Parcel Maps in Pittsburg, CA

Pittsburg's minor-subdivision work splits along its geography. In the newer hillside subdivisions of the southeast hills, we handle lot line adjustments where graded pads, drainage swales, and rear-yard slopes did not land quite where the recorded lines suggest — a common condition in hillside tracts, where the useful part of a lot is the pad and the recorded boundary runs somewhere up or down the slope. An adjustment under the Subdivision Map Act can align ownership with the improvements, subject to City of Pittsburg approval, and we verify the adjusted lots still meet zoning standards before anything is signed. General hillside prudence applies: we document slopes and drainage carefully so the adjustment does not create maintenance ambiguities between neighbors.

Down along the waterfront, Pittsburg's industrial heritage — steel, chemical plants, and the old downtown grid near the water — has left large parcels now in transition. Reconfiguring them for reuse is parcel map and lot line adjustment territory at industrial scale: assembling or splitting sites, carving out utility corridors, and resolving decades of easements, rail spurs, and legacy descriptions. Our Trimble terrestrial laser scanner is built for these sites; in one mobilization we capture boundary evidence plus a survey-grade record of structures, paving, rail, and grade across acres, producing both the map base and an as-built record a redevelopment team can design against. On low-lying Delta-margin ground, we also check state Seismic Hazards Mapping Act liquefaction zones during feasibility.

Every Pittsburg map follows the same closing path: tentative approval through the city, map check by the Contra Costa County Surveyor, monuments set and perpetuated per Business and Professions Code §8771, and recordation with the County Recorder in Martinez. We begin with a feasibility review so you know the constraints — zoning, easements, access, hazard mapping — before the first application fee is paid.
