Buncombe is the county with two erosion programs, and the line between them runs through neighborhoods. Outside the Asheville city limits, the county’s own Erosion Control Division reviews the plan. Inside, the city does. The yard is in Asheville, so every one of the 13 communities below is under 30 minutes for a tracked carrier on a lowboy.
Who reviews an erosion plan in Buncombe County?
The county, unless the parcel is inside Asheville. Buncombe’s Erosion Control Division is a delegated program under the state Sedimentation Pollution Control Act and enforces it in every part of the county except the city and publicly funded work such as DOT and school jobs (Buncombe Erosion Control). The trigger is 1 acre of disturbance. In a subdivision platted under the county’s hillside development standards, the trigger drops to 1/4 acre.
The county’s own fee sheet says $400 per disturbed acre, prorated (county fee schedule). DEQ’s statewide listing of local program fees, dated July 2024, shows Buncombe at $525 per acre and $400 for the 1/4 to 1 acre hillside band (DEQ fee listings). We quote the county number and tell you to confirm it at filing. Either way the fee doubles if the blade cuts before the permit issues.
Inside the city, Asheville’s program starts at 10,000 square feet, which is under a quarter acre (Asheville code). A West Asheville infill lot trips that line with one driveway and a pad. A Leicester pasture edge doesn’t trip the county line until the disturbance is four times bigger. Same county, different desk, different number.
What do the steep slope rules add?
Review before the building permit, on the ground that most of the county is. The county’s Steep Slope and High Elevation Overlay applies above 2,500 feet where natural slopes reach 35 percent, and it puts zoning and site plan review ahead of the permit (county application). Barnardsville, upper Fairview, and the NC 9 climb out of Black Mountain have a lot of ground in that band.
Asheville’s ordinance starts lower and sooner: 2,220 feet elevation and 15 percent grade. It regulates grading, impervious cover, and screening, and it treats retaining walls over 4 feet as their own permit (Asheville steep slope ordinance). Geologists logged 301 landslides in the county by late October 2024, so neither office is loosening those lines. Our steep slope guide walks the application.
Burning, hauling, and the trout strip
A burn pile in Buncombe needs an NC Forest Service permit through the county ranger, and land-clearing debris on more than 5 contiguous acres needs the special permit. Vegetative debris only, 8am to 6pm, Code Green or Yellow air days, 500 feet from an occupied structure (NC Forest Service permits). Demolition of a structure runs through the Asheville-Buncombe Air Quality Agency for asbestos rules before anything is pushed over. Most of our Buncombe jobs skip the fire: forestry mulching leaves the chips as ground cover, and haul-off goes to a C&D landfill on a ticket you can read.
Designated trout waters in the French Broad basin keep a 25 foot undisturbed strip from top of bank. Look the stream up on the DEQ classification schedule before you plan a crossing. Whether a plan is filed or not, a graded slope needs cover within 21 days.
Where Helene still shapes the work
The free programs are over. Buncombe closed its FEMA private property debris program to new applicants on April 15, 2025, at more than 5,000 applications and about 93 percent complete (county debris page). Right-of-way pickup finished the same month at about 1.01 million cubic yards. By October 2025 the county solid waste director was describing a wave of illegal dumping as owners paid unlicensed haulers who vanished with the load (WLOS, October 29, 2025). Dumping more than 500 pounds is a felony under state law.
What that means on a Swannanoa or Black Mountain lot: storm cleanup is a private invoice, the landfill ticket comes back to you, and rebuild pads want a grading contractor and cover in the same week (grading permits in WNC). The Reduce to Rebuild program still waives the county permit fee on a rebuild. It doesn’t haul wood.
Ground and access across the county
Clay saprolite over granite and gneiss, with bedrock that shows up whenever a cut goes deep. The floors along the French Broad and the Swannanoa work like flat land: Arden, South Asheville, and Woodfin take a lowboy and a dump truck without a spotter. The ridges don’t. Alexander, Candler, and Weaverville driveways are where the trailer stops and the carrier walks in.
Pull the parcel on BuncoMap first. The PIN, the city limit, the flood zone, and the slope layer are all on it. That’s the first thing we open on the phone.
