Transportation System Plan

TSP Users' GuideThe Washington County Transportation System Plan (TSP) is a component of the Washington County Comprehensive Plan that defines the transportation system desired for the future and how it can be achieved. It identifies transportation systems, as well as outlines policies and strategies necessary to meet existing and future travel needs (motor vehicle, pedestrian, bicycle, transit and freight) based on projected population and employment growth and community aspirations. The TSP was developed in coordination with local city and regional agency partners after a 3-year public involvement process, including the work of a Community Advisory Committee, Interagency Coordinating Committee and many community open houses and public events.

The current TSP was most recently updated by three ordinances adopted by the Washington County Board of Commissioners: A-Engrossed Ordinance 768 (2013), A-Engrossed Ordinance 783 (2014), and A-Engrossed Ordinance 799 (2015). The effective date of the current TSP is November 27, 2015.

TSP Users' Guide

The TSP Users' Guide is designed to provide a "user-friendly" version of the Washington County Transportation System Plan (TSP) for County staff, agency and community partners, and all members of the public. The Users' Guide does not constitute the legally adopted Washington County Transportation System Plan, but instead draws from the appropriate ordinances adopted by the Board of Commissioners. The TSP Users' Guide is based upon the adopted ordinances noted above.

The TSP Users' Guide will be an evolving resource guide. As future updates are adopted, this guide will reflect the adopted changes by the dates they become effective including an updated cover page and document page footers.

*Users should refer to the adopted ordinances if in need of clarification about any information contained with the TSP Users' Guide.
