SAN ANTONIO - The San Antonio River Authority has an interactive map you can use to see if your house or business is in or near a floodplain.

It’s important to note these are areas of San Antonio that are prone to flooding, it doesn’t guarantee flooding will happen.

View the map here.

*Due to high traffic on the San Antonio River Authority website, the map may take several minutes to load. Zoom in to see your area and the blue areas indicate a floodplain. The floodplains are all over San Antonio, if you don't see them just give the page an extra minute or two. 

Flood warnings have been issued for many parts of San Antonio and the surrounding areas.

You can view all the weather alerts and warnings issued for your area on here.
