Any person who knowingly leaves open, cuts or tears down, or breaks a fence or gate on any property inside the Grass Valley livestock control area and such act results in livestock roaming within the enclosed area of Grass Valley shall be considered the custodian of such livestock. This is for purposes of this Chapter only and then only to the extent of any penalties imposed by this Chapter whether in the form of fines, impounding, caring, feeding, or rounding up such livestock. The fact that a fence or gate was left open, cut or torn down, or broken is prima facie evidence that such was done knowingly. (Ord. 173 §10, 2000)
