Change of date! Marshall Park Neighborhood Association meeting moved to May 9

The Portland Bureau of Planning and Sustainability is in the process of correcting ezone maps around the city. Staff are attending neighborhood meetings throughout Portland to explain the project and answer questions from the community. 

In early April, postcards were sent to property owners throughout SW Portland, sharing information about opportunities to learn more about the Ezone Update Project.

The meeting with the Marshall Park Neighborhood Association (formerly on April 11) has been rescheduled.

Project staff will be at the Marshall Park Neighborhood Association meeting on May 9 at 6 p.m. at Capitol Hill Elementary School.

Next week staff will be at:

  • April 15 at 6:00 p.m. – Tryon Creek Watershed Council
  • April 16, 7:30 p.m. – Hillside Neighborhood Association
  • April 17, 7 p.m. – SWHRL Board Meeting
  • April 18 at 7 p.m. – SWNI Watershed Committee

Who will be affected by this project?

If you own property in Southwest Portland and ...

  1. You have existing ezones on your property;
  2. The ezones are proposed to change on your property; or
  3. New ezones are proposed for your property.

... you may be affected by changes to the ezone and you should have received a postcard in early April.  We expect the environmental overlay zones will only change slightly on most properties. But some properties may have expanded ezones; others may have smaller ones.

Find your property on a map

You can use the Ezone Review Mapto look up your property. This map will tell you what kinds of environmental protections apply now and what are proposed to change. You can also request a site visit through the Ezone Review Map, and staff will come to your property to review the data.

How do I use the Ezone Review Map?

What are environmental overlay zones

What’s an ezone? It’s a tool that the City of Portland uses to help protect important natural resources, such as streams, wetlands, forests, steep slopes, wildlife habitat and floodplains for more than 30 years. Since the ezones were applied in the NW Hills between 1992 and 1999, new development has occurred, trees have grown or died, and creeks and streams have shifted their course.

Also, technology has improved so much that we can more accurately map the important resources that should be protected. This project is using this new technology and on-the-ground site visits to realign the ezone boundaries to match the actual location of natural resource features on the ground.
