Anything out of the ordinary this year with borers in evergreens?

Just removed a dead Port Orford cedar for someone yesterday, and thought it was probably Phytophthora. As soon as I cut some limbs away, it was evident that borers infested it.

Last spring, I planted 2 Hinoki Cypress at one small project in a west Portland suburb. Two weeks later, I noticed one turning gold. Looked inside the canopy and could see the fine dust and holes above many of the limbs. Won't say which nursery I bought them from, but when I went back, there were upwards of 2 dozen Hinoki's in a few rows with the same problem. They went ahead and gave me a replacement no-charge.

Anyhow, I haven't seen any borer damage on evergreens in the past few years, but lately, twice in just a few months.
