pond Section gives the forbav wall at 21.08fms1, but the plans give 20.08fmsi. Because this wall is helping to add to the length of the pond in order to meet the 3 i L L:W requirement. the forebav wall should be as high as the temporary pool elevation so that no polluted storm%vater washes over the wail thereby having a shorter flow path towards the outlet. Please raise the forebav wall on both the detail and plan views. Page 3 of 4 of the wet basin supplement form also needs to be revised to show the new elevations. > Please provide the 25% additional information fee associated with the Express S€orinwater Review Program of $1000.00 by check made payable to "NC DENR". The above requested information must be received in this office prior to August 3, 2006 or your application will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the application fee. If you need additional time to submit the required information, please mail or fax your request for time extension to this office at the Letterhead address.

The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet). b. The forebay volume is approximately equal to 20% of the basin volume. c. The temporary pool controls runoff from the design stone event. d. The temporary pool draws down in 2 to 5 days. e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive now calculations) £ The basin length to width ratio is greater than 3:1. g. The basin side slopes above the permanent pool are no steeper than 3:1. h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail). i. Vegetative cover above the permanent pool elevation is specified. j. A trash rack or similar device is provided for both the overflow and orifice. k. A recorded drainage easement is provided for each basin including access to nearest right- of-way. 1. If the basin is used for sediment and erosion control during construction, clean out of the basin is specified prior to use as a wet detention basin. m. A mechanism is specified which will drain the basin for maintenance or an emergency. Ill. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one) 0 does does not incorporate a vegetated filter at the outlet. This system (check one) does [] does not incorporate pretreatment other than a forebay. Form S WU- 102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: l . After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention basin system for sediment accunuilation, 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, mow vegetative cover to maintain a 111aXlnittm 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 quality (Le. stockpiling near a wet detention basin of stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 4.87 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 4.87 legit in the forebay, the sediment shall be removed.

NORTH CAROLINA 27834 TEL 252.756 1390 FAx 252.321.1412 www.BALDWINDESIGNCONSULTANTS.com PROJECT DESCRIPTION: The purpose of this project is to remove stock -piled spoil off an area of 1.790 acres. This area was previously shown on plans as future development and during the construction of the existing buildings, parking lot and stormwater pond the excess material was placed at this location. This property is located at the eastern end of Renfrow Place, New Bern, North Carolina. The anticipated date for start of construction is September 2015. The construction process should take approximately 2 months with the temporary seeding will occur within seven (7) calendar days after completion of any phase of grading or the cessation of grading on all perimeter slopes and slopes steeper than 3:1, all other disturbed areas will be stabilized with appropriate ground cover within 14 calendar days. SITE DESCRIPTION: This project is moderately sloped with grades of about 3.00%. Existing surface drainage is currently sheeting to the north, south and west and accumulating in the existing drainage system to the north, the existing stormwater pond to the east and the existing parking lot to the south. Run-off after spoil is removed will continue in these same directions but with a flatter slope over vegetation. ADJACENT PROPERTY: Property is bounded on the north by wooded land and a medical office, bounded on the east by a stormwater pond, bounded on the south by a parking lot and bounded on the west by wooded land. Due to the proposed plan of drainage, surrounding properties should not be adversely affected by the construction process of this development. SOILS: The soils in this area are a sandy loam variety with the proper soil name being Torhunta. There will be an average amount of soil exposed at one time and with proper installation of erosion control structures, excessive run-off should be minimal. This site is shown on Map 12 of the Craven County Soil Survey. PLANNED EROSION CONTROL DEVICES TEMPORARY GRAVEL CONSTRUCTION ENTRANCEIEXIT: This structure will be installed at the north side of the parking lot entrance as shown on plans. This gravel pad will be checked periodically and scarified if necessary to insure proper performance. SILT FENCE: Install silt fence as specified on plans.
