Carson FAQ
Does Carson designate specific 'heritage' or 'specimen' trees?
No — Carson does not maintain a named heritage-tree list in its Municipal Code. All parkway and right-of-way trees are equally protected under Article 3 Chapter 9, and a large mature tree's value under the CTLA Guide for Plant Appraisal can far exceed $1,000, so the penalty scales with the tree.
Can a developer remove a mature tree during construction?
If the tree is in the parkway or city right-of-way, the developer must obtain Public Works approval under Chapter 9 and follow any replacement direction from the Public Works Division. For trees on private property, no city-wide private-tree permit applies, but check zoning landscape conditions of approval under CMC Article IX.
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.
