Upon approval of the determination as provided in the preceding Section, the Department, as agent for the municipality, may proceed to acquire by gift, purchase or condemnation the fee simple title to all real property lying within the area included in the redevelopment project, including easements and reversionary interests in the streets, alleys and other public places lying within such area. If any such real property is subject to an easement the Department, in its discretion, may acquire the fee simple title to such real property subject to such easement if it determines that such easement will not interfere with the consummation of a redevelopment plan. If any such real property is already devoted to a public use it may nevertheless be acquired, provided that no property belonging to the United States of America, the State of Illinois or any municipality may be acquired without the consent of such governmental unit and that no property devoted to a public use belonging to a corporation subject to the jurisdiction of the Illinois Commerce Commission may be acquired without the approval of the Illinois Commerce Commission. Each Department, as agent for the municipality, is hereby vested with the power to exercise the right of eminent domain. Condemnation proceedings instituted hereunder shall be brought by and in the name of the municipality and shall be in all respects in the manner provided for the exercise of the right of eminent domain under the Eminent Domain Act.
Any determination to acquire a particular slum or blighted area, or any other area which may constitute a redevelopment project, as herein defined, heretofore made by a land clearance commission prior to the effective date of this amendatory Act of the 102nd General Assembly pursuant to the Blighted Areas Redevelopment Act of 1947 (repealed) and heretofore approved by the State Housing Board and the governing body of the municipality, shall be sufficient to authorize acquisition by the Department, as agent for the municipality, of all or any of the real property included in such area.
