Review of ezones in Southwest Portland underway

Residents in SW are invited to talk with City planners about the Environmental Overlay Zone Map Correction Project at drop-in hours in April.

The Portland Bureau of Planning and Sustainability is in the process of correcting ezone maps around the city. Ezones are a tool to help protect natural resources, such as trees, streams, steep slopes and wildlife habitat in Portland.

The Environmental Overlay Zone Map Correction Project team is now reviewing the ezones in SW Portland. Property owners and other interested community members are invited to talk with City Planners about changes to the ezones maps during drop-in hours at Capitol Hill Library, 10723 SW Capitol Highway:

  • April 24, 11 a.m. – 1 p.m.
  • April 30, 4-6 p.m.

Staff will have online maps for you to look at and can talk about how the project may affect your property.

What is the Ezone Map Correction Project?
The Environmental Overlay Zone Map Correction Project will correct the boundaries of the conservation (c), protection (p), and Pleasant Valley (v) zones to match the locations of streams, wetlands, floodplains, forests, steep slopes and wildlife habitat. Project staff started work in areas near Johnson Creek, then expanded to the northeast neighborhoods. This spring the project is focused on the Northwest and Southwest Hills. Work on ezones in the Columbia Slough and Columbia River will begin this summer. 

How will this affect you?
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 Map to 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.

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

Ezone Update Project presentation scheduled for April 11 has been cancelled. City planners will be presenting at the May 9 neighborhood association meeting instead.

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.

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.

Ezone Update Project

Residents and property owners in Northwest Portland are invited to review draft remapped environmental overlay zones and attend neighborhood meetings in February, March and April.

Environmental planners head to the hills ... Northwest Hills, that is.

The Portland Bureau of Planning and Sustainability is in the process of correcting ezone maps around the city. Ezones are a tool to help protect natural resources, such as trees, streams, steep slopes and wildlife habitat in Portland.

So far, staff have produced draft maps and conducted site visits in Johnson Creek Watershed as well as the Eastern Buttes and Terraces in N/NE Portland to update the ezones there. 

Now, we’re headed to the Northwest Hills for site visits and conversations with property owners.

Portland’s Buttes and Terraces in NE Portland Reviewed for Environmental Protections

Residents living near Rocky Butte, Sullivan’s Gulch, Pier Park, Mocks Crest, Waud Bluff or other northeastern buttes and terraces are invited to review draft remapped environmental overlay zones and attend neighborhood meetings in December and January.

The City of Portland has been protecting streams, wetlands, forests, steep slopes, wildlife habitat and floodplains for more than 30 years. But since 1989, streams have shifted their course, new development has occurred, and technology has improved so much that we can more accurately identify the important resources that need protecting.

So, we’re “rematching” the environmental overlay zones, or ezones, to the actual location of natural resource features on the ground.

What’s an ezone? It’s a tool that the City of Portland uses to protect important natural resources, like streams, wetlands and forests.

How will this affect you?

We expect the overlay zones will only change slightly on most properties. But some properties will receive expanded ezones; others may have reduced ezones. 

You can use the Ezone Review Map to look up your property and determine what kinds of environmental protections apply. You can also request a site visit through the Ezone Review Map and staff will come to your property to review the data.

Johnson Creek and Outer Southeast Portland: Updated Environmental Overlay Zone Map ready for review

Second draft map of corrected ezones for the Johnson Creek watershed and outer Southeast Portland are ready for community/neighborhood review.

Ezones are a tool that City planners use to protect Portland’s important natural resources — like streams, floodplains, wetlands, forests and steep slopes. These natural resources are woven throughout all of Portland in neighborhoods, commercial districts and industrial areas. The resources are home to fish and wildlife, are places where people go to recreate and relax, and provide important functions like reducing air temperature, improving air quality, managing stormwater and flooding and reducing risks of landslides.

Getting it right

Last summer, staff shared the first draft of corrected ezones for the Johnson Creek Watershed and the outer east areas of Portland south of I-84. Planners discussed the updates with residents at six neighborhood meetings, conducted more than three dozen site visits and held two drop-in hours.

Based on their analysis and public input, staff refined the location of ezones for the Johnson Creek area and its tributaries, as well as southeast buttes, including Mt Tabor and Kelly Butte.

The second draft of the ezone maps are available on the Ezone Review Map.

Many property owners that received a site visit should be able to see changes to the draft ezones on their properties.

Postcards in the mail

The second draft also includes some new properties. After revising the mapping protocols to better reflect previously adopted plans, 45 new properties were included in the ezones.

If your property is proposed for remapping, a postcard is in the mail. Please use the Ezone Review Map to see the corrected ezone boundaries.

How do I use the map?

Request a site visit

If you currently have an ezone on your property or you think you are getting one through this project, you can request a free site visit from BPS staff. Staff use site visits to verify data on the location of natural resources and correct errors in our draft ezone maps.

If you would like to request a site visit, or if you have any questions or concerns about the ezone mapping on your site, please:

Staff can provide more detailed ezone and natural resource maps for individual sites by request.
