Checking easements on a house in Boardman? What you want is the Boardman plat map, since it shows lots, streets and easements as approved. This Boardman guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Getting started with the Boardman plat map

Opening the official parcel viewer

Heppner is the county seat, which is where the courthouse records live. Smaller places on the map include Irrigon, Ione, and Lexington, each with its own cluster of lots. Around 12,302 people call Morrow County home (Census Bureau estimate, 2023) on roughly 2,031 square miles. Morrow County was formed in 1885, which matters when you trace an old farm's title. Features like Columbia River and Umatilla National Forest are easy to spot when you zoom out from Lexington.
Before you lean on the lines
