To the end that the owners of property in the Port of New York District abutting upon streets, avenues or other highways, the established grade of which will be changed by reason of the construction by the Port of New York Authority (hereinafter called the authority) of any public improvement in the Port of New York District, may not suffer undue loss and injury by reason of such change of grade, the authority is hereby authorized and empowered, in its discretion, to enter into voluntary agreements with such abutting owners of property which is built upon or otherwise improved in conformity with the grade of any street, avenue or other highway established by lawful authority in the Port of New York District, whereby it will undertake to pay a fair and reasonable sum to such abutting owners for the damage occasioned by such change of grade to the buildings and improvements on such property. The term "owners" as used in this section shall include all persons having any estate, interest, or easement in such property, or any lien, charge or encumbrance thereon. Such payments which the authority is hereby authorized and empowered to make, shall be in such amounts and shall be payable at such times and under such terms and conditions as shall be agreed upon by and between the authority and such owners concerned.
