Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built -upon" area consistent with the design criteria used to size the stormwater control facility. I, Bert Exum acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any outparcel or future development area: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number SW8 030120, as issued by the Division of Water Quality under NCAC 2H.1000. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum built -upon area for the outparcel(s) shown on the approved plans is as listed below: OUTPARCEL# BUA OUTPARCEL# BUA 1 56,397 SF 7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures.

Regarding the fore bay'(the other comment), the pond needs to be dipped, so I could leave a foot in the bottom yielding a 3 foot deep fore bay that would probably get me back in the required volume range if I flatten the side slopes a bit. If the numbers verify my suspicion, is 3 feet deep acceptable for the fore bay? -----Original Message ----- From: Linda Lewis [mailto:linda.lewis@ncmail.net] Sent: Tuesday, March 20, 2007 9:57 AM To: Davis Fennell Subject: Another comment RE: Waterford Way SW8 030120 Mod.

From: Linda Lewis <linda.lewis@ncmai1.net> Date: Tue, 20 Mar 2007 08:47:58 -0400 To: Davis Fennell<davis.fennell@capefearengineering.com> Davis: The Division received previously requested information regarding the subject stormwater permit application on January 11, 2007. Please submit the following information by Tuesday March 27, 2007, to make the application complete: The forebay for the pond is now too large. The acceptable range of forebay volume is 18%-22% of the permanent pool volume. This pond proposes a forebay that is 24% of the permanent pool volume. Since this pond is not oversized, please reduce the size of the forebay so that it contains a volume that is no less than 6,928 cubic feet and no more than 8,467 cubic feet.

P.O. Box 1967 Wilmington, North Carolina 28402 (910)540-9716 Date: September, 2006 REVISED: JANUARY. 2001 'RECEIVIED JAN 11 2007 Prepared by DwQ,,I� N U() Cape Fear Engineering, Inc. 5wav 151 Poole Road, Suite 100 Belville, North Carolina 28451 (910)383-1044 DESIGN NARRATIVE L GENERAL: The project site is located off of Hwy 17 at Poole Road in the Waterford Development within the city limits of Leland in Brunswick County, North Carolina. The project area for the commercial site is approximately 5 acres. Drainage considerations are to be in accordance with DEM storm water requirements. 2. EXISTING SITE: Site topography in the area is relatively flat with slopes typically less than one (1) percent. The vegetation consists primarily of grasses and minor ground cover within the area of the improvements. Subsurface soils are typically a mixture of sands, silty sands and organics. The stormwater pond proposed for this site is now existing and stabilized. 3. PROPOSED IMPROVEMENTS: Improvements proposed include the construction of three commercial buildings with required parking. The site will be graded to divert all storm water runoff into curb inlets and drop inlets to the now existing storm water treatment pond. There is one lot proposed for sale to be developed by others that will also drain to the existing treatment pond. The permanent pool will be deepened by 1 foot, making the pond 7 feet deep. The six foot shelf will also be removed from the fore bay as it is not required and will generate the required volume in the fore bay for the enlarged permanent pool. 4. DRAINAGE CALCULATION CONSIDERATIONS: Attached to this design narrative are the drainage calculations determining the amount of storm water to be contained and treated prior to entering any downstream surface waters. The proposed design for this project is to be a storm water treatment pond designed to the NCDENR requirements for 90% TSS removal. 5. EROSION CONTROL CONSIDERATIONS: The proposed storm water pond will be used as a trapping device during construction and has sufficient storage for the calculated amount of disturbance. Also, the North, West and South perimeter will be enclosed in silt fence as added protection for the existing ditch along the property lines. The area of disturbance is limited to within the 5 acre project area. Maximum graded slope is not to exceed three (3) to one (1) with vegetative establishment a priority. 6. 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 its intended function, shall be repaired immediately. Upon completion of construction the establishment of permanent ground cover will be a priority.

(2 to 5 day temporary pool draw -down required) Design Rainfall I in. Design TSS Removal 2 90 % (minimum 85% required) Form: SW U-102 Rev 3.99 Page 1 of 4 Footnotes: When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non- standard table entries. 2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide 90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal. II. REQUIRED ITEMS CHECKLIST The following checklist outlines design requirements per the Stormwater Best Management Practices Manual (N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code Section: 15 A NCAC 2H .1008. Initial in the space provided to indicate the following design requirements have been met and supporting documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit Application Form, the agent may initial below. If a requirement has not been met, attach justification. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet). The forebay volume is approximately equal to 20% of the basin volume. The temporary pool controls runoff from the design storm event. The temporary pool draws down in 2 to 5 days. If required, a 30-foot vegetative filter is provided at the outlet ( include non -erosive flow calculations) The basin length to width ratio is greater than 3:1. The basin side slopes above the permanent pool are no steeper than 3:1. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail). Vegetative cover above the permanent pool elevation is specified. A trash rack or similar device is provided for both the overflow and orifice. A recorded drainage easement is provided for each basin including access to nearest right - of —way. 7 I. 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. AA A mechanism is s ecified which will drain the basin for maintenance or an emergency. Tml 1 III. 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 X does not incorporate a vegetated filter at the outlet. Form: SWU-102 Rev 3.99 Page 2 of 4 This system (check one) 0 does X does not incorporate pretreatment other than a forebay. Maintenance activities shall be performed as follows: After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention basin system for sediment accumulation, 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 maximum 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 (i.e. stockpiling near a wet detention basin or stream, etc.) The measuring device used to determine the sediment elevation shall be as such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 5.25 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 3 feet in the forebay, the sediment shall be removed.
