|Descriptive name||Flood Hazard Zones - FEMA Digital FIRM|
|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.
