Check your flood exposure using online flood hazard maps
"These hazard maps are indicative inundation maps for large flood events and useful only for knowing where not to be during extremely heavy rainfall. For local governments, these flood hazard maps can be used for localized emergency response (i.e. evacuation and access routes, road closures, siting of key rescue facilities) and for urban planning."
