Sec. 4. The works board may condemn, rent, or purchase any real or personal property needed by the city for any public use, unless a different provision for purchase is made by statute or ordinance. However, the city legislative body may by ordinance:
(1) require that these condemnations, rentals, or purchases be included in a long-range capital expenditure program to be proposed by the works board and updated as required by the legislative body, but at least annually;
(2) require the works board to estimate, at least annually, expenditures needed for condemnations, rentals, and purchases for each successive fiscal year;
(3) approve, amend, or reject all or part of the long-range capital expenditure program and the proposed annual expenditures, before or during the adoption of the city budget; and
(4) specify the manner in which the works board must itemize the estimates of capital program expenditures for each fiscal year.
