General Provisions of California Harbors And Navigation Code >> Division 8. >> Part 4.

"District," as used in this part, refers to any port district formed pursuant to this part.
"Board," as used in this part, means the board of port commissioners described in Chapter 2 (commencing with Section 6240).
This part does not repeal, modify or otherwise affect the provisions of any other law relating to port or harbor districts, and no other law providing for the creation of port or harbor districts repeals, modifies or otherwise affects this part or any of its provisions.
Any property owned by any city which is used or held for the purpose of aiding or developing navigation, commerce or fishing may be transferred to the district to be used for the same purposes, and any lands of the State which may have been transferred to any such city may be transferred to the district subject to the trusts and other provisions for the transfer of the lands from the State to the city. A city which is governed by a freeholders charter may only transfer or turn over property if authorized by the provisions of its charter or an amendment thereof.
If any land under a navigable stream is by virtue of any work or improvement by the United States or the State, freed from the easement of navigation and fishing, it reverts to the district, to be used for the purposes for which the district was organized. But if any land is not used or held for such purposes, it reverts to the State.
If the district is dissolved, lands which were granted to it by a municipal corporation revert to that municipal corporation.
