The payment of relocation costs and replacement housing costs to persons dislocated by highway construction is hereby declared to be a cost of highway construction and may be paid from the state road fund, subject to the provisions of this section. The commissioner of highways shall make the payments authorized by this section to reduce hardships to persons so dislocated. In addition, the commissioner shall render advisory assistance to persons affected and shall call upon and coordinate the services of such other agencies of state and local government as may be capable of rendering such assistance to reduce hardships to persons affected and to reduce delays in highway construction. In rendering such advisory assistance, the commissioner may accumulate and maintain lists of various kinds of properties available to which persons affected may be relocated, and acquire and file such other information and take such other action as may be necessary to render such advisory assistance. With respect to persons dislocated by federal-aid highway projects, the commissioner shall provide a relocation assistance program which will comply with and implement the federal laws and regulations relating to relocation assistance to displaced persons as set forth in the Uniform Relocation Assistance and Real Property Acquisition Policy Act of 1970, being Public Law 91-646 enacted by the Ninety-first Congress of the United States of America, and the 1987 amendments thereto known as Title IV of the Surface Transportation and Uniform Relocation Assistance Act of 1987, being Public Law 100-17 enacted by the One Hundredth Congress of the United States of America.

Any individual, family, business concern (including the operation of a farm) or nonprofit organization to be displaced by a highway construction project shall be compensated consistent with the provisions and limitations of federal acts for reasonable and necessary costs to be incurred in consequence of being so displaced. When a family is displaced, no additional payment shall be made to individuals who are members of such family; but, if two or more displaced families occupy the same dwelling or comprise a single household, each family within such dwelling or household may receive relocation costs as provided in this section. Payments under this section are subject to the limitations provided herein and to any rules and regulations made by the commissioner as herein provided.

With respect to state highway projects and federal-aid highway projects, the commissioner shall have authority to make such payments for relocation costs, reestablishment costs, replacement housing costs, including the increased interest costs which the displaced person is required to pay for financing the acquisition of a comparable replacement dwelling, and reasonable expenses incurred by such displaced person for evidence of title, recording fees, and other closing costs incident to the purchase of the replacement dwelling, and expenses incidental to the transfer of property as are authorized by the abovementioned Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970, being Public Law 91-646 enacted by the Ninety-first Congress of the United States of America, and the 1987 amendments thereto known as Title IV of the Surface Transportation and Uniform Relocation Assistance Act of 1987, being Public Law 100-17 enacted by the One Hundredth Congress of the United States of America.

Such rules and regulations may authorize lump sum payments to individuals or families, in lieu of their respective provable costs, based upon the size of the dwelling being vacated or the number of persons being affected or any other reasonable basis. The commissioner may authorize the obligations of or payment of relocation costs in advance of expenditure for relocation by any person, firm or organization eligible to receive such payment where such advance obligation or payment would speed the clearance of highway construction sites or reduce hardships.

With respect to state highway projects and federal-aid highway projects, the commissioner shall also have authority to comply with the aforesaid federal laws and regulations relating to providing last-resort replacement housing.
