The SCM requirements for this project are as follows: a. SCM DESIGN (2017 Rules). The SCMs identified as Pond 2 and Pond 3 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 (SL 2008-211). The SCM identified as Pond 1 is permitted based on the following design criteria and as shown in the approved plans and specifications. This SCM must be provided and maintained at the design condition. These SCMs must be provided and maintained at the design condition. c. POND DISCHARGE (SL 2008-211). A vegetated filter strip is not required for the discharge as the wet detention pond(s) has(have) been designed for a 90% total suspended solids removal efficiency. d. 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. e. FOUNTAINS (2017 Rules). At this time, a decorative spray fountain has not been proposed within Pond 2 and Pond 3. Decorative spray fountains will be allowed in the wet ponds 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. FOUNTAINS (SL 2008-211). Since the permanent pool volume is greater than 30,000 cubic feet, a decorative spray fountain will be allowed in Pond 1, subject to the following criteria: i. The fountain must draw its water from less than 2' below the permanent pool surface. ii. Separated units, where the nozzle, pump and intake are connected by tubing, may be used only if they draw water from the surface in the deepest part of the pond. iii. The falling water from the fountain must be centered in the pond, away from the shoreline. iv. The maximum horsepower for the fountain's pump is based on the permanent pool volume. The maximum pump power for a fountain in this pond is 1/2 horsepower. g. 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. 5. STORMWATER OUTLETS (2017 Rules). The peak flow from the 10-year storm event shall not cause erosion downslope of the discharge point. 6. STORMWATER OUTLETS (SL 20018-211). Stormwater runoff that is directed to flow through any wetlands shall flow into and through these wetlands at a non -erosive velocity. 7. VEGETATED SETBACKS (2017 Rules). 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.

Page 2 of 7 State Stormwater Management Permit No. SW8 160306 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. 8. VEGETATED BUFFERS (SL 2008-211). A 50-foot wide vegetative buffer must be provided and maintained in grass or other vegetation adjacent to all surface waters as shown on the approved plans.

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. Any problems that are found shall be repaired immediately. BMP element: Potential problem: How I will remediate the problem: The entire BMP Trash/debris is present. Remove the trash/debris.

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, James Yopp 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 ensure ongoing compliance with State Stormwater Management Permit Number S W8160306 Phase 2, 3, 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. 6. The maximum allowable built -upon area per lot is 3,500 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. OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following: 6. The maximum built -upon area per lot, in square feet, is as listed below. Lot # BUA Lot # BUA Lot # BUA Lot # BUA 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 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 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 swa/es 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.
