A Housing Authority may, whenever it determines that an area within the municipality or county may be eligible for designation as a conservation area within the meaning of subsection (1) of Section 17 of this Act, make such investigation and hold such hearings as may be required, including at least one public hearing held within the area, which shall be noticed and give opportunity for the residents of the area affected to be heard as provided in Section 8.3a of this Act. Any hearing may be conducted by the Authority or by a Committee appointed by it, consisting of one or more members of the Authority. The Authority may after such hearing designate such areas as conservation areas for the purposes of this Act. The designation, together with an accurate description of the area included in such designation, shall be made by resolution of a majority of the Commissioners of the Authority, and be a part of the records of the Authority.
Following such designation the Authority shall draw up or have submitted for its approval a conservation plan for the area, which plan may include but is not limited to (1) land uses, residential and non-residential; (2) improvement, alteration, or vacation of major and minor streets, alleys and highways, provision for restricted service access, and off-street parking; (3) locations and easements for public utilities; (4) community facilities; (5) open space necessary or desirable for the effectuation of a conservation project; (6) landscaping and site engineering; (7) building restrictions; (8) recommended construction including new buildings, rehabilitations and conversions, demolition of designated structures, and elimination of non-conforming uses; (9) population density, ground coverage, and number of dwelling units recommended; (10) recommended standards of maintenance, and requirements of applicable health and safety ordinances; (11) zoning or rezoning required; (12) costs and financing arrangements of public portions of the plan; (13) recommended timetable of various stages of the program; (14) any and all other steps needed to carry out the plan. Such plan shall conform to the comprehensive plan, if any, of the municipality or county.
Upon completion the plan shall be submitted to the governing body of the municipality or county, together with a request for such implementing legislation as may be required and within the authority of the governing body of the municipality or county and the opinion of the plan commission of the municipality or county, if any, on the merits of the plan.
The governing body of the municipality or county shall by resolution adopt or reject the plan. Following favorable action by the governing body, the Authority shall certify the plan as adopted and transmit a certified copy of the plan and of the resolution adopting it for written approval or rejection by the Department. No plan shall be of any force or effect until it has been approved in writing by the Department. Following favorable action by the Department, the Authority may thereafter exercise in such areas the powers granted under this Amendatory Act of 1963.
