The following planning and design standards shall be complied with and
no higher standard may be required by the Planning Board except where it finds
that because of exceptional and unique conditions of topography, location,
shape, size, drainage or other physical features of the site, or because of
the special nature and character of surrounding development, the minimum standards
specified herein would not reasonably protect or provide for public health,
safety, or welfare. Any higher standard required shall be reasonable and shall
be limited to the minimum additional improvements necessary to protect the
public health, safety, or welfare.
Reasonable requirements for the preservation of outstanding natural
features may be specified. These include large trees or groves, water courses
and falls, historic spots, exceptional views, and similar irreplaceable assets
in which there is general public interest.
