Topographic Surveys in Concord, CA

Concord presents topographic surveying at two very different scales, and our Trimble terrestrial laser scanner handles both. At one end are the city's broad postwar tracts, where homeowners adding second stories, ADUs, and pools need accurate mapping of modest lots — pad elevations, fence lines, driveway grades, and drainage patterns that decide whether a plan sails through review. At the other end sits the former Concord Naval Weapons Station, one of the Bay Area's largest redevelopment sites, along with aging commercial and industrial properties repositioning near the downtown BART station. Large sites like these are exactly where scanning pays off: one instrument setup captures millions of survey-grade points, so we can map acres of pavement, structures, rail spurs, and rough ground in a fraction of the field time a conventional topo would take, then deliver 1-foot contours, a digital terrain model, spot elevations, and a layered DWG/DXF base map — with the full point cloud available to your civil and architectural teams.

Concord also carries a constraint most neighboring cities do not: the Concord fault crosses the city, and portions of it are zoned under the Alquist-Priolo Earthquake Fault Zoning Act. If your parcel falls inside a mapped AP zone, your geologist's fault investigation and the city's review will lean on precise site topography, and we coordinate our mapping so trench locations, setback lines, and surface features all land on one consistent base. Every Concord project also includes record research at the Contra Costa County Recorder and County Surveyor in Martinez, so the topo sits on a defensible basis of bearings and benchmark datum.

For owners repositioning older commercial buildings, we frequently pair site topography with interior-and-exterior as-built scanning, giving the design team the entire property — ground and structure — in a single coordinated model.
