Gravel, Stone and Soil Delivery in Lee's Summit, MO

Freeze, thaw and plenty of rain

The closest NOAA normals station is Lees Summit Muni AP, MO, about 3 miles from the ZIP. It averages 38.3 inches of precipitation a year, enough that a gravel surface without a crown or a ditch will soften in the wetter weeks and rut under a loaded truck. Every project plan here should answer one question before any other: where does the water go when a long rain ends.^[1]

The airport station counts 96 days a year when the low dips to 32 F or colder. On a silty subgrade that is the number to respect, since silt draws water up toward the surface as it freezes and forms thin ice lenses that lift the ground. When those lenses melt, the soil above them turns soft and weak until it drains. A gravel drive that heaves and potholes after a cold snap is showing this cycle at work.^[1]

At Lees Summit Muni AP the median last spring freeze comes on April 7. The median first fall freeze comes on October 29. Seed lawns and set tender plants after the April date, and lay fresh mulch before the October date so roots go into the cold under cover.^[1]

The ground at the center point stands 990 feet above sea level.^[2]

Silt loam with a swelling subsoil

The USDA soil survey maps Arisburg-Urban land complex, 1 to 5 percent slopes, at the ZIP's center point. The survey counts 30 percent of the map unit as urban land, meaning paved or built over, and the Arisburg series fills 61 percent. Where the ground is still open, Arisburg soil is the one a shovel meets.^[3]

Its top mineral layer is silt loam, a smooth, floury soil that packs hard when dry and turns greasy when wet. The survey rates Arisburg somewhat poorly drained and places it in hydrologic group C, slow infiltration. Water enters this ground slowly and can sit just below the surface for days after a soaking rain, which is why spring yards on silt loam can stay squishy long after the sky clears.^[3]

Shrink-swell in the top 100 cm is rated high, at 7.2 percent. Wet Arisburg soil grows, and dry Arisburg soil pulls back and cracks. Paired with the freeze cycle, that movement explains why slabs and steps on this ground can tilt over the years, while a well-built gravel surface settles and gets raked level again.^[3]

Limestone and shale under the yard

The geologic map places the Kansas City Group at the ZIP's center point, a stack of Pennsylvanian layers made of limestone, shale, sandstone and coal. Limestone ledges in a sequence like that are hard and blocky, and a trench can stop dead on one. Shale layers between them break down into clay as they weather, which feeds the fine, slow-draining soil above.^[4]

For a buyer, the rock mainly matters on deep digs: a footing, a basement drain or a long fence line. Where a ledge sits shallow, building up a few inches with Fill Dirt or Road Base is often easier than breaking stone, and a perforated drain bedded in Drain Rock along the top of a shale layer catches the seep that tends to run along it.^[3],[4]

A driveway that rides out frost heave

Strip the dark topsoil and roots until you reach firm silt loam, then shape the subgrade with a crown so water sheds to both sides. Roll out a woven fabric across the footprint. On silty, frost-prone ground the fabric keeps the base clean, so it stays open enough to drain instead of turning into a silty paste that holds water and heaves.^[1],[3]

Build the base in two courses. A lower layer of 1-1/2" Crushed Gravel or #4 Crushed Stone gives a coarse, open bed that drains fast and resists the lift from ice below. Above it, Road Base compacted in thin lifts fills the gaps and sets up firm. Crushed Concrete can stand in for that upper layer. Finish with 3/4" Crushed Stone or Driveway Gravel. Run a ditch of #57 Crushed Stone along the low edge, and with 38.3 inches of yearly rain at the station, give it an outlet so water leaves the site rather than pooling at the end of the drive.^[1],[3]

Every gravel drive on swelling, frost-prone silt loam needs a little care once the ground thaws. Walk it after the April freeze date, rake loose stone back into the wheel tracks, and fill any soft dips with fresh 3/4" Crushed Stone. Catching a low spot early stops a puddle from forming there, and a puddle is where the next round of heaving starts.^[1],[3]

#57 Crushed Stone or #67 Stone for a drain line

These two stones show up in most French drain and footing drain plans, and the choice comes down to the gap size you want. #57 Crushed Stone runs a little larger, with pieces about the size of a grape to a walnut. Its wide gaps pass water fast and resist clogging, so it works well in the main body of a drain trench on slow, silty ground where a lot of water arrives at once.^[1],[3]

#67 Stone carries a mix of that size and smaller chips, so it packs a little tighter and gives a smoother top. It suits the bedding around a pipe, a walkway that doubles as a drain path, or the top layer of a trench that people cross on foot. On swelling silt loam, either stone should sit inside a fabric wrap, because loose silt washing into the gaps is what ends a drain's useful life. A simple build uses #57 Crushed Stone around and below the pipe and a cap of #67 Stone where the trench meets the lawn.^[3]

Silt loam can grow a fine garden once its surface stays loose. Spread a layer of Compost over new beds each year and fork it in, or build raised beds filled with Garden Soil. Brown Shredded Mulch or Wood Chips on top stop rain from sealing the surface into a crust. Near paved areas, where runoff gathers, a border of River Rock gives that water a place to slow down before it reaches the plants.^[3]
