Minimum yards are established in most Zoning Ordinances in
order to secure healthy, attractive, and safe
neighborhoods. Permitting minimum lot sizes to be inundated
with floodplain water is counter productive to the
establishment of such yards, and has been subject to
continuing drainage and associated complaints from residents
with homes in such areas. It should be noted in subdivision
design that up 25% of any residential lot area may be
floodplain; however, no dwelling is permitted any closer
than twenty-five feet in horizontal distance to the edge of
an established floodplain (Section 2-412). The proposed
text amendment would require that floodplains – those lands
subject to inundation by the 100 year flood - be placed in
common open space when such open space is required by
Ordinance. Open space is required for conventional
subdivisions of 25 or more lots (Section 2-406.2); thus,
this amendment focuses on such subdivisions.
The
suggested changes are as follows:
2-406 Open Space Requirements
[Subsections 1 – 3 Same]
4. In the approval of a cluster subdivision or a
conventional subdivision of twenty-five or more lots in the
RR-2, R-1, R-2, R-3, and R-4 Districts, in no case
shall the applicable regulations or use limitations for the
district be modified or changed, nor shall any lot extend
into an estimated floodplain area. unless approved by the
Commission based on the determination that:
A. The particular floodplain, by reason of its size or
shape, has no
particular open space value, and
B. The lot, exclusive of floodplain, contains
seventy-five (75)
percent of the required minimum lot area specified for
the
district in which located.
[Subsections
5 and 6 Same]
