Topographic Surveys in Martinez, CA

We produce laser-scanned topographic surveys throughout Martinez, the county seat of Contra Costa County — from hillside neighborhoods above downtown to semi-rural Alhambra Valley acreage.

Topographic Surveys in Martinez: Local Conditions

Martinez terrain rewards a dense topographic survey. The hillside neighborhoods that climb away from the 1800s downtown grid sit on slopes where a grading or drainage plan lives or dies on the accuracy of the contours, and the semi-rural parcels of Alhambra Valley to the south often combine steep oak-studded ground with long driveways, creeks, and scattered outbuildings. On sites like these we deploy a Trimble terrestrial laser scanner instead of a conventional one-point-at-a-time topo. A traditional crew might shoot a few hundred ground shots across a hillside lot; our scanner captures millions of survey-grade points in a single visit, and we filter the vegetation from the point cloud in the office to build a true bare-earth digital terrain model. The result is 1-foot contours, spot elevations, and a DWG/DXF base map your architect or civil engineer can design on with confidence — plus the full point cloud if the design team wants it.

For hillside additions, ADUs, retaining walls, and grading permits, Martinez plan reviewers expect topographic mapping that reflects actual site conditions, and dense scan data means fewer surprises when the excavator arrives. Because Martinez is the county seat, the Contra Costa County Recorder and County Surveyor offices are located right in town, which streamlines our research: we pull recorded maps, benchmarks, and survey records for your parcel as part of every project. When a project also needs the property lines resolved — common on older Martinez lots where fences wandered long ago — we can pair the topo with boundary work as a combined boundary and topographic survey.

Whether you are planning a hillside remodel above downtown, a barn or second unit in Alhambra Valley, or civil improvements on a commercial parcel, we scope each Martinez topographic survey to the permit path you are actually on, so you buy exactly the mapping your project requires.

What's Included

  • Trimble laser scanning: millions of points, one site visit
  • Contours, DTM, and spot elevations at any interval
  • CAD-ready DWG/DXF base maps for architects and engineers
  • No return trips for missed shots — the scan has everything
  • Vegetation-filtered ground models on brushy hillside lots
  • Point cloud deliverable available for design teams

Our Process

1

Scope & Research

We confirm the mapping limits, contour interval, and datum your project requires, and review record maps and benchmarks for the site.

2

Field Scanning

We capture the site with a Trimble terrestrial laser scanner plus GNSS/total-station control, recording millions of survey-grade points in a single visit — terrain, structures, walls, trees, and utility surface features.

3

Point Cloud Processing

Scans are registered onto project control, vegetation and noise are filtered, and a ground surface is extracted to build the digital terrain model.

4

Base Map Delivery

You receive a layered DWG/DXF topographic base map — contours, spot grades, features, and boundary if requested — with the point cloud available on request.

Topographic Surveys in Martinez: FAQ

Almost always, yes. On sloped Martinez lots the City typically requires grading and drainage plans prepared on accurate topographic mapping, and your architect needs real contours and spot elevations to set finish floors and retaining walls. Our laser-scanned topos give the design team 1-foot contours and a DTM built from millions of points rather than a sparse grid of shots.
Yes. Alhambra Valley parcels often mix steep slopes, mature oaks, creeks, and multiple structures. Terrestrial laser scanning lets us capture that complexity in one mobilization, then filter vegetation in the office to produce a clean bare-earth terrain model — far more complete than a conventional topo on ground like this.
A signed topographic map with contours and spot elevations, a DWG/DXF CAD base map layered for design use, and the classified point cloud on request. We also research recorded maps and benchmarks at the Contra Costa County Recorder and County Surveyor, conveniently located here in Martinez.
