Texas is no stranger to flood. With its diverse geography and extensive, hurricane-prone coastline, the state frequently leads the nation not only in structural damage but also in loss of lives related to flooding events. Moreover, Texas is home to "Flash Flood Alley," an area that extends from Del Rio to San Antonio to Austin to Dallas and is prone to rapidly occurring flood events due to its unique topography and the periodic occurrence of significant, heavy rainfall.
Given the deadly nature of floods and the rapid timeframe in which they can occur, being ready for the next flood event is essential. This website provides resources for residents of Texas and visitors alike that will help them prepare prior to a flood, make sound decisions while an event is taking place, and recover once the waters have receded.
We list the most critical steps to take in each stage of the flood preparedness and response process immediately below. Please keep in mind that this list includes only the most essential steps to take; we strongly recommend that you read and consider all of the information on the before a flood, during a flood, and after a flood pages. Additionally, the information contained on this web page is intended as one resource to assist the public. There are other valuable sources of information relating to flooding which should also be considered.

What is a flood?
When thinking about a flood, many individuals envision a hurricane or a wall of water racing down a river. While those types of events often produce floods, nothing quite so dramatic has to occur for flooding to take place. A flood can simply be an overflow of water that submerges land that is usually dry.
Flood can also be defined at a more technical level. According to the National Flood Insurance Program, a flood is defined as:
A general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties […] from one of the following:
- Overflow of inland or tidal waters
- Unusual and rapid accumulation or runoff of surface waters from any source
- Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels that result in a flood as defined above
A flood event may look very different depending on where you are, whether that's in a low-lying coastal area or alongside a steep riverbank, but in all cases, you need to know how to handle the situation.
