Glendora calls itself the Pride of the Foothills, and its survey work splits along that geography: citrus-era subdivisions and mid-century tracts on the valley floor, and view estates climbing the San Gabriel foothills where slope shapes every project.
Hillside estate or 1910s tract lot, describe the project and we will match the survey to it. Call (213) 787-3342 to talk it through.
Glendora incorporated in 1911 as a citrus town, and groves dominated until residential development took over in the late 1950s. That history left layers: early-1900s subdivisions near the Village, broad mid-century tracts where the orchards once stood, and newer hillside enclaves to the north where lots are larger, streets curve, and grades matter.
Owners on the flats call about the familiar questions — fences, additions, garage conversions, escrow surprises. Foothill owners bring terrain into it: retaining walls, terraced yards, driveways cut across slope, and grading reviews that want measured ground, not estimates. Both start the same way, with the property lines established from the record.
The valley-floor tracts trace to subdivision maps from the citrus decades and the postwar boom. Their geometry is usually sound; the question is what survives in the field after seventy to a hundred years of curb work, driveways, and fence cycles. We retrace from the monuments that remain across each block, and where corners must be re-established, a corner record documents the new monuments with Los Angeles County.
North of the valley floor, the work changes character. Hillside lots carry grade breaks, drainage paths, and walls that were built to lines their builders assumed. Projects there often pair boundary retracement with topographic mapping so the designer, the engineer, and the city all see the same measured surface. Grading requirements vary by project — confirm specifics with the city; our job is the measurements those reviews rely on.
Six services cover most Glendora requests — three about where lines are, two about what the ground does, one for compact-lot conversions:
The projects that bring Glendora owners to the phone usually involve:
Any of these sharpen the scope; none are required to start the conversation:
We assemble the recorded maps and nearby surveys, confirm scope and deliverables with you, then schedule fieldwork. The sequence is described on our how it works page.
It affects the research more than the result. Subdivisions from the citrus decades were legitimately surveyed, but a century of street and utility work has removed much of the original evidence. We retrace from what survives across the neighborhood and reconcile it with the recorded geometry, so the lines we mark reflect the record — not just the oldest fence.
The lines and the grades, together. Wall design depends on where the boundary sits relative to the slope, and wall permits often require elevations and drainage information. Locating the boundary and mapping the topography in one mobilization gives your engineer everything at once.
Yes. We locate the easement as recorded, the driveway as built, and both parcels' lines, then show the relationships on one exhibit. Flag-lot arrangements usually work fine until a sale or a repaving project raises the question — the map answers it with measurements rather than memory.
A drawing showing the located property lines, the existing or proposed structure, and the measured distances between them — the numbers the reviewer wants to verify against the zoning standard. We match the format to what your designer and the city ask for.
Often, yes. Once a project involves grade — cut, fill, walls, or drainage — reviewers want topographic detail that flat-lot additions never need. Whether your specific project triggers that is the city's call; we scope the mapping to the request rather than defaulting to more than you need.
