Descriptive name		Flood Hazard Zones - FEMA Digital FIRM
File name		fp_dfirm
Spatial domain		Pima County
Abstract		FP_DFIRM shows areas in Pima County prone to 100-year and shallow 100-year flood events. ZONES A, AE, AH, AO # and AO - ALLUVIAL FAN # comprise the extent of the 100-year floodplain. The tailing numbers in the ZONE AO strings indicate flood depth in feet. ZONE D shows areas that have not been mapped by FEMA (primarily federal and tribal lands). Zone X shows areas that have been mapped but are outside of the 500-year floodplain. ZONE X -SHALLOW 100-YEAR shows the extent of the shallow 100-year floodplain, the 500 year floodplain and Areas protected by levee. The layer FP_ZONEX provides subclassifications for these areas. Note, FP_LOMX can be used to augment FP_DFIRM for large-scale mapping. Also note, FP_DFIRM should be used in conjunction with FP_SS for the floodprone land brochure mailings sent out by PCRFCD on an annual basis. For general FIRM information: See more information.
