The Council of the City of Los Angeles hereby finds that the Marina del Rey Entrance Channel is a unique portion of the City of Los Angeles and requires special rules and regulations which cannot properly be applicable to any other portion of the City of Los Angeles. The reason for said uniqueness is that the Marina del Rey Entrance Channel is owned by the County of Los Angeles but is located within the City of Los Angeles. It is the means whereby small boats traverse from the Pacific Ocean into the Marina del Rey, a small boat harbor owned and operated by the County of Los Angeles and located within unincorporated territory. The provisions of this article shall be applicable only to the Marina del Rey Entrance Channel.
