For these reasons it is declared to be the policy of the State:
(a) To protect and promote the sound development and redevelopment of blighted areas and the general welfare of the inhabitants of the communities in which they exist by remedying such injurious conditions through the employment of all appropriate means.
(b) That whenever the redevelopment of blighted areas cannot be accomplished by private enterprise alone, without public participation and assistance in the acquisition of land, in planning and in the financing of land assembly, in the work of clearance, and in the making of improvements necessary therefor, it is in the public interest to employ the power of eminent domain, to advance or expend public funds for these purposes, and to provide a means by which blighted areas may be redeveloped or rehabilitated.
(c) That the redevelopment of blighted areas and the provisions for appropriate continuing land use and construction policies in them constitute public uses and purposes for which public money may be advanced or expended and private property acquired, and are governmental functions of state concern in the interest of health, safety, and welfare of the people of the State and of the communities in which the areas exist.
(d) That the necessity in the public interest for the provisions of this part is declared to be a matter of legislative determination.
