"Blighted area" defined.
Unless the context clearly indicates otherwise, for the purpose of this chapter, "blighted area" means an area (other than a slum area as defined in § 11-7-2) where by reason of the predominance of defective or inadequate street layout, faulty lot layout in relation to size, adequacy, accessibility, or usefulness, or other insanitary or unsafe conditions, deterioration of site improvements, diversity of ownership, tax delinquency, defective or unusual conditions of title, improper subdivision or obsolete platting, or any combination of such reasons, development of such blighted area (which may include some incidental buildings or improvements) into predominantly housing uses is being prevented.
