Riverside County does not publish parcel acreage, so these are ranked by the area of each parcel's mapped boundary. That is a close match for deeded acreage — the median of the two agrees where counties publish both — but it is not the deed, and it will differ where a deed runs to the centreline of a road or where several units share one footprint.
