Local conditions
Survey conditions in Los Angeles County
Los Angeles County sits at the intersection of coastal plains, river floodplains, alluvial fans, and hillside terrain shaped by active fault systems and periodic seismic activity. Before a footing is formed or a graded pad is cut, the design has to land precisely on ground that may slope steeply, carry existing utilities in dense urban corridors, or carry setback requirements enforced by one of the county's many incorporated municipalities and unincorporated planning jurisdictions. A surveying error at this stage costs more to correct than any other mistake on a project. Our Los Angeles County survey crews are dispatched through our regional hub and cover boundary determination, topographic surveys, and construction staking for residential infill, commercial development, public infrastructure, and industrial projects across the county. Every deliverable is checked against the design intent so contractors can build with confidence and permitting agencies receive documentation that matches what is in the field.
Los Angeles County's varied terrain—ranging from coastal lowlands to steep hillside lots subject to California's grading ordinance requirements—means that accurate topographic data capturing existing grades, drainage patterns, and property limits is essential before design or grading work begins. Seasonal conditions, including the wet season typically running from late fall through early spring, can affect site access on hillside parcels and should be factored into survey scheduling.
FAQ · Los Angeles County
How does active fault proximity in Los Angeles County affect where I need survey control points placed?
Alquist-Priolo Earthquake Fault Zone requirements in California can restrict structure placement within 50 feet of an active fault trace. Accurate control point placement lets your geologist and engineer map fault setback lines precisely relative to proposed improvements. We set control in positions that give your licensed geologist reliable reference geometry for fault trench and setback evaluations without relocating control mid-project.
Los Angeles County has dozens of separate municipal jurisdictions. Does that affect how boundary surveys are performed or recorded here?
Yes. Recordation requirements and parcel map procedures vary between the County's unincorporated areas and incorporated cities such as Long Beach, Pasadena, or Santa Monica. We research recorded deeds, tract maps, and assessor data relevant to the specific jurisdiction, then prepare deliverables consistent with California survey law under Business and Professions Code Section 8700 et seq. and the requirements of the applicable local agency.
We're building on a hillside lot subject to California's grading ordinance. What survey deliverables do I need before the grading plan is prepared?
A topographic survey capturing existing ground elevations at sufficient density, along with located property lines, easements, drainage features, and existing improvements, is typically required before a grading plan can be drafted. The survey establishes the baseline from which cut-and-fill volumes are calculated and retaining wall locations are set, giving the civil engineer verified existing conditions rather than relying on GIS or aerial data.
