The Functional Class - State Trunk Network feature service is an export of the functional classification layer in the SDR (DOT1_GISBIZ.STN_FUNCTIONAL_CLASS) and is intended for use in the IDA application only to aid the damage assessment team. This data was exported on 04/27/26. For current functional classifications contact the DTIM systems planning unit or refer to the DOT1_GISBIZ.STN_FUNCTIONAL_CLASS layer in the SDR.
Note: The default layer symbology settings use a reclassified grouping for functional class descriptions. These are as follows:
Field: FFCL_CD (original values = description)
Values 9-15 = Rural Principal Arterial
Values 49-62 = Urban Principal Arterial
Values 20-25 = Rural Minor Arterial
Values 70-83 = Urban Minor Arterial
Values 30-34 = Rural Major Collector
Values 40-41 = Rural Minor Collector
Values 90-95 = Urban Collector
Value 45 = Rural Local
Value 97 = Urban Local
Pop-up attributes for the layer are titled with the more granular functional class type description within the grouped value.
