Commercial site grading for mountain ground.
Mass cut-and-fill, engineered subgrade for pads and parking lots, and NC E&SC-compliant erosion control — built to your civil plans across Buncombe, Henderson, Transylvania and Haywood, on the real slope your site sits on.
A commercial site grading contractor in Western North Carolina builds the engineered subgrade a building pad, parking lot, or loading apron has to sit on — mass cut-and-fill, structural fill placed in compacted lifts, and stormwater grading to the civil plans and geotechnical spec. The defining difference from residential work is permitting: a commercial site almost always disturbs more than one acre, so an NC E&SC plan (NC GS 113A-57(4) (Sedimentation Pollution Control Act of 1973)) at $119/acre is required, not optional. And the ground is steep — Buncombe’s Evard soils typify a 34.8% slope and Henderson’s ridge Ashe reaches 40.2% — so the fill under your slab has to be keyed and compacted right the first time.
Commercial grading is a tolerance problem, not just a dirt problem
A house pad can carry a little imperfection. A commercial slab, a 200-stall parking field, or a tilt-up footing cannot — settlement under pavement or a slab cracks it. On WNC’s steep, well-drained ridge soils (Evard, Cowee, and Edneyville in Buncombe and Transylvania; Ashe, Porters, and Unaka in Henderson) that overlie weathered saprolite, that means reading where the firm ground is, cutting to a real subgrade, and building structural fill in compacted lifts to the density the geotechnical report calls for — not just shaping dirt until it looks level.
The 1-acre line that residential rarely hits — and commercial almost always does
North Carolina’s Sedimentation Pollution Control Act (NC GS 113A-57(4) (Sedimentation Pollution Control Act of 1973)) draws a hard line at one acre of disturbance. The median WNC residential lot stays under it — only 30% of Buncombe parcels and 41% of Henderson parcels are even an acre — but a commercial pad with its parking, drives, and detention almost always clears it. So on commercial work an approved Erosion & Sedimentation Control plan, filed 30 or more days prior to initiating the activity at $119 per acre (2025-07-01), is part of nearly every job. We sort jurisdiction first — state DEMLR (Asheville Regional Office) vs. a delegated county program — and keep the controls maintained through construction. Detail lives in our NC land grading permits guide and the per-county Buncombe and Henderson permit pages.
Built to the civil plans, sequenced to the GC’s schedule
Most commercial work runs off a stamped civil and grading plan. We build to the staked elevations, sequence erosion control and mass grading around the concrete, utility, and paving crews, proof-roll and test compaction with your engineer, and keep the site drained and inspection-ready. One crew across site preparation, land clearing, and drainage means the subgrade, stormwater, and finished grades actually match the drawings.
What drives your commercial number
Three things move the price more than anything: how steep the site is, how much rock is in the cut, and how much structural fill the pad and lot need. A near-level infill site on Tate or Hayesville bottomland is predictable; a benched pad on a 40.2% Ashe ridge with saprolite means retaining, rock handling, and bigger fill volume. We price off your plans and a site walk — not an invented per-acre table, which is always wrong for mountain ground.
Buncombe’s well-drained Evard ridge soil — the structural fill on top has to be keyed and compacted to spec.
The slope your commercial site is actually on, by county.
Dominant USDA-NRCS soil series and slope for each county we serve — the real ground behind every mass-grading and structural-fill quote. Slope range is the county envelope; “typical” is the most-common grade for that dominant series.
| County | Survey | Dominant series | Typical slope | Slope range | Commercial implication |
|---|---|---|---|---|---|
| Buncombe | NC021 | Clifton | 16% | 2–95% | Level subgrade + engineered structural fill |
| Henderson | NC089 | Ashe | 40.2% | 0–95% | Benched mass cut-and-fill + structural fill |
| Transylvania | NC175 | Unaka | 37.6% | 2–95% | Benched mass cut-and-fill + structural fill |
| Haywood | NC606 | Wayah | 27.8% | 2–95% | Benched mass cut-and-fill + structural fill |
Across all four counties, the dominant ground runs from 27.8% (Haywood’s Wayah) to 40.2% (Henderson’s Ashe) typical slope — commercial pads here are benched, not just leveled.
Priced off your plans, not a per-acre table.
Commercial grading varies too much with slope, rock, and structural-fill volume to publish a flat rate. Here’s how the three commercial site types break down — exact pricing comes from a free on-site estimate against your civil drawings.
Tate, Hayesville, or bottomland soils under ~10% slope. Strip, cut to subgrade, place and compact structural fill, drain. Still an E&SC plan if it tops one acre, but the most predictable to price.
Evard, Edneyville, Cowee ridges at 15–30%. Mass cut-and-fill to a benched pad and parking field, built in compacted lifts with E&SC and stormwater grading. The most common WNC commercial site.
Ashe, Porters, Unaka at 40.2%+ with saprolite or outcrop. May need a hammer, retaining, import/export of fill, and a tight-access plan. We flag rock against your geotech on the site walk.

From civil plans to a compacted, inspection-ready site.
Read the plans & walk it
We review the civil, grading, and geotech reports, then walk the site to read slope, soil, rock, and access.
Permit & erosion control
E&SC plan jurisdiction confirmed, controls installed first — silt fence, construction entrance, basins — and maintained throughout.
Mass grade & structural fill
Cut to subgrade, build fill in compacted lifts keyed into firm ground, proof-roll and test with your engineer.
Fine grade & hand off
Shape to final elevations, stormwater verified, compaction documented, site left ready for paving, concrete, or footings.
