Humble Beginnings

In 1978, Wyatt Johnson founded Wyatt Johnson, PE, LS Land Surveying. This company focused on the surveying business which included boundary and mortgage (now called Surveyor Location Reports) surveys. In time, and with additional employees, the business name changed to 40th Parallel Surveying and offered ALTA/ACSM surveys and civil site design services.

Modern Surveying Services and Technology

With an eye to the future, 40th Parallel Surveying was among the first surveying companies in Central Indiana to acquire GPS real time surveying equipment and robots. This dedication to modern technology and equipment has continued to be at the forefront and is essential to providing accurate and timely surveys.

Expanded Areas of Knowledge

In addition, our expertise has expanded to meet the increased demands that have been placed on local governments and contractors by various state and federal agencies. We now coordinate wetland delineation and prepare erosion control plans. We design residential and commercial subdivisions that require road, sanitary sewer, storm sewer, water line and erosion control design, along with coordination of utilities.

Superior Reputation

Widely respected in the industry, our projects have taken us all over Indiana, from Tell City to North Vernon, and from Portland to Vincennes, with the majority of our projects being in Howard, Tipton and Hamilton Counties. Our services have included design of sites for fast food restaurants, banks, shopping centers, transfer stations, office buildings, funeral homes, car lots, manufacturing and sanitary sewer lift stations.


We can provide names of various professionals that your project might need such as: architects, structural engineers, wetland specialists, geotechnical engineers and soil scientists.
