The City of Portland has been protecting rivers, streams, wetlands, forests, wildlife habitat, flood areas and steep slopes for more than 30 years. But advances in technology since 1989 have created a mismatch between the mapped environmental overlay zones and the actual location of natural resource features on the ground. The Bureau of Planning and Sustainability is going to fix that!
What's an ezone?
How will this affect you?
This project may adjust environmental overlay zones on as many as 15,000 properties in Portland. We expect the overlay zones on many of these properties will only change slightly. Some properties will have an expanded e-zone; others may have a reduced overlay zone.
You can view a map of the overlay zones, find your property and determine what kinds of environmental protections apply.
How do I use the map app?
The Ezone Map Correction Project is starting in the Johnson Creek Watershed area and Outer East (south of I-84) this summer (2018). Staff are available for site visits to individual properties.

Project staff will also be attending neighborhood meetings in August and September to talk with residents and answer questions. Look for a meeting near you on the project calendar.
Assessment of the Columbia Slough and Columbia River will start in winter 2018-19, followed by the Northwest Hills in summer 2019 and Southwest Hills in spring 2020.
