Los Angeles County
South Gate does not have a dedicated 'heritage tree' or 'landmark tree' designation in its Municipal Code — unlike Sacramento (Ch. 12.56), Pasadena, or Pacifica which formally protect oaks, sycamores, or trees of historic interest by species and size. Instead, South Gate's Chapter 5.33 treats ALL 'public trees' (any plant reaching 15 ft mature height with half or more of its trunk on public land) as protected — effectively conferring heritage-grade protection on every one of the city's ~15,900 parkway trees regardless of species or age. There is no separate private-property heritage tree registry.

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.
South Gate FAQ
Does South Gate have a 'heritage tree' or 'landmark tree' list?
No — South Gate's Municipal Code (Chapter 5.33) does not designate individual heritage trees by species or size the way Sacramento or Pasadena do. Instead, every public tree (any plant reaching 15 ft mature height with half or more of its trunk on public land) is protected uniformly. A mature signature parkway oak gets the same Chapter 5.33 permit-and-restitution protection as a recently planted street tree.
Is the large old tree in front of my house a 'heritage tree'?
If it is in the parkway strip (between sidewalk and curb), it is a public tree protected by SGMC 5.33 — you cannot prune or remove it without a Public Works permit, and its valuation upon unauthorized removal will be calculated under the WCISA Trunk Formula Method, which produces very high restitution figures for mature specimens.
Can I get a special designation for an old tree on my private property?
South Gate has no private-property heritage tree registry. State law (PRC §4799.06+) authorizes but does not require cities to adopt one. Contact Public Works (323) 563-9500 if you want to inquire about voluntary preservation or species inclusion in the Street Tree Master Plan.
