How do heritage & protected trees rules compare between Chino, CA and Rialto, CA?
Chino and Rialto have similar restriction levels.
Chino, CA
San Bernardino County
Chino does NOT have a heritage tree ordinance. There is no city-maintained list of heritage trees, no DBH (diameter at breast height) threshold for protection, and no special permit required to remove a large or historically significant tree on private property. This is markedly different from neighboring Chino Hills, which protects any tree 44 inches DBH or greater under CHMC Ch. 16.90 — a Chino Hills rule that does not extend into Chino city limits.

Chino FAQ
Does Chino have a heritage tree list?
No. Chino has no heritage tree ordinance, no protected-tree registry, and no diameter threshold for special permitting on private property.
I read that you cannot cut a 44-inch tree in Chino — is that true?
That rule is from Chino Hills (CHMC Ch. 16.90), a separate city. It does not apply within the City of Chino limits.
Are any trees protected at all?
Trees on public right-of-way and trees required by a development approval/landscape plan are protected through Public Works and Community Development. Mature oaks affected by a new development can also trigger California's Oak Woodlands Conservation Act review.
Rialto FAQ
Does Rialto protect old oaks or sycamores on private property?
There is no general Rialto ordinance protecting mature private trees by age or species. Protection only applies if the tree is in the right-of-way or part of an approved landscape plan.
Can I petition the city to designate a heritage tree?
Rialto has no formal heritage-tree designation process. You can ask the Planning Division and City Council to consider one, but no current code chapter authorizes such designation.
What protects mature trees on commercial sites?
Trees shown on approved Title 18 landscape plans must remain or be replaced to the satisfaction of the Planning Division - that is the practical 'heritage' protection for commercial property.
