Even a foot or so of water around your house from minor flooding can cause severe damage.
There are two ways to protect doorways, the most likely place for water to find a way into your home: Sandbags and Urethane foam.

Sandbags have long been the most common method to get some protection, but many local governments limit the number of sandbags provided to each home, possibly enough to barricade only two doorways. Some have stopped making them available at all.
