Attribute Information

_FIRM_ID_Primary key for table lookup. Assigned by table creator.
_ST_FIPS_State FIPS. This is the two-digit code that corresponds to the State Federal Information Processing Standard (FIPS) code. This is a standard numbering system used by the Federal government, defined in FIPS Pub 6-4. These two numbers correspond to the first two digits of the panel number. Acceptable values for this field are listed in the D_State_FIPS table.
_PCOMM_Community or County Identification Number. This is the third through the sixth digits of the panel number. For community-based maps this corresponds to the FEMA Community Identification number. For countywide maps this is the county (or county equivalent) FIPS code with a “C.”
_PANEL_Panel Number. This is seventh through the 10th digits in the complete panel number. This is assigned by the scale of the map and the position within the community or county. The panel number scheme is described in detail in the FIRM Panel Technical Reference.
_SUFFIX_Map Suffix. This is the final digit in the complete panel number. This is a letter suffix at the end of the panel number. The map suffix is incremented one letter every time the panel gets republished.
_FIRM_PAN_FIRM Panel Number. This is the complete 11-digit FIRM panel number, which is made up of ST_FIPS, PCOMM, PANEL and SUFFIX. This is the FIRM panel number that is shown in the title block of the map.
_PANEL_TYP_Panel Type. The type of FIRM panel identifies whether the panel is printed or not and whether it is community based or countywide. Acceptable values for this field are listed in the D_Panel_Typ table.
_EFF_DATE_Effective Date. This is the effective date of the current map revision. This field is not populated until the FIRM effective date is established and the Final FIRM is ready for hardcopy production by FEMA. Then it is required.
_SCALE_Map Scale. This is the denominator of the FIRM scale as a ratio. For example, 24000 is the denominator for a 1″ = 2000′ map. Acceptable values for this field are listed in the D_Scale table.
_PNP_REASON_Panel Not Printed Reason. This is the explanation for the FIRM panels that are not printed. Only completed if the hardcopy panel is not printed by FEMA. For example, “No Special Flood Hazard Areas.” See the FIS Report Technical Reference for commonly used values.
_SOURCE_CIT_Source Citation. Abbreviation used in the metadata file when describing the source information for the feature. The abbreviation must match a value in L_Source_Cit.
_x_scale_Scale of map, in feet
