R.I. Gen. Laws § 46-25-67
Nothing herein contained shall restrict or limit the powers of the commission arising under any laws of this state, or any ordinances of any municipality, except if the powers are expressly contrary to the provisions of this chapter. This chapter shall be construed to provide a complete additional alternative method for doing the things authorized hereby, and shall be regarded as supplemental and in addition to the powers conferred by other laws. The issuance of all revenue bonds, revenue notes, and other obligations of the commission, under the provisions of §§ 46-25-58 - 46-25-66, need not comply with the requirements of any other statute applicable to the issue of the bonds, notes, and other obligations. No proceedings or notice of approval shall be required for the issuance of any revenue bonds, revenue notes, or other obligations, or any instrument of security therefor except as herein provided.
