I can't tell you where it would be written in regs or fars but Troutdale
coordinates with PDX to direct traffic to turn prior to entering PDX
airspace or to stay below their airspace and flight paths. Heading west
from Troutdale you are instructed to turn before Blue Lake.

If Class C overlaps Class D (see Portland Troutdale airport), which
airspace takes precedence?
