What shapes a South Dakota project

Pierre shale soilAmong the most expansive in the US (central SD)

Engineered foundations + drainage essential for additions. The top structural surprise in the region.

Tornado + hailFrequent tornadoes and severe hail

Safe rooms + Class 4 roofing. Most roof claims are hail; impact shingles earn discounts.

Frost + wind~42-48 inch frost; very windy

Deep footings; wind-rated doors + fastening. Drifting snow affects design.

Black HillsHeavier snow + steep terrain

Verified roof load calcs; hillside drainage + access considerations.

Basement egressRequired for habitable basement rooms

Plan egress into any basement finish. Basements are storm refuge.

Frost line depth42-48 inches

Deep footings. Frost-heave on older walkways frequent.
