Court hears arguments on CEI's alleged negligence in flood incident

In a tense courtroom filled with anticipation, the Massachusetts Supreme Judicial Court convened on May 5, 2025, to hear oral arguments in a pivotal case concerning alleged negligence related to flooding. The case centers on claims against Comprehensive Environmental, Inc. (CEI) and the Town of Barnstable, with the plaintiff asserting that the design and maintenance of a stormwater management system led to significant property damage.

The plaintiff's attorney argued passionately that while CEI does not control the weather, they are responsible for managing the consequences of rainfall. He contended that the flooding was a direct result of CEI's negligent design and failure to maintain the stormwater system, which he claimed was undersized and improperly managed. He pointed to a specific rain event in February 2017, where 2.92 inches of rain fell within three hours, leading to flooding that had not occurred on the property for nearly a decade prior to the installation of the system.

In response, CEI's counsel countered that the plaintiff's claims lacked the necessary expert testimony to establish a direct link between the design of the stormwater system and the flooding. He emphasized that the plaintiff had not demonstrated that CEI's design failed to meet professional engineering standards, a critical element in proving negligence. The attorney also noted that the flooding incident was isolated, occurring two years after the system's installation, and argued that the plaintiff had waived certain arguments by not addressing them in previous briefs.

The Town of Barnstable's attorney reinforced the notion of governmental immunity under the Massachusetts Tort Claims Act, asserting that the town had not owned the property at the time of the flooding and that the claims were based on design rather than maintenance. He highlighted that the plaintiff's testimony indicated the flooding was not due to maintenance failures but rather the design itself.

As the justices listened intently, they posed questions that probed the nuances of negligence, causation, and the applicability of legal immunities. The discussions revealed a complex interplay between engineering standards, municipal responsibilities, and the legal thresholds necessary to hold entities accountable for environmental management.

The outcome of this case could set significant precedents regarding liability in municipal engineering projects and the standards required for proving negligence in similar future cases. As the court deliberates, the implications for property owners and municipalities alike hang in the balance, underscoring the critical importance of effective stormwater management in an era of increasingly unpredictable weather patterns.
