No Spray Program

Every spring Benton County Public Works Department begins its Annual Roadside Shoulder Spraying Program to control weeds along county roads. Roads are sprayed 2-4 feet from the edge of the road in order to control encroachment of plant growth on the asphalt surface. Spraying of noxious weeds and roadside vegetation, including blackberries, is done throughout the year, and extends to the far side of any ditching. For homeowners who do not want chemical sprays adjacent to their property and who are willing to assume responsibility for controlling weeds along the roadway, a No Spray Agreement may be entered into with the County.

No Spray Agreement: As a property owner/resident, you may elect to enter into an annual agreement with Benton County whereby the County will not spray herbicides along the roadway, nor along the ditch line in front of your property. In exchange, you agree to be responsible for vegetation control on your property frontage. Please read the No Spray letter, complete the Vegetation Control Permit and Vegetation Control Liability Release form, then return them to Benton County by March 4th via mail or email. Permits must be renewed annually.

Return the completed permit and liability release form via email or mail to the following address:

Benton County Public Works 360 SW Avery Ave Corvallis, OR 97333-1192

No Spray Signage: No Spray signs must be posted by March 18th. See the sign placement diagram example.

You may notify us by phone at 541-766-6012 or email if you no longer want to participate.

If you are interested in a modified spray program, (for example: spraying for noxious weeds but not roadside grasses), please call our office at 541-766-6012.
