MOUNT PROSPECT, COOK COUNTY, ILLINOIS ACTING IN THE EXERCISE OF THEIR
HOME RULE POWERS:
SECTION ONE: That Section 22.102, "Definitions" of Chapter 22 of the Village Code of Mount
Prospect, as amended, is hereby further by deleting the definitions of "Floodplain" and
"Regulatory Floodway" in their entirety and inserting new definitions of "Floodplain" and
"Regulatory Floodway," which shall be and read as follows:
"FLOODPLAIN": That land typically adjacent to a body of water with ground surface elevations
at or below the base flood or the 100-year frequency flood elevation. Floodplains may also
include detached special flood hazard areas, ponding areas, etc. The floodplain is also known
as the SFHA. The floodplains are those lands within the jurisdiction of the Village that are
subject to inundation by the base flood or 100-year frequency flood. The SFHAs of the Village
are generally identified as such for the Des Plaines River on the countywide Flood Insurance
Rate Map of Cook County prepared by FEMA on Map Number 170129 C panel 0207G date
April 16, 2007 and panel 0209F dated November 6, 2000. The SFHAs of the Village are also
generally identified as such for Feehanville Ditch, Higgins Creek, McDonald Creek, McDonald
Creek Tributary B and Weller Creek on the Cook County Flood Insurance Rate Map prepared
by FEMA on Map Number 170129 C panel(s) 0202F, 0204F, 0208F, 0209F, 0211F, 0212F,
0214F and 0216F dated November 6, 2000. The SFHAs of those parts of unincorporated Cook
County that are within the extraterritorial jurisdiction of the Village or that may be annexed into
the Village are generally identified as such on panel number 0209F, 0212F and 0214F the
countywide Flood Insurance Rate Map prepared for Cook County by FEMA and dated
November 6,2000.
"REGULATORY FLOODWAY": The channel, including on stream lakes and that portion of the
floodplain adjacent to a stream or watercourse, as designated by IDNR/OWR, which is needed
to store and convey the existing and anticipated future 100-year frequency flood discharge with
no more than a one-tenth foot (0.1') increase in stage due to the loss of flood conveyance or
storage, and no more than a ten per cent (10%) increase in velocity. The floodways are
designated for the Des Plaines River on the countywide Flood Insurance Rate Map of Cook
County prepared by FEMA on Map Number 170129C panel 0207G dated April 16, 2007. The
floodways are designated for Feehanville Ditch, McDonald Creek, McDonald Creek Tributary B
and Weller Creek on the Cook County Flood Insurance Rate Map prepared by FEMA on Map
Number 17129 C panel(s) 0208F, 0209F, 0212F and 0216F dated November 6, 2000. When
two f100dway maps exist for a waterway, the more restrictive floodway limit shall prevail. To
locate the regulatory floodway boundary on any site, the regulatory floodway boundary should
be scaled off the regulatory floodway map and located on the site plan using reference points
common to both maps. Where interpretation is needed to determine the exact location of the
regulatory floodway boundary, IDNR/OWR should be contacted for any interpretation.
