Flood Information & Preparedness

Being 'flood smart' means understanding the risks you face both in property damage and personal injury where you live or have a business...and taking steps to lessen or mitigate those risk factors. 

About Flooding & Flash Floods

Floods are one of the most common hazards in the United States, however not all floods are alike. Some floods develop slowly, while others such a flash floods, can develop in just a few minutes and without visible signs of rain. Additionally, floods can be local, impacting a neighborhood or community, or very large, affecting entire river basins and multiple states.

Flash floods can occur within a few minutes or hours of excessive rainfall. Overland flooding, the most common type of flooding event typically occurs when waterways such as rivers or streams overflow their banks as a result of rainwater and cause flooding in surrounding areas. It can also occur when rainfall exceeds the capacity of underground pipes, or the capacity of streets and drains designed to carry flood water away from urban areas.
