The purpose of this division is to provide flexibility in the review and approval of land uses and structures which are needed and intended to serve legitimate public or private purposes on a temporary and non-permanent basis. Temporary uses and structures are those uses and structures that may or may not be permitted in a given zone district, but which may be allowed on a non-permanent and temporary basis upon individual review of their proposed nature, location, duration, impact, and compatibility with surrounding permitted uses and structures within the underlying zone district; excepting outdoor merchandising or retail uses or displays, which shall not be permitted as temporary uses. Notwithstanding the foregoing, this division shall not be applicable to temporary uses or structures associated with major or minor festival events, which shall be reviewed and permitted in accordance with Chapter 11, Article 4 of the Municipal Code.
