Evergreen tree turned yellow/brown
A few months ago the tree started yellowing and has gotten progressively more yellow/brown colored. The needles seem slightly crunchy to the touch though not totally dead feeling. Not sure what is wrong with it. There are a few patches of green but it's pretty uniform yellow color.

Your tree appears to be a Port Orford cedar (Chamaecyparis lawsoniana). And based on the symptoms, it is very likely that it is afflicted with the root disease Phytophthora lateralis. Unfortunately, this introduced pathogen is deadly on Port Orford cedar, causing rapid mortality in otherwise healthy trees. For more information on the disease, see the reference in the PNW Plant Disease Handbook
