FEMA Floodplain Mapping
"Flood hazard areas" are defined as those areas within the Village that are adjacent to or near rivers and streams that have a 1% chance of being inundated by flood water in a given year as a result of rain events, rapid snow melt, and/or frozen ground conditions. The 1% chance of flooding condition is often referred to as the "base" or "regional" flood, but is most commonly known as the "100-year flood".
The geographic areas within a community that are affected by the 100-year Flood are shown on a map called the Flood Insurance Rate Map (FIRM) developed by the Federal Emergency Management Agency (FEMA). The floodplain map for the Village of Germantown is comprised of twelve (12) separate map panels that cover the entire Village.
