(1) The state, acting by the Commissioner of Housing, may enter into a contract with a municipality, acting by its redevelopment agency, for state financial assistance for a redevelopment or urban renewal project under this chapter, in any redevelopment area or urban renewal area in such municipality, as defined in this chapter; provided such project shall have been approved by the United States Department of Housing and Urban Development for an advance for surveys and plans, a loan or grant contract or a neighborhood development program under Title I of the federal Housing Act of 1949, as amended, and provided a contract between the municipality and the federal government for a federal capital grant-in-aid shall not have been entered into prior to May 9, 1958. Such contract may provide for financial assistance by the state in the form of a grant equal to one-half of the excess of the net cost of the project as determined by the commissioner over the federal grant-in-aid thereof; provided, in determining such net cost for purposes of providing state financial assistance from any funds becoming available after July 1, 1963, by legislative enactment, the commissioner shall neither recognize nor credit as municipal noncash contributions any expenditures by the state of Connecticut, other than state grants for urban renewal or redevelopment or schools, which relate in any way to any urban renewal or redevelopment project, and provided, with respect to state financial assistance from any funds becoming available after July 1, 1963, by legislative enactment, in any instances in which noncash contributions provided by any private, nongovernmental source exceed one-half of such excess of the net cost of the project as determined by the commissioner, the state grant or advance-in-aid for urban renewal or redevelopment shall be reduced by an equal amount. In determining the net cost of a project, nothing shall prevent the commissioner from including costs in excess of the original projected costs of such project, provided such excess cost has been approved by the United States Department of Housing and Urban Development. Contracts for state financial assistance for urban renewal or redevelopment projects executed under the provisions of this chapter prior to July 1, 1967, or contracts executed subsequent thereto for which reservations of state funds were approved by the Connecticut Development Commission prior to July 1, 1967, may be amended or executed under the provisions of this chapter and administrative procedures established hereunder, provided, if such amendment is for the purpose of providing additional state financial assistance due to an increase in the net cost of the project, as determined by the commissioner, such additional state financial assistance shall be made available from funds previously authorized for redevelopment or urban renewal programs or authorized for the purposes of this chapter and chapter 133.

(2) Any municipality which acquires or retains title to all or part of the land contained in any urban renewal or redevelopment area as defined in § 8-125 or 8-141, for not less than the use value of such property in accordance with § 8-137, may sell, lease, dedicate, donate or otherwise dispose of such land for less than said use value, provided there is constructed thereon housing solely for persons or families of low or moderate income, as defined in § 8-202; provided nothing herein shall be construed to limit the power of any municipality to retain any redevelopment project land for any use for which such municipality is authorized for other purposes.
