Floodplain Information

If you are in the floodplain, more detailed information is available, such as determining base flood elevations and past flooding problems. Flood insurance references are available at FEMA as well as City Hall.


The Flood Insurance Rate Map (FIRM) above provides only general information of flood probabilities to residents. A specific flood hazard determination can only be made by the authorized floodplain administrator since additional information is considered that is not available on the FIRM.
