The lines priced apart: excavation, fill and topsoil, cover, and access lines each stand inside their own frame, never summed.

Orange County, CA · Updated 2026 · Costs shown as ranges — your quote will vary by installer and scope

Reading this guide: every figure below is a range compiled from published 2026 pricing data for Orange County — not a quote. Two published frames, Frame A (the HomeGuide leveling-and-regrade frame) and Frame B (the Angi Los Angeles yard-leveling frame), are named apart and never blended: Frame A counts the work by its printed per-unit lines and carries the erosion-grid line; Frame B counts the finished project by its square-foot average and project totals and carries no per-unit method lines.

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 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.
