This rule establishes the procedure and criteria by which highways shall be functionally classified as required by Utah Code Ann. Section 72-4-102.5
The Department incorporates by reference Federal Highway Administration Publication No. FHWA-ED-90-006, "Highway Functional Classification - Concepts, Criteria, and Procedures" (U.S. Department of Transportation, March 1989). The publication will be referred to as the "Functional Classification Manual".
A request to consider changing the functional classification of an existing roadway may be initiated by an official of the local transportation agency responsible for the route, by the Metropolitan Planning Organization with jurisdiction over the proposed change, or by a Department staff member. Requests are to be forwarded to the Department's Systems Planning and Programming Division through the office of the local Region Director.
(1) The procedure the Department uses to determine the functional classification for roads will follow the concepts and procedures identified in the Functional Classification Manual and will meet the guidelines relating to the extent of road miles and vehicle miles traveled of rural and urban functional classification systems. The final system will be as reviewed and approved by the Federal Highway Administration.
(2) Traffic volumes and road mileage will come from data the Department reports on an annual basis. Population information will be taken from the most recent U.S. Census information.
(1) The schedule to update the Functionally Classified Road System is based on the U. S. Census, with a major 10-year update initiated after the release of census date. There will also be a mid-census review and an opportunity for annual adjustments.
(2) The major, or decennial update, begins after the US Census Bureau releases information on urban and urbanized areas based on population and population density. This is historically completed about three years after the census count. Boundaries for small urban and urbanized areas are initially determined by the Census Bureau. They are then adjusted to fit local conditions by the Department in consultation with the underlying local authorities responsible for transportation. Road functional classifications are then determined by the Department, using the same consultation process and the concepts, procedures, and criteria identified in the Functional Classification Manual. The recommended functional classification changes are then forwarded to the local Federal Highway Administration Division Office for review, approval, and adoption as the Functionally Classified Highway System for the state.
(3) The mid-census review is initiated by the Department approximately five years after the major update has been completed and is similar to the decennial update. Road functional classifications are reviewed on the entire system, using the procedures and criteria identified in the Functional Classification Manual. The Department will consult with local officials and forward recommended changes to the local Federal Highway Administration Division Office for review, approval, and adoption. Changes to urban boundaries and related rural or urban classifications are not considered in this review.
(4) Each year, the Department will review proposals to make changes in functional classification. This adjustment considers routes that experienced changes that were unforeseen during the regular system-wide review process and which are of a time-sensitive nature that precludes waiting for the next regular review. This adjustment is for minor revisions only and will not consider changes in mileage or vehicle miles traveled limits, boundary, or urban-rural classification changes.
