General Notice to Control Noxious Weeds

The Utah Noxious Weed Act, Utah Code Annotated, 4-17-1 et-al, Sec. 7, specifically states, that it is the responsibility of any person who owns or controls land in the State of Utah, to control any noxious weeds growing on such land and to prevent the spread of same by cutting, tillage, cropping, pasturing or treating with chemicals or other effective methods or combination thereof, approved by the County Weed Control Supervisor, and as often as may be required to prevent the weed from blooming and maturing seeds or spreading by root, root stalks or other means.

When the land owner or person in possession of property within Sanpete County, upon which noxious weeds are present, fails to control or prevent their growth and spread, the County Weed Control Supervisor, or any member of the County Weed Board, has the prerogative to notify the property owner that their property can, and may be declared a Public Nuisance. Five days after your property has been declared a Public Nuisance, the County may, after reasonable notification, enter the property without your consent, and perform any work necessary, consistent with sound weed prevention and control practices, to control the weeds.

Any expense incurred by the County in effecting the control of said noxious weeds shall be charged to you, and any expenses which remain unpaid 90 days after being assessed shall become a lien on the property and shall be collectable by the County Treasurer at the time of collection of the general taxes.
