Tree Alert

Four seemingly healthy street trees, about 6" diameter at breast height, have been severely cut; the crowns have been removed and branch stumps and trunks are all that remain. The trees are located in front of a yellow house on Stuart between Telegraph and Ellsworth. The trees bear no orange paint, the typically marker for tree removal made by tree professionals (as is the case for a purple-leaf plum across the street). I cannot identify the species; I am still a novice at Bay Area tree identification, so I would appreciate help from a reader. Photos of the leaf and fruit are included below.
