Land Surveyor in Antioch
Land surveying in Antioch, California. Boundary surveys for the historic riverfront downtown and newer subdivisions, topographic mapping, ALTA surveys, and Delta-adjacent property documentation.
Surveying & 3D Scanning in Antioch
Antioch spans a century and a half of development — a riverfront downtown platted in the 1850s, mid-century neighborhoods, and the broad newer subdivisions that made it one of East County's largest cities. Downtown boundary work means retracing some of the county's oldest maps; Delta-adjacent parcels raise waterfront, levee, and flood-elevation questions; and continuing growth toward Sand Creek keeps boundary, topo, and staking work active.
We survey across all of Antioch's eras, and provide 3D laser scanning for the downtown's historic commercial buildings as revitalization brings renovation and adaptive-reuse projects that need accurate as-built documentation.
