Description:
Abstract:
This set of 102 tiles depicts by county the 100 year and 500 year floodzones for the unincorporated areas as indicated on the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (FIRM) maps and Flood Hazard Boundary maps were digitized from paper maps. When digitizing, all RMS values were not more than twenty feet. The DBASE file FLOODPLA.DBF was also created and contains documentation on individual panels during the digitizing process. Mapscale: 1:6000 to 1:24,000

Purpose:
These data are appropriate for use in local and regional thematic analysis of floodzones in unincorporated areas of Illinois.

Supplemental_Information:
The path to these data sets is *path_name_suppressed*/fldzones where <county_name> should be replaced with the name of the county of interest. Longer county names have been truncated to eight characters.
