Los Angeles County · Land Surveying
San Marino was founded in 1913 as a deliberately residential city of expansive properties, wide streets, and kept parkways — and it has stayed that way. Surveying here means long frontages, generous setbacks, and projects that move through careful review.
Estate frontages and garden projects reward early measurement — share the plans and we will scope from them. Call (213) 787-3342 to talk it through.
The city's founders — the Huntington, Wilson, and Patton ranch interests — laid out San Marino as a purely residential community, and the Huntington's former ranch grounds remain its most famous landmark. The residential fabric they created still governs the work: large parcels, deep setbacks, mature landscaping, and a city that reviews changes closely.
Big lots change the arithmetic of a survey rather than its nature. Frontages run long and often curve, side lines disappear into hedges and gardens, and improvements — walls, pools, tennis courts, guest structures — accumulate across decades of careful ownership. When an estate changes hands or a major landscape project begins, owners want the full measured picture, not a guess scaled off the assessor sheet.
Boundary work on estate lots leans on the city's early subdivision maps and the surveys recorded since. The records are generally good; the field evidence hides — corners land inside hedges, under garden walls, or beneath decades of planting. We search carefully, retrace from what survives, and set durable reference marks positioned to serve the property for the long term.
The bigger the project, the more the survey carries. Full garden and hardscape renovations start from topographic mapping — grades, drainage, trees, existing improvements — with the boundary overlaid so designs respect both the terrain and the setbacks. Additions and accessory structures need measured setback exhibits for plan review. Requirements vary by project; confirm specifics with the city, and we will build the base those reviews rest on.
Six services cover most San Marino requests — lines and corners first, terrain and documentation as the project demands:
The estate projects that bring San Marino owners to a surveyor include:
Estate scopes benefit from context — any of these helps:
We assemble the early subdivision record and recent surveys, agree the scope with you, then field-measure with the care the property deserves. The sequence is on our how it works page.
From the recorded geometry — curving frontages are defined by arcs in the subdivision record, and we compute and set points along the true curve at useful intervals. Contractors get stakes they can build gates, hedges, or walls to, and the curve lands where the record puts it rather than where the old planting suggests.
Everything the design will react to: boundary, grades, drainage, trees worth keeping, and the existing improvements. A single topographic survey with the boundary resolved gives the landscape architect a complete base, and it prevents the classic estate problem — a beautiful design drawn to lines that turn out to be somewhere else.
Set corners serve more than fences — they anchor every future project, sale, and neighbor conversation. On large parcels where lines run through planting, durable reference monuments mean the next designer or the next owner starts from evidence instead of a fresh search. Many estate owners have them set once and benefit for decades.
Measure first, then decide. We locate the wall and the record line precisely; if the old wall wanders, you and your neighbor can choose between rebuilding true to the line or documenting the existing position by agreement. Either path is fine — what fails is rebuilding blind and discovering the error at the next sale.
Yes. San Marino's founding-era subdivisions reserved parkway and utility rights that still appear in title reports, and we plot the recorded instrument against your improvements so you can see exactly what it touches. Most turn out to be benign; knowing precisely where they fall is what lets you plan gates and plantings with confidence.
