The case of Arriola v. City of San Clemente, et al. arises from a dramatic slope failure that occurred on January 6, 2011. The slope that failed is within Cascadita Canyon and is immediately adjacent to 12 single family residences that front on Via Ballena. The slope failure immediately undermined and eliminated lateral support to the backyards and houses of those 12 homes. The slope that failed descends to the bottom of Cascadita Canyon and both the bottom of the canyon and the slope were owned by Shorecliffs Golf Course. The 5th and 6th holes of the golf course were located within the canyon. Via Ballena and all of the utilities in that area (water supply lines, storm drain lines, sewer lines) are owned and maintained by the City.
