Land Surveyor in East Bay
The East Bay spans two counties and an extraordinary range of terrain — from bay-front flatlands to the rugged East Bay Hills, across the Hayward Fault and into the suburban valleys of Contra Costa County. We survey properties throughout Oakland, Berkeley, Walnut Creek, Fremont, and dozens of communities in between.
Terrain & Geography
The East Bay's geography divides naturally into distinct zones. The bay-front flatlands of Oakland, Alameda, Berkeley, and Richmond sit on a mix of alluvial deposits and bay mud, with some areas built on fill. These flat parcels present straightforward topography but can involve complex subsurface conditions relevant to construction surveys.
The East Bay Hills rise sharply to elevations of 1,500 feet and more, running from Richmond south through the Oakland-Berkeley Hills to Hayward. Properties in these hills feature steep grades, dense vegetation, and narrow winding roads that complicate access for survey crews and equipment.
East of the hills, the Diablo Valley — including Walnut Creek, Concord, and Pleasant Hill — offers more moderate terrain, though the flanks of Mount Diablo (3,849 feet) present their own challenges. Further south, the Tri-City area (Fremont, Newark, Union City) sits on the relatively flat Fremont Plain with a mix of older suburban lots and newer planned developments.
Local Regulations & Permitting
East Bay surveyors must navigate a dual-county system. Alameda County and Contra Costa County each maintain separate recorder's offices, assessor's offices, and public works departments. Records of Survey and Corner Records must be filed with the appropriate county, and research often requires visiting both counties' records.
Oakland's planning department enforces complex zoning requirements, including hillside development standards that dictate setbacks, lot coverage, and grading limits on slopes. Berkeley's similarly rigorous Zoning Ordinance includes landmark and environmental review requirements that can affect survey scope for development projects.
Properties near the Hayward Fault fall under the Alquist-Priolo Earthquake Fault Zoning Act, which requires geologic investigations — and often supplementary survey work — before new construction. The fault trace runs directly through portions of Hayward, Fremont, Oakland, Berkeley, Richmond, and El Cerrito.
Contra Costa County communities like Walnut Creek and Danville have their own design review processes and hillside development standards that integrate with survey requirements for new construction and remodels.
Common Property Types
Oakland Hills homes: Properties in the Oakland and Berkeley Hills are typically on irregular, steep lots with custom-built homes. Many date from the early-to-mid 20th century with original surveys of varying quality. The 1991 Oakland Hills firestorm destroyed over 3,000 homes, and the subsequent rebuilds generated extensive modern survey records for the affected area.
Bay-front industrial conversions: West Oakland, Emeryville, and Richmond are experiencing conversions of industrial parcels to residential and mixed-use developments. These projects require ALTA/NSPS surveys, environmental boundary delineation, and often easement research for historic railroad and utility corridors.
Suburban subdivisions: The Tri-Valley (Dublin, Pleasanton, Livermore) and Tri-City areas contain large-scale tract developments where boundary surveys typically reference recorded subdivision maps. These are generally straightforward but require verification of monument preservation.
Agricultural and rural parcels: Eastern Contra Costa County (Brentwood, Discovery Bay) still has working agricultural land with large parcels, irrigation easements, and older metes-and-bounds descriptions that require careful boundary analysis.
Surveying Challenges in East Bay
Post-fire rebuild surveys: The 1991 Oakland Hills fire and subsequent wildfires have created areas where original monuments were destroyed by heat and debris flows. Surveyors must reconstruct boundary evidence from pre-fire records, neighboring surveys, and any surviving physical evidence.
Hayward Fault displacement: The Hayward Fault creeps at approximately 4-5mm per year, and properties straddling or near the fault may show measurable displacement over decades. Survey monuments set near the fault require periodic verification, and boundary surveys must account for potential ground movement.
Dense hillside vegetation: East Bay Hills properties are often heavily wooded with eucalyptus, oak, and bay laurel. Clearing sight lines and establishing GPS connectivity beneath dense canopy adds time and complexity to surveys in these areas.
Bay mud and fill: Survey monuments set in bay mud or fill areas can shift over time due to settlement and consolidation. Control networks in these areas require frequent verification against stable benchmarks.

Frequently Asked Questions
Do I need a survey after the Oakland Hills fire area rebuilds?
If your property was affected by the 1991 Oakland Hills firestorm or subsequent fires, original survey monuments may have been destroyed. A new boundary survey can re-establish your property lines using pre-fire records, neighboring surveys, and any surviving evidence. This is especially important before construction or if you have questions about fence or structure placement.
My property is near the Hayward Fault. Does that affect my survey?
Properties near the Hayward Fault may fall within an Alquist-Priolo Earthquake Fault Zone, which can require additional investigations before new construction. The fault also creeps slowly, which can affect monument positions over time. Our surveys account for these conditions and reference current USGS fault trace mapping.
Which county handles my survey records — Alameda or Contra Costa?
It depends on your property's location. The county line runs roughly along the ridge of the East Bay Hills. Oakland, Berkeley, Fremont, and Hayward are in Alameda County. Walnut Creek, Concord, Lafayette, and Richmond are in Contra Costa County. We file Records of Survey and Corner Records with the appropriate county recorder's office.
