Master-Planned Residential Community Survey & Platting
ALTA/NSPS land title survey drafting, boundary retracement, topographic contour generation, and subdivision record plats.
Complex Constructability & Coordination Obstacles
A 240-acre master-planned residential community required processing multi-day GPS survey point coordinates, retracing historical deed descriptions with conflicting boundary calls, and drafting detailed subdivision lot layouts conforming to municipal zoning setback rules.
Key Engineering Responsibilities
- ALTA/NSPS Land Title Survey Drafting with Table A items
- Topographic TIN surface mapping and 1-foot contour generation
- Subdivision platting including 320 residential lots, right-of-ways, and utility easements
- Deed analysis and boundary closure tolerance verification
Our Technical Engineering Approach
We processed raw field coordinate data in Civil 3D, creating structured point groups and automated linework routines. We drafted boundary lines with precise metes-and-bounds bearings and distances, performing mathematical traverse closure checks to ensure strict legal compliance.
Importing PNEZD coordinate files, applying description keys, and generating survey linework.
Calculating boundary closures, resolving title easements, and mapping setback lines.
Modeling TIN surface, drawing breaklines, and labeling index/intermediate contours.
Drafting street centerlines, parcel boundaries, lot numbers, and dimensional tables.
Preparing formal survey sheets with surveyor signature blocks and legal notes.
Final Deliverables Provided
- Layered Civil 3D Survey Drawing Files (.DWG)
- Certified ALTA/NSPS Land Title Survey Drawing Packages (PDF)
- Subdivision Master Plat Sheets with Lot & Curve Tables
- Traverse Closure and Boundary Mathematical Reports
Project Outcome & Value Delivered
Successfully finalized legal record plats and ALTA surveys ahead of project schedule, allowing property title insurance closing without delays.
