Clinton Township is one of Macomb County's most populous communities, characterized by post-WWII and 1970s–1990s suburban housing with full basements. The Macomb County combined sewer system — shared with Sterling Heights, Warren, and downriver communities — is chronically undersized for modern storm events and regularly overflows into basements during heavy rain. The August 2014 event flooded over 75,000 basements across Macomb County in a single afternoon, costing the county over $200 million — Clinton Township was among the hardest hit. The township sits on flat glacial lake-bed topography with minimal natural drainage gradient, meaning water moves slowly during heavy events. Frozen pipe risk is significant: the township averages 15+ days per year below 0°F, and many 1960s–1970s homes have uninsulated exterior wall plumbing.
High-risk neighborhoods
Metro Parkway corridor (highest commercial density, sewer overflow impacts mixed-use basements); Canal Road areas (Clinton River proximity, Zone AE portions); newer subdivisions near Hall Road (lower flood risk but sump pump dependency in wet seasons)
