What is happening here? Evergreen "leaves" do not live forever. They are constantly being replaced. Most notably in late summer or fall there will be some old material turning brown and falling. This is sometimes call flagging or fall foliage drop. Some is normal as shown above. In the Northwest the event is more pronounced after a very wet spring and a dry late summer.
The second example, however, is not normal. In a matter of a month or two the entire tree turned brown and died. Unfortunate, but this does happen once in awhile. The tree will need to be replaced, the irrigation system checked to ensure adequate water is reaching the root zone of the replacement plant.
