(A) Whenever an authority created pursuant to this chapter or Chapter 11 determines that real property acquired in accordance with this chapter, Chapter 10, or Chapter 11 of this title is surplus to its needs, it may so declare by resolution of its commissioners and proceed to sell the real property at public sale; provided that the sale has the prior approval of the council of the city for which the authority was created and that the approval by the council is given only after a public hearing on the proposed sale. (B) As used in subsection (A), an authority's real estate shall not be considered "surplus to its needs" where the authority's commissioners have determined that, although the real estate is no longer needed for its original purpose, the real estate: (1) is suitable for use by the authority for its other purposes or programs, including any home ownership program which provides for the sale of dwellings to persons of low income; provided that the home ownership program has received the prior approval of the council of the city for which the authority was created; (2) is desired for use by another state or local public body for its own public projects or programs, and the authority's commissioners have determined that the real estate should be conveyed to the other public body; provided that the sale or exchange, with or without consideration, has received the prior approval of the council of the city for which the authority was created; or (3) is permitted to be sold or exchanged by the laws of this State in the implementation of any slum clearance or redevelopment project; provided that the sale or exchange has received the prior approval of the council of the city for which the authority was created.
