Built ground and a stable base

At the ZIP's center point, the USDA soil survey maps Urban land, bottomland, 0 to 3 percent slopes, rarely flooded, with the map unit identified as 100 percent urban land. For a driveway or patio, remove loose surface material and use a compacted angular-stone base separated from underlying soil with geotextile where needed.^[1]

The mapped ground elevation at the ZIP's center point is 810 feet, within the Kansas City Group, where the mapped materials are limestone, shale, sandstone, and coal. Excavation can encounter varied material, so treat excavated spoil as unsuitable for a ready-made base, use graded crushed stone for the load-bearing layer, and reserve Fill Dirt for grade adjustment.^[2],[3]

Water movement and winter exposure

The NOAA station at Kansas City Downtown AP, MO, about 3 miles away, records 38.1 inches of average yearly precipitation and 11.0 inches of average yearly snowfall. A patio base or driveway base needs to shed water and avoid trapping it in fines, while Drain Rock works well as an open-stone choice around a drain route or behind a retaining edge.^[4]

That NOAA station averages 93 days each year with lows at 32 F or colder, with a median last spring freeze of April 4 and median first fall freeze of November 2. Use a well-compacted crushed-stone base beneath hard surfaces to limit disturbance from seasonal freezing and thawing in a loose, water-holding layer.^[4]

Stone choices for finished areas

Census data show 6,449 housing units in this ZIP, and 23 percent are detached single-family houses, compared with 61 percent across Kansas City. Match the surface stone to the space's use: Crusher Run or Road Base suits a firm driveway layer, while Natural Pea Gravel or River Rock fits landscape cover where rolling stone is acceptable.^[5]

The median home construction year in this ZIP is 1979, later than the 1969 median for Kansas City. On established lots, measure the finished height of a new base before placing stone to avoid crowding existing thresholds or edging and to preserve drainage paths.^[5]

Missouri Department of Transportation names Aggregate Base Course, Type 1 Aggregate, Section 304, Missouri Standard Specifications for Highway Construction (2026) as its aggregate-base specification. That road-building standard differs from residential driveway and patio needs, where material selection depends on compaction, drainage, and the finished surface.^[6]

Garden beds over built land

The USDA mapping at the ZIP's center point classifies the ground as urban land and rarely flooded bottomland. For a new planting bed, use Top Soil where plants need rooting material, then cover it with Shredded Mulch to limit surface drying and soil splash.^[1]

The center-point geology is Pennsylvanian Kansas City Group material that includes limestone, shale, sandstone, and coal. Keep decorative stone and mulch separate from structural base stone, since a garden bed requires soil and organic cover, while compacted aggregate belongs in structural base layers.^[3]
