The methods, priced apart by frame
| Method, as listed | Frame A reading | Frame B reading |
|---|---|---|
| Regrading | counted by the clearing, excavation, fill, and topsoil lines below | no per-unit method line; project totals only |
| Erosion-control grid and matting | slope erosion control grid at $1-$2 per square foot | no per-unit method line printed in this frame |
| Hydroseeding and sod cover | sod at $1-$2 per square foot; no separate hydroseeding line printed | no per-unit method line printed in this frame |
| Drainage-line work, as a cost factor | no separate drainage line printed in this frame | no separate drainage line printed in this frame |
Each reading is one frame's own counting, and the job on every row stays residential slope repair. Frame B carries no per-unit method lines, so a method name reads there as a project-total reading alone.
The regrading lines behind the first method, as reported
| 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 |
The regrading method prices out of the Frame A lines above, in that frame alone. Frame B prints no regrading line; its project readings stand below.
The Frame B project readings behind every method, as reported
| 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, high end | some as low as, others up to | $700; $5,000 |
Those totals are the only Frame B readings on this page, standing behind each method name apart from the Frame A unit lines. No Frame B total is added into a Frame A reading.
Methods priced apart, neighbours named apart
A method line answers the method question only inside its own frame. The drainage-line row reads as a cost factor beside the printed lines, with French drains sold as their own purchase named apart from it. Named apart, never a row here: retaining walls sold as structures, flat yard leveling with no failed slope, seawalls and bulkheads, and foundation repair — and the job here stays residential slope repair.

How is drainage-line work priced on this page, as reported?
As a cost factor alone. Neither frame prints a separate drainage-line figure: Frame A prints its unit lines, land clearing at $1,200 to $8,000 per acre among them, and Frame B prints project totals, $700 to $5,000. French drains as their own purchase are named apart.
Are retaining walls, flat yard leveling, seawalls, or foundation repair priced in this guide?
No, head-on: this guide prices residential slope repair methods alone. Retaining walls sold as structures, flat yard leveling with no failed slope, seawalls and bulkheads, French drains as their own purchase, and foundation repair are named apart.
