Do You Need a Permit to Clear Land in Oregon?

Oregon has no single statewide land clearing permit. What you need depends on three things. What the ground is, what you do with the debris, and whether you dig.

Plenty of brush and blackberry work on dry upland ground outside city limits runs with no clearing permit at all. The rules that do come up are about notice, water, smoke and digging. Here is how they sort out in the mid-Willamette Valley.

What decides whether you need a permit?

Start with four questions about the ground. Is it forestland under Oregon law? Is there a wetland, creek or wet spot on it? Is it inside city limits, or in a mapped floodplain?

Then ask two more about the work. Are you burning the debris or grinding it up? Are you moving dirt or pulling stumps?

Each answer points at a different agency. A building lot cleared before the build starts can touch several at once. A back pasture often touches none of them.

Do you need a permit to clear forestland in Oregon?

Oregon law defines forestland as land used for growing and harvesting forest tree species. How the land is zoned or taxed does not change that.

If your ground fits, the Forest Practices Act applies. The statute says an operator, timber owner or landowner must notify the State Forester before starting an operation. The Oregon Department of Forestry asks for that notice at least 15 days before the work begins. The person responsible for the work files it, in ODF’s online system, FERNS.

Clearing forestland for a house site is on ODF’s own activity list. So is changing land use to a non-forest use. The same filing covers a permit to use fire or power driven machinery.

Not sure your ground counts as forestland? Call your local ODF office. A stewardship forester makes that call.

What if there is a wetland or a creek on the property?

Oregon’s removal-fill law is run by the Department of State Lands. A permit is required for most projects that move more than 50 cubic yards of material in wetlands or waters.

Some ground is tighter than that. Any amount of material needs a permit in streams mapped as Essential Salmonid Habitat. The same goes for State Scenic Waterways and designated mitigation sites. DSL also lists grading and dredging in wetlands as work that usually needs a permit.

DSL will not permit a project without local approval, so the county or city comes first. On our jobs, scope near a creek or a soft wet corner gets planned with you first.

Do city tree rules apply inside city limits?

City ordinances are their own layer. In Albany, a permit is required to remove a street tree. A permit also covers any tree inside city limits with a circumference of five and one quarter feet. That is roughly 20 inches across.

Albany’s development code adds a site plan review for bigger jobs. It applies when you cut five trees or more that are each eight inches across or larger.

Other valley cities write their own versions, so ask the city before a saw starts. Rural lots outside city limits usually fall under county planning instead.

Which county permits come up on rural land?

Floodplain rules catch more clearing work than people expect. Benton County counts filling, excavating or grading your property as development. Those projects all require a floodplain development permit.

The county also tells owners to remind whoever does the work to get floodplain approval first. Counties differ, so check yours before dirt moves in a mapped floodplain.

Some cities and counties also require a grading or fill permit once the volume passes a set threshold. We can point you at who to ask for your address. That comes up most when clearing runs into excavation and grading work on the same parcel.

For rural lots around Lebanon, Linn County Planning and Building is the first call.

Do you need a permit to burn the brush piles?

Burning is where local rules bite hardest. DEQ says cities, counties and local fire districts set their own open burning restrictions. A local ordinance may require a permit beyond the state minimum. DEQ tells you to check with your fire department before burning.

Land clearing debris is not treated like yard debris either. DEQ’s open burning rules put material from clearing a site for land improvement or cleanup in the same category as torn-down buildings. Slash burning on forest land needs a permit from the Oregon Department of Forestry.

Closer to home, the Lebanon Fire District issues agricultural and slash burn permits. The permit holder confirms the burn dates with the district first. That district also holds open burning to daylight, from 7:30 a.m. to two hours before sunset.

Lane County adds another agency. LRAPA runs outdoor burning there, with two seasons a year, one in spring and one in fall. Local fire districts can narrow those seasons further.

Forestry mulching skips this whole section. The mulcher head grinds brush and small trees into chips on the ground. Nothing is left waiting on a burn day.

Can fire season stop the work?

It can, on forest ground. Once fire season is declared, ODF and its partners restrict public and work related activities in protected areas.

For work, ODF posts Industrial Fire Precaution Levels. A forestry mulcher on a skid steer is ground based mechanized equipment, so those levels reach it. At the higher levels that equipment typically runs only between 8 p.m. and 1 p.m. At IFPL IV, all operations are prohibited.

We watch the level for your district and plan around it. In summer that can move a start date.

How far ahead do you call 811 before digging?

Oregon 811 is the easy one, and it is free. Contact 811 before you dig, then wait two business days before the bucket goes in.

Weekends and holidays stretch that window. A request made after 5 p.m. counts as the next business day. The marks are good for 30 days. Keep power equipment 24 inches clear of them.

Stump dig-outs move earth, so a clearing job with stumps gets a locate too.

Who do you call for what?

What does Willamette Valley Land Clearing do about permits?

This page is not legal advice. Rules change, and they vary by county, city and fire district. The agency has the final word on your property.

What we do is plan the work around what applies. We look at the ground and get the utility locate called in. We watch the fire season level, and we say when a city or county call is worth making.
