Plaintiff's bill alleges defendants, in operating their stone quarry, located on land abutting on the western side of Southern Avenue, in plaintiff city, have deprived that avenue of necessary lateral support, thus causing the sinking of the street's surface, and asks for an injunction, restraining the operation of the quarry, and a decree commanding defendants to restore the highway to its proper condition, and secure its support by a suitable retaining wall. The court below dismissed the bill and the city appealed.
Southern Avenue was originally a township road, and, subsequent to that territory becoming part of plaintiff city, was, by ordinance approved April 1, 1886, relocated and established from Wyoming Street to Boggs Avenue, with a width of 40 feet, and later opened as of this width and damages and benefits assessed and paid. By ordinance of June 29, 1891, the location of the street was again changed by altering its direction, and moving its junction with Boggs Avenue 70 feet eastward of the centre line as fixed by ordinance of April 1, 1886. The ordinance of 1891 contained a general clause repealing provisions of all inconsistent ordinances. Subsequently in 1897 a sewer was laid in the relocated street by the city and in 1899, under the provisions of an ordinance approved March 31, 1898, the street as relocated was graded, paved, and curbed, with a driveway twenty-four feet in width, and sidewalks of eight feet in width.
In its original location, Southern Avenue ran along the side of a steep hill, at the foot of which is a stone quarry operated by defendants. In relocating the street under the ordinance of April 1, 1886, the bank on the east side was cut into, and a considerable portion of the excavated earth dumped on the westerly side of the street on defendant's property. The completed improvement *Page 590 left a vacant strip of ground varying from 35 to 70 feet in width between the relocated avenue and defendant's original property line; this strip included a portion of the old roadbed, which the court below found the city abandoned at the time it relocated the avenue, by moving it east of its original location. In making the improvement, earth thrown over the bank on defendant's property covered a hillside spring, situated midway between the street and the quarry, obstructing its flow of water and partially concealing a near-by spring house. During several years following the improvement of the street, slides occurred from time to time on defendant's property, apparently due, in part at least, to water flowing from the closed spring percolating through the soil and causing the hillside earth to loosen and slip. At this point the gradual sinking and slipping of the surface finally extended across the former bed of the abandoned highway causing damage to the west side of the avenue as relocated and improved. Expert witnesses testified that the fact that the slipping was confined to earth above the spring, indicated the closing of the natural channel of the water from the spring, compelling it to seek other means of outlet, and in so doing to percolate through and saturate the soil, affecting its cohesion to such extent as to increase its tendency to slide.
The city claims it retains title to the abandoned bed of Southern Avenue, contending the ordinance of June 29, 1891, is irregular and void, so far as it attempts to vacate the street as originally laid out by ordinance of April 1, 1886, and that the mere change in location of the old road, did not amount to a surrender of the ground included in its bed. Assuming, for the present, the proceedings to be irregular, it does not follow the conclusion reached by the court below was erroneous. No objection to the validity of the city's action was raised by abutting owners, and heretofore all parties concerned, including the municipality, treated the old road bed as abandoned, and reverting to the abutting *Page 591 owners. The strip mentioned has been assessed for the purpose of taxation by the city, against defendants and their predecessors in title. Although assessment and payment of taxes on property is not proof of title, yet, under the circumstances here involved, it should be treated as a recognition by the city of title in the abutting owners, and evidence of intent on the part of the city to abandon any title it had to the old location; add to this, the further circumstance of making permanent improvements on the new location by the city, with surrender of control over the old roadbed, and we think a situation was created ample to warrant the court below, at least in these proceedings, in reaching its conclusion that a vacation of the old street bed was intended by the city, and title to the vacated ground consequently reverted to the abutting property owners: Mill Creek Twp. Road v. Reed, 29 Pa. 195. Having relinquished its rights in the bed of the vacated highway for many years, the position of the city in now attempting to assert ownership, for the sole purpose of compelling the abutting owners to furnish support to the hillside, is not such a contention as calls for favorable consideration by a court of equity. The municipality may properly be held estopped by its conduct from asserting title to what it had apparently abandoned for a long period of years: Pittsburgh v. Pittsburgh West Virginia Ry., 283 Pa. 196.
No suggestion appears that the city undertook to appropriate land beyond that actually necessary for the street bed, for any purpose, consequently it had no right to deposit earth excavated on the east hillside of the street, on defendant's property abutting the lower opposite or west side. While apparently no objection was made to such action, the city did not, by mere inaction on the part of the owner, acquire a right of support for the additional burden thus cast upon the adjoining land. Furthermore, the evidence warrants the conclusion that the immediate cause of the slide was not the operation of defendant's quarry, which in fact had not *Page 592 approached toward the hillside for a number of years, but the extra burden placed on the land by depositing thereon the excavated earth from the new location of the street, plus the covering of the spring by that material and consequent percolation of its water through, and saturation of, the newly deposited ground, thus increasing its tendency to slide. The direct responsibility for the damage to Southern Avenue resulting from the sliding of earth above defendant's quarry, placed there by the city at the time of improving the street, accordingly rests with the city, and it cannot now compel defendants to assume the burden of a condition for which they were not responsible.
The decree of the court below is affirmed at plaintiff's costs.
