El Monte FAQ
Is my backyard tree a Heritage Tree?
If it is not a California native and its trunk circumference is at least 36 inches measured at 4.5 feet above grade (or combined 75 inches for multi-trunk, or it is at least 35 feet tall), yes — EMMC §14.03.020 designates it as a Heritage Tree and a Protected Tree.
Can I top a Heritage Tree to keep it short?
No. Topping, lion-tailing, and removing more than 25% of foliage are explicitly prohibited under EMMC §14.03.030(B) and (F), and are subject to fines and penalties even when done by a tree service. Routine pruning must follow ANSI A300 standards.
Are trees in a backyard grove protected?
Yes, EMMC §14.03.020 specifically protects "any stand of trees the nature of which makes each dependent upon the others for survival" as a Heritage Tree.
