US Flood Risk Map

A new online flood risk map has been released by the nonprofit organization First Street Foundation.  The online tool can tell you the current flood risk for your home and possible future risks.

The flood model used by Flood Factor is based on models of flood risk from rainfall, overflowing rivers high tides, and coastal storm surge.  It takes into account such as factors as flooding history, elevation and proximity to water.  To predict future risk of flooding other factors are also taken into account, such as different climate models and predicted sea level rise and predicted future precipitation patterns in the local area.  Check it out!
