Portland is not a coastal city but is situated along the Willamette and Columbia Rivers, which are subject to Oregon's Greenway overlay zones. Title 33 (Planning and Zoning) Chapter 33.440 establishes the Greenway Overlay Zones that regulate development along the Willamette River to protect scenic, recreational, and ecological values.
The Willamette Greenway Plan and associated overlay zones restrict development within setback areas along the river. Greenway review is required for most development, exterior alterations, and tree removal within the overlay zone. The regulations aim to protect riparian habitat, public access, and river views. Portland's environmental overlay zones (e-zones) further restrict development near rivers and streams under Chapter 33.430.
Development without required Greenway review approval is a code violation. The Bureau of Development Services enforces overlay requirements. Unauthorized clearing or construction in the Greenway overlay may require restoration of the site to pre-development conditions.
