'The project shall be constructed, operated and maintained in accordance with these approved plans and specifications. The approved plans and specifications are incorporated by reference and are enforceable part of this permit. This permit shall be effective from the date of issuance until July 15, 2022 and shall be subject to the following specified conditions and limitations. The permit issued shall continue in force and effect until the permittee files a request with the Division for a permit modification, transfer, renewal, or rescission; however, these actions do not stay any condition_ The issuance of this permit does not prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A NCAC 2H.1000 and NCGS 143-215.1 et.al. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 716,855 square feet. The runoff from all BUA within the permitted high density drainage areas of this project must be directed into the permitted SCMs. The BUA requirements and allocations for this project are as follows: a. SCM BUA LIMITS. The SCMs labeled DA1, DA2, DA3, DA4, and DA5 have been designed to handle the runoff from 354,026; 71,989; 67,359; 139,712; and 75,969 square feet of BUA, respectively, within the delineated drainage areas. The BUA for future development within the drainage areas to the SCMs labeled DA1, DA2, DA3, DA4, and DA5 is limited to 14,200; 1,000; 2,950; 8,100; and 2,300 square feet, respectively. This permit approves 7,800 square feet of BUA that was not able to be collected and treated in an SCM due to NCDOT grading to bypass the system_ Page 1 of 7 Post -Construction Stormwater Management Permit No. SW8 220604 b. BUA FOR INDIVIDUAL LOTS. Each of the 121 lots are limited to a maximum of 3,800 square feet of BUA, as indicated in the approved plans and specifications. The maximum BUA assigned to each lot via this permit and the recorded deed restrictions and protective covenants may not be increased or decreased by either the individual lot owner or the permittee unless and until the permittee notifies the Division and obtains written approval from the Division. c. CAMA AECs. Where a project or lot is located within CAMA's Area of Environmental Concern (AEC), the Division of Coastal Management (DCM) may calculate a different maximum BUA based on CAMA regulations. The more restrictive BUA limit will apply to the project. 2. PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area improvements listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have been proposed for this project. Pervious area improvements will be allowed in this project if documentation is provided demonstrating those improvements meet the requirements of the stormwater rule. 3. SCM REQUIREMENTS. The SCM requirements for this project are as follows: a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the sealed, signed and dated supplement and as shown in the approved plans and specifications. These SCMs must be provided and maintained at the design condition. b. SCM DESIGN FOR SA WATER. The SCM(s) provide(s) runoff treatment for the difference between the pre- and post -development runoff volumes for the one-year, 24-hour storm event and have demonstrated that it is not feasible to meet the minimum design criteria for an infiltration system. The stormwater is filtered through a minimum of 18 inches of sand prior to discharge. The discharge is directed to a level spreader — filter strip and the excess runoff is released at a non -erosive velocity at the edge of the vegetated setback or to an existing stormwater drainage system. c. PLANTING PLAN. The SCM landscape planting plan shown in the approved plans shall be followed in its entirety during construction. After the plants are established, the operation and maintenance agreement must be followed. d. FOUNTAINS. At this time, a decorative spray fountain has not been proposed within the wet pond. Decorative spray fountains will be allowed in the wet pond if documentation is provided demonstrating that the proposed fountain will not cause resuspension of sediment within the pond or cause erosion of the pond side slopes_ e. IRRIGATION. If the wet pond is to be used for irrigation, it is recommended that some water be maintained in the permanent pool, the vegetated shelf is planted with appropriate species that can handle fluctuating conditions, and human health issues are addressed. f. PRETREATMENT. The following pretreatment device(s) has (have) been provided to prevent clogging in the infiltraion SCMs: sump in catch basin. g. SAND FILTER MEDIA MAINTENANCE: The sand filter shall be maintained in a manner that results in a drawdown of at least two inches per hour at that sand surface. 4. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause erosion downslope of the discharge point. 5. VEGETATED SETBACKS. A 50400t wide vegetative setback must be provided and maintained in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The setback is measured horizontally from the normal pool elevation of impounded structures, from the top of bank of each side of streams or rivers, and from the mean high waterline of tidal waters, perpendicular to the shoreline. Page 2 of 7 Post -Construction Stormwater Management Permit No. SW8 220604 a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback except as shown on the approved plans or in the following instances where the BUA has been minimized and channelizing runoff from the BUA is avoided: i. Water dependent structures; and ii. Minimal footprint uses such as poles, signs, utility appurtenances, and security lights that cannot practically be located elsewhere. b. RELEASE OF STORMWATER NOT TREAT ED IN AN SCM. Stormwater that is not treated in an SCM must be released at the edge of the vegetated setback and allowed to flow through the setback as dispersed flow. 6. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the following documents to be recorded with the Office of the Register of Deeds prior to the sale of individual lots or groups of lots: a. EASEMENTS. All SCMs, stormwater collection systems, vegetated conveyances, and maintenance access located on property owned by other persons or entities must be located in permanent recorded easements or drainage easements as shown on the approved plans. b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance agreement must be recorded with the Office of the Register of Deeds. c. FINAL PLATS. If a final plat is recorded, it must reference the operation and maintenance agreement and must also show all public rights -of -way, dedicated common areas, and/or permanent drainage easements, in accordance with the approved plans. d. DEED RESTRICTIONS AND PROTECTIVE COVENANTS. The permittee shall record deed restrictions and protective covenants prior to the issuance of a certificate of occupancy to ensure the permit conditions and the approved plans and specifications are maintained in perpetuity. Recorded deed restrictions and protective covenants must include, at a minimum, the following statements related to stormwater management: i. The following covenants are intended to ensure ongoing compliance with Stormwater Management Permit Number SW8 220604, as issued by the Division of Energy, Mineral and Land Resources (the "Division") under 15A NCAC 02H.1000, effective January 1, 2017. ii. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the Stormwater Management Permit. iii. These covenants are to run with the land and be binding on all persons and parties claiming under them. iv. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the Division. V. Alteration of the drainage as shown on the approved plans may not take place without the concurrence of the Division. vi. The maximum built -upon area (BUA) per lot is 3,800 square feet. This allotted amount includes any BUA 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 not shown on the approved plans. BUA has the same meaning as G.S. 143-214.7, as amended. vii. For those lots within the CAMA Area of Environmental Concern, where DCM calculates a different maximum lot BUA, the governing maximum lot BUA shall be the more restrictive of the two amounts. viii. The maximum allowable BUA shall not be exceeded on any lot until the permit is modified to ensure compliance with the stormwater rules, permit, and the approved plans and specifications. ix. All runoff from the BUA on the lot must drain into the permitted system. This may be accomplished via grading, a stormwater collection system and/or a vegetated conveyance. X. A 50-foot 50-foot wide vegetative setback must be provided and maintained adjacent to all surface waters in accordance with 15A NCAC 02H.1003(4) and the approved plans. xi.

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. 1, Bryant Spencer , 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: The following covenants are intended to ensue ongoing compliance with State Stormwater Management Permit Number Sul a�Ob 4 , as issued by the Division of Energy, Mineral and Land Resources under the Stormwater Management Regulations. 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 Energy, Mineral and Land Resources. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Energy, Mineral and Land Resources. m 1 c 1 6. The maximum allowable built -upon area per lot is5f'5 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. 7. Each lot will maintain a 50 foot wide vegetated buffer between all impervious areas and surface waters. 8. 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 e*�Vstem are not required to provide these additional measures. -^-, Signature: Date If S-9,0 -au Jl I, 1 Am W Arson , a Notary Public in the State of a t' , County of (bcur.svj1CX do hereby certify that personally appeared before me this the day of { Y �" ) 20 �� , and acknowledge the due execution of the foregoing instrument.
