(a) Procedure. Upon receiving notice that a jury or other trier of fact in a court of law has found that a person issued a permit under this division violated any section of this article, whether or not an adjudication of guilt has been entered, the city manager shall suspend the permit and shall notify the permittee of his action. Notification shall be by certified mail and shall be sent to the address on the permit application, which shall be considered the correct address.

(b) Periods of suspension. A single violation of this article shall result in the suspension of the adult entertainment permit for 30 days. Upon a second violation within a period of two years from the date of a prior violation, but not including any time during which the permit was suspended, the permit shall be suspended for 90 days. Upon a third violation within a period of two years from the first of three violations, but not including any time during which the permit was suspended, the permit shall be suspended for 180 days. All periods of suspension shall begin on the 15th day from the date the city manager mails a notice of suspension to the permittee or on the date the permittee delivers his permit to the city manager, whichever comes first.

(c) Surrender of permit required. If a permittee, after having been mailed notice of the suspension of his permit in the manner provided in this section, fails to surrender his permit to the city manager within 15 days, the period of suspension of the permit shall be extended until and shall not expire until a period has elapsed after the date of surrender of the permit or after the date of expiration of the permit, whichever comes first, which is identical in length with the original period of suspension.
