City of Oroville v. Superior Court of Butte CountyAnnotate this Case
The Supreme Court reversed the judgment of the court of appeal finding the City of Oroville liable in inverse condemnation for property damage suffered by a dental practice when raw sewage began spewing from the toilets, sinks, and drains of its building, holding that where the dentists did not install a legally required backwater valve on their premises the City was not liable for the property damage.
The dentists argued that the City was legally responsible for the property damage because it was caused by the sewer system's failure to function as intended. The City argued in response that the damage occurred because the dentists failed to install the backwater valve that would have prevented sewage from entering their building in the event of a sewer main backup. The trial court concluded that an inverse condemnation had occurred. The court of appeal affirmed. The Supreme Court reversed, holding that the damage was not substantially caused by the sewer system when the dentists failed to fulfill a responsibility to install a backwater valve that would have prevented or substantially diminished the risk of the mishap that occurred in this case.
