Gravel, Stone and Sand near Los Angeles, CA, 90013

Drainage stone for a slower-draining soil

The USDA soil survey classifies the center point as somewhat poorly drained. Use open Drain Rock where water needs a route below a patio base, along an edge, or beneath a gravel surface.^[1]

The top mineral layer is sandy loam, and the soil is in hydrologic group B with moderate infiltration. Keep drainage layers free of fines when the goal is to preserve open spaces between stones for water movement.^[1]

The top 100 cm has low shrink-swell, with linear extensibility of 1 percent. A compacted angular-stone base provides a stable bearing layer beneath a driveway or patio while separating surface material from the soil.^[1]

Base choices around built surfaces

At the center point, the USDA soil survey maps Urban land, commercial, 0 to 5 percent slopes. On a relatively gentle work area, shape the base to direct water toward a planned outlet instead of letting it sit against the finished surface.^[1]

Urban land accounts for 90 percent of the mapped unit at the center point. Where a new gravel area meets paving or a structure, use a defined edge to keep loose surface stone in place.^[1]

The main named soil series is Hueneme, but it represents 1 percent of the mapped unit. For an excavation that reaches native material, a geotextile keeps clay or soil from mixing into an angular crushed-stone base.^[1]

Climate and property context

The NOAA station at Los Angeles DWTN Usc Campus, CA, about 1 mile away, records average yearly precipitation of 14.2 inches. Drainage stone remains useful beneath hardscape because a somewhat poorly drained soil can hold water after rain.^[1],[2]

The same NOAA station reports 0 days each year when the low reaches 32 F or colder. Frost-driven base movement is not a material-selection concern indicated by that station record.^[2]

Census data lists 10,375 housing units in this ZIP, with 1 percent detached single-family homes, compared with 36 percent across Los Angeles. Select driveway, patio, or garden-bed material for the actual work area rather than assuming a detached-home layout.^[3]

The median construction year is 1944 in this ZIP, compared with 1965 across Los Angeles, and 8 percent of occupied homes are owner-occupied. When replacing an existing patio or drive, remove loose material before placing a fresh compacted base and chosen surface stone.^[3]

Caltrans names Class 2 Aggregate Base, Section 26-1.02B, Standard Specifications (2026) as a road-building standard. In California orders over the last 24 months, Driveway Gravel was the material ordered most often, and the median order size was 8 tons.^[4],[5]
