Voters in Wasco, Hood River, Sherman, and Gilliam counties are being asked by Northern Oregon Corrections during the May 16 election to establish a permanent property tax rate of 26 cents per $1,000 of assessed property value for operation of the regional jail.  The rate mirrors the construction bond rate to build the facility which came off the tax rolls in September.  NORCOR and        Wasco County County Commission board chair Rod Runyon says the board is looking to stabilize its revenue picture, which currently involves funding from each county along with various contracts with other entities including Immigration and Customs Enforcement that fluctuate over time.  The permanent tax rate would generate about $1,300,000 per year, which would be on top of what the $3,800,000 the four counties currently pay annually to operate the facility.
