The General Assembly finds that:
(1) there are in the area of operation of the Washington Authority unsafe and unsanitary housing and a shortage of safe and sanitary housing for persons of eligible income;
(2) these conditions cause too much public money to be spent for crime prevention and punishment, public health and safety, fire and accident protection, and other public services and facilities;
(3) the public interest requires the remedying of these conditions;
(4) the assistance provided under this title to remedy these conditions is a public use and purpose and an essential governmental function for which public money may be spent; and
(5) this title is necessary in the public interest.
