or structure be erected, constructed or substantially enlarged unless
and until it can be demonstrated by information, plans and studies
furnished by an applicant that the following requirements can be met.
No subdivision or site plan shall be approved

Within any area containing slopes of 20% or
greater, no subdivision shall be created, no site plan shall be approved,
and no land disturbance shall be permitted, except in conformance
with the following regulations:
A. All slopes of 20% or greater located on a tract of
land shall be protected from disturbance and preserved in a natural
state, except as provided hereafter.
B. All areas of a tract of land containing slopes of 20% or greater shall be delineated on a plan showing the proposed site plan, subdivision or land disturbance. Slope delineation shall be in accordance with §
113-112 of this Part
3.
C. A twenty-five-foot slope transition buffer shall be
established from the edge of delineated slopes of 20% or greater.
No structure, parking area or private drive may be located within
this buffer. Construction activities permitted within this buffer
shall be limited to grading incidental to an approved land disturbance,
site development, installation of on-site septic systems and installation
of on-site potable water supply systems.
D. Roadways shall be designed to follow natural terrain.
Natural slopes of 20% or greater shall not be disturbed for new road
construction. On all slopes greater than 15%, the maximum horizontal
distance of disturbance associated with new road construction shall
not exceed 75 feet in width.
E. At the Planning Board's discretion, slopes of 20%
or greater and slope transition buffers may be disturbed, provided
that the slope of 20% or greater is man-made or represents an isolated
topographic condition, the destruction of which will not result in
significant modification to the drainage capabilities or visual character
of the property. Such disturbance shall be limited to no more than
1,000 square feet, although the Board may grant further relief if
special circumstances warrant further consideration.
