Oregon City strives to accommodate growth in a responsible and sustainable manner. With regard to land use and transportation, this involves a need to balance property owners’ rights to develop their land and the City’s goal to plan for and provide a transportation system that serves its intended function in a safe, reliable, and predictable manner for the public.  See the link below for the document that describes the City’s required content for a Transportation Analysis Letter (TAL) and for a Transportation Impact Study (TIS). In general terms, the TAL is applicable to smaller developments that are presumed to have a lesser transportation impact. The TIS applies to larger developments that are presumed to have a greater transportation impact.
