I, ('IcdAe, 4, k. r , 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 lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5.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 allowable built -upon area per lot is 7 Z square feet. This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools.

We find the plan to be acceptable with modifications and hereby issue this letter of Approval With Modifications. The Modifications Required for Approval are listed on the attached page. This plan approval shall expire three (3) years following the date of approval, if no land -disturbing activity has been undertaken, as is required by Title 15A NCAC 4B .0129. Please be advised that Title 15A NCAC 4B .01 18(a) requires that a copy of the approved erosion control plan be on file at the job site. Also, you should consider this letter to give the Notice required by G.S. 113A-61.1(a) of our right of periodic inspection to insure compliance with the approved plan. North Carolina's Sedimentation Pollution Control Program is performance -oriented, requiring protection of existing natural resources and adjoining properties. If, following the commencement of this project, it is determined that the erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation Pollution Control Act of 1973 (North Carolina General Statute 113A-51 through 66), this office may require revisions to the plan and implementation of the revisions to insure compliance with the Act. Fayetteville Regional Office 225 Green Street— Suite 714, Fayetteville, North Carolina 28301 • Phone: 910-433-3300 / FAX: 910-486-0707 Letter of Approval with Modifications Kirby Holding Group, LLC May 27, 2008 Page 2 of 4 The developer is responsible for obtaining any and all permits and approvals necessary for the development of this project prior to the commencement of this land disturbing activity. This could include agencies such as the Division of Water Quality's stonnwater regulations, their enforcement requirements within Section 401 of the Clean Water Act, the Environmental Protection Agency and/or the U.S. Anny Corps of Engineers' jurisdiction of Section 404 of the Clean Water Act, the Division of Solid Waste Management's landfill regulations, local County or Municipalities' ordinances, or others that may be required. This approval cannot supersede any other permit or approval; however, in the case of a Cease and Desist Order from the Corps of Engineers, that Order would only apply to wetland areas. All upland areas would still have to be in compliance with the N.C. Sedimentation Pollution Control Act. If any area on site falls within the jurisdiction of Section 401 or 404 of the Clean Water Act, the developer is responsible for compliance with the requirements of the Division of Water Quality, the Corps of Engineers and the Environmental Protection Agency (EPA) respectively. Any erosion control measures that fall within jurisdictional wetland areas must be approved by the aforementioned agencies prior to installation. The Land Quality Section must be notified of a relocation of the measures in question to the transition point between the wetlands and the uplands to assure that the migration of sediment will not occur. If that relocation presents a problem or contradicts any requirements of either DWQ, the Corps, or the EPA, it is the responsibility of the developer to inform the Land Quality Section regional office so that an adequate contingency plan can be made to assure sufficient erosion control remains on site. Failure to do so will be considered a violation of this approval. Please be aware that your project will be covered by the enclosed NPDES General Stormwater Permit NCGO1000 (Construction Activities). You should first become familiar with all of the requirements for compliance with the enclosed general permit. Please note that this approval is based in part on the accuracy of the information provided in the Financial Responsibility Form, which you have provided. You are requested to file an amended form if there is any change in the information included on the form. In addition, it would be helpful if you notify this office of the proposed starting date for this project. Please notify us if you plan to have a preconstruction conference.

Kirby: Recently you were sent a letter from the Division of Land Resources (DLR) regarding approval of vour Sedimentation and Erosion Control Plan for the subject development project. Accompanying the DLR letter was a National Pollutant Discharge Elimination System (NPDES) General Stormwater Permit No. NCG010000. That permit authorizes you to discharge stormwater to the surface waters of North Carolina. Those point source discharges are associated with activities such as clearing, grading; and other land disturbing and construction activities. The purpose of this letter is to draw your attention to and to stress the importance of that NPDES General Stormwater Permit. The requirements contained in the stormwater permit coupled with the requirements called for by the Division of Land Resources are vitally important to the protection of the waters of the State. If you have not already done so, you are urged to immediately read and adhere to the stormwater permit requirements contained there in. Of particular importance are Parts 1 and 11 of the permit. Parts I and 11 set forth the minimum visual monitoring and reporting requirements for your stormwater discharge. In particular, Part 1, Section B describes the visual monitoring frequencies and locations, the requirement to maintain a rain gauge onsite, and the need to maintain a written record of all inspections. Upon commencement of your land disturbing activity, you must initiate the visual monitoring and record keeping requirements as called for in the permit. The visual monitoring data results, along with all other permit required records must be maintained on -site and made available to Division of Water Quality representatives upon request and/or during upcoming inspections. The remaining parts of the Permit set forth definitions, general conditions and special conditions applicable to stormwater discharge(s). The conditions include special reporting requirements in the event of noncompliance, bypasses, treatment unit/process failures, etc. Noo7nhCarolina vlltut-ally North Carolina Division of Water Quality 225 Green Street - Suite 714 Fayetteville, NC 28301-5043 Phone (910) 433-3300 Customer Service Internet: h2o.enr.state .nc.us 17AX (910)496-0707 1-877-623-6749 An Equal Opportunity/Affirmative Action Employer - 50% Recycled110% Post Consumer Paper Matthew S.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important operation and maintenance procedures: — Immediately after the bioretention cell is established, the plants will be watered twice weekly if needed until the plants become established (commonly six weeks). — Snow, mulch or any other material will NEVER be piled on the surface of the bioretention cell. — Heavy equipment will NEVER be driven over the bioretention cell. — Special care will be taken to prevent sediment from entering the bioretention cell. — Once a year, a soil test of the soil media will be conducted. After the bioretention cell is established, I will inspect it once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: The entire BMP The perimeter of the bioretention cell Potential problems: Trash/debris is present.
