Flood Hazard Areas?
There are two main areas in Westchester that are in the 100-year floodplain. The northern area of town is in the 100-year floodplain for Addison Creek.  There is another 100-year flood plain area on the south end of town that is tributary to Salt Creek.  This area runs roughly west to east a few blocks north of 31st Street. The storms that have occurred that cause flooding to occur are generally storms that produce a lot of rain. For example, the main event in July of 2010 that caused Addison Creek and Salt Creek to overflow their banks was over seven inches of rain in a 12 hour period. Flooding has occurred along each of the creeks in 2006, 2008, and 2010.
