Topographic Surveys in Berkeley, CA

Berkeley is one of the strictest permitting environments in the East Bay, and the city routinely requires surveyor-stamped site plans before it will process additions, ADUs, and new construction. In the Hillside Overlay district that requirement has teeth: switchback streets, shared driveways, and generations of old retaining walls mean the existing conditions on a Berkeley Hills lot are rarely what the assessor map suggests. Accurate contours determine average slope calculations, height measurements taken from existing grade, and whether a proposed design clears the daylight plane — numbers that can make or break a project at the zoning counter. The Hayward fault crosses the city too (it famously split UC's Memorial Stadium), and parcels near the fault trace draw extra scrutiny on site documentation.

Down in the flats the problems shrink in scale but not in consequence. Berkeley's narrow lots and early-1900s brown-shingle housing stock produce setback questions measured in fractions of a foot, and a topo that also locates building corners, fences, walls, and eaves lets your designer resolve them before plan check does. Our Trimble laser scanner is built for exactly this density of detail: millions of points in one site visit instead of a few hundred pole shots, capturing every wall face, step, driveway grade, and drip line at once. On hillside parcels we filter vegetation from the cloud to deliver a true bare-earth model beneath the mature landscaping, and because the full site lives in the point cloud, a missed shot never means a return trip — we extract it in the office.

Deliverables include 1-foot contours (or tighter), spot elevations, a DTM, and a layered DWG/DXF base map, with recording and records research through the Alameda County Recorder and County Surveyor. Where property-line certainty matters as much as terrain, our boundary + topographic site plan surveys combine both in one instrument setup.
