See website for details. 10-20-1 Minimum Standards - All soil erosion and sedimentation control plans and measures must conform to the minimum applicable standards specified in North Carolina's Erosion and Sediment Control Planning ❑ 20. and Design Manual and the Wake County Sedimentation and Erosion Control Plan Review Manual. Erosion control devices must be installed to prevent any offsite sedimentation for any construction site regardless of the size of the land disturbance. 10-20-3 Operation in Lakes or Natural Watercourses -Land disturbing activity in connection with ❑ 21 construction in, on, over, or under a lake of natural watercourse must minimize the extent and duration of disruption of the stream channel. Where relocation of a stream forms an essential part of the proposed activity, the relocation must minimize unnecessary changes in the stream flow characteristics. ❑ 22. 10-20-10 Standards for High Quality Water (HQW) Zones Land -disturbing activities to be conducted in High Quality Water Zones must be designed as follows: ❑ a' Uncovered areas in High Quality Water (HQW) zones must be limited at any time to a maximum total area of 20 acres within the boundaries of the tract. Maximum Peak Rate of Runoff - Erosion and sedimentation control measures, structures, and devices ❑ b. within HQW zones must be planned, designed and constructed to provide protection from the runoff of the 25-year storm. Settling Efficiency - Sediment basins within HQW zones must be designed and constructed so that the ❑ C. basin will have a settling efficiency of at least 70% for the 40 micron (0.04mm) size soil particle transported into the basin by the runoff of that 2-year storm which produces the maximum peak rate of runoff. Grade - The angle for side slopes must be sufficient to restrain accelerated erosion (side slopes no ❑ d' steeper than 2 horizontal to 1 vertical if a vegetative cover is used for stabilization unless soil conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices, structural devices or other acceptable ditch liners) ❑ 23 Senate Bill 1020; "SECTION 3.(h) Additional standards for land -disturbing activities in the water supply watershed": ❑ a' Erosion and sedimentation control measures, structures, and devices shall be planned, designed, and constructed to provide protection from the runoff of the 25-year storm Disapproval_WMConstructionPlanReviewChecklist-V.3_WM WAKE COUNTY I, ( ki�- — Wake County Environmental Services Department Water Quality Division, Watershed Management Section 336 Fayetteville St. • P.O.

Neuse Riparian Buffer Rules Due to the location of this project, it should be noted that a rule to protect and maintain existing buffers along watercourses in the Neuse River Basin became effective on July 22, 1997. The Neuse River Riparian ® Area Protection and Maintenance Rule (15A NCAC 213.0233) applies to all perennial and intermittent 24 streams, lakes, ponds and estuaries in the Neuse River Basin with forest vegetation on the adjacent land or "riparian area".
