Parcel Maps in Emeryville, CA

Emeryville's land-division work looks different from its neighbors'. In a small, densely redeveloped city built largely on former industrial ground, the common problem is not splitting one lot into two — it is cleaning up what a century of industrial ownership left behind. Old plants assembled land piecemeal: multiple underlying lots, remnant slivers from railroad spurs and vacated streets, and boundaries that no longer match how the site is used. Before a mixed-use or live-work infill project can proceed, those underlying parcels usually need to be merged, adjusted, or re-divided so the building sits on a single legal lot. The Subdivision Map Act provides the tools — parcel maps for divisions of four or fewer lots, lot line adjustments to shift boundaries between existing parcels, and mergers to consolidate them — and choosing the right instrument up front saves months.

The chain of title on former industrial land demands real research. We trace the record back through the assemblage, resolve the boundary from recorded maps and found monuments, and then prepare the tentative map or adjustment exhibits the City requires. Approved maps and adjustment documents record with the Alameda County Recorder; a merger or adjustment does not exist legally until that recordation happens. Where our retracement encounters monuments that construction will destroy — common on redevelopment sites — Business and Professions Code §8771 requires they be preserved by record before the ground is disturbed.

Emeryville's compact, congested parcels are ideal scanning territory. Our Trimble terrestrial laser scanner captures an entire site — buildings, pavement, utilities at grade, and the surrounding street frontage — in one mobilization, producing a point cloud that supports the parcel map, the as-built survey, and the design team's site model from a single dataset. On bay-mudflat fill in a mapped liquefaction zone, that existing-conditions record also feeds the geotechnical work most projects here require.
