It doesn't resemble a crApe myrtle to me. I think it would be difficult to positively ID a tree without knowing where in the world it is, what the leaves look like, what the branching pattern is, etc. Any chance of getting decent pictures and letting us know where, in general, these trees are?

Thespesia populneoides is the same plant as Thespesia populnea, it was considered a separate species at one time but has been lumped into Thespesia populnea. Pacific Rosewood and Portia Tree are both common names. A plant could have dozens of common names. Thats why Latin names are used as the Latin name is the "official" name. There could be other plants called Pacific Rosewood so unless the Latin name is used it could be confusing as to what plant is being discussed.

Viburnum lentago.

Good species as it lets a fair amount of light thru the leaves and the grass does well enough under it. Obviously heaving the sidewalk a bit, but any full-size tree will do that planted so close to it.
