Properly trimmed tree

Proper tree trimming techniques maintain healthy trees which release clean air into the environment. Proper techniques include removing no more than 25% of a tree.

Improperly trimmed tree with "topping"

Improper tree trimming techniques cause trees to become weak, creating a potential safety hazard.

Introduction

A tree pruning permit is required before pruning or trimming trees on commercial property in Cerritos. The permit process helps manage the local urban forest and prohibits the improper maintenance of trees on commercial properties within the City.

Over the years, some local businesses have “topped” their trees as a means of cutting maintenance costs. (“Topping” trees involves chopping branches severely to reduce the tree’s size). Topping gives trees ugly stumps and raw cuts that invite insects and disease. Topping also starves trees by robbing them of their food-making ability, which will cause most of them to quickly grow ugly, brushy regrowth that requires frequent trimming. “False limbs” (branches with weak connections that can easily break) may also grow out of topped trees.

The City ordinance requires a tree pruning permit for any entity wishing to prune or trim trees within commercial, industrial and multi-family zoned areas, as well as common areas within all residential developments that are governed by homeowners associations. When an entity requests a tree trimming permit, the City will send a certified arborist to meet with the tree trimmer to explain proper tree-trimming techniques.
