In order to adequately remove snow and to avoid property damage as far as possible, it is necessary to keep public streets and highways clear of all parked vehicles and other obstacles left on or adjacent to the travelway during snowstorms. Therefore, when snow removal becomes necessary, no person who owns or has possession, custody or control of any vehicle or other object shall park or place such vehicle or object upon or immediately adjacent to any street travelway until the street is cleared. This prohibition does not apply to physicians or other authorized emergency service personnel. Any such vehicle or object so parked or placed is declared a public nuisance. (1985 Code § 12-4-4)
