Full Breakdown
Within Washington County, Beaverton's Development Code Chapter 60.60 designates Significant Individual Trees, Historic Trees, Mitigation Trees, and trees within Significant Natural Resource Areas or Significant Groves as Protected Trees. It is unlawful to remove or prune a Protected Tree's canopy or disturb its root zone except as the code allows. During development, a four-foot orange construction fence must ring each protected tree's root zone, where new buildings, grading, trenching, and vehicle staging are barred. Actual heritage designations are mapped in the city's Comprehensive Plan Volume III, not the Development Code itself.
