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 parts 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 This permit shall be effective from the date of issuance until rescinded and shall be subject to the following specified conditions and limitations. The permit issued shall continue in force and effect until the permittee files a request with the Division for a permit modification, transfer, 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 15A NCAC 2H.1000 and NCGS 143-215.1 et.al. 1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 405,908 square feet. The BUA requirements and allocations for this project are as follows: a. LOW DENSITY AREA BUA LIMITS. The low density area must not exceed 12% per the requirements of the stormwater rules. Within this low density area, this permit approves a percent BUA of 2% and the construction of a total of 405,908 square feet of BUA. This permit does not provide any allocation of BUA for future development within this low density area. 2. PERVIOUS AREA IMPROVEMENTS. The following types of improvements are included in the project and considered pervious per the stormwater rules: a. SOLAR FARM. In order for the solar panels to be considered a pervious surface, all of the recommendations of Chapter E-4 of the Stormwater Design Manual must be met. This project will provide horizontal gaps between individual modules on the panel, which allows the disconnection length to be no less than 80% of the panel width. Page 1 of 5 Post-Construction Stormwater Management Permit No. SW5240602 3. LOW DENSITY AREA REQUIREMENTS. The low density area requirements for this project are as follows: a. LOW DENSITY AND CONVEYANCE DESIGN. The low density area is permitted based on the design criteria presented in the sealed, signed and dated supplement and as shown in the approved plans and specifications. This low density area and conveyances must be provided and maintained at the design condition. b. PIPING. Other than the piping shown on the approved plans, only minimal amounts of piping under driveways and roads is allowed within the low density area when it cannot be avoided. No additional piping is allowed. c. DISPERSED FLOW. The low density area has maximized dispersed flow of stormwater runoff through vegetated areas and minimized the channelization of flow. d. VEGETATED CONVEYANCES. 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. 4. STORMWATER OUTLETS. This project does not propose any discharge points and therefore will not have the opportunity to cause erosion during the 10-year storm event. 5. VEGETATED SETBACKS. A 30-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. b. RELEASE OF STORMWATER NOT TREATED IN A STORMWATER CONTROL MEASURE (SCM). Stormwater that is not treated in an SCM, such as in this low density project (including roof drains), 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: a. EASEMENTS. All 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. As the property owner, Sidney Griffin, 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. 7.
