Excavation, fill, and topsoil lines, as reported
| Cost line, as published | Reading | 2026 band |
|---|---|---|
| Excavation | Frame A, per cubic yard | $2.50-$15 |
| Fill dirt | Frame A, per cubic yard | $5-$25 |
| Topsoil | Frame A, per cubic yard | $10-$50 |
| Excavation, fill, or topsoil, per-unit | Frame B | no figure printed |
The line figures sit as readings inside Frame A alone. None is added to a project total, and Frame B prints no unit figure for any of the three lines.
The project totals behind the lines, as reported
| Cost line, as published | Frame | 2026 reading |
|---|---|---|
| Average project | Frame B | $2,159 per finished project |
| Most projects | Frame B | $1,097-$3,487 per finished project |
| Finished project average | Frame B | $1-$2 per square foot on average |
| Land clearing, per acre | Frame A | $1,200-$8,000 per acre |
Frame B prints finished-project totals and Frame A prints per-unit and per-acre readings, apart from one another. The Frame B square-foot average counts the whole project, not any single cover line.
The cover and access lines, as reported
| Cost line, as published | Frame | 2026 reading |
|---|---|---|
| Slope erosion control grid | Frame A | $1-$2 per square foot |
| Sod | Frame A | $1-$2 per square foot |
| Retaining wall, cost-factor line | Frame A | $35-$65 per square foot, named apart |
| Low end, high end | Frame B | $700; up to $5,000 |
| Cover or access line | Frame B | no figure printed |
The cover and access lines count inside Frame A alone, and the retaining wall line stands there as a named-apart cost factor. Named apart, never a line here: retaining walls sold as structures, flat yard leveling with no failed slope, seawalls and bulkheads, French drains as their own purchase, and foundation repair.

Frequently asked questions
What is the priced line in a slope repair breakdown, as reported?
Frame A's priced lines are excavation at $2.50 to $15 per cubic yard, fill dirt at $5 to $25 and topsoil at $10 to $50 per cubic yard, the cover lines, and land clearing at $1,200 to $8,000 per acre as the access line. Frame B prints no per-unit breakdown lines.
What do the cover lines print at, as reported?
Frame A prints a slope erosion control grid at $1 to $2 per square foot and sod at $1 to $2 per square foot. Frame B prints no cover line; its $1 to $2 per square foot figure is an average across the whole finished project, a different counting that is never blended with the cover lines.
What does the excavation line print at, as reported?
Frame A prints excavation at $2.50 to $15 per cubic yard, beside fill dirt at $5 to $25 and topsoil at $10 to $50. Frame B prints no excavation figure; the reading there sits inside the project totals, an average at $2,159 and most at $1,097 to $3,487.
What does the access line print at, as reported?
Frame A prints land clearing at $1,200 to $8,000 per acre, the reading that stands as the access line here. Frame B prints no access line; its readings run from $700 to $5,000, as project totals alone.
Can the breakdown lines be added into one total?
No. The line figures sit inside their own frames, the project totals sit as their own readings, and no combined total is printed here. No Frame B line is summed into a Frame A total, on a page pricing residential slope repair alone.
