Descriptive name | Flood Hazard Zones - FEMA Digital FIRM - 1999 | |
File name | fk_dfirm | |
Spatial domain | Pima County | |
Abstract | FK_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. This layer is based on the 1999 release of the Digital FIRM data by FEMA. Updates to this data have been applied up to June 16th, 2011. | |
