Due to annexations by Fox Crossing, Wisconsin, Clayton sued Fox Crossing in late 2017 and was subsequently sued by the village for a wastewater collection settlement with the Wisconsin Department of Natural Resources.[4] [5] The town reached a water deal with the city of Appleton in 2018 but negotiated with Fox Crossing for a new deal in 2020, paying the village $11.5 million in exchange for sewer and water in addition to an agreement not to annex any part of the town for ten years.[6]
