Chino FAQ
Can I trim the parkway tree in front of my house in Chino?
Parkway trees that are city-owned cannot be removed or substantially pruned without a permit from the city's Public Works/Community Services Department. Homeowners may perform light pruning of overhanging private branches but should not top or cut into the structural framework of a city tree.
What about trees near power lines?
Do not trim near energized lines. Call Southern California Edison; line-clearance crews handle clearance around overhead conductors under CPUC GO 95.
Ontario FAQ
Can I trim the city tree in front of my house?
No. Parkway street trees are city property. You must request trimming through Ontario Public Works or obtain a permit before any work.
Can I cut my neighbor's branches that hang over my yard?
Yes, up to the property line under California common law, but only if you do not harm the tree's overall health.
