Subdivision Floodplain Program
The State of Michigan has thousands of miles of rivers, streams, creeks, and lakes that add beauty and value to home sites. Aside from aesthetic value, their natural purpose is to convey or store storm water runoff. This can pose dangerous conditions as large rain events can turn babbling brooks into raging rivers. Each year losses reach into the millions of dollars from homes and businesses destroyed or damaged by flooding.
