The federal government has required local units of government to adopt regulations which restrict activities on land designated by federal special flood hazard maps as being subject to 100 year flooding. These regulations are incorporated into Moultrie County zoning and subdivision regulations. They are fairly restrictive and allow only very limited activity without variation of the regulations. If there is any uncertainty as to whether a property is subject to the flood regulations, the applicant must provide certified information as to the elevation of the building site in relation to the 100 year special flood hazard boundaries. Check with the Department of Planning and Zoning to ascertain any potential problem with designated flood hazard areas.
The Moultrie County Ordinance for Regulating Development in Special Flood Hazard Areas may also be able to help answer some of your questions. You can find that here.
If property is in a floodplain, additional permits may be required. The Illinois Department of Natural Resources and the Army Corps of Engineers may have jurisdiction over your area. Construction in a floodplain may require a Flood Elevation Certificate by a registered professional engineer or architect.
A joint application with the IDNR and Army Corp of Engineers is required to build in the floodplain in Moultrie County.
