River Issues

Frequently Asked Questions

How close can I build to the river in my backyard?

There is a 50' required Riparian Setback (measured from the top of the bank) on the Coast Fork of the Willamette River, Silk Creek, Bennett Creek, and the Row River. If you live along one of these rivers, you should take a look at Section 3.7.300 (Riparian Development) in the Development Code. Construction of buildings, fences, sheds, etc., in this 50' setback are prohibited. Vegetation or tree removal is also prohibited, although invasive species removal is encouraged. For more information on property vegetation management in riparian areas, contact the Coast Fork Willamette Watershed Council.

I live on the Coast Fork of the Willamette River. Are there any special restrictions there?

Yes, the Coast Fork and the lands next to it are designated as the "Willamette River Greenway," and are protected from extensive development by state law. Local standards for Greenway development are found in Section 3.7.400 of the Development Code.

You may also be within the Special Flood Hazard Area or Regulatory Floodway. Please review the Floodplain map or contact our office to check whether your property is within the designated Floodplain. Local standards for Floodplain development are found in Section 3.7.200 of the Development Code.
