Why the base matters in Lake Timberline
The lakes here are reservoirs built in creek valleys, so this ground moves water constantly. St. Francois County soils run thin over igneous rock on the knobs and red cherty clay on the dissected hills, and NRCS notes low strength for vehicle traffic on several soils, correctable with suitable base. Freeze-thaw winters do the rest.
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 Timberline estimate is sized to the soil, the traffic and the drainage on your property.
