   4. (iv) the present condition or use of the proposed project area substantially impairs the sound growth of the municipality, retards the provision of housing accommodations, or constitutes an economic liability or is detrimental to the public health, safety, or welfare, as shown by the existence within the proposed project area of at least four of the following factors:

   5. (v)

      1. (A) at least 50% of the privately-owned parcels within the proposed project area are affected by at least one of the factors, but not necessarily the same factor, listed in Subsection (1)(a)(iv); and
