2011 ORS § 308A.062¹
Qualification of exclusive farm use zone farmland
(1) Any land that is within an exclusive farm use zone and that is used exclusively for farm use shall qualify for farm use special assessment under ORS 308A.050 (Legislative intent) to 308A.128 (Certain district assessments inapplicable to exclusive farm use zone farmland), unless disqualified under other provisions of law.
(2) Whether farmland qualifies for special assessment under this section shall be determined as of January 1 of the assessment year. However, if land so qualified becomes disqualified prior to July 1 of the same assessment year, the land shall be valued under ORS 308.232 (Property to be valued at 100 percent real market value and assessed at assessed value), at its real market value as defined by law without regard to this section, and shall be assessed at its assessed value under ORS 308.146 (Determination of maximum assessed value and assessed value) or as otherwise provided by law. If the land becomes disqualified on or after July 1, the land shall continue to qualify for special assessment as provided in this section for the current tax year. [1999 c.314 §5]
