It is hereby declared that the provision of new and improved community facilities is necessary to care for the increasing number of persons afflicted with mental disability. Such facilities should be located close to the people they serve in order to speed rehabilitation and restoration and to provide for out-patient care, in-patient care, including aftercare, diagnostic and rehabilitative services, and residential accommodations for operation as hostels. Such facilities should supplement the services provided by the commissioner and the department of mental hygiene and should be available to cities and counties operating approved community services programs pursuant to the provisions of article eleven of this chapter.

It is hereby further declared that non-profit corporations should be created to construct, acquire, reconstruct, rehabilitate, own, and operate such facilities and that provision should be made for mortgage loan participation by a lending institution or the New York state housing finance agency in order to insure that the full resources of the private enterprise sector of the economy may be made available for this purpose; that there is a need for public assistance to such corporations by the granting of tax exemption; that it is the policy of the state to promote the provision of community facilities by such nonprofit corporations; and that such provision is a public use and purpose.
