N.J. Stat. § 32:2-18
If for the purposes of establishing a steamship terminal or purposes incidental thereto, including temporary construction purposes, in connection with the development or improvement of the Little Basin of the Morris canal in Jersey City, the port authority shall find it necessary or convenient to acquire any real property, in addition to the Little Basin property, whether or not contiguous therewith and whether for immediate or future use, in Jersey City within the area bounded on the north by York street, on the west by Jersey avenue and a southerly extension thereof, on the south by the Tidewater Basin and on the east by the state line, the port authority may find and determine that such property, whether a fee simple absolute or a lesser interest, is required for public use, and upon such determination said property shall be deemed to be required for such public use until otherwise determined by the port authority. With the exceptions hereinafter specifically noted, said determination shall not be affected by the fact that the property has theretofore been taken for, or is then devoted to, a public use, but the public use in the hands of or under the control of the port authority shall be deemed to be superior to the public use in the hands of any other person.
