Land grading in Cashiers.

On the plateau, a flat lot is built — not found

Cashiers sits high on the southern Jackson County plateau, around 3,500 feet, at the crossroads where US 64 meets NC 107. It’s granite-dome country — Whiteside Mountain stands just east of the crossroads, the Chattooga River heads up off the plateau’s southern edge, and the West Fork Tuckasegee feeds Lake Glenville to the north. That terrain sets the whole land-grading story apart from the river-valley towns down the mountain: there is very little naturally flat ground, so the level pad your house, shop or yard needs is something we build out of the slope, not something the lot already has.

Steep, well-drained upland soils are what the plateau stands on. The USDA survey (NC099) describes a series named for the town itself — the Cashiers series, a Humic Dystrudepts mapped on these high shoulders at a typical 34.5% slope. Around it the dominant ground is Chandler (a Typic Dystrudepts, 34.5%) and Wayah (37.7%), with the bouldery Cullasaja (33.5%) and steeper Chestnut and Plott (44.7%) on the higher shoulders. At those grades a land grade isn’t strip-and-level — it’s a true cut-and-fill bench.

The bench: cut the high side, compact the low side

Benching a pad on the steep Cashiers, Chandler, Wayah and Cullasaja shoulders is real cut-and-fill work. We cut into the high side, place that spoil back as compacted fill in lifts on the low side, key the fill into firm benched ground so it locks into the hillside instead of riding on top of it, and hold the cut and fill faces with retaining and erosion control. The pad is then graded to shed water away from the foundation. Fill that’s simply tipped over the downhill edge — not keyed, not compacted in lifts — is what settles under a slab and slides in a hard mountain storm, which is exactly what the bench method prevents.

Balancing the dirt — and the Cullasaja rock that throws it off

The question that prices a Cashiers land grade is whether the cut balances against the fill on site. On gentle ground a grader usually moves the high side into the low side and nothing leaves; on these 34.5–37.7% shoulders that balance has to be designed, because over-cutting for a big flat makes more spoil than the pad can absorb — and then dirt gets trucked down narrow plateau roads. The bouldery Cullasaja is the wild card: a Typic Humudepts full of cobbles and stone, so part of what you cut is rock that can’t be compacted back as structural fill and has to be hauled or buried. We size the pad and the cut to keep the balance on site wherever the lot allows. See site prep in Cashiers for the full scope.

The gentle exception — and the 1-acre line

Not every Cashiers lot is a bench. Where one catches a toe-slope Saunook cove or a Braddock terrace bench — both well drained and far gentler at 12.2–15.2% — the pad is mostly leveling and compaction, and a careful site walk is what tells us which kind of ground your specific lot is on. Either way, because Cashiers parcels skew large — a 1.16-acre median with 56.1% at or above one acre and 10.2% at five or more — many grades cross North Carolina’s one-acre disturbance trigger (NC GS 113A-57(4) (Sedimentation Pollution Control Act of 1973)). Above it you need an approved E&SC plan filed 30 or more days prior to initiating the activity at $119/acre, and on this steep Chattooga / Lake Glenville headwater ground even a smaller disturbance needs real sediment control. We confirm whether the NC DEMLR Asheville Regional Office or a delegated local program has jurisdiction before any dirt moves.
