the Public Utilities Commission or other officer or tribunal having regulatory power over such corporation.”
The terms “real property” and “interest therein,” as used in the enabling act, are not sufficiently apt to describe the license or permit enjoyed by public utilities in maintaining their installations in public streets or ways. When the defendant Authority, with the approval of the municipal authorities, requested the plaintiff utility to relocate its facilities underground in the urban renewal area, there was no taking or invasion of a legal right, property or interest therein within a fair intendment of 30 M.R.S.A. § 4807(2). See, Maine Turnpike Authority, supra.
Electric companies operate for private gain and even though the installation and maintenance of their lines are affected with a public use, they occupy and use the soil of our public roads and highways by permission of the municipal officers under legislative enabling acts. The location of their posts, cables, wires and suitable accessory appliances has been left for determination, in the first instance, to the wise discretion of the municipal authorities to be exercised with a view to existing and probable future conditons. See, Readfield Telephone and Telegraph Company v. Cyr, 1901, 95 Me. 287, 49 A. 1047; 35 M.R.S.A. §§ 2344, 2346, 2347, 2482 and 2489. The defendant Urban Renewal Authority was created for the specific purpose of planning and effectuating the removal of slum or blighted areas in the City of Waterville with the duty to redevelop the renewal area. In so doing it was charged with the assessment of the needs required to bring about a new setting of the local municipal area with a view for a coordinated and comprehensive pattern conducive to attainment of appropriate local objectives in all aspects of municipal improvement.
We do recognize that the municipal officers of Waterville, a city with a population under 40,000 inhabitants, were not expressly empowered under 35 M.R.S.A. § 2482 to revoke the location of poles of electric companies and order their removal upon the grant of other suitable locations or of the right to the joint use of poles of other companies as provided by Section 2489 for cities with a population in excess of that number. Nevertheless, Section 2482 does give the municipal officers the power to direct or approve any alteration from an original permit, after the lines of the electric companies have been erected upon notice and opportunity to be heard. It would serve no useful purpose to delimit and compare the extent of the legislative power granted by the two sections. We stated in Maine Turnpike Authority, at pages 140 and 141 of volume 153 of the Maine reports (136 A.2d 699 at page 705) :
“The merits of the present controversy, however, concern themselves primarily with the requirements of public travel and with the police power. The authorities which follow as well as the Maine decisions which precede establish that, whatever hierarchy of privileges in utility installations there may be, the exigencies of public travel and the police power are unremittingly paramount.”
Again, at page 151 of volume 153 of the Maine reports (136 A.2d 699 at page 711), we read :
“Charters, franchises, statutory grants and permits affording the use of public ways to utility locations are subservient, expressly or by implication, in the exercise of governmental functions, to public travel and to the paramount police power and relocation of utility facilities in public streets or ways are at utility expense, a common law liability unless abrogated by the clear import of the language used in a particular instance.”
It is within the exclusive jurisdiction of the Legislature to lodge control of the roads of the State in the municipalities and to prescribe rules as to the exercise of such control. Larson v. New England Telephone & Telegraph Co., 1945, 141 Me. 326, at page 331, 44 A.2d 1, at page 4. It is
