When a listing near St. Helens mentions a lot number, the Scappoose plat map is where those numbers come from. What this Scappoose guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Who keeps the Scappoose plat map
For land around Columbia City, look for the plat book reference on the parcel record; use it to request a copy.
Getting to the right map
Begin with the ORMAP statewide tax lot viewer; it includes each tax parcel in the county, St. Helens included. When a rural tract has no street number, pan along US Route 26 and click the parcel itself. Out toward Prescott, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Where Scappoose fits in
Scappoose lies within Columbia County, Oregon, and the county assessor maps its lots. Around Prescott, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the town limits near Vernonia usually follows county rules instead.
Amended plats
Lots near Vernonia can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Getting answers from the right desk
If the acreage or value on a parcel near Vernonia looks off belong with the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Clatskanie are for the local planning and health departments, and the answer depends on jurisdiction.
Getting your bearings
St. Helens holds the county offices, which is where the courthouse records live. You'll also find Columbia City, Vernonia, and Prescott, where town lots give way to larger tracts. About 53,880 people live in Columbia County (Census estimate, 2023) on about 659 square miles. Columbia County dates to 1854, which matters when you trace an old farm's title. Features like Julia Butler Hansen National Wildlife Refuge are easy to spot when you zoom out from Vernonia.
Plat map vs. parcel map
Where lines don't match in Scappoose, go with the plat and a surveyor's work.
Land outside a subdivision
Rural land near Clatskanie that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Recorded documents worth pulling
Before you sign anything, get the recorded deed from the County Clerk; the parcel map near Prescott only summarizes it. Long-held tracts around Vernonia can trace back through several deeds, so a title company can sort it out on a real sale.
Before you lean on the lines
Listed acreage is an assessed number; just a licensed surveyor establishes the real boundary on land around Vernonia. Records update in batches, so a fresh transfer around Vernonia may not show yet.

Easements on the plat near Rainier can block a shed or pool; read the notes on the sheet.
Online indexes and office visits

Next door to Columbia County
Columbia County touches Clatsop County, Multnomah County, Tillamook County, Washington County, and Clark County, WA, all with their own assessor records. Ground near St. Helens that runs to the line can be split in two county records, so look at the neighboring map before you assume the acreage.

Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Vernonia vary in size. Write down the legal description for the tract near St. Helens before you request a deed or survey.
Taking the map into the field
