River rock for drainage in San Marcos: dry creek beds and French drains

Heavy rain can move a lot of water across a San Marcos yard in a short time. A dry creek bed or French drain gives it somewhere to go.

Dry creek beds

Dig a shallow swale along the natural flow line, lay fabric, then place larger river rock on the sides and smaller rock in the channel. Depths of 3–4 inches of rock are typical.

French drains

Wrap perforated pipe in fabric inside a gravel-filled trench. Washed, clean stone drains better than material with lots of fines.

How to work out how many tons you need

Multiply length × width in feet by depth in inches, then divide by 324 to get cubic yards. Most gravel, base and sand weigh roughly 1.3–1.5 tons per cubic yard; soil and mulch are lighter. Our materials calculator does the math with the real density of each material and rounds up to the order minimum, so you don't come up short on delivery day.

Truck access in San Marcos

A loaded dump truck needs about 12 feet of width and 14 feet of overhead clearance to reach the drop spot. Watch for low oak limbs, soft lawns after rain, septic fields and irrigation lines. Add a note to your order with gate codes or where you want the pile, and the driver will follow it.
