ALTA/NSPS Surveys in San Leandro, CA

San Leandro's commercial identity is its industrial corridor: manufacturing-era buildings along I-880 moving through conversion to logistics, food production, flex, and creative-industrial use. These transactions lean hard on the ALTA/NSPS survey. Mid-century industrial parcels carry rail spur easements, utility corridors, shared truck access, and lease-boundary improvisations that accumulated over decades, and the 2021 Minimum Standard Detail Requirements require each recorded exception to be plotted against the buildings, yards, and fence lines as they exist. Encroachment findings — a fence enclosing part of the neighbor's yard, a dock apron crossing a line, an unrecorded shared drive — are routine on this corridor and routinely change deals.

San Leandro adds a boundary-evidence problem few cities present as vividly: the Hayward fault runs directly through the city, and its aseismic creep visibly offsets curbs and sidewalks over time. Monuments and improvements near the fault trace migrate slowly with the ground, so resolving a boundary means weighing evidence that has physically moved since it was set — a task our resolution notes address explicitly, and one reason B&P Code §8771's monument preservation duty gets careful attention here; see monument preservation. West of I-880, mapped liquefaction zones cover much of the flat, and we can note seismic hazard status alongside Table A item 3 flood zone classification where lenders want it on the face of the survey. Our Trimble terrestrial laser scanner captures a full warehouse property — envelope, docks, yard, fencing, pavement, surface utilities — in one mobilization, with Table A building square footage and parking counts computed from the point cloud, and the same cloud handed to the buyer's design team for the conversion work that usually follows closing.

Record research runs through the Alameda County Recorder, and any Record of Survey our boundary resolution requires under Business and Professions Code §8762 is filed with the Alameda County Surveyor.
