Gravel, Stone and Sand near Cape Coral, FL, 33914

A stable base on sandy ground

At the ZIP's center point, the USDA soil survey maps Matlacha gravelly fine sand, limestone substratum-Urban land complex, on slopes of 0 to 2 percent. That nearly level, sandy ground needs a compacted angular-stone base beneath a driveway or patio instead of a loose round-stone layer for support.^[1]

Matlacha accounts for 48 percent of the mapped unit, while urban land accounts for 40 percent. Where native soil remains exposed for a base excavation, use geotextile beneath Crusher Run or Road Base to keep the sandy soil and aggregate layers separate.^[1]

Drainage beneath driveways and patios

The USDA soil survey classifies the soil as somewhat poorly drained, even though it is in hydrologic group B with moderate infiltration. Use a free-draining stone layer where runoff needs a path below a paved surface, and keep fine-rich material out of that drainage layer.^[1]

Lithic bedrock occurs at about 48 inches, and the top soil has low shrink-swell of 0.3 percent. The restrictive layer favors handling water at the surface and within the aggregate base instead of deep drainage, while the low shrink-swell supports a consistently prepared base.^[1]

Stone choices for the local sediments

The mapped geologic material consists of shelly sediments with sand, limestone, and clay. For a load-bearing driveway or patio foundation, use crushed angular stone instead of rounded gravel because the pieces lock together under compaction.^[2]

Ground elevation at the ZIP's center point is 10 feet. A defined base edge and a surface that directs water toward a drainage path protect stone from standing water at this low elevation.^[3]

The NOAA station at FT Myers Page FLD AP, FL, about 10 miles away, records average yearly precipitation of 57.4 inches. Choose Drain Rock or another open stone for drainage zones, and reserve finer aggregate such as Crusher Run for compacted base areas rather than water-collection areas.^[4]

Garden beds and frost exposure

The top mineral soil layer is gravelly fine sand. For a planted bed, add Top Soil as the growing layer instead of using the native gravelly sand alone, then cover it with Shredded Mulch to retain moisture near plants.^[1]

The NOAA station records 0 days each year with lows of 32 F or colder, with median freeze dates of January 16 and January 13. Material planning focuses on rain drainage and moisture retention instead of selecting a base for repeated freeze-thaw movement.^[4]
