Designing and building mountain homes across Western North Carolina requires detailed three-dimensional ground terrain data. Flat site plans cannot capture steep rock ledges, natural ravines, and 40-degree grades. Our surveying teams utilize drone LiDAR, robotic total stations, and 3D digital terrain modeling to generate precise 1-foot contour maps that satisfy municipal steep-slope development ordinances and empower architects and engineers.
Dense Appalachian rhododendron and mountain laurel canopies blind standard satellite and photogrammetric cameras. We fly specialized aerial LiDAR systems that emit hundreds of thousands of laser pulses per second, penetrating forest canopies to map the true bare-earth ground surface beneath.
Using AutoCAD Civil 3D, we generate detailed digital elevation models (DEMs) featuring 1-foot and 2-foot contour intervals. These precise topographic baselines reveal natural drainage swales, rock outcroppings, slope breaks, and optimal building envelope footprints.
Counties across Western NC (including Buncombe, Watauga, and Haywood) enforce strict steep-slope development ordinances for parcels exceeding 15 to 25 percent average slope. We calculate certified average slope percentages and delineate buildable footprint envelopes to secure county zoning approval.
Fine mountain home architecture incorporates natural site beauty. In addition to ground contours, we survey the exact trunk location, ground elevation, and diameter of mature specimen hardwood trees, rock formations, and mountain springs to preserve them in final designs.
A steep-slope certificate is a document sealed by a licensed surveyor or engineer calculating the average slope of a parcel, identifying hazard areas, and certifying whether proposed construction complies with local mountain protection ordinances.
LiDAR emits laser light pulses that pass through small gaps between leaves and branches. While some pulses reflect off the canopy, thousands of pulses reach the ground, allowing software to filter out vegetation and model bare earth accurately.
We deliver certified PDF survey plats alongside digital DWG/DXF AutoCAD Civil 3D drawings with 3D contour polylines, surface tins, and point data for direct import into architectural software.
