Name: FEMA 2008 Flood Hazard Areas

Display Field: FLD_ZONE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: OBJECTID: System-generated unique identifier for each record within the feature classFLD_AR_ID: Unique identifier for the flood areaFLD_ZONE: Flood Zone. This is a flood zone designation. These zones are used by FEMA to designate the Special Flood Hazard Areas (SFHAs) and for insurance rating purposes.FLOODWAY: Floodway Type. Floodway areas are designated by FEMA and adopted by communities to provide an area that will remain free of development to moderate increases in flood heights due to encroachment on the floodplain. Normal floodway areas are ‘floodway’. Special cases will have a note on the hardcopy FIRM. If the corresponding area is not designated as a floodway, this field is null.SFHA_TF: Special Flood Hazard Area. If the area is within SFHA this field would be True. This field will be true for any area that is coded for any A or V zone flood areas. It should be false for any X or D zone flood areas. Enter “T” for true or “F” for false.STATIC_BFE: Static Base Flood Elevation. For areas of constant Base Flood Elevation (BFE), the BFE value is shown beneath the zone label rather than on a BFE line. In this situation the same BFE applies to the entire polygon. This is normally occurs in lakes or coastal zones. This field is only populated where a static BFE is shown on the FIRM.V_DATUM: Vertical Datum. The vertical datum indicates the reference surface from which the flood elevations are measured. Normally this would be North American Vertical Datum of 1988 for new studies. This field is only populated if the STATIC_BFE field is populated.DEPTH: Depth Value for Zone AO Areas. This is shown beneath the zone label on the FIRM. This field is only populated if a depth is shown on the FIRM.LEN_UNIT: Length Units. This unit indicates the measurement system used for the BFEs and/or depths. Normally this would be feet. This field is only populated if the STATIC_BFE or DEPTH field is populated.VELOCITY: Velocity Measurement. This is shown beneath the zone label on the FIRM for alluvial fan areas (certain Zone AO areas). This value represents the velocity of the flood flow in this area. This field is only populated when a velocity is shown on the FIRM.VEL_UNIT: Unit of Measurement for the Velocity Attribute. This is shown in the legend where alluvial fans are present. This field is only populated if the VELOCITY field is populated.AR_REVERT: If the area is Zone AR, this field would hold the zone that the area would revert to if the AR zone were removed. This field is only populated if the corresponding area is Zone AR.BFE_REVERT: If Zone is Zone AR, this field would hold the static base flood elevation for the reverted zone. This field is populated when Zone equals AR and the reverted zone has a static BFE.DEP_REVERT: If Zone is Zone AR, this field would hold that flood depth for the reverted zone. This field is populated when Zone equals AR and the reverted zone has a depth assigned.SOURCE_CIT: Source Citation. Abbreviation used in the metadata file when describing the source information for the S_Fld_Haz_Ar table. Normally, the flood hazard area polygon will be divided to distinguish areas modified by the most recent revision from areas based on the effective FIRM prior to the most recent revision. Revisions and sources prior to the most recent revision will not be tracked for individual polygons in the flood hazard areas table in the standard database.SOURCETYPE: Accuracy context for the recordFEATUREID: GIS-Consortium-generated unique identifier for each record within the feature class. All FEATUREIDs start with the GEODBID of the community that owns the record.REPLICAFILTER: Code used to filter data for the creation of custom geodatabasesDATECREATED: Date/time stamp from the moment the GIS record was createdSOURCE: Organization that provided the data. The GIS Consortium standard is to preface the source with the three-letter municipal code of the community providing the data, followed by a dash. Example: VGV-Public WorksGEODBID: Three-digit code that assigns editing responsibility to a community in the GIS ConsortiumPRODUCTIONNOTES: Technical notes from GIS personnelDATEMODIFIED: Date/time stamp from the last moment the GIS record was changedGlobalID: System-generated unique identifier for each record that is required in replicated geodatabasesSHAPE: System-generated geometry type of the featureSHAPE.area: System-generated area of the featureSHAPE.len: System-generated length of the feature
