The For the purpose of identifying flood zones to determine flood insurance rates, the Flood Insurance Rate Maps prepared by the Federal Emergency Management Agency for Kane County are currently used.
For the purpose of regulating property development, the above mentioned FEMA Flood Insurance Rate Maps are used to determine whether or not a property is subject to special building requirements.
Information on whether your property is in the 100-year floodplain can be obtained by visiting the Public Works Engineering Division at 1405 South 7th Avenue. Maps are available to look at as well as other flood-related information. The City also has Elevation Certificates for new development available dating back to 1992. Contact the Public Works Engineering Division at (630) 377-4486 for further assistance.
Building Improvements and Floodplain Management Standards
Do you know that there are specific requirements for buildings located in the floodplain? The National Flood Insurance Program requires that if the cost of improvements to a building or the cost to repair damages (from any cause) to a building exceeds 50% of the market value of the building (excluding land value), the entire building must be brought up to current floodplain management standards. Building improvement projects include exterior and interior remodeling, rehabilitation, additions, repairs, and reconstruction projects. Additionally, the 50% threshold is a cumulative value. The cost of currently planned improvements will be added to the cost of previously made improvements and compared to the existing market value to determine if the improvements exceed 50% of the structure’s value. Please contact the Public Works Engineering Division at 630-377-4405 for more information.
