What affects the cost in Milwaukee
Climate: ERA5 reanalysis via Open-Meteo
We do not have a reliable USDA soil reading for Milwaukee yet, because the national survey leaves parts of this urban area unmapped. Regionally the ground here trends toward glacial till, but soil varies lot by lot, so a contractor's on-site look matters more than any city-wide figure.
Permits in Milwaukee
Structural foundation work and exterior excavation generally require a permit, while interior waterproofing and minor crack sealing often do not. Requirements and fees are set locally, so confirm with your city or county building department before work starts.

What puts water in a Milwaukee basement
Milwaukee takes about 37.7" of rain in an average year and runs through roughly 73 freeze-thaw cycles (ERA5 reanalysis), the ordinary combination of water in the ground and pressure against the wall that keeps basements and foundations working here.
And it is not only a floodplain problem: in Milwaukee County, about 37% of basement flood-insurance claims were filed outside the mapped flood zone, and because flood insurance is mostly bought only inside that zone, the real outside-the-zone share is almost certainly higher.
