(a) The Legislature hereby finds that the greatly increased use by the public of motor vehicles of all kinds has caused serious traffic congestion on the streets of many municipalities in this state; that the lack of adequate planning and supervision of the location of parking facilities, the parking of motor vehicles of all kinds and the lack of adequate parking facilities for motor vehicles of all kinds substantially impede the free circulation of traffic in, through and from many municipalities in this state, impede the rapid and effective fighting of fires and disposition of police officers therein, contribute to the location and relocation of commercial and business enterprises outside of urban areas and retard the development of commerce and business within many municipalities in this state, thereby giving rise to urban blight and adversely affecting or threatening to adversely affect the tax base of such municipalities; that such parking crisis can be reduced by such municipalities providing adequate motor vehicle parking facilities strategically located there; that providing properly located terminal space for motor vehicles is a public responsibility; that fostering the development of commerce and business within municipalities, with the increased tax revenues resulting therefrom, is a public purpose; that fostering the availability of property for charitable use is a public purpose; that the closer the proximity between municipally owned motor vehicle parking facilities and commercial and business establishments the greater the development of commerce and business and the greater the level of revenue produced by such motor vehicle parking facilities; that the erection or construction of pedestrian viaducts, ramps, bridges, tunnels or other pedestrian facilities leading to and from motor vehicle parking facilities so as to facilitate the movement of pedestrians to and from such motor vehicle parking facilities fosters the development of commerce and business and increases the level of revenue produced by such motor vehicle parking facilities; that the leasing, particularly on a long-term basis, and the selling of space for commercial or business use in connection with a municipally owned motor vehicle parking facility will aid the development of commerce and business, increase the level of revenue produced by such motor vehicle parking facility and maintain and increase the tax base of such municipalities; that in many instances the authority for the leasing of space as provided for in this section would assist in financing the construction, reconstruction, establishment, acquisition, improvement, renovation, extension, enlargement, increase, equipment or repair (including replacements) of any such motor vehicle parking facility; that the enactment of this section is for the general welfare of the public and is a public necessity; and that the means and measures authorized in this section are, as a matter of public policy, for the public purposes of such municipalities. This section is enacted in view of these findings and shall be liberally construed in the light thereof.
