No person shall remove or convert to his own use or possession any salvage from any beach within the regulated area without first having obtained a permit to do so from the Parks and Recreation Department, and no removal shall be permitted, except in strict accordance with the terms of a permit.

These prohibitions do not apply to the collection of common flotsam for personal use, such as glass floats, length of rope or cable of less than 100 feet, and other minor objects commonly picked up by beach users as an incident to their recreational use of the ocean shore. However, when such objects are attached to salvage, such as fixtures on a vessel hull or objects that were apparently packaged or crated in such a manner that they constitute valuable cargo or property of another, the foregoing prohibitions are applicable.
