AMENDED (c) Subject to subsection (e), the existing natural vegetation in a designated 11-11-86 buffer area shall, not be disburbed in any way that would reduce the buffer area's effectiveness in achieving the objectives set forth in subsection (a).

However, the subdivider shall allocate to kt:- each lot a proportionate share of the total subdivision's impervious surface, and that allocafion shall be shown on the face of the subdivision plat. The amount of impervious surface so allocated shall be included in determining the maximum amount allowed under subsections (a) and (Jb) . •
