Hamilton, IL – Hamilton is a step closer to identifying the flood risk faced by some of its residents. The city's current flood plain map has been in place for neary 25 years. About 5 years ago, the city started working to upgrade that document. The Federal Emergency Management Agency has unveiled its new preliminary flood insurance rate map. The primary focus is on the areas where Railroad and Chaney creeks branch into the city. FEMA spokesperson Eric Kuklewski says this map will show residents the flood risk facing their properties. The old map showed little detail and encompassed many properties within the flood plain. That meant more residents needed flood insurance. The new map provides greater detail and is expected to cut the number of homes requiring the insurance significantly. Kuklewski says the maps could become official in about one year, if no protests are filed.
