An area shall be determined to be a blighted or deteriorated area if:
(a) A preponderance of the structures therein is detrimental to the public health, safety or welfare by reason of age, dilapidation, overcrowding, faulty arrangement, lack of ventilation or sanitary facilities, or any combination of these factors, and which is detrimental to the public health, safety or welfare because a preponderance of structures within the area fails to conform in one or more respects to the provisions of these Codified Ordinances relating to building, housing and sanitation; or
(b) There is a preponderance of defective or inadequate street layout, or faulty lot layout in relation to size, adequacy, accessibility or usefulness, or unsanitary or unsafe conditions, or deterioration of site improvements, or conditions which endanger life or property by fire or other causes. However, at least twenty-five percent (25%) of the structures in the area must be structurally deficient in the same manner and to the same extent as set forth in subsection (a) hereof.
