Monument Preservation in Emeryville, CA

Few East Bay cities churn their ground like Emeryville. Former industrial parcels along the waterfront and rail corridor have been remade into live-work lofts, labs, and mixed-use infill, and each project brings demolition, mass grading, and deep utility trenching — all activities that Business & Professions Code §8771 addresses directly. Before construction disturbs a survey monument, a licensed surveyor must reference it and file a Corner Record with the Alameda County Surveyor; after construction, the monument must be reset and a closing Corner Record filed. In a small, compact city where parcels have been assembled, split, and re-subdivided through generations of industrial use, surviving monuments are scarce and disproportionately valuable. Destroying one without preservation converts a modest referencing task into a future retracement across messy industrial-era records.

We serve developers, utility districts, and contractors working in Emeryville with corridor and site-perimeter monument preservation: records research through decades of industrial parcel history, field search, pre-construction referencing and Alameda County filings, and post-construction resets tied to our control network. Utility work here has an added complication — bay-mudflat fill means trench alignments and pavements settle, so a monument’s relationship to surrounding improvements can drift. Documenting surface conditions around each monument before construction protects everyone when questions arise later.

That documentation is where our Trimble terrestrial laser scanner changes the economics. In the same mobilization that references the monuments, we scan the work corridor — monuments, pavement, rails, structures, and utilities at the surface — into a millimeter-grade point cloud. The project gets defensible monument records plus reusable pre-construction scanning data for design and claims, with no second trip.
