Article 1. General of California Government Code >> Division 3. >> Title 4. >> Part 2. >> Chapter 15. >> Article 1.

When a city legislative body determines that it is beneficial to the city and if an equal or greater sum of money has been made available from private sources, it may appropriate and expend money from the general fund for making surveys, maps, plans, and plats and for obtaining information preliminary to the development, improvement, and construction of a deep water canal, waterway, or water facilities for transportation purposes across, in, or along the county where the city is located or any adjoining county.

A city whose limits include or bound upon a harbor, bay, estuary, or other navigable body of water may:
  (a) Establish, acquire, construct, improve, and maintain in, upon, and along the body of water, piers, docks, wharves, bulkheads, quays, and other necessary works.
  (b) Construct, improve, dredge, deepen, or straighten, channels, turning basins, canals, slips, and waterways to, from, and along such works and connecting with any other navigable water within or without the city limits.
  (c) Do any thing necessary or convenient to the establishment, improvement, conduct, and maintenance of a harbor, and in furtherance of commerce and navigation. This section does not affect or limit a person's use and enjoyment of his property rights, nor grant a city the right to destroy, injure, impair, or interfere with any private or quasi-public property or property rights, leasehold, or otherwise, or to the use and enjoyment of such property.
