Whenever the mayor declares that a state of civil disorder exists, the mayor may promulgate any, all or part of the temporary restrictions provided for in section 5-3-3 of this chapter, with such limitations and conditions as the mayor may deem appropriate under the circumstances. In so doing, the mayor shall specify the area of the city affected by each restriction. Any measure promulgated will take effect only after reasonable notice of its contents has been given. (2000 Code § 38.02)
