This link will take you to the FEMA Map Service Center site. To view the Lake County preliminary Flood Insurance Rate Maps (FIRMs), choose "State" and "County" from the dropdown boxes, then click on "Get Preliminary FEMA map products". Then, to view the index map, choose the PDF labeled "18089CIND0B", at the bottom of the FIRM section. Determine the FIRM panel number and choose that PDF to view the preliminary FIRM. Please note that you will likely need to scroll down and expand the “Preliminary Products issued on 12/20/2013 for Lake County, Indiana” to find the appropriate FIRM.
You can also view the new floodplain maps using the Indiana Floodplain Information Portal. Under "Layers" on the menu, you can choose "Floodplains (Effective)" for the current maps, and "Floodplains (Preliminary)" for the new maps.
