A copy of the recorded deed restrictions limiting the BUA on each lot; c. Verification that the permitted maximum built -upon area per lot has not been exceeded; d. A copy of the recorded subdivision plat(s) documenting the number of lots and the locations of all required drainage and maintenance access easements as depicted on the approved plans; e. Verification that more than 50% of the lots have been conveyed to individuals.

Design Summary, Page 2 of 2 Permit Number: (to be p ovided by DWQ) Drainage Area Number: Wet Detention Basin Operation and Maintenance Agreement I will keep a maintenance record on this BMP. 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. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): ❑ does ❑ does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ❑ does not incorporate pretreatment other than a forebay. 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 u on request. P q VE Inspection activities shall be performed as follows.

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. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): ❑ does ❑ does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ❑ does not incorporate pretreatment other than a forebay. 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. ., M :rM ��W �yy .1=.F�.vp Inspection activities shall be performed as follows.

The project had been inspected on August 9, 2018, and was found to not be in compliance due to the standing water in the small infiltration basin (DA-H). Since then Hurricane Florence came through and it continued to rain, so the Division had to delay the inspection to get a stretch of dry weather, and to allow sufficient time for the SCM's to be restored to design condition. All basins and ponds appear to be in compliance as of the date of this report.
