Land Surveying

Professional Land Surveying is a cornerstone of Stahly Engineering’s services. We have been providing survey and construction staking services since our business began in 1970. The ability to provide any type of survey for each project that we undertake compliments our design process. Stahly Engineering is known for providing practical, buildable designs; these designs rely upon thorough and accurate data provided by our Land Survey Department.


A large portion of our land survey projects include property boundary or public land survey system elements.  With rivers, lakes, Tribal lands, homestead entries, mineral patents, and vast land expanses still described within the U.S. Public Lands Survey System in the state of Montana; finding, mapping and describing boundaries is a major part of what we do.

Unmanned Aerial Vehicle (UAV) Survey Services

In order to help our firm grow, the survey team continues to keep up to date on the latest technological tools and advances. The most recent innovation in which Stahly has invested is our Unmanned Aerial System (UAS) with Klau Post-Processed Kinematic (PPK) technology. We utilize our highly sophisticated UAS in order to provide accurate survey products to our clients in an efficient and cost-effective manner. The centerpiece of this system is a PPK GPS receiver and pre-calibrated camera onboard the UAV. Unlike other photogrammetric methods commonly used throughout the industry, this system eliminates from our workflow the methodical setup of numerous ground control points, saving hours of on-the-ground field time and making it more cost-effective than conventional survey methods. 

Recent Projects:

Montana Department of Transportation Term Contracts

Stahly Engineering holds term survey contracts with the Montana Department of Transportation (MDT). Surveys performed for MDT include control, right-of-way, cadastral, topographic, and hydraulic surveys. We recently completed an extensive topographic survey of West Yellowstone and prepared Microstation drawings to be used by the department in determining MDT right-of-way and identifying needed ADA upgrades to sidewalks. Other recent MDT surveys include:

  • Westby West: Control establishment, Cadastral/Existing Right of Way, topographic/hydraulic survey for 8.7 mile highway project.

  • 3 Mile Creek: topographical and hydraulic survey for reconstruction of bridge over 3 Mile Creek.

  • Havre Streets: right-of-way retracement surveys for 3 roads in Havre

  • Spider Lake: set new control and topographic survey for Spider Lake Road reconstruction.

  • Dutton East: topographical survey of 14 miles of existing road rehabilitation.

  • Marysville Road Survey: survey for reconstruction of 7 miles of Marysville Road.

Natural Resource Conservation Service Contracts

Stahly Engineering has performed over 20 land surveying and mapping projects across the state for the NRCS.  Setting the bar on the correct way to record and perpetuate wetland and upland conservation easements, the NRCS uses Stahly to define, mark, map, and produce exhibits that describe easement location, boundaries, and size.  Stahly also provides GIS products as part of these land surveying projects.

University Housing Project

A multi-year, phased project across from the MSU Bobcat Stadium, our survey department provided:

  • Pre-design topographic, wetland, and boundary mapping.

  • Subdivision Planning and Platting.

  • ALTA/ACSM Land Title Survey.

  • City of Bozeman Easement Exhibits.

  • Aerial inspection and mapping photography.

  • Construction staking.
