Transportation System Plan

TSP Cover Page

The Transportation System Plan (TSP) defines the future of the County’s transportation system. It considers projected population, employment growth and community aspirations. The TSP outlines policies and strategies to meet existing and future travel needs for:

  • Vehicles
  • Pedestrians
  • Bicycles
  • Transit
  • Freight 

The TSP provides guidance on how to build, operate and maintain the County’s major roadway network, while addressing elements of the larger transportation system including multiuse trails, state highways and railroads maintained by other agencies.
