Retaining Wall Cost Calculator for San Diego
Pick the wall type, its length and height, where the property is and what sits above the wall. The calculator multiplies the face area by a typical San Diego-area range and lists engineering, a soils report and permit fees as their own lines.
Estimate your retaining wall
Wall budget
$6,400 to $22,400
Segmental (interlocking) block, about 160 sq ft of face. Installed wall. Short gravity walls on open, level sites land near the low end; walls with geogrid, a driveway or slope above, or hand-carry access land near the top.
Per-foot check: segmental walls about 3 to 4 ft tall typically run roughly $140 to $500 per linear foot before engineering and permits, about $5,600 to $20,000 for 40 ft.
Kept separate
- City of San Diego permit fees, one wall of 40 ft: $2,800 to $4,650 (City of San Diego DSD fee schedule)
A permit line appears because it is over 3 ft from the top of the footing.
All lines together
$9,200 to $27,050
Typical San Diego-area budgeting ranges, not a quote. Rock in the excavation, drainage outlets, access, survey, grading or right-of-way permits and landscape restoration are found at the site visit.
How the calculator works
This retaining wall cost calculator from Batterline San Diego Retaining Walls does one piece of arithmetic: the wall's face area (length times height) times a typical San Diego-area price per square foot for the wall type you pick. Nothing else is multiplied. There is no size discount and no regional factor, so two walls with the same face area and type get the same range.
The ranges are wide because the work behind them is. A short segmental block wall on a flat, open yard sits near the bottom; a wall with geogrid, a driveway or a slope above it, or no machine access sits near the top. Poured concrete is split in two because a plain 3 ft wall and an engineered, waterproofed hillside cantilever are different jobs; the calculator moves a taller, engineered or loaded poured wall to the engineered range on its own. Stone, boulder and timber walls have no published local range, so the calculator lists what sets their price instead of guessing a number.
Permit fees come from the agencies' own schedules: the City of San Diego Development Services Department fee schedule (Information Bulletin 501) for one wall, in 50 ft steps, and the County of San Diego Planning and Development Services fee schedule (PDS 613) for unincorporated areas, from an over-the-counter review to full plan check. A permit line appears when the wall is over 3 ft from the top of the footing, holds a driveway or a slope above it, or is engineered, because in both the City and the County height alone doesn't decide it. The retaining wall permit guide explains those triggers, and other cities in the county set their own fees, confirmed for the address.
Engineering and a soils report are lines you switch on. Whether a wall needs them depends on its height, the soil, the load above and the mapped geology, which the guide to wall engineering walks through. The retaining wall cost guide has the same ranges with what each one covers and illustrative budgets.
What the calculator can't see: rock in the excavation, how far water has to be carried to an outlet, the condition of an old wall that has to come out, survey, grading or right-of-way permits, and the planting and irrigation that get disturbed. Those come out of the first visit, which measures the wall, the load above it, the drainage and the access, and they are why the result is a budget rather than a price.

The calculator gives a budget. A site visit measures the wall, the load above it and the access, and the estimate names the permit path, the drainage and what is excluded.
