As I have said on my post on the beautiful streetscape of Central Market, there should be planets. It don't have to be just one kind of tree it can be mixture of different ones like maybe these:
Pygmy Date Palm
Flax (Phormium) Tricolor
Some of the trees can even have a flower bed around them.

For the trees that don't have a flower bed around them, it can have a tree grate or tree guard around it. Also some of the trees should have rope lights around them, so the neighborhood look nice at night.
Friends of the Urban Forest website - www.fuf.net/ can even be the one to do the planting add the rope lights to some of the trees and so on. IF allow by whoever will be the ones that has the final say on it.
It would be nice to have benches in Central Market. But don't limit it just to one kind or type. Maybe like two or three kinds, and every so often it this one or that one.
