Summary
Layton defines a 'weed' for code-enforcement purposes to include any plant specified as a noxious weed under the Utah Noxious Weed Act, Title 4, Chapter 17 of the Utah Code, under LMC 6.24.020(11)(e). Any such species, plus vegetation that is a fire hazard or vermin harborage, must be kept under one foot tall or eradicated.
"Weeds" shall mean: a. vegetation that has become a fire hazard; b. vegetation that is noxious, a nuisance, or dangerous; c. grasses, stubble, brush, tumbleweeds, clippings, and cuttings that endanger the public health and safety by creating a fire hazard; insect, rodent, or other vermin harborage, or other nuisance; d. poison ivy; and e. plants specified as weeds in the Utah Noxious Weed Act, Title 4, Chapter 17, Utah Code (as amended), and its subsequent regulations.
Full Breakdown
020(11) defines 'weeds' for Layton's Weeds and Refuse chapter to include, at (e), 'plants specified as weeds in the Utah Noxious Weed Act, Title 4, Chapter 17, Utah Code (as amended), and its subsequent regulations,' incorporating the state's noxious/invasive species list directly into the local definition rather than maintaining a separate city list. The same definition also independently covers vegetation that is a fire hazard, that is noxious, a nuisance, or dangerous, grasses, stubble, brush, tumbleweeds, clippings, and cuttings that create a fire, insect, or rodent-harborage hazard, and poison ivy specifically.
070 sets the operative standard: any regulated weed, including a species specified under the state Noxious Weed Act, must be maintained at no more than one foot in height at all times, eradicated by chemicals, cutting, or another approved method, and the cuttings promptly cleared from the property; root-removed or rototilled weeds must be buried, hauled off, or composted as the law allows. The Director can grant a firebreak exception of at least fifteen feet around structures on parcels of roughly ten acres or more, and can exempt low-risk land such as 'hollows' or forest-service property with Fire Chief and Davis County Health Department concurrence. 080.
Violations & Fines
Allowing a noxious weed species covered by the Utah Noxious Weed Act, or any weed generally, to exceed one foot in height is a violation of LMC 6.24.060 and 6.24.070; a violation carries the penalty set in Utah Code 76-8-301 under LMC 6.24.080, and the director may pursue enforcement jointly with Davis County Weed Control or the State Department of Agriculture.
