ALTA/NSPS Surveys in Antioch, CA

Antioch is a real commercial market, and its ALTA/NSPS work spans the full range: historic buildings in the riverfront downtown, retail centers along the major corridors, industrial and logistics property along the San Joaquin River and the Delta shoreline, and land positioned around the BART station. Every one of these transactions runs through the same gate — a lender and title insurer requiring an ALTA/NSPS Land Title Survey to the 2021 Minimum Standard Detail Requirements, with the boundary resolved, every title-commitment exception plotted, improvements located, and encroachments disclosed. As one of the county's oldest cities, Antioch also has one of its longer paper trails; downtown parcels can carry descriptions and easements dating to the nineteenth century, all of which we run to ground through the Contra Costa County Recorder and County Surveyor records in Martinez.

The riverfront deserves particular care. Antioch's industrial shoreline developed around rail service and river commerce, and parcels along the San Joaquin routinely carry old rail corridor instruments, spur-track easements, and utility rights-of-way that predate the current parcel fabric — the classic ingredients of a survey exception a title officer cannot underwrite around without a current ALTA. Portions of the Delta shoreline and lower-lying riverfront ground also fall within state-mapped liquefaction zones under the Seismic Hazards Mapping Act, and flood-zone classification is available as an optional Table A item. On retail centers, the practical issues are different but just as real: reciprocal easement agreements, shared access and parking rights, and pad-parcel boundaries that must be shown exactly.

Our Trimble terrestrial laser scanner captures a full center or industrial site in one mobilization — buildings, parking fields, docks, rail spurs, and adjoiner improvements as millions of survey-grade points. Parking counts, building footprints, and building heights for Table A come out of the cloud rather than out of return trips, and the cloud remains reusable after closing for as-built, tenant-improvement, and expansion planning.
