Sandy loam on gentle mapped slopes

At the ZIP's center point, the USDA soil survey maps the Wedowee-Urban land complex on 2 to 6 percent slopes, with 40 percent of that map unit classified as urban land. For a driveway or patio, keep the prepared base distinct from built or disturbed ground so the stone layer has a uniform bearing surface.^[1]

Wedowee makes up 55 percent of the mapped unit, and the soil is rated well drained. A compacted layer of angular crushed stone is a suitable choice where a firm driveway or patio base needs particles that lock together.^[1]

The top mineral soil is sandy loam in hydrologic group B, which has moderate infiltration. With low shrink-swell measured at 2.5 percent in the top 100 cm, use a geotextile beneath a stone base when separation from the native soil is needed.^[1]

Granite mapped below the surface

The mapped geologic unit is Foliated to Massive Granitic Rock, and its listed rock type is granite. During excavation for a patio, walk, or bed edge, remove loose rock and create an even subgrade before placing base stone, drainage stone, or Top Soil.^[2]

Water movement through stone layers

The NOAA station at Raleigh State Univ, NC, about 8 miles away, reports 49.4 inches of average yearly precipitation and 4.5 inches of average yearly snowfall. Use open Drain Rock or #57 Stone to move water away from the edge of a hard surface, since fine material can hold moisture.^[3]

At that NOAA station, lows reach 32 F or colder on 57 days in an average year, with the median last spring freeze on March 28 and the median first fall freeze on November 8. Avoid leaving water trapped in a base or drain layer through freezing weather, and use Shredded Mulch over a finished garden bed to cover the soil surface.^[3]

Housing context and material records

Census data lists 21,386 housing units in the ZIP, with 49 percent detached single-family houses, compared with 44 percent across Raleigh. Housing counts and shares provide context, while driveway, patio, drainage, and bed materials should be selected from the ground and water conditions.^[4]

The North Carolina Department of Transportation names Aggregate Base Course, Section 520, Standard Specifications for Roads and Structures (January 2024) as its road-building specification. For a residential base, set the layer plan by the project's support and drainage needs rather than treating that road standard as a product label.^[5]

American Rock Supply order records for North Carolina list Driveway Gravel and Crusher Run most often over the last 24 months, with a median order size of 6 tons. This order record describes customer purchases rather than material selection for a particular project.^[6]
