Topographic Surveys in Pleasant Hill, CA

Pleasant Hill is one of the most active ADU and infill markets we serve, and topography is where many of those projects quietly succeed or fail. The city's postwar ranch lots look flat at a glance, but an inch or two of fall across a backyard determines whether an ADU can drain to the street, whether a new pad needs import or export, and where downspouts and area drains have to go. Our Trimble terrestrial laser scanner captures the entire lot — ground, driveway, fences, existing structures, and overhead utility drops — as millions of survey-grade points in one visit. From that point cloud we build a digital terrain model, 1-foot contours (with tighter intervals where drainage design demands it), spot elevations, and a DWG/DXF base map that drops straight into your designer's software.

Creek corridors and flood channels thread through Pleasant Hill, and parcels backing onto them carry extra mapping needs: top-of-bank location, channel cross-sections, and enough terrain detail to support setback and drainage review. Scanning is well suited to these edges because we can capture steep, brushy banks safely from a distance and then filter vegetation in the office to expose the true ground surface — something a handful of conventional shots through the underbrush cannot honestly represent. We have also mapped commercial parcels around the rebuilt downtown core and the DVC college area, where dense site improvements benefit from the completeness of a point cloud.

Every Pleasant Hill topographic survey includes record research at the Contra Costa County Recorder and County Surveyor in Martinez, so our mapping is tied to recorded maps and reliable benchmarks rather than assumed datums. If your project also needs certainty about the property lines — a frequent question when an ADU is pushed toward a rear setback — ask us about combining the topo with boundary resolution in a single scope.
