What Causes Flooding?

Increased development and a changing climate across the Garden State are a double whammy that causes more flood damage to homes and businesses, unless our state and local governments take bold action.

The physics is pretty simple: a warmer atmosphere creates more evaporation and more precipitation during storms.

As hard surfaces like asphalt and concrete roads, driveways and parking lots increase, there is less room for water to percolate into the ground, causing more runoff and flooded roads and houses.
