Opening the Colusa GIS map
In most places the county maintains the parcel layer, which makes the Colusa County ArcGIS parcel map the main source for lots in Colusa.
The free map to start with
Parcels around Arbuckle can be looked up on the Colusa County ArcGIS parcel map, a viewer that needs no account. For a tract near Williams, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Arbuckle, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Colusa and the county around it
Colusa is part of Colusa County, California, which means parcel data comes from the county. As the county seat, Colusa hosts the courthouse, which puts the County Recorder close by. If the land is near Arbuckle, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits toward Arbuckle generally follows county rules instead.
Legal descriptions in California
California is laid out under the Public Land Survey System, so rural legal descriptions near Arbuckle cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Arbuckle odd-sized. Keep the legal description for land near Arbuckle before you request a deed or survey.
Search tips
Vacant ground near Williams may lack an address, so pan the aerial and click the lot. For acreage around Grimes, a parcel ID is the most reliable search, and it's printed on tax bills.
Before you lean on the lines
Acreage on the record is an assessed number; only a licensed surveyor establishes the real corners for a parcel near Grimes. Owner names and values update on a schedule, so a fresh transfer around Grimes can take weeks to appear.
Backing up the map with records
For anything that matters, get the recorded deed from the County Recorder; the parcel line is a drawing of it, and that holds around Arbuckle too. Long-held tracts around Williams can trace back through several deeds, so a title company is worth hiring before a purchase.
Saving what you find
Save a screenshot of the lot near Arbuckle and its record panel, which helps later when you ask the assessor or a title company.
Layers worth turning on
On ground around Grimes, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
Field tips

Reading a parcel record

Troubleshooting the viewer
If the viewer stalls on a phone near Grimes, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
