There are many, many species of Eucalyptus. But I don't expect you to know what it is given it's not native to your area.
I asked the location in part because I didn't think you were from Australia. So thanks, and I know there have been plenty of Eucalyptus planted in California and elsewhere (with the issues that often arise when something not endemic is introduced).
I reckon it is Corymbia citradora. The lemon scented gumtree. I'd base that on the white trunk, the distance from the bottom to the first branches and the length and shape of the branches before clusters of leaves develop. The photo makes the most of all those details and gives a dark blue sky to set them off.
PS. Usually I like a thin black border around photos but the white works beautifully in picking up the trunk with this image.
Y'all missed my previous note? I'm pretty sure it is Corymbia citriodora. It's a tree I know well. I base that on the colour of the bark, the length of the trunk to the lower branches, the shape of the branches and the leaf clusters positioned out on the ends of those long weirdly shaped branches.
