Parcel Maps in Benicia, CA

The Benicia Industrial Park — the former Benicia Arsenal, now a major warehouse and manufacturing district on the Carquinez Strait — is where most of our Benicia mapping work concentrates. Industrial users outgrow their parcels, consolidate yards, or carve a surplus corner for sale, and each move is a Subdivision Map Act transaction: a lot line adjustment, a merger, or a parcel map division of four or fewer lots. Arsenal-era history complicates the record — parcels descend from federal military land through successive conveyances, and surviving arsenal-era stone and masonry buildings targeted for adaptive reuse sit on lots whose lines were drawn around uses that no longer exist. We resolve that record, reconfigure the parcels to match the actual redevelopment plan, and perpetuate affected monuments under Business & Professions Code §8771. Along the strait frontage, we flag mapped liquefaction zones under the Seismic Hazards Mapping Act where they bear on conditions of approval.

Downtown is a different world. Benicia's grid was platted in the 1840s — the city briefly served as state capital in 1853–54 — making it among the oldest plats in Northern California. A lot line adjustment between downtown parcels means reconciling 180-year-old plat geometry with modern occupation, and the record and the fences rarely agree. We treat these as boundary-resolution projects first and mapping projects second, because an adjustment built on an unresolved boundary simply records a new dispute.

One practical note: although Benicia sits on the strait a few minutes from Contra Costa County, it is in Solano County, so every map is examined by the Solano County Surveyor and recorded with the Solano County Recorder in Fairfield. We manage that Fairfield plan-check and recordation cycle routinely. Our Trimble terrestrial laser scanner lets us capture boundary evidence and a survey-grade topographic base — critical inside working industrial yards, where scanning from the perimeter keeps our crew clear of truck traffic — in a single mobilization.
