The Director shall cause the Department to study the conditions existing in the several cities and counties, to confer with the judges of the juvenile and domestic relations district courts, the directors and boards of social services, and other appropriate officials, as the case may be, and to plan, establish and operate unless otherwise provided an adequate and coordinated program of probation, parole and related services to all juvenile and domestic relations district courts in counties or cities heretofore served by regional juvenile and domestic relations courts, and where specialized probation, parole and related court services were not provided as of July 1, 1973, and to counties and cities that request a development of a court service unit with the approval of the governing bodies after consultation with the chief juvenile and domestic relations district court judge. In each county and city in which there is located an office for a state juvenile and domestic relations district court service unit such jurisdiction shall provide suitable quarters and utilities, including telephone service, for such court service unit staff. Such county or city shall also provide all necessary furniture and furnishings for the efficient operation of the unit. When such court service unit serves counties or cities in addition to the county or city where the office is located, the jurisdiction or jurisdictions so served shall share proportionately, based on the population of the jurisdictions, in the cost of the quarters and utilities, including telephone service and necessary furniture and furnishings. All other office equipment and supplies, including postage, shall be furnished by the Commonwealth and shall be paid out of the appropriation for criminal charges. In counties and cities that provided specialized court service programs prior to July 1, 1973, which do not request the development of a state-operated court service unit, it shall be the duty of the Department to insure that minimum standards established by the State Board are adhered to, to confer with the judges of the juvenile and domestic relations district court and other appropriate officials as the case may be, and to assist in the continued development and extension of an adequate and coordinated program of court services, probation, parole and detention facilities and other specialized services and facilities to such juvenile and domestic relations district courts.
