  • MacKay-Sposito-Land-Survey-banner-photo

MacKay Sposito has provided land surveying services since we were founded in 1974.
We have one of the most experienced private land surveying teams in the Pacific Northwest, capable of serving a variety of industries over a broad geographic range that includes Washington, Oregon, Idaho, Montana, Utah, and California.

There are two sides to land surveying, both equally important. Our field surveyors map all the topographic elements of a piece of land, while back at home our office personnel map out the legal complexities of land rights and ownership. Together, we ensure you have a record that will withstand the tests of time and scrutiny. You can trust designs that are based on our maps.

In addition, our team has the security clearances necessary to work at ports, Federal Aviation Administration (FAA) airports, and electrical power facilities. We also have our FAA 333 exemption and a licensed pilot on staff in order to provide professional surveying services with unmanned aerial vehicles (UAVs), a.k.a. drones. With this expertise, our willingness to travel, and our focus on safety, there are very few assignments our team would shy away from. It's a mix that gets your project started off on the right foot.
