Look to Part II, Chapter 21, Article IV, Public Assembly Ordinance.
Sec. 21-73. Restricted and prohibited public assemblies.
(a) No person shall stage, promote, conduct, engage in, participate in, aid, form, advertise or start any public assembly in or on any public property that is not in or on a public right-of-way or public park, except in an area as may be designated by the county administrator and under conditions which ensure that the manner in which the public assembly is conducted will not be incompatible with the principal purpose and use of the public property.
(b) Notwithstanding anything in this article which may appear to the contrary, no public assembly shall be permitted at any non-traditional public forum, including the county corrections facility.
