Land Surveying in New Orleans, LA
Surveying in New Orleans means measuring a city in motion. Subsidence is continuous and uneven, benchmarks sink with the ground they mark, and elevation, for flood insurance, for levee clearance, for simple drainage, is the product everything else depends on. Boundary work carries its own depth: French and Spanish arpent lots radiating from the river, colonial-era conveyances, and a recording tradition unlike common-law states. Survey services here are provided project-by-project through professional land surveyors licensed in Louisiana, covering boundary and ALTA work, elevation certificates against current datums, topographic surveys for design, and construction staking with as-builts for pile-supported work.
Continuous subsidence makes datum currency the central technical issue in New Orleans elevation work; benchmarks must be verified against actively maintained control because the published values age faster here than anywhere in the region.
- Boundary and title surveys for acquisition and permitting
- Topographic surveys for civil design
- Construction staking: building corners, utilities, paving, and grades
- As-built surveys for closeout and conveyance
FAQ · New Orleans
Why do elevation certificates here expire in practice?
Because the ground keeps moving. A certificate is a snapshot against a datum, and when both the structure's grade and the benchmarks themselves subside, insurers and floodplain administrators reasonably want current measurements tied to maintained control.
What are arpent lots and why is my parcel shaped like a slice?
French colonial land division: narrow frontages on the river or bayou running long and deep behind, so every holding touched the water. Those original lines still control boundaries across the region, and resolving them is historical research as much as fieldwork.
