----------------------------Original message---------------------------- I have offered the duplicates I have of the USGS Illinois flood prone area maps to Illinois map libraries, but I still have some quads left. These are the black and white topo based maps done back in the 1970's predating the FEMA rate maps. There isn't a complete set left but some quads still have multiple copies. So the first respondants with mailing address will receive absolutely free a single copy of each quad left until they run out. I can also include an unmarked index map so that you can mark what you will own.
