Portland’s buttes and terraces in NE Portland reviewed for environmental protections

Posted on

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.

Map of natural resource area under consideration for environmental overlay zone

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.

How do I use the Ezone Review Map?

Postcards in the mail

If you own a property near Rocky Butte, Sullivan’s Gulch, Pier Park, Mocks Crest, Waud Bluff or other buttes and terraces in Northeast Portland and you have existing ezones on your property or the ezones are proposed to change, you will receive a postcard in the mail.
