BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 1,355,336 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, and DA3 have been designed to handle the runoff from 231,630, 383,945, and 722,261 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, and DA3 is limited to 29,952, 43,856, and 21,300 square feet, respectively. This permit approves 17,500 square feet of BUA that was not able to be collected and treated in an SCM due to NCDOT right-of-way grading to bypass the system. Page 1 of 6 Post -Construction Stormwater Management Permit No. SW8 220809 b. BUA FOR INDIVIDUAL LOTS. Each of the 108 lots are limited to a maximum amount of BUA as indicated in Attachment B of this permit and 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. 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. c. 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. d. 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. 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 50-foot 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. 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 TREATED 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: Page 2 of 6 Post -Construction Stormwater Management Permit No. SW8 220809 a.

Important maintenance procedures: _ Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). _ No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. _ Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. _ If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected 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 should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.

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, D Logan , 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 ensur ongoing compliance with State Stormwater Management Permit Number,SlA)g V.Q090 , 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. 6. The maximum allowable built -upon area per lot is (see chart) 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 30** foot wide vegetated buffer between all impervious areas that do not drain to the permitted system and surface waters. **50 foot for projects located in the 20 coastal counties. 8. All runoff from the built -upon areas on the lot must drain into the penmitted 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 swa/es to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into t,',e system are not required to provide these additional measures.
