Placeholder projects – A “placeholder” project is used as a surrogate for a project that has not yet been
defined. Placeholder projects are generally used in study areas, and serve primarily as mechanisms for esti-
mating the impacts on the rest of the transportation system of a project that will be identified later as part of
study area analysis.

Principal Arterial – Principal Arterials (Freeways and Highways) form the backbone of the motor vehicle
network. These routes connect over the longest distance (often miles) and are spaced less frequently than
other Arterials or Collectors. These highways generally span several jurisdictions and often have statewide
importance. At a minimum, highways that are classified by ODOT as Interstate or Statewide Highways are
considered Principal Arterials.

Project Review Committee – Project Review Committee (PRC) acts in a technical advisory capacity for the
review of all public transportation improvement applications for completeness and conformance with the
applicable requirements of Article VII of the Community Development Code, the applicable Community Plan
or Rural/Natural Resources Plan, and the Transportation Plan. The PRC consists of representatives of all af-
fected Department of Land Use & Transportation divisions, and may include representatives of other county
departments and affected agencies as appropriate. The PRC provides recommendations to the Review
Authority.

ADOPTED TEXT tion, interchange or other element of the roadway system.
Queue – A line of stopped vehicles in a roadway travel lane, typically delayed by congestion at an intersec-

Regional Transportation Functional Plan (RTFP) – The Regional Transportation Functional Plan codifies the
requirements that local plans must comply with to be consistent with the Regional Transportation Plan.

Regional Transportation Plan (RTP) – The official intermodal transportation plan that is developed through a
regional transportation planning process and adopted by Metro.

Refinement Area – Locations that have been identified where further study is needed to determine the
mode, function and/or general location of a future solution or transportation improvement. Further study of
a refinement area may occur through a transportation planning process, capital project development or the
land development process. Before development may occur on land within a refinement area, the develop-
ment application must demonstrate how potential solutions to the transportation need will (at a minimum)
not be precluded by the proposed development.

Right-of-Way (ROW) – Land or an easement over land dedicated for public road purposes. Including the right
to construct, operate and maintain a public road, all customary associated uses and appurtenant facilities.

Road Design and Construction Standards – Standards set forth in the Washington County Code. The Road
Design and Construction Standards set out engineering standards for road improvements, and provide guid-
ance for the design and construction of public roads and associated improvements to the county’s transpor-
tation system.

Road Fund – The State Highway funds generated by the State gasoline tax and other revenues, allocated to
unincorporated Washington County, plus the local Washington County gasoline tax. These funds are used for
road maintenance.
