Ground, water and winter in Lake St. Louis
The county soil survey notes some upland soils lack strength for traffic without added crushed rock in the road base, and clayey subsoils here shrink and swell with moisture. Lakeside lots add runoff to that. Freeze-thaw winters widen whatever water gets into. We grade to drain, replace soft ground and compact base rock in layers.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
Compacted asphaltTypically 2 to 3 in. for a car drive
Stone baseTypically 4 to 8 in., compacted
Drive on itUsually 2 to 3 days, longer in heat
First sealcoatTypically 6 to 12 months after paving
Typical ranges. Your Lake St. Louis estimate is sized to the soil, the traffic and the drainage on your property.
