Under the Burton Act and Charter Section B3.581, the San Francisco Port Commission has the complete and exclusive authority to manage, regulate and control the harbor of San Francisco and to do all things it deems necessary in connection with the use, conduct, operation, management, maintenance, regulation, improvement and control of Port property. The Port has important interests in regulating activities on public access areas of Port property to protect visitors from safety hazards, prevent damage to the property and facilitate special event coordination. As a result, the Port has determined that there is a need to impose reasonable time, place and manner restrictions upon activities of the general public on the Port's public access areas. In keeping with its duties of administering the public trust, this Code is not intended to restrict the rights of the public to enjoy the waters of San Francisco Bay to the full extent those rights are granted under the public trust doctrine.
