A municipality shall have the right to acquire by condemnation, in accordance with the procedure provided for condemnation by such municipality for other purposes, any interest in real property, which it may deem necessary for a community renewal project under this chapter after the adoption by the local governing body of a resolution declaring that the acquisition of the real property described therein is necessary for such purpose. Condemnation for community renewal of blighted areas is declared to be a public use, and property already devoted to any other public use or acquired by the owner or a predecessor in interest by eminent domain may be condemned for the purposes of this chapter.
The award of compensation for real property taken for such a project shall not be increased by reason of any increase in the value of the real property caused by the assembly, clearance, or reconstruction, or proposed assembly, clearance, or reconstruction in the project area. No allowance shall be made for the improvements begun on real property after notice to the owner of such property of the institution of proceedings to condemn such property. Evidence shall be admissible bearing upon the insanitary, unsafe, or substandard condition of the premises, or the unlawful use thereof.
