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,
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
