2010 Statewide Federal Aid Urban Boundary & Functional Classification Review


After each decennial census, FHWA requires state DOTs to use census data to review and update all federal Aid Urban Boundaries (FAUB) and the corresponding Functional Classification (FC) of public roads (Title 23, Section 103, USC). This statewide review gives local agencies the opportunity to place more of their roads on the federal aid highway system. The Road Inventory and Classification Services Unit is coordinating Oregon´s statewide review. This page will be updated regularly to provide maps, instructions, and other useful tools for completing this review.
