BUILDING IN JEFFERSON CITY: WHAT TO EXPECT
Soil & Slab Notes — Cole County
Jefferson City sits on the Missouri River bluffs in Cole County, where Menfro silt loam covers the upland ridges and Gasconade soils thin out over Ordovician dolomite bedrock on the steeper slope positions. The city's hilltop and ridge terrain is well-drained with moderate bearing capacity — upland parcels away from the river bluffs are good candidates for standard slab construction. Budget for a 5" reinforced slab with perimeter beam; ridge-top parcels with bedrock near the surface may need a modified footing design. Bottomland and river-terrace parcels near the Missouri River require careful floodplain elevation review. Frost depth for Cole County is approximately 18–20 inches.
