Section 1
SECTION 1. Where it is made manifest to the Secretary of Commerce and Police that the establishment of harbor lines is essential to the preservation and protection of harbors, bays, and navigable lakes or rivers, he is hereby authorized to cause such lines to be established, beyond which no piers, wharves, bulkheads, or other works shall be extended or deposits made, except under such regulations as may be prescribed from time to time by him: Provided, That wherever the Secretary of Commerce and Police grants to any person or persons permission to extend piers, wharves, bulkheads, or other works, or to make deposits in any harbor, bay, or navigable lake or river of the Philippine Islands, beyond any harbor lines established by authority of the Insular Government, he shall cause to be ascertained the amount of tide water to be displaced by any such structure or any such deposits, and he shall, if he deem it necessary, require the parties to whom the permission is given to make compensation for such displacement either by excavating in some part of the harbor, including the tide water channels between high and low water marks, to such an extent as to create a basin for as much tide water as may be displaced by such structure or by such deposits, or in any other mode that may be satisfactory to him.
