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 Topsail Island Yacht Club Beach House Yacht Club — Clubhouse & Pool 111 North New River Drive, Surf City, Pender County FOR THE construction, operation and maintenance of one (1) infiltration trench in compliance with the provisions of Session Law 2008-211, effective October 1, 2008 and 15A NCAC 2H 1000, effective September 1, 1995 (hereafter collectively and separately referred to as the "stormwater rules') and the approved stormwater management plans and specifications and other supporting data as attached and 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 March 19, 2030, and shall be subject to the following specified conditions and limitations I DESIGN STANDARDS 1 This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data 2 The infiltration trench permitted for this facility was originally permitted under State Stormwater Permit Number SW8 990325 on October 30, 2001 A level spreader and vegetated filter strip were not required by that permit The same trench is re -permitted under this permit, and so the level spreader and vegetated filter strip are not required 3 The infiltration trench permitted for this facility was originally permitted under State Stormwater Permit Number SW8 990325 on October 30, 2001 A 50ft stormwater buffer was not permitted under that permit, and since the same trench is being re -permitted a stormwater buffer is not required under this permit However, this project may be subject to other Federal, State or Local requirements and if so this project must comply with those requirements All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements The final plats for the project will be recorded showing all such required easements, in accordance with the approved plans The runoff from all built -upon area within the permitted drainage area of this project must be directed into the permitted stormwater control system Page 1 of 5 State Stormwater Management Systems Permit No SW8 131011 This stormwater system has been approved for the management of stormwater runoff as described in Section 1 7 of this permit The stormwater control has been designed to handle the runoff described in Table 1 below Table 1 Impervious Area Subject to the 1995 Rule SW8 Future Development's Impervious Area 93,642 sf 990325 Restaurant on Corner Parcel's Impervious Area 27,870 sf SW8 Beach House Yacht Club's Impervious Area 66,000 sf 131011 Impervious Area in the Infiltration Trench Drainage Area ITDA 63,388 sf Allocated

to treat 63, 388sf of impervious area Of this amount, 62, 388sf of impervious area has been allocated for buildings, sidewalks and other uses as shown on the permitted plans and application form The future impervious area available inside the infiltration trench drainage area (ITDA) is 1,OOOsf The ITDA is labeled on the plans as `Drainage Area 1 Boundary" This 1, 000sf can be allocated at a future time via Plan Revision with no required change to the infiltration trench design There is also 2, 612sf of future impervious area that is available outside of the ITDA that can be permitted at a future time to be built under the 1995 rule and subject to a 1 5" design storm The 2, 612sf is a placeholder for future construction under the 1995 rule that can be permitted at a future date Construction of the 2,612sf of future impervious area outside 2, 612sf of impervious area at a future date Since this 2, 612sf of impervious area is permitted to be outside the infiltration trench's drainage area it does not drain to the current infiltration trench, and therefore cannot be treated by the current infiltration trench without modifying the current infiltration trench In order to use the 2, 612sf of impervious area at a future date the permittee may either modify the current trench to treat more impervious area (if the permittee later wants to construct the 2, 612sf inside the ITDA in the future), or the permittee may construct a second stormwater treatment device (if the permittee wants to continue with the plan to construct the 2, 612sf outside the ITDA in the future) The

protect is proposing 10,808 square feet of #57 stone laid at least four inches thick over a geotextile fabric as a pervious surface for a parking lot The underlying soil must not be mechanically compacted prior to installation If, in the future, this pervious surface is found to no longer meet SL 2015-149, a plan revision or modification will be required Any future areas of #57 stone proposed within this development will need prior approval from the Division in order to demonstrate that the improvements are still considered pervious under the latest definition of built -upon area II
