Bulk Aggregates near Oklahoma City, OK, 73165

Mapped water at the center point

The USDA soil survey maps the center point as Water, and the mapped geologic unit there is also water. That mapping does not identify a usable soil texture for choosing a driveway or patio base, so choose angular crushed stone for a locked base and open stone where drainage is needed.^[1],[2]

Ground elevation at the ZIP center point is 1,190 feet. For a hardscape base near a wet edge or low area, a geotextile keeps soft underlying material from mixing into the angular base stone.^[3]

Rainfall favors open drainage paths

The NOAA station at Norman 3SSE, OK, about 12 miles away, records 37.6 inches of average yearly precipitation. Drain Rock or #57 Stone leaves open spaces for water beside a foundation or retaining edge and beneath a surface that needs to shed runoff.^[4]

That station averages 4.1 inches of snowfall each year. Snowmelt and rain make fines alone unsuitable in a drainage path because fines hold water while clean drainage stone stays more open.^[4]

A base for freeze-season movement

At the NOAA station, lows reach 32 F or colder on 76 days in an average year. A driveway or patio base benefits from compacted angular material such as Crusher Run or Road Base, which locks together better than round Natural Pea Gravel.^[4]

The median last spring freeze is April 3, and the median first fall freeze is November 3. Where water can reach a base before freezing, use a drainage layer of open stone below or beside the finished surface rather than making the drainage layer from Stone Screenings.^[4]

Material choices for detached home sites

Census data count 2,958 housing units here, with 81 percent detached single-family houses, compared with 67 percent across Oklahoma City. For an individual home project, keep surface material separate from structural base material: use crushed aggregate below a drive or patio and reserve decorative River Rock or Natural Pea Gravel for areas without vehicle loading.^[5]

The median home construction year is 2002 here, compared with 1982 across Oklahoma City. When renewing an existing drive or patio edge, remove soft or mixed material before placing a new compacted crushed-stone base so the surface has a consistent support layer.^[5]

Owner occupants live in 95 percent of occupied homes in this ZIP. For garden beds around a residence, use Top Soil as a planting medium that Shredded Mulch can cover, limiting drainage stone to places where moving water is the goal.^[5]

The Oklahoma Department of Transportation names Aggregate Base, Type A, Section 303, Standard Specifications for Highway Construction (2019) as its aggregate-base specification. That is road-building terminology, so select private driveway and patio material based on whether the layer must compact or drain, or will be the finished surface.^[6]
