Backyard Wedding Sacramento I Am Looking For The Name Of A Particular Type Of Tree.?

I am looking for the name of a particular type of tree.? - backyard wedding sacramento

A street near my house has a lot of this type of tree. It has beautiful colors of autumn and February to mid-March to mid-term or if there are many small white flowers. Meanwhile, trees called marriage, but do not believe that the official name. They are medium sized trees, I think 10-20 meters wide and maybe 30-45 feet. These estimates simply because they do not actually measured. If I live in the region north of Sacramento, California. If anyone knows the name that would be very grateful. I am currently the trees in my garden. Thank you!
