We obtained summary judgment in the Westmoreland County Court of Common Pleas in favor of our clients in a dispute over alleged excess water runoff. Our clients, a married couple, were sued by their neighbors for claims related to water runoff due to the installation of gutters and downspouts on a shed near the property line. We effectively argued for summary judgment on the plaintiffs’ injunction, trespass, nuisance and negligence claims, demonstrating that the plaintiffs lacked the necessary expert testimony to substantiate their case as required under Pennsylvania law. Additionally, the plaintiffs’ negligence claim was barred by the two-year statute of limitations, which had expired at least six years before the suit was filed.
