Why Highland Park homes face basement risk

Basement flooding in Highland Park is mostly a function of housing age and soil. Older homes were built with clay drain tiles that crack and clog over decades, and the dense clay across southeast Michigan holds water against foundations rather than letting it drain. Much of Highland Park also runs on combined sewers, where storm runoff and sanitary sewage share one set of pipes, so a hard rain can back sewage up through a floor drain, and a backwater valve often matters more here than any wall treatment. Communities in Highland Park's risk band were among those hit hardest when the June 2021 storms put tens of thousands of metro Detroit basements underwater and triggered a federal disaster declaration.

What to do about it

1. Take preventative steps before the next heavy rain. Homes in this band have the highest documented exposure in the metro.
2. Test your sump pump and add a battery backup, power fails in the same storms that flood. See what actually keeps a basement dry.
3. Check for a backwater valve if your home predates the 1970s; sewer backup is the costliest version of basement flooding.
4. Extend downspouts at least six feet from the foundation and keep gutters clear.
