Building setback lines appropriate to the location and type
of development contemplated, which are more restrictive than required
in the applicable zoning district, may be permitted or required by
the Planning Commission and shall be shown on the final plat, condominium
plat, or certified survey map. Examples of the application of this
provision would include requiring greater setbacks on cul-de-sac lots
to achieve the necessary lot width at the setback line, requiring
greater setbacks to conform to setbacks of existing adjacent development,
requiring greater setbacks to avoid placing buildings within easements
or vision clearance triangles, setting special yard requirements to
protect natural resources, or requiring greater setbacks along arterial
streets and highways to meet the requirements of Chapter Trans 233
of the Wisconsin Administrative Code.
Where natural drainage channels, floodplains, wetlands, or other
environmentally sensitive areas are encompassed in whole or in part
within a proposed land division or condominium, the Planning Commission
may require that such areas be dedicated or that restriction be placed
on the plat or certified survey map to protect such resources. The
Planning Commission may further require that such areas be included
in outlots designated on the plat or certified survey map and restricted
from development.
