S.C. Code Ann. § 31-6-20
(A) The General Assembly finds that:
(4) In order to promote and protect the health, safety, morals, and welfare of the public, blighted conditions need to be eradicated and conservation measures instituted and redevelopment of such areas undertaken; to remove and alleviate adverse conditions it is necessary to encourage private investment and restore and enhance the tax base of the taxing districts in such areas by the redevelopment of project areas. The eradication of blighted areas and treatment and improvement of areas by redevelopment projects is declared to be essential to the public interest.
(4.5) There exists in or contiguous to many municipalities in the State large tracts of land which served the people of this State and its economy when originally developed and maintained over the generations as agricultural property, contributing food, fiber, timber, and pulpwood, and which now, in an evolving economy and amidst a much smaller, yet vastly more efficient agricultural economy, are in need of redevelopment to provide multiple uses utilizing the redevelopment tools provided in this chapter.
