WMCPA - WATERSHED MANAGEMENT CONSTRUCTION PLAN APPROVAL
15A NCAC28.0233 - Due to the location of this project, it should be noted that a rule to protect and maintain
existing buffers along watercourses in all of Wake County became effective in 2006. The Neuse River Riparian
Area Protection and Maintenance Rule applies to all perennial and intermittent streams, lakes, ponds and
estuaries in Wake County with forest vegetation on the adjacent land or "riparian area". In riparian areas with
existing forest vegetation in the first 30 feet directly adjacent to the stream, the rule prohibits land disturbance,
®
17.
new development and fertilizer use within the first 50 feet of land next to the water. In riparian areas with
forest vegetation that is less than 30 feet wide, the rule prohibits land disturbance, new development and
fertilizer use within the area that contains forest vegetation (but not the entire 50 foot riparian area). For more
information about this riparian area rule, please contact the Division of Water Quality's Wetland/401 Unit at
919-807-6300. Wake County enforces the Neuse Buffer Rules in both the Cape Fear River Basin and the Neuse
River Basin except when superseded by the Jordan Buffer Rules[15A NCAC 02B.0265].
Wake County Watershed Management Section is not responsible for subject approvals of other Local, State or Federal Agencies. The
subject approvals are (but not limited to) Federal Emergency Management Area Flood regulations/requirements, Division of Water
Quality under stormwater or other water quality regulations/requirements, U.S. Army Corps of Engineers under Article 404/401
(Wetlands/Streams) jurisdiction/requirements, and/or any Federal, State, County and Local municipal regulations or permit
requirements. The approval issued in this letter cannot supersede any other required permit or approval.
