Los Angeles County · Land Surveying
Pomona spans everything from Victorian-era neighborhoods platted in the citrus boom to hillside homes near Ganesha Park and modern warehouse corridors — one of the widest ranges of survey conditions of any city in the county.
From a single lot to a full site, describe the project and we will match the survey to it. Call (213) 787-3342 to talk it through.
Few LA County cities cover Pomona's spread of property types. Its historic districts hold homes on subdivisions recorded in the 1880s and 1890s, whose legal descriptions and monuments predate modern standards by decades. Its central neighborhoods carry the compact grid typical of the region. Its northern edges climb into hillside terrain, and its southern and eastern corridors host industrial and logistics buildings served by rail and the freeway network.
Each of those settings generates different work: painstaking boundary retracement in the oldest tracts, setback and ADU surveys on the residential grid, topographic mapping on the slopes, and ALTA/NSPS and as-built surveys for the industrial stock. We scope each Pomona request against its actual neighborhood rather than treating the city as one uniform market.
Depending on the neighborhood, Pomona work usually draws on six services:
Boundary work in Pomona's oldest neighborhoods is genuinely archival. Descriptions can reference maps more than a century old, and generations of street widening, alley vacations, and re-subdivision layer onto the original geometry. Retracement means assembling that record chain and reconciling it with what remains in the ground; where corners must be re-established, we file the corner records or records of survey the situation requires with Los Angeles County.
At the other end of the spectrum, Pomona's commercial and industrial transactions run on modern documentation: ALTA/NSPS surveys tied to the title commitment for purchases and refinancing, topographic and as-built mapping for site redevelopment, and construction staking when projects break ground. Institutional and campus-adjacent properties add their own layers of easements and utilities worth mapping carefully. Specific development requirements should be confirmed with the city's planning and building departments.
Because record chains here can be long, documents help more than usual:
We trace the record chain for the parcel, confirm scope and deliverables against your project, then field-measure and deliver the survey, staking, or exhibits — with any required corner documentation filed. The steps are laid out at how it works.
Across Pomona’s neighborhoods, requests often involve:

Yes. Those subdivisions were surveyed and monumented when recorded, and retracement works from that record plus every reliable survey since. It takes more research than a modern tract, but the boundary is recoverable — that is the core craft of boundary surveying.
We translate the approved design into marked points on the ground — building corners, gridlines, curb and utility alignments, and grade stakes — at the stages your contractor needs them, so the built work matches the plans.
Dividing land involves both city approval and recorded survey mapping, and California law sets who may prepare those maps. The exact path depends on the proposal, so confirm process requirements with the city's planning department; we prepare the exhibits, legal descriptions, and supporting survey work an application needs.
Often, yes. An ALTA or boundary survey for the transaction can be scoped so the same fieldwork supports a topographic base map for design, which is cheaper than mobilizing twice. Tell us both goals up front and we will structure the scope that way.
Not always. Flat-lot projects may only need boundary and setback work. Topo earns its cost when grading, drainage, or hillside conditions affect the design — we will tell you honestly which situation yours is.
Survey scope and deliverables depend on title records, site conditions, and what your project requires. Call (213) 787-3342 to discuss the property and the survey you need.
