MINERAL AND LAND RESOURCES STATE STORMWATER MANAGEMENT PERMIT LOW DENSITY DEVELOPMENT WITH A CURB OUTLET SWALE SYSTEM In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended, and other applicable Laws, Rules, and Regulations PERMISSION IS HEREBY GRANTED TO Dominion Land Corporation and Shiloh Holdings, LLC /Meek Earth Holdings, LLC Boiling Springs Lakes Commercial Tract NC Hwy 87, Brunswick County FOR THE construction, operation and maintenance of a 24%low density project with a curb outlet Swale system discharging to Class B-Sw waters in compliance with the provisions of Title 15A NCAC 2H .1000 effective January 1, 2017 (the "Stormwater rules") and the approved Stormwater management plans, application, supplement(s), specifications, and other supporting data (the "approved plans and specifications') as attached and/or on file with and approved by the Division of Energy, Mineral and Land Resources (the "Division" or "DEMLR") and considered an enforceable part of this permit. This permit shall be effective from the date of issuance until rescinded and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS 1. This permit is effective only with respect to the management of Stormwater described in the approved plans and specifications. The overall percent of built -upon area (BUA) permitted for the project must not exceed 24% per the requirements of the Stormwater rules. This permit covers the construction of a total of 134,383 square feet of BUA, which includes 50,705 square feet of proposed BUA and 84,178 square feet of future BUA allocation. The current design provides a total of 15%impervious area for the project. 2. Each commercial lot whose ownership is not retained by the permittee shall submit a separate low density Stormwater permit application to the Division and receive approval prior to construction. Prior to construction, the permittee shall ensure that the owner of the commercial lot has obtained the separate low density Stormwater management permit. 3. A 50-foot wide vegetative setback must be provided and maintained adjacent to all surface waters, 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 in accordance with the Stormwater rules and the approved plans and specifications. All Stormwater runoff, including roof drains, shall be released as dispersed flow no closer than at the edge of the vegetated setback. At no time shall Stormwater runoff be piped into or through the 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: a. Water dependent structures; and b. Minimal footprint uses such as poles, signs,. utility appurtenances, and security lights that cannot practically be located elsewhere. Page 1 of 5 State Stormwater Management Permit No. SW8 190905 4. This project has maximized dispersed flow of stormwater runoff through vegetated areas and minimized the channelization of flow. Stormwater runoff that could not be released as dispersed flow may be transported by vegetated conveyances with minimum side slopes of 3:1 (H:V) designed to not erode during the peak flow from the 10-year storm event as defined in the stormwater rules and approved by the Division. 5. This project proposes a curb outlet system. Each designated curb outlet must convey stormwater runoff to a vegetated conveyance or vegetated area as shown on the approved plans and specifications. The conveyance must be maintained with a dense vegetated cover at a minimum of 100' long, side slopes at 3:1 (H:� or flatter, a minimum bottom width of 2 feet, and a longitudinal slope no steeper than 5% in order to carry the peak flow from the 10-year storm at anon -erosive velocity 6. No piping shall be allowed except those minimum amounts necessary to direct stormwater runoff beneath a BUA such as a road or driveway when it cannot be avoided. 7. The peak flow from the 10-year storm event shall not cause erosion downslope of the stormwater outlet discharge point. II. SCHEDULE OF COMPLIANCE The project shall be constructed, operated and maintained in accordance with the conditions of this permit and the approved. plans and specifications. 2. Curb outlet swales, vegetated areas and vegetated conveyances shall be entirely constructed, vegetated, and operational prior to the construction of any development, per the approved plans and specifications. 3. During construction, erosion shall be kept to a minimum and any eroded areas of the on -site stormwater system will be repaired immediately. 4. All vegetated conveyance systems, stormwater collection systems, and/or maintenance accesses must be located in public rights -of -way, dedicated common areas that extend to the nearest public right-of-way, and/or permanent recorded easements that extend to the nearest public right-of-way for the purpose of inspection, operation, maintenance, and repair. 5. The permittee shall provide and perform the operation and maintenance necessary, as listed in the signed Operation and Maintenance Agreement titled Swale System Maintenance Requirements to assure that the permitted curb outlet swales and vegetated conveyance system functions at the approved design condition. The approved Operation and Maintenance Agreement is incorporated by reference into this permit and must be followed in its entirety and maintenance must occur at the scheduled intervals. 6. The operation and maintenance agreement must be recorded with the Office of the Register of Deeds. 7. Records of maintenance activities must be kept and made available upon request to authorized personnel of the Division. The records will indicate the date, activity, name of person performing the work and what actions were taken. 8. The final plats for the proiect must be recorded with the Office of the Register of Deeds. The recorded plat 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. 9. 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. 10. The permittee is responsible for verifying that the proposed built -upon area for the entire project does not exceed the maximum allowed by this permit. Page 2 of 5 State Stormwater Management Permit No. SW8 190905 11. Upon completion of the project, the permittee shall determine whether or not the project is in compliance with the permitted plans and take the necessary following actions: a.
