Lower town and the hill

North Mankato has a lower section on the river plain and neighborhoods up on the hill above the valley wall. The lower part sits behind the flood barriers that the Army Corps of Engineers built through the 1970s and 1980s; residents there tend to call about groundwater seepage and sump capacity. Homes on the hill more often see cracks in poured walls, settled backfill sloping toward the house, and window well leaks.

On the slope between

Houses along the valley wall itself can get runoff from above and groundwater from below. Grading, gutters sized for the roof, and drain tile on the uphill side are frequently part of the same job.
