Evanston Ins Co. v. Tex. Concrete and Sand Gravel, Inc., No. 4:20-cv-00103 (S.D. Tex. Aug. 30, 2022) is a coverage dispute over Evanston Insurance Co.’s (“Evanston”) duty to defend and indemnify Texas Concrete Sand and Gravel, Inc. (“Texas Concrete”) and Apcon Services, LLC (“Apcon”) (collectively, the “Insureds”) for their contributions to the degradation of the waterways and retention lakes built to control flooding in the Houston area. On August 3, 2022, Magistrate Judge Yvonne Y. Ho recommended that Evanston’s motion for summary judgment be denied. On August 30, 2022, District Court Judge Alfred H. Bennett adopted Judge Ho’s Memorandum and Recommendations.

In 2017, Hurricane Harvey caused significant flooding of the Houston area, which resulted in large-scale property damage. The underlying lawsuits alleged that, since 1954, Lake Houston’s waterways sustained a steady decline in capacity because of the release of materials into the waterway system. The Insureds allegedly contributed to the decline by allowing “materials and substances” (such as processed water, silt, sand, sediment, dirt, rock, and aggregate) to run off their privately controlled properties and into the Houston waterways. The reduced capacity, allegedly caused in part by the Insureds, exacerbated the flooding after Hurricane Harvey hit, increasing the damage from the hurricane.
