Land Surveyor in El Sobrante

El Sobrante is unincorporated — permits, planning, and subdivision applications run through Contra Costa County rather than a city hall, which changes timelines and requirements compared with neighboring Richmond or Pinole. The valley's semi-rural character means larger lots, long driveways, horse properties, and creek-adjacent parcels along San Pablo Dam Road, with hillside edges rising toward the San Pablo Reservoir watershed. Older parcels sometimes carry well, septic, and access easements that deserve resolution before a sale or building project, and fence lines on large lots have often drifted from deed lines over decades.

We provide boundary surveys and parcel maps built on thorough county records research, laser-scanned topographic surveys for hillside and creek-setback design, and site plans prepared for the county's review process.
