(a) The legislature has found in the Housing Authorities Law (Chapter 392) that:
(1) unsafe and unsanitary housing conditions exist in this state for persons of low income;
(2) there is a shortage of safe and sanitary dwellings for those persons;
(3) those conditions require excessive and disproportionate expenditures of public funds for crime prevention and punishment, public health and safety, fire and accident protection, and other public services and facilities; and
(4) the public interest requires the remedying of those conditions.
(b) The legislature finds and declares that:
(1) the assistance provided under this chapter to remedy the conditions described in the Housing Authorities Law constitutes a public purpose and an essential governmental function for which public money may be spent and other aid given;
(2) it is a proper public purpose for a public body to aid a housing authority that operates within the boundaries or jurisdiction of the public body or to aid a housing project within its boundaries or jurisdiction because the public body derives immediate benefits and advantages from the authority or project; and
(3) this chapter is necessary in the public interest.
