The weed management of county maintained rights-of-way is the responsibility of the Larimer County and mandated by the Colorado Noxious Weed Act. Property owners requesting no spray are responsible for noxious weed management within that zone. Failure to comply will result in Larimer County resuming spraying operations. The posting requirements listed below must be met if the County is to honor a request to refrain from treating an area with herbicides.
To request County Road No Spray areas, please go to https://onlineportal.larimer.org, or call us at (970) 498-5768 for more information.
