Urban Area Adjustments:

Federal law requires that Highway Urban (and Urbanized) Area (HUA) boundaries be reviewed and adjusted as necessary after each US decennial census. The Washington Adjusted Urban Area (AUA) process took place in the first half of 2013. A Boundary Review Team was assembled to oversee the process. The Federal Highway Administration (FHWA) approved the resulting HUA boundaries in summer 2013. Details of the AUA process can be viewed at http://www.wsdot.wa.gov/planning/2010UABoundaries.htm

 

HUA Functional Classification Changes:

FHWA requires a functional classification review following adjustments to HUAs. All agencies affected by HUA changes must review their roads and streets within areas that have changed from rural to urban or urban to rural. Affected counties began their review of county roads on August 13th. On October 16th cities and MPO’s affected by the HUA changes were sent a request to review their roads and assess them for any changes necessary to their existing arterial or collector functional classifications. Arterial or collector classification changes resulting from the review need to be sent to WSDOT (Mitch Vernon 360-570-2441). These changes should be listed, preferably in an Excel spreadsheet, and provided along with a map, showing the name of the roadway, beginning and ending termini, functional classification, urban or rural status, and the reason for the functional class change. All changes need to be submitted to WSDOT by December 5th.

 

Normal WSDOT Functional Class Supplement process is temporarily suspended:

Note that any FC change requests received as part of the normal functional class change supplement process will not be reviewed until the HUA FC review detailed above is completed. FC change requests after the HUA FC review process will follow the normal FC change supplement status.
