Title 48 › CHAPTER 4 — PUERTO RICO › SUBCHAPTER I — GENERAL PROVISIONS › § 749
Gives the government of Puerto Rico control of harbor areas, navigable streams, waters, and the underwater land around Puerto Rico and nearby islands that the United States owned on March 2, 1917, except for parts the United States kept for public use. Those areas must be managed the same way as the other lands listed in the nearby rules. U.S. laws that protect and improve navigation still apply there unless they clearly do not fit locally. Any permits or powers the Secretary of the Army or other U.S. officers lawfully used before March 2, 1917 remain in effect. "Submerged lands" — land covered by tides up to the average high-tide line, all land under the navigable waters there, and filled or reclaimed land that used to be underwater. "Navigable bodies of water" — waters from the coast of Puerto Rico and nearby islands out to three marine leagues, including changes from erosion or accretion. "Control" — full ownership and authority, including the rights to manage, lease, use, and develop the underwater land and its natural resources.
