Pennsylvania Statutes Title 11 Pa.C.S.A. Cities § 12988. Streets more than half of whose width is within city

(a) Authority to improve entire street.--Whenever any street, more than one-half the width of which is within the limits of the city, shall divide the city from any other municipal corporation, the street may be improved by the city in the same manner as if the street were entirely located within the limits of the city.

(b) Assessment.--The property, within or outside the city, that abuts the street and benefits from the improvements may, for a depth of 150 feet plus one-half the width of the street measured from its center line, be assessed for any and all municipal improvements to or on the street in the same manner as the property would be assessed under the provisions of this chapter if it were entirely located within the limits of the city.
