Gov. Bruce Rauner on Thursday vowed to “do everything possible to help people and communities” affected by the late December and early January flooding.

FEMA will work with its state counterpart as well as the U.S. Small Business Administration and county emergency management agencies beginning next week to document the extent of damage to homes and businesses in Alexander, Christian, Clinton, Douglas, Iroquois, Jersey, Madison, Randolph, Sangamon and St. Clair counties.

Their findings will help the state determine whether to seek federal financial assistance. The review will also document storm-related costs to local governments in 19 Illinois counties, including those slated for property damage assessments.
