OF THE VILLAGE CODE OF MOUNT PROSPECT

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 amended 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 1 OO-year frequency flood. The SFHAs of the Village
are generally identified as such for the Des Plaines River, 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 170131 C panels 0202J, 0203J,
0204J, 0206J, 0207J, 0208J, 0209J, 0211J, 0212J, 0214J and 0216J dated August 19, 2008.
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 0209J, 0212J and 0214J of the countywide Flood Insurance Rate Map
prepared for Cook County by FEMA and dated August 19, 2008.
"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 1 OO-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, 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 170131 C panels 0202J, 0203J, 0204J, 0206J, 0207J,
0208J, 0209J, 0211J, 0212J, 0214J and 0216J dated August 19, 2008. 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.
SECTION TWO: That Section 22.105, "Base Flood Elevation" of Chapter 22 of the Village
Code of Mount Prospect as amended shall be further amended by deleting items A. and B. in
their entirety and inserting new items A. and B., which shall be and read as follows:
