US: Conservation district in Illinoisis aiding flood plain mapping update. The state is updating its floodplain maps, and the Macon County is part of the process. The conservation district board in its meeting, discussed work being done by the Illinois State Water Survey.

“Flood insurance risk rates have the potential to decrease as the water survey updates and digitizes its maps for the first time in some areas since the 1980s. The difference between water levels found on the maps compared to the actual floodplain has been up to 3 feet in some cases. It’ll outline in more specific way where you shouldn’t develop areas. The more accurate maps would reduce risk and prevent people from developing on flood-prone areas. Sludge is being removed from two sewage lagoons on district property so it can be restored, which will alter its floodplains. We try to determine where floodplains are at all the time,” said Paul Marien, operations manager for the district.
