(a) Weeds and dry grasses over four inches in height, dead shrubs, dead trees or tree limbs within ten feet of a structure or chimney, or any vegetation growing upon the streets, sidewalks, or upon private property within the city, which bear seeds of a wingy or downy nature or which by reason of their size, manner of growth and location constitute a fire hazard to any building, improvements, crops and other property, and weeds and grasses, which, when dry, will in reasonable probability constitute such a fire hazard, are declared to be public nuisance.
(b) Cultivated and useful grasses and pastures shall not be declared a public nuisance. However, if the fire chief or his or her authorized representative determines that a firebreak is necessary to protect adjacent improved property from fire exposures, an adequate firebreak shall be required as determined by the fire chief or his or her representative.
