The Pennsylvania Commonwealth Court has explicated that a de facto “in effect” taking can take place over a specified period of time. In Re Mountaintop Area Joint Sanitary Auth. v. DeLuca, No. 1318 CD 2016 (July 12, 2017) the court noted that a sewer-authority chose to operate a system in a manner which would sporadically flood the landowners home. The court found that an easement was taken for a period of nearly five years. A Board of Viewers will determine damages per the Pennsylvania Eminent Domain Code.
One week later Faherty Law Firm presented evidence that a Centre County Township effectuated a temporary de facto taking via use of the landowners property as a shortcut between two public roads.
