The Federal Emergency Management Agency (FEMA) has completed a multi-year project to update the Flood Insurance Rate Map (FIRM) panels for Maricopa County and on October 16, 2013 the new FIRM panels will become official. Mortgage lenders, determination companies, and insurance companies will be required to use the updated FIRMs to determine the flood risk of a structure and if flood insurance is required.
Information on how to contact various communities in Maricopa County for floodplain and flood insurance rate map questions for a specific parcel or property may be found on the Information Sources page. Information can also be found at http://www.floodsmart.gov/floodsmart/
