BUILDING IN CEDAR RAPIDS: WHAT TO EXPECT
Soil & Slab Notes — Linn County
Linn County soils are predominantly Kenyon and Clyde loams — productive glacial till soils with good structure and moderate drainage. Most upland sites support a standard 4–5" monolithic slab without extraordinary preparation. Low-lying sites near the Cedar River (which flooded severely in 2008 and again in 2016) require careful attention to floodplain mapping and finished floor elevation. Cedar Rapids city ordinance requires finished floor elevation to be at least 1 foot above the base flood elevation on any FEMA-mapped parcel.
