It would help to know how many acres of Exclusive Farm Use land are under the red and green zones in the corridor map. You can find this information on your recent tax notices. It will say *ZONED FARM USE-POTENTIAL ADD TAX.
You can also find this at the Malheur County Assessor's Office Property Search site at http://malheurco.org/ by name or tax lot to see if it is designated EFU.
UPDATE Pat Phillips adds this comment: Folks, pretty much anything below the canals is zoned EFU, above the canals is ERU (exclusive range use) except for what is inside a city limit line. It does not have to have irrigation water to be zoned EFU. The soil classifications are 1 through 8, with 1 thru 6 considered good farm ground, 1 being highest. We have very little 7 & 8, especially 8 close in to Ontario, Nyssa, Vale. Most of the 7 & 8 is out like the hills around Harper and Brogan. We have soil maps of the county in our office.
