FLOOD IMPACT CATERGORIES
The flood categories used in the NWS are:
MINOR - minimal or no property damage, but possibly some public threat.
MODERATE - some inundation of structures and roads near streams. Some evacuations of people and/or transfer of property to higher elevations.
MAJOR - extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations.
RECORD - flooding which equals or exceeds the highest stage or discharge at a given site during the period of record keeping. For the City of Evansville and Vanderburgh County that event was January 1937 flood.
A rapid and extreme flow of high water into a normally dry area, or a rapid water level rise in a stream or creek above a predetermined flood level, beginning within six hours of the causative event (e.g., intense rainfall). However, the actual time threshold may vary in different parts of the country. Ongoing flooding can intensify to flash flooding in cases where intense rainfall results in a rapid surge of rising flood waters.

You will not be ordered to evacuate unless there is a real threat to your well-being, or you might become stranded where help could not reach you. Don't second guess government and emergency officials. When you are told to evacuate, please do so immediately. Your safety, and the safety of others, depends on following instructions. Evacuation saves lives.
The Evacuation routes are the same as the Snow Routes in the City and County. http://www.evansville.in.gov/Modules/ShowDocument.aspx?documentid=2922
