Basement waterproofing across Dakota County.
Eagan, Mendota Heights, West St. Paul, South St. Paul, Inver Grove Heights. River-bluff geology, clay-heavy soils, and three eras of housing stacked into the same neighborhoods.
Mendota was first. The geology has been arguing with the basements ever since.
Mendota Heights was the site of the first non-native settlement in the state, with Henry Sibley building his stone house there in 1838. The neighborhoods that grew out of that early settlement, the Mendota bluffs, west into South St. Paul, sit on a foundation profile that very few other Twin Cities cities match. River-bluff clay till, with isolated pockets of perched groundwater that move with the freeze-thaw cycle.
South St. Paul and West St. Paul were industrial cities tied to the stockyards through most of the 20th century, and their housing stock skews older and denser than the suburbs around them. Eagan and Inver Grove Heights grew up later, mostly post-1970 subdivision construction on graded fills with their own particular drainage signatures.
Dakota County has more elevation change per square mile than any of the other Twin Cities counties. That changes the water and changes the fix.
The practical implication: surface drainage matters here in a way it does not on the flatter ground to the north. A basement at the bottom of a Mendota Heights cul-de-sac is gathering water from a much bigger catchment than a basement on a Plymouth flat lot. We size the system to the catchment, not to a generic linear footage.
