When you say you're "on a new job," what kind of job?
Re the dead creeping rosemary, since the one behind it is alive, my first question would be why is this one dead? A gap or malfunction in the irrigation system, if there is one? You could start by cutting it back to see if there is any living tissue near the base. If so, it could grow back. It clearly hasn't been maintained for quite awhile.
...which is odd, because every other shrub visible in those photos is over-pruned. Someone, either the owner or a bad landscape-maintenance firm, has buzzed those shrubs with no regard to their natural growth habits. In particular, that poor Abelia, which shows its beauty growing like a fountain rather than like a lollipop.*
Because I don't know what your job is—are you the new maintenance firm?—it's hard to advise, but in general I agree with Luis: find out what the owner wants.
*Yeah, one of my five pet peeves: that kind of shrub pruning. I do realize that some people like the way it looks
