The Permit Process: Step by Step
Determine if your tree is protected
Check if it's an oak on a developed parcel (12"+ diameter), a native riparian tree (4"+), or designated on a development plan. Contact Planning at (925) 253-4210. Check if any permit exceptions apply (hazardous condition, MOFD requirement).
Get an arborist assessment
An ISA Certified Arborist report or written statement is required for most protected tree removals. The report should document species, size, health, and removal justification.
