Fisher Boulevard (US 421) and Riverfront Road, Kure Beach, New Hanover County FOR THE construction, operation and maintenance of one (1) infiltration basin in compliance with the provisions of Session Law 2008-211 and 15A NCAC 2H .1000 (hereafter 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 (hereafter referred to as the Division or DEMLR) and considered a part of this permit. This permit shall be effective from the date of issuance until May 14, 2022, 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. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.9 of this permit. The stormwater control has been designed to handle the runoff from 48,115 square feet of new impervious area. 3. The basin has been designed under the alternative design option to handle the 10 year 24 hour design storm without discharging, therefore neither an LSNFS nor an offline bypass are required, as indicated in Section 1.9 of this permit. 4. The drainage area of the infiltration basin will be limited to the amount of built -upon area indicated in Section 1.9 of this permit, and as shown on the approved plans. The built - upon area for the future development is limited to 0 square feet. 5. Phase 1 of this project contains an area of redeveloped built -upon surfaces, which is excluded from the State Stormwater permitting requirements under the following conditions: 1) The project must be constructed as shown on the approved plans submitted to this Office; 2) The proposed built -upon area of 82,827 square feet cannot exceed the existing built -upon area of 83,450 square feet; and, 3) The proposed stormwater controls, several small infiltration areas, must be constructed to provide equal protection of surface waters as the existing stormwater control, which is sheet flow to existing drainage ditches. Page 1 of 6 State Stormwater Management Systems Permit No. SW8 140503 6. Phase 2 of this project also contains an area of redeveloped built -upon surfaces, which is excluded from the State Stormwater permitting requirements under the following conditions: 1) The project must be constructed as shown on the approved plans submitted to this Office; 2) The total proposed built -upon area of 35,632 square feet cannot exceed the existing built -upon area of 35,632 square feet; and, 3) The proposed stormwater controls, vegetated sheet flow to existing drainage ditches, must be constructed to provide equal protection of surface waters as the existing stormwater control, which is vegetated sheet flow to existing drainage ditches. The 35,632 square feet of built -upon area allocated to this 2.5-acre project area includes 0 square feet of proposed built -upon area and 35,632 square feet of built -upon area allocated for future improvements. 7. The runoff from the 48,115 sf of built -upon area within the permitted infiltration basin drainage area of this project must be directed into the permitted stormwater control system. The remaining BUA is treated by small infiltration areas that are excluded from permitting subject to the redevelopment exclusion requirements. 8. This redevelopment project shall provide a minimum 30' wide vegetated buffer adjacent surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers, and the mean high water line of tidal waters. 9. The following design criteria have been permitted for the infiltration basin and must be provided and maintained at design condition: a. Drainage Area, acres: 2.48 Onsite, ft2: 108,187 Offsite, ft2: 0 b. Total Impervious Surfaces, ft2: 48,115 Onsite, ft2. 48,115 Offsite, ft2-0 c. Design Storm, inches: 1.5" d. Basin Depth, feet: 2.13 e. Bottom Elevation, FMSL: 10.67 f. Bottom Surface Area, ft2: 3,690 g. Bypass Weir Elevation, FMSL: 12.8 h. Permitted Storage Volume, ft3: 12,130 i. Predevelopment 1 yr 24 hr peak flow, cfs: n/a j. Post -development 1 yr 24 hr peak flow, cfs: n/a k. Type of Soil: Lakeland / Wakulla I. Expected Infiltration Rate, in/hr: 5.5 m. Seasonal High Water Table, FMSL: 8.67 n. Time to Draw Down, hours: <5 o. Receiving Stream/River Basin: Atlantic Ocean / CPF00 p. Stream Index Number: 99-(3) q. Classification of Water Body: "SB" 10. Per section .1008 (h) of the stormwater rules, this alternative design infiltration basin provides equal or better protection because it infiltrates a 10-year, 24-hour storm without discharging, using an infiltration rate of one-half of the expected infiltration rate provided in the soils report. The infiltration basin is designed in accordance with Option 4 of Section 16.3.9 of the BMP manual, therefore, no bypass, no vegetated filter strip, and no additional storage volume are required. The approved parameters are: a. 10 yr 24 hr design storm, inches 7.24 (from NOAA chart) b. Volume to infiltrate, cf: 29,390 c. Volume infiltrated in 24 hours, cf: 20,295 (at'/ expected infiltration rate) d. Remaining volume to infiltrate, cf: 9,095 (<12,130, OK) II.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public. and the removal efficiency of the BMP. Important maintenance procedures: - The drainage area will be carefully managed to reduce the sediment load to the infiltration basin. - Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). No portion of the infiltration basin will be fertilized after the initial fertilization that is required to establish the vegetation. The vegetation in and around the basin will be maintained at a height of approximately six inches. After the infiltration basin is established, it will be inspected once a quarter 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 will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: Potentialproblem: How I will remediate theproblem: The entire BMP Trash/debris is present. Remove the trash/debris.
