Base Flood Elevations (FEMA)

FEMA DFIRM (Digital Flood Insurance Rate Map) base flood elevations effective December 18, 2012, created for Boulder County and all municipalities within under the direction of the FEMA Map Modernization project. This data supercedes all other flood data. Per FEMA: Data included on this CD-ROM represents Final Flood Insurance Rate Map (FIRM) data that has been published as effective FIRM or DFIRM information. The data are the official and legal representation of the effective flood zones. Boulder County added a field, "Regulating Entity" to distinguish this from Boulder County regulatory floodplain.
