In response to an immediate and credible threat to national security, the mayor may close or otherwise restrict access to public places as allowed in this chapter. For purposes of this chapter, the term "public place" is defined under section 24.30.010 of this Code.
(AO No. 2002-102(S), § 2, 8-6-2002)
Where not otherwise specifically authorized under this Code and to protect national security, the mayor may also close or otherwise restrict access to a public place if the procedures set forth in A—C of this section are followed.
A. 
The mayor may close or restrict access to any public place in the interests of national security for no more than 30 days with such process and under such terms and conditions as he or she alone determines appropriate.
B. 
Should the mayor determine that national security requires the closure or restrictions on access to a public place for more than 30 but not more than 90 days from the date of initial action, he or she shall within 30 days of his or her initial action meet with the assembly and explain his or her decision.
C. 
Should the mayor wish to maintain closure of a public place or restrictions on access to a public place for any period beyond 90 days in the interests of national security, the procedures of this subsection shall be followed.
1. 
Public notice of at least 15 days before the ninetieth day after the initial action shall be given. Notice shall be given to the relevant community council and be posted on and adjacent to the public place involved and published. The notice shall also advise the public of the time and place set for a public meeting and the availability of relevant public documents which were consulted in making the proposed action.
2. 
Upon at least 15 days' notice before the ninetieth day after the initial action, a public meeting shall be conducted in the nearest suitable public facilities in the affected areas. The meeting shall be attended by the person or persons primarily responsible for making the decision to extend the road closure or restricted access beyond ninety days. The public shall be given a reasonable opportunity to comment on the action during the meeting.
3. 
With the notice of the public meeting, the public shall be given free and unrestricted access to all records and documents upon which the decision is based, unless that access is otherwise prohibited by federal, state, or municipal law.
4. 
When issuing a final decision closing or restricting access to a public place in the interests of national security beyond 90 days under this subsection, the mayor shall issue written findings that support and explain the proposed action. The findings shall be based on substantial evidence in the public record that an immediate and credible threat to national security requires the action beyond the 90-day period described above and shall reflect meaningful consideration of less restrictive or alternate measures.
(AO No. 2002-102(S), § 2, 8-6-2002; AO No. 2009-134, § 1, 1-12-2010)
Within a reasonable time after August 6, 2002, the mayor shall promptly remove any restriction on the use of, or access to any public place imposed no more than 90 days prior to unless August 6, 2002 unless that action was lawfully taken by the mayor under other provisions of this Code or the Home Rule Charter.
