City Council hearings were the culmination of a three-and-a-half-year effort to update the mapping of Portland’s Environmental Overlay Zones using computerized remote mapping techniques. Over the course of the project, staff held a variety of public outreach events and conducted hundreds of site visits to field verify maps of natural resources.
The Ezone Project made changes to the ezone mapping on thousands of sites around the City of Portland. Project staff will spend the coming months making updates to the Official Zoning Maps to reflect those changes. The adopted changes to the Official Zoning Maps and to the Zoning Code (Chapter 33.430) will go into effect on October 1, 2022.
