I also live in WA state and practice landscape design there. While there are a number of hardy palms that do well here (there is a massive one in my inherited garden), I find they just look too out of context with our typical PNW landscaping and don't encourage their use. And they are messy :-)

There is an underlying concept of landscape (and architectural) design - genius loci - which means designing with an eye to character or atmosphere of the place/location and plant selection factors into this principle more than just about any other element.

If you do decide to use them, full sun and well drained soil.

Any suggestions on what we can place there? We would like something low maintenance and that would give that section some appeal and privacy from our deck. This section is to the left of our driveway

You have a big selection of broadleaved evergreen shrubs you could choose from.......escallonia, ceanothus, abelia, choisya, pieris, viburnums. All flower, all are much lower maintenance than the palm and come in a range of sizes from big (8-10', maybe more) to quite low and compact (2-3'). Dwarf conifers could work also, as would a mix of broadleaves and conifers.
