Parcel Maps in Richmond, CA

Richmond's parcel fabric tells its industrial history. The waterfront and the large flat redevelopment areas carry assemblages built up through a century of shipyard, rail, and plant ownership — dozens of underlying lots, remnant slivers from spur tracks and vacated rights-of-way, and record boundaries that stopped matching site use long ago. Before these sites can be financed or entitled for reuse, the legal parcels usually need consolidation or reconfiguration, and the Subdivision Map Act supplies the tools: mergers to consolidate commonly owned lots, lot line adjustments to reshape boundaries between existing parcels, and parcel maps for divisions of four or fewer new lots. Choosing the right instrument — and sequencing it correctly against the title work — is most of the battle on a redevelopment parcel, and we do that analysis before any application is filed.

The residential side of Richmond raises different questions. The WWII-era wartime housing tracts were platted quickly and densely, and their small lots leave little room for division, though lot line adjustments regularly cure garage and fence encroachments there. In the Point Richmond hills, a handful of larger sloped lots can support conventional splits, with feasibility turning on access grades and buildable area. Everywhere in the city, approved maps, mergers, and adjustments record with the Contra Costa County Recorder — nothing is legally effective until recordation. Where redevelopment construction threatens existing survey monuments, Business and Professions Code §8771 requires they be preserved by record first, a step we build into every project on former industrial ground.

Large sites are where our Trimble terrestrial laser scanner changes the economics. One mobilization sweeps acres of pavement, rail remnants, structures, and shoreline edge into a survey-grade point cloud — the existing-conditions base for the map, the as-built survey, and the civil design model in a single dataset, with shoreline liquefaction-zone grades captured for the geotechnical team at no extra visit.
