California Government Code
It is declared to be the policy of the state:
(a) To protect and promote the sound development of economic opportunity in cities and counties and the general welfare of the inhabitants of those communities through the employment of all appropriate means.
(b) That whenever the creation of economic opportunity in cities and counties 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 advance or
expend public funds for these purposes, and to provide a means by which
economic opportunity can be created.
(c) That the creation of economic opportunity and the provisions for appropriate continuing land use and construction policies with respect to property acquired, in whole or in part, for economic opportunity 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 cities and counties.
(d) That the necessity in the public interest for the provisions of this part is declared to be a matter of legislative determination.
