We find the line and then we build to it.
Kestrel Barrow is a land surveying and civil engineering firm on Bannock Street in Boise. Boundary and ALTA surveys, platting, grading and drainage, roads and utilities, and drone mapping for developers, ranchers, highway and irrigation districts across southwest Idaho and eastern Oregon.
A boundary is a claim. We bring the evidence.
Kevin Moreau and Hana Sorensen opened the firm in 2003 in a rented room above a print shop on Bannock Street, with one total station and a borrowed plotter. Surveyor and engineer under one roof was the whole idea: the person who set the corner sits down the hall from the person who drew the pipe to it.
Twenty-six people later, we still work that way. Field notes get read by the designer, and design changes go back to the crew chief before anyone drives a stake.

Plain-language guide
Before you hire a surveyor.
What a boundary survey actually is, why a record of survey matters, what monuments look like in the ground, and what it should cost you. Written by the crew chiefs, not marketing.
We get the same eleven questions every week. The guide answers them with ranges and examples, so the call with us can be about your property.

They found a 1911 corner call that two earlier surveys missed. The neighbor's fence sat 14 feet onto our ground and we had the paper to show it.

Stakes were in before the excavator showed up, and the cut sheet matched the plan set. Plenty of firms cannot say that about their staking.
