Planning Branch is responsible for the processing updates of
Federal Functional Classification System
North Carolina. The 2005/ 2006 update was initiated
due to the Decennial Census revision of Urban Area
Boundaries. In May 2002, the
US Bureau of the Census designated revised/new
Urbanized Areas (UZAs) and Urban Clusters (UCs)
based on the 2000 Census. While the USDOT has
no direct role in the designation of these areas,
they are used in the administration of the
surface transportation program. Key FHWA / FTA program
impacts for planning and environmental are:
designation of MPOs and application of metropolitan
planning requirements; designation of Transportation
Management Areas (TMA); application of Air Quality
Conformity requirements; and, allocation of funding.
For more information about Functional Classification
North Carolina's 17 Urbanized Areas (population >50,000) the
changes were mutually established between the MPO
and NCDOT. Of the 90 Urban Clusters within the
State (population between 2,500-50,000), 56 were
greater than 5,000 population and were processed
under the urban functional classification
guidelines. The remaining Urban Clusters
and other rural areas were processed using the Rural
functional classification guidelines.
NCDOT's GIS Unit is responsible for maintaining the
maps and scanned images.
