§ 34-913 — Floodplain buffer zone

Sec. 34-913. - Floodplain buffer zone.

(a) Floodplain buffer zones (FBZ) shall be established parallel to all floodplain preservation areas. The outer perimeter of each FBZ shall extend outward from the outer boundaries of the floodplain preservation area, based on the appropriate slope, in accordance with the following table: % Slope | 0-2.5 | >2.5-5.0 | >5.0-7.5 | >>7.5-10.0 | >10.0-12.5 | >12.5 Buffer Width (ft) | 60 | 70 | 80 | 90 | 100 | 100 The appropriate slope will be determined by taking the average slope of the first fifty (50) feet of buffer width from the floodplain preservation area. In no case shall the length over which the average is determined exceed three hundred (300) feet; and, in no event shall the buffer zone exceed the extent of the watershed. (b) No impervious cover will be allowed in the buffer zones except as outlined in subsection (c) below. (c) Construction activities in the buffer zones shall be restricted to the activities allowed in section 34-912.
