STROUD ENGINEERING, P.A. CONSULTING ENGINEERS 102-D CINEMA DRIVE 2006/vILMINGTON, NORTH CAROLINA 28403 (910) 815-0775 t Division of Water Quality Attn: Ms. Linda Lewis 127 Cardinal Drive Wilmington, NC 28409 Re: Andrew's Reach, Phase II-SW8 050414 Mod Dear Linda, Attached please find updated plans and calculations for the reference site. Per your request, I have changed several details on the plans and would request your consideration for approval and issuance of a stormwater permit for the site. Namely, 1 have made the following changes as listed below: • As discussed in our previous email communications, the basis for selecting slot elevations for the basins permitted in Phase I was to control the rate of post development flow in accordance with City regulations as well as contain the first inch and half of runoff and require that volume to slowly drawdown into the infiltration trench system. 1 have attached the original calculation faxed to Rob Gordon when we permitted Phase I illustrating the slot elevations and volumetric calculations. • The bottom elevation of Basin I may have been listed at 7.0 on an application form when Please I was permitted, however on my set of approved Phase I drawings it shows the outlet orifice at 8.0 elevation and the slot at 10.0 elevation. This was how the basin was constructed. In any rate, the required storage below the slot has been achieved by setting the slot elevation at stage 2.0 or elevation 10.0 (pond volunetrics and depth are the same, the elevations were changed to avoid bubble -ups at curb inlets during floods) which guarantees the required storage for the treatment volume. I have updated the outlet structure detail on the attached drawings to indicate the correct elevations. The proposed outlet structure modification will guarantee both post development flow containment as well as provide the required 2-5 day drawdown for the treatment volume. • 1 have specified bottom elevations for both the new Phase 2 basin as well as for the existing Please I basin. Note that I have labeled the Phase I basin I bottom elevation as 8.0 as previously discussed. • As indicated in my previous email, the bio-retention structure is needed in the cul-de-sac island and was included at the recommendation of the City. It is not intended to provide any documented State water quality treatement benefits. It certainly will not be built to typical bio-retention basin standards as required for State water quality treatment, but we thought it would be a welcome addition to provide some undocumented benefits. I hope these explanations make sense of this complicated permit modification. If I can be of further assistance, please don't hesitate to let me know.

From: "Zachary Shipman" <zshipman@stroudengineer.com> Date: Thu, 16 Mar 2006 17:02:55 -0500 To: "Linda Lewis" <linda.lewis@ncmail.net> Linda, Sorry for the delayed reply --I have been out sick for the past few days. I am reviewing our permit for this project to compile the needed information. I will try to address your concerns the best I can: --The outlet structure slot elevations were selected with two goals in mind; first was to provide storage for the first inch and half while simultaneously providing pre and post detention control to meet City standards. The hydraulics of the system are pretty complex, so we attempted to meet each pre and post requirement at each individual basin instead of the overall system as a whole. --The bottom elevation for Basin 1 is 7.0 with a top of 12.0. This is how the basin was originally permitted. For some reason, I copied an older version of Basin 1 into the Phase II drawing showing the bottom at el. 8.0 with a top of 13.0. The volumetrics are identical, just a mislabeling of elevations. I will correct this on the next set of drawings. --The detail for the Basin 1 outlet structure modification is in error which will also be corrected on the next set of plans. Note that the only reason that I have included a Basin 1 outlet structure modification is because of the addition of some impervious to the access road leading into the Condos between the two ponds (for pre -post control). I counted this impervious towards the amount already alloted for "future development" in the original permit so the water treatment would be homogenious across the site. --The bioretention structure detail is for a depressed area in the cul-de-sac island which was a recommendation by the City in our preliminary design. This area is not intended to be permitted as a treatment BMP by the State, so I have not included it in our permit modification. The developer desired a less rigorous planting requirement for the area, so we chose not to use it as a BMP, but rather as an "extra" --Lastly I am running numbers for the treatment volume and will forward our conclusions as soon as I can, but I wanted to give you the info I have readily available. The original permit was pretty complicated and I know all the numbers jived when we permitted it. I will get back with you with that info as soon as I can. If you want to sit down and discuss, I can do so anytime next week. Just let me know, Thanks, Zak Shipman -----Original Message ----- From: Linda Lewis [mailto:linda.lewis®ncmail.net] Sent: Tuesday, March 14, 2006 12:34 PM To: Zachary Shipman Cc: jimmy fentress; Robert Gordon Subject: Andrews Reach SW8 050414 Mod. Zak: I'm having a little trouble duplicating the previously permitted volume of 43,755 cubic feet. Rob could not explain some of the calculations to me, so I went back to gain an understanding before I modified the permit. As I understand it, the four City basins provide storage for 1.5" of runoff from their respective drainage areas while it's being decanted via the orifice into the infiltration trench system. The I oft 3/20/2006 3:45 PM RE: Andrews Reach SW8 050414 Mod. orifice is located at the bottom of each basin to ensure that it drains completely and dries out between storms. Please be aware that submitting a modification essentially opens up the whole permit to review again. Keep this in mind when reading the remainder of this email. My questions are: 1. Each basin has an outlet structure with an overflow slot set at a specific elevation. What was the basis for choosing this elevation? 2. The calculations dated June 13, 2005, indicate that 3,333 cubic feet of volume is infiltrated during the storm event. We do not allow the volume that is infiltrated during the storm event to be counted or subtracted from the required minimum storage volume to be provided in the system. However, since it was previously permitted we will continue to allow it under this modification. In the future, please do not include the volume that is infiltrated during the storm in the calculations. The net volume to be stored is reduced by 3333 to 41,530 cubic feet. 3. Has the bottom elevation for Basin #1 been raised to elevation 8? It was previously approved with a bottom elevation of 7.0. The basin volume calculations you submitted with this modification start at elevation 8.0. When I go back and recalculate the volumes provided in each basin from the bottom elevation to the overflow slot (based on the June 13, 2005 calculations for Basins 2, 3, & 4 and the December 29, 2005 calculations for Basin 1) I am coming up with approximately 12,500 cubic feet total for the basins. Adding this to the 6,786 cubic feet provided in the 960 linear feet of infiltration piping, and the 20,226 provided in the trench system, the grand total is only 39,178 cubic feet, which is 2,352 cubic feet short. Perhaps some of the other overflow slot elevations could be raised up to provide the additional volume and included in this modification. 4. The detail of the existing release structure for Basin 41 is incorrect- the elevation of the overflow slot is shown as 10.0 and the orifice invert is shown as 11.0. (That doesn't make sense, anyway). Please revise the overflow slot elevation to 9.0 and the orifice invert to 7.0, as previously permitted. 5. The originally approved plans do not specify the bottom elevations for any of the City storage basins. Please add the bottom elevations to the basin section detail showing the clay liner. 6. Sheet 8 of 9 of the Phase II plans submitted on January 3, 2006, show a "Bio Retention Area Outlet Structure" detail. I don't see where the original permit included a bio-retention basin. Why is this detail on the plans? Reviewing a modification to a permit that I didn't write in the first place can be messy. For my own enlightenment, we may need to schedule a meeting to get this straightened out, unless you have the answers. Let me know.

Per your letter of December 2, 1 have made several revisions to the plan and are resubmitting for your review. I have attempted to structure this resubmittal towards combining both the previously permitted Phase I system and new Phase 2 system into a combined infiltration system. Namely, several of the modifications are as follows: • The previously issued permit for Phase I included a drainage area of 17.41 acres. An allotment of 34,000 sf of impervious was included in this area to provide additional space in the trench system for Phase 2 development. The 2.01 acres of drainage are were not included in the area because we knew at the time a City detention basin would be required. I have changed the drainage area to be the correct 19.42 acres in the calculations and also reworked the calculations to verify the adequacy of the combined Phase 1 and Phase 2 system capacity. This determination is based on an overall volume calculation for the combined system. Volume for the new Phase 2 is to be detained below the overflow slot in the new Phase 2 detention basin and routed to the trench system. • 1 have attached draft covenants for the overall project (Phase I and 2). No map has been recorded for Phase 1 as of yet and no lots have been sold. These covenants will be recorded prior to the sale of any lots. • The dimension for driveway width has been added to the detail. • The typical cross section has been corrected with regards to sidewalks. Sidewalk will only exist on one side of the street as shown. • Calculations are now for the combined 19.42 acres drainage area and total impervious surface quantity. A calculation for the localized effect of Phase 2 has been included to ensure that we do not surcharge the system at the new Phase 2 area. • The application has been corrected as required to stale "Footings of Wilmington, Inc" as well as call the modified permit "Andrews Reach Phase I & It." We understand that the modified permit will include both Phase I and 2 systems as a combined system and be revised as a residential permit in lieu of the incorrect commercial permit previously issued. Also please note that some changes have been made as a result of City ordinance requirements since our last submittal. All impervious area figures have been corrected on the plans, application and calculations. Please consider this resubmittal towards the issuance of a stormwater permit such that we may move forward towards project construction.

Director Division of Water Quality The Wilmington Regional Office received a modified Stormwater Management Permit Application for Andrews Reach Phases I and II on September 22, 2005. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: The previously approved drainage area for this entire project, including the future development area, was 17.41 acres. Please explain how the project's drainage area is now 19.42 acres, when no additional area has been added. 2. Please submit a copy of the previously recorded deed restrictions for Phase I, if any lots in that phase have been sold. If no lots have yet been sold, please advise. 3. Please add the width of the driveways to the typical building detail. 4. The road detail includes a 7' sidewalk, however, no sidewalk is shown on this plan adjacent the proposed cul-de-sac. If sidewalk is not planned for Phase II, please remove it from the road detail. 5. The previously permitted total volume provided in the trench and City basins was 43,755 cubic feet. The addition of the new City basin adds an additional 6,502 cubic feet of storage volume. Do you agree that the total provided volume in this system is now 50,257 cubic feet? If so, please state the total volume provided in the trench/basin system somewhere in the calculations. 6. Please report an accurate corporate name on the application. The application lists "Footings of Wilmington, NC", however the Secretary of State has no listing for a corporation under that name. I believe the correct corporate name is "Footings of Wilmington, Inc.". If you concur, please revise the application accordingly. The original permit was erroneously written as a commercial high density project. The modified permit to be issued upon receipt of a complete application will be for a high density subdivision to correct this error.

Please note that the modified permit will cover both Phases I and I I, so the project name on the application should be Andrews Reach Phases I and 11, not just Phase 11. 9. Since the plans submitted on September 22, 2005, only show Phase II, the approved plan set for this permit will have to include the previously approved plans for Phase I. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to January 3, 2006, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A. Please reference the State assigned project number on all correspondence. Any original documents that need to be revised have been sent to the engineer or agent. All original documents must be returned or new originals must be provided. Copies are not acceptable. If you have any questions concerning this matter please feel free to call me at (910) 796-7404.

REC7, �1. ,T SEP 22 C"U"i Re: Andrew's Reach Stonnwater Permit Application Dear Linda, Enclosed please find applications, plans, and calculations for the reference project. The project is located within the Eastern Wilmington City limits and proposes to construct 18 multifamily condominiums on approximately 2 acres of land. Stormwater will be collected and detained in a City detention pond and drawndown into 1600 linear feet of existing 36" perforated plastic pipe infiltration trench in Phase I. 0 SG ¢14— Accordingly, we propose to modify the existing permit for this 36" CPI' (SW8-05ft" to allow for the proposed development. The original pennit contained an allowance for 34,000 square feet of impervious within the condo site and was labeled then as "future Development." The current impervious proposal exceeds that amount by approximately 8,000 square feet. To mitigate the situation, we propose to provide infiltration capacity by detaining the required first 1 %:" of runoff in the City pond below the overflow slot. This volume would be drawndown via a PVC orifice over 2-5 days and routed through the existing 36" CPP trench for treatement. All other runoff would be discharged from the pond into an adjacent ditch. Please note on the plans that the drawdown orifice is directly piped to the existing system in Phase I which guarantees that the required runoff reaches the trench system. This method of treatment is identical to that utilized in the original permit. Please consider this application for review in hopeful issuance of a stormwater management permit such that we may trove forward towards construction. Please don't hesitate to call me with any questions or comments. Best Regards, Zak Shipman, E.I. Stroud Engineering, P.A. Altachntents wzs/zs F:/master/pw476/wpd/ph2stormcover. doc 107 COMMERCE ST.

Department of Housing and Urban Development, the Federal Home Loan Mortgage Corporation, Government National Mortgage Corporation, or the Federal National Mortgage Association, requesting or suggesting an amendment necessary to comply with the requirements of such corporation or agency shall be sufficient evidence of the approval of such corporation or agency, provided that the changes made substantially conform to such request or suggestion. Notwithstanding anything else herein to the contrary, only the Declarant, during the Developer Control Period, shall be entitled to amend this Declaration pursuant to this Section 4, F. ARTICLE VI. USE RESTRICTIONS AND ARCHITECTURAL CONTROL SECTION 1. Building and Site Improvement. No dwelling, wall or other structure, including fences, shall be commenced, erected, or maintained upon any Lot, nor shall any exterior addition to or change in or alteration therein (including painting or repainting of exterior surfaces) be made until the plans and specifications showing the nature, kind, shape, heights, materials, colors and location of the same shall have been submitted to and approved in writing as to harmony of external design and location in relation to surrounding structures and topography by the Declarant, or its designee, or, after the sale of all Lots by Declarant, by the Board of Directors of the Association, or by an Architectural Control Committee composed of three (3) or more representatives appointed by the Board. In the event the Declarant, or its designee, or, if applicable, the Board, or the Architectural Control Committee, fails to approve or disapprove such design and location within thirty (30) days after said plans and specifications have been submitted to it, approval will not be required and this Article will be deemed to have been fully complied with. Refusal or approval of any such plans, location or specification may be based upon any ground, including purely aesthetic mid environmental considerations, that in the sole and uncontrolled discretion of the Declarant, the Board, or Architectural Control Committee shall be deemed sufficient. One copy of all plans and related data shall be furnished to the Declarant, the Board, or Architectural Control Committee, as the case may be, for its records. Neither the Declarant, the Board, nor the Architectural Control Committee shall be responsible for any structural or other defects in plans and specifications submitted to it or any structure erected according to such plans and specifications. SECTION 2. Approval of Plans. No house plans will be approved unless the proposed house shall have a minimum of 2,500 square feet of enclosed, heated dwelling area. The term "enclosed, heated dwelling area" as used in the minimum requirements shall be the total enclosed area within a dwelling which is heated by a common heating system; provided, however, that such term does not include garages, terraces, decks, open porches, and like areas. B. Since the establishment of inflexible building setback lines for location of houses on lots tends to force construction of houses directly to the side of other homes with detrimental effects on privacy, view, preservation of important trees and other vegetation, ecological and related considerations, no specific setback lines shall be established by this Declaration. In order to assure, however, that the foregoing considerations are given maximum effect, the site and location of any house or dwelling or other structure upon any lot shall be controlled by and must be approved absolutely by the Declarant, the Board, or the Architectural Control Committee, as the case may be. C. The exterior of all houses and other structures must be completed within twelve (12) months after the construction of same shall have commenced, except where such completion is impossible or would result in great hardship to the Owner or builder, due to strikes, fires, national emergency or natural calamities. D. No structure shall be erected, altered, placed or permitted to remain on any Lot, except one single family dwelling not to exceed two and one-half stories in height. No garage apartments are allowed. E. All service utilities, fuel tanks, and wood piles are to be enclosed within a wall or plant screen of a type and size approved by the Declarant, the Board or the Architectural Control Committee, so as to preclude the same from causing an unsightly view from any highway, street or way within the subdivision, or from any other residence within the subdivision. All mail and newspaper boxes shall be uniform in design. Design for mail and newspaper boxes shall be furnished by Declarant. Fences shall be permitted on any Lot; provided, however, that the design and materials of any fence are approved by the Declarant, the Board, or the Architectural Control Committee, as the case may be, and provided further, that no fence shall be over six feet in height or forward of the rear corner of the house or dwelling erected on the Lot. Clothes lines are not permitted on any Lot. Of f street parking for not less than two (2) passenger automobiles must be provided on each Lot prior to the occupancy of any dwelling constructed on said Lot which parking areas and the driveways thereto shall be constructed of concrete, brick, asphalt, or turf stone, or any other material approved by Declarant, the Board or Architectural Control Committee. SECTION 3. Land Use and Building Tyne. No Lot shall be used for any purpose except for residential purposes. All numbered Lots are restricted for construction of single family dwellings only. Different and amended land use restrictions and architectural control guidelines may be established for Additional Property added to the Development by Declarant; provided, however, that no Lot may be used for other than single family dwellings except pursuant to approval of the Members in accordance with this Declaration. SECTION 4. Nuisances. No noxious or offensive activity shall be carried on upon any Lot, nor shall anything be done thereon which may be or may become an annoyance or nuisance to the neighborhood. There shall not be maintained any plants or animals, nor device or thing of any sort whose normal activities or existence are in any way noxious, dangerous, unsightly, unpleasant or other nature as may diminish or destroy the enjoyment of other Lots by the Owners thereof. It shall be the responsibility of each Owner to prevent the development of any unclean, unsightly or unkept condition of buildings or grounds on the Owner's Lot which would tend to substantially decrease the beauty of the neighborhood as a whole or the specific area. SECTION 5. Lot Maintenance. Each Lot Owner shall keep his Lot free from weeds, underbrush or refuse piles, or unsightly growth or objects. In the event the Owner fails to do so, then, alter thirty days notice from the Architectural Control Committee, the Association or its designee may enter upon the Lot and remove the same at the expense of the Owner, and such entry shall not be deemed a trespass, and in such event a lien shall arise and be created in favor of the Association for the full amount of the cost thereof chargeable to such Lot, including collection costs and such amounts shall be due and payable within thirty (30) days after the Owner is billed therefor. Such lien shall be enforceable by Court proceedings as provided by law for enforcement of liens. SECTION 6. Temporary Structures. No structure of a temporary character, trailer, basement, tent, shack, garage, barn or other outbuilding shall be used on any Lot any time as a residence either temporarily or permanently without the written consent of the Association or its designee; provided, however, that this shall not prevent the Declarant, its designees or assigns from maintaining a construction trailer or office on any part of the Development until the construction of dwellings on all Lots is completed. Provided that any temporary structure must comply with all governmental laws regulations whether state or local pertaining to said structures. However, nothing herein shall be meant to prevent the construction (with Developer's consent) of'storage and utility buildings. It is the express intention of the Developer that no trailer or mobile home (including a double -wide mobile home) shall be allowed on said property. Nothing herein shall be construed to prevent the use, upon Developer's approval, as set forth above, of a prefabricated or modular home as long as same is consistent with the general development and the standards of quality of said subdivision and is not materially detrimental to the value of the subdivided lots in said subdivision. SECTION 7. Vehicles/Boats. No boat, motor boat, camper, school bus, trailer, motor or mobile homes, tractor/trailer, (including vehicles rated to handle over one ton) or similar type vehicle, shall be permitted to remain on any Lot or on any street at any time, without the written consent of the Association or its designee.

The Association shall have the right to have all such vehicles towed away at the owner's expense.

Due to noise concerns, safety, liability and property damage reasons, no motorized, gas or electric vehicles, including dirt bikes and all terrain vehicles (ATV's) are permitted on the Common Area/Open Space or grounds of the properties or on lots yet to be built on. Only maintenance equipment needed to maintain the grounds is exempt from this rule. SECTION 8. Animals. No animals, livestock or poultry of any kind shall be kept or 10 I maintained on any Lot or in any dwelling except that dogs, cats or other household pets may be kept or maintained provided that they are not kept or maintained for commercial purposes and do not exceed three (3) pets in one household, and provided further that they are not allowed to run free, are at all times kept properly leashed or under the rule of their owner and do not become a nuisance to the neighborhood. SECTION 9. Statuary, Television Satellite Dishes and Antennas. No yard statuary or TV satellite signal receiving dishes are permitted on any Lot and no outside radio or television antennas shall be erected on any Lot or dwelling unit unless and until permission for the same has been granted by the Board of Directors of the Association or its Architectural Control Committee. Provided, however, an owner may install a satellite dish not exceeding 24 inches without further approval provided said satellite dish is installed in the rear portion of the yard or the rear portion of the dwelling. SECTION 10. Exterior Lights. All light bulbs or other lights installed in any fixture located on the exterior of any building or any Lot for the purpose of illumination shall be clear, white or non -frost lights or bulbs. SECTION 11. Landscaping. Prior to initial occupancy of the residence constructed on each Lot, the front yard area of such Lot must be sodded; provided, however, that any areas to be used as planting beds for trees and shrubs need not be sodded so long as such beds are planted prior to initial occupancy of the Lot. The Declarant, the Board or the Architectural Control Committee, as the case may be, may on account of adverse weather conditions or for other good cause shown permit such landscaping to be done within a period of six months after initial occupancy of the residence. SECTION 12. Signs. Except for lots upon which are located model homes constructed by builders approved by the Declarant, no signs of any type or description shall be placed on or displayed on any residential lot except signs "For Rent" or "For Sale," which signs shall not exceed six square feet in size.

Notwithstanding any language to the contrary, builders may erect in common areas temporary directional signs or signage not larger than ten square feet in size. SECTION 13. Alterations. No person shall undertake, cause, or allow any alteration or construction in or upon any portion of the Common Areas except the direction or with the express written consent of the Association. SECTION 15. Subdividing. Subject to the provisions of Article V hereof, no Lot shall be subdivided, or its boundary lines changed except with the prior written consent of the Declarant during the period of Declarant control of the Association and thereafter by the Board of Directors of the Association.
