This ordinance amends the San Francisco Park Code to extend its applicability to parks and open spaces on Treasure Island and Yerba Buena Island that are designated for public recreational use. It also clarifies that the Park Code applies to properties managed by the Recreation and Park Department under various agreements, including Mission Bay Parks, and allows for future application to other properties operated for recreational purposes, subject to Recreation and Park Commission approval. Furthermore, the amendment permits the public use of paved paths on Treasure Island and Yerba Buena Island at any time for traversing purposes. This ensures consistent rules for public safety, park operations, and recreational use across these areas, without altering the jurisdiction or ownership of the Treasure Island Development Authority.
