Land Surveying

Harmsen & Associates, Inc. has been surveying in the
Puget Sound region since 1974.


In that time we have completed more than 10,000 projects!

Our surveyors are perhaps the most experienced in Washington. Each Surveyor has more than 15 years’ experience, and most have more than 20. Our surveyors understand the geography of this region like the back of their hands! In many instances, we already have surveyed areas and have data in-house that can simplify your survey project, saving you time and money.

Our range covers the Cascade Range to the coast of Washington, the Bellingham area to Olympia. We have worked in Eastern, Central, and Southwestern Washington. We have surveyed for water districts, wastewater treatment plants, roads, municipalities, single family homes to high rises, pits and quarries, watersheds, dams, rivers, commercial, industrial and many other types of projects.

"Please pass on my total happiness with the survey job your team did for me.  I'm really impressed with the clear and precise marking of my property."
~Brian Mogle, Oak Harbor, WA
