Public Notice: Boundary County Noxious Weed Control

For 2022, the Boundary County Noxious Weed Department will continue to offer weed identification, site review, herbicide type or rate advice, rental sprayers, booklets, brochures and other land management information.

Spraying of Road Rights-of-Way: All county roads will be sprayed with herbicides on weed infested rights-of-way this season, late April through October.

If you do NOT want the right-of-way adjacent to your property sprayed, obtain a NO SPRAY Agreement from the Weed Department. These forms and accompanying “NO SPRAY” signs are free; the sign MUST BE POSTED by the owner at the property corners. Property owners are responsible for the eradication of noxious weeds in those areas. We cannot honor signs that are not obtained from our department and, particularly, without a signed agreement. If weed control has not happened on or before July 1, the marked “NO Spray” area may be sprayed for weed infestations.

Public Notice addition: All property owners who have potable water or irrigation water usage within 50 feet of a county road right-of-way must mark the area of intake as potable water and notify Boundary County Weed Department prior to May 1 of every year.
