Where the parcel data lives
Your first stop is the ORMAP statewide tax lot viewer; it maps each tax parcel in the county, Echo included.

For acreage around Echo, write down the parcel ID while you have it open; each records desk in the county will want it.
Offices that can help
For assessment questions about property around Pendleton belong with the County Assessor, since that office keeps the assessment data. Questions about what you can build around Echo go to planning, building or health offices, and the answer depends on jurisdiction.

Hermiston, OR: the basics
Hermiston is part of Umatilla County, Oregon, so its parcels are on the county's map. Out toward Echo, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits out by Adams usually falls under county rules rather than the town's.
Before you lean on the lines
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real corners on land around Umatilla. If you're looking near Athena, records update in batches, so a deed recorded last month might lag behind.
Amended plats
An amended plat may change lots around Athena, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.

Land outside a subdivision

How land is described here

Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Umatilla, but coverage can be spotty out of town. A screenshot of the parcel near Echo with its ID is a good backup.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
