| Frame | What it counts | 2026 band |
|---|---|---|
| Frame A | excavation, per cubic yard | $2.50-$15 |

This cluster prices residential slope repair alone: an eroded, slumped, or washed-out slope on a residential lot repaired as one purchase. Named apart, never a row here: retaining walls sold as structures, flat yard leveling with no failed slope, seawalls and bulkheads, French drains and drainage systems sold as their own purchase, and foundation repair.
Frame A lines, as reported: the work by its per-unit lines
| Frame A line, as published | Reading | 2026 band |
|---|---|---|
| Land clearing | per acre | $1,200-$8,000 |
| Excavation | per cubic yard | $2.50-$15 |
| Fill dirt | per cubic yard | $5-$25 |
| Topsoil | per cubic yard | $10-$50 |
| Slope erosion control grid | per square foot | $1-$2 |
| Sod | per square foot | $1-$2 |
| Retaining wall | per square foot, named-apart cost-factor line, this frame alone | $35-$65 |
Frame A, counted by the unit: each row is one printed reading, not parts of one printed total. The retaining wall row stands in this frame alone as a named-apart cost factor.
Frame B lines, as reported: the finished project by its totals
| Frame B line, as published | Reading | 2026 band |
|---|---|---|
| Yard leveling average | per square foot on average | $1-$2 |
| Average project | per finished project | $2,159 |
| Most projects | per finished project | $1,097-$3,487 |
| Low end | some projects as low as | $700 |
| High end | other projects up to | $5,000 |
Frame B, counted by the finished project: those readings stand inside this frame alone, with no per-unit method lines at all. No Frame B line is added into a Frame A total.
The neighbours, differentiated, and the local fit stated honestly
The retaining-wall hub prices retaining walls sold as structures. Seawalls and bulkheads, French drains as their own purchase, and foundation repair are priced in their own clusters. This cluster prices the failed residential slope alone, apart from the retaining-wall bands. The local fit is honest and narrow: Orange County's hillside neighborhoods are the real pool, a narrower, high-ticket pool than the flat-lot clusters, never a county-wide volume claim.
