Here are the links for the 3 Counties in the Portland Metro area:

Multnomah County
Here is a helpful quote from Multnomah County:
“Legislative Changes
Measure 50, passed by voters in May, 1977 has significantly changed the property tax system. Under the new State Legislation, Oregon taxes are now based on tax rates with several caps on taxes, rather than on valuation which created the tax rates. Measure 50 also eliminated the six year reappraisal cycle which required a physical appraisal of all properties once every six years. Measure 50 created a new tax limit for property, called the “Maximum Assessed Value.” This value can only increase 3% annually unless there have been improvements to the property. However, the assessor must continue to determine “real market value” of properties to determine compliance with Measure 5, which sets an additional limit. Some properties in Multnomah County will have tax limits determined by Measure 5.
