The Department of Land Use & Transportation's mission is twofold:

  • Building and maintaining a great transportation system
  • Planning and protecting the uses of the land

Working in coordination with our city, regional and state government partners, approximately 300 LUT employees provide a wide range of transportation, planning, permitting and road maintenance services.

Our land use, planning, development review and building permitting/inspection functions are located in the Public Services Building (PSB), 155 N First Avenue, Suite 350, in downtown Hillsboro. Our road-related functions are located at the Walnut Street Center (WSC), 1400 SW Walnut St. on Hillsboro's west end. Visit our LUT Office Locations and Hours page for more information.
