Yes. All retaining walls in Keller should include proper drainage — a perforated pipe (French drain) behind the wall with gravel backfill. DFW's expansive clay soil holds water and creates hydrostatic pressure that can push walls over without drainage.

Keller requires stamped engineering drawings for walls over 4 feet tall, walls supporting surcharge loads (driveways, structures), and walls on slopes steeper than 3:1. Engineering costs $500-$1,500 and is included in many contractor bids.

A 40 LF retaining wall at 4 feet tall in Keller costs $6,080 at the standard natural-stone rate of $38/SF. This is based on 98 real Keller estimates. Add $500-$1,500 for engineering if the wall exceeds 4 feet in height.

Yes — every retaining wall in Keller needs drainage. Tarrant County sits on expansive clay soil that holds water and creates hydrostatic pressure behind walls. A 4-inch perforated pipe wrapped in filter fabric, set in 12 inches of gravel backfill, is the DFW standard.
