Land Surveying in Dakota County, MN

Minnesota design frost depth commonly runs 42 to 60 inches in the Twin Cities region. Frost heave can displace both existing monuments and freshly set stakes, particularly in saturated clay-heavy soils common in parts of Dakota County. We account for this by timing critical staking phases to follow thaw and ground stabilization, and by scheduling re-checks of control points at key construction milestones rather than assuming initial stakes hold throughout a long project.

Discrepancies between recorded plat geometry and recoverable monument evidence are resolved through a deed and record search, proportionate measurement methods per Minnesota statute, and professional judgment by the licensed land surveyor of record. We document conflicting evidence in the survey record so that the licensed surveyor's decision is transparent and defensible to Dakota County reviewing agencies or in any title process.

Topographic surveys are delivered as CAD files with spot elevations, breaklines, and contours at the interval your design team specifies — typically one-foot contours for grading and drainage design. Data is tied to NAVD 88 vertical datum and a state plane or project-specific horizontal datum. We confirm datum and format requirements with your engineer before fieldwork begins so the data integrates directly into your design model.
