Ground, water and winter in Woodson Terrace
Loess over clay is the rule across St. Louis County, and the county soil survey warns that local streets need adequate base material plus side ditches and culverts because of low strength and frost action. Winters here cycle above and below freezing for months. We grade for water, compact rock, then pave.
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 Woodson Terrace estimate is sized to the soil, the traffic and the drainage on your property.
