Notwithstanding the provisions of § 10.99, establishing the penalty for violation of the Municipal Code as a misdemeanor, the prosecutor, in his or her sound discretion, may prosecute a violation of this chapter as an infraction, rather than as a misdemeanor. The prosecutor may also reduce or agree to the reduction of a previously filed misdemeanor to an infraction. Every person, firm, partnership, association, or corporation convicted of an infraction for violation of any provision of this chapter shall be punished by a fine not exceeding $100 for a first violation, a fine not exceeding $200 for a second violation of the same section within a year and a fine not exceeding $500 for each additional violation of the same section within one year. A fourth violation within one year shall constitute a misdemeanor. Each day such violation continues may be regarded as a new and separate offense.
