I would like to know what these trees are, or even names for varieties that would grow the same way: fast and medium tall with foliage all the way down, to form a narrow leafy screen, not a long bare trunk or very broad and wide.

These are growing in WA state, Issaquah, around 15-20 mile inland, but they are almost certainly imported, not local varieties.

Thanks in advance!

I'm sorry the attempt to photograph the evergreen greenery failed. They aren't needles, more like fat webbing.

Hard to say for certain, but it could be some sort of Arborvitae (Thuja). They commonly grow in a conical shape and, even when they don't do it naturally, are often pruned into that form.

Thanks, Kent. I think you're right. I guessed that, when someone knew the right name, it would be a recognizable, mainstream landscaping name. "Arborvitae" sounds right.

These "leaves" or "needles" look exactly right:
American Arborvitae (Thuja occidentalis 'Rheingold')

This form looks about right:
Eastern Arborvitae (Thuja occidentalis 'Smaragd')

Hi Rick,
Would something like Ilex crenata 'Sky Pencil" work for you? They are pretty neat evergreen hollies.

I have Sky pencil Holly. They grow really slooooooowly. Beautiful and Slooooooowly.

That Sky Pencil Holly looks lovely and has the right shape, but Becky would want the screen established all the way up to deck level ASAP.

Also, amazingly, I see that someone thinks it would be invasive in WA, at least in Snohomish and King Counties!
