Whenever a lot containing "steep slopes," defined as slopes
with, minimally, a gradient of 15%, is proposed to be developed in
a single-family detached residential zone, the following requirements
shall apply.
The purpose of this article is to provide for reasonable control
of development within the steep slope areas of the Borough in order
to minimize the adverse impact caused by the development of such areas,
including, but not limited to, erosion, siltation, flooding, surface
water runoff, and pollution of potable water supplies from point and
nonpoint sources.
