Eden Prairie developed fast and Purgatory Creek is paying for it. How rapid development created a documented stormwater overflow crisis, what sandy soils and clay soil zones mean for foundations, and why your housing era determines your risk profile.

Plymouth sits at the headwaters of Bassett Creek with Medicine Lake receiving drainage from 11,000+ acres across five cities. Plus: why the city’s dominant 1980s housing stock is hitting a critical sump pump and plumbing age threshold.

Minnetonka updated its floodplain maps in 2023 for the first time since 1999. What that means for your home, how Lake Minnetonka affects your water table, and why the city’s 252 stormwater ponds matter for adjacent properties.
