Sec. 7a. A municipality may issue bonds or notes from time to time in its discretion to finance the undertaking of any project authorized by this act including, but not limited to, the payment of principal and interest on advances or loans made for surveys and plans for projects authorized by this act. The bonds or notes shall be made payable, as to both principal and interest, solely from the income, proceeds, revenues, and funds of the municipality derived from or held in connection with its undertaking and carrying out of projects under this act. Payment of the bonds or notes both as to principal and interest, may be further secured by a pledge of any loan, grant, or contribution due or to become due from the federal government or other source in aid of projects of the municipality under this act. Bonds or notes issued under this section shall not constitute an indebtedness within the meaning of constitutional, statutory, or charter debt limitations or restrictions, and may be issued without vote of the electors of the municipality. Bonds or notes issued under this section are declared to be issued for an essential public and governmental purpose, and, together with interest thereon and income therefrom, shall be exempted from all taxes. Bonds or notes issued under this section shall be authorized by resolution or ordinance of the legislative body of the municipality. Bonds and notes issued under this section are subject to the revised municipal finance act, 2001 PA 34, MCL 141.2101 to 141.2821.
