Because it is in the Pacific Northwest.

Western Oregon gets frequent rain from the ocean and its latitude frequently putting it directly under the jet stream. But much of eastern Oregon is considered desert, due to the rain shadow of the Cascade range.

It doesn't rain that much in Oregon, depending on where you are in Oregon and what your idea of "much" is. The coastal range causes humid ocean air to rise, cool, and create heavy precipitation. A similar effect happens with the Cascade Range providing lots of rain in the Willamette Valley. On the other side of the Cascades, most of Oregon is high plains desert and fairly dry.
There are many places that get more inches of rain. Houston, TX averages about 50 inches of rain every year. The Willamette Valley averages about 40 inches of rain every year. The difference is that in Houston the sky opens up and it showers hard. In the Willamette Valley it drizzles and sprinkles a lot. As the saying goes, it's not the inches of rain, it's the hours of rain in Oregon.
