The following definitions shall apply in the interpretation and enforcement of this chapter:
(a) "Declaration of snow emergency" means a declaration of a snow emergency event by the EOC in time for public announcement not later than 6:00 p.m. the day of, or, in the case of a probable overnight or early morning start, the day preceding, the event.
(b) "Emergency Operations Coordinator (EOC)" means the City Manager or another City employee so designated by the City Manager, i.e. the Emergency Management Director or a designated department head.
(c) "Primary routes" means designated major arterials and main interconnectors between wards and other municipalities which are used for principal, emergency, commercial, school or bus access. "Primary routes" also includes major, high-volume residential streets. (See the list of designated primary snow emergency routes set forth in Section 486.09.)
(d) "Snow emergency event" means a snow event where accumulation of snow is expected to exceed six inches or where the effects of other types of winter weather create an emergency situation.
(e) "Snow tires" means any tires mounted on drive wheels of vehicles, which tires are designed to give effective traction on snow, mud or ice covered streets by means of extra heavy duty treads with special high-traction patterns, except that no tire so defined shall be construed to be a snow tire if it is damaged or worn to the extent that its performance would be substantially impaired. The performance of a snow tire shall be considered substantially impaired if, when measured in tread groove at two points of the circumference where the tread is thinnest, but not closer than fifteen inches, the tread design depth of such tire measures not less than one-fourth of an inch at both locations.
