Registered heritage trees, trees that provide land stability, are of a protected species or size, or provide visual screening/and or privacy are subject to tree removal permits. 

Some factors used to determine tree removal approval include hazardous situations, number of trees on a property, damage to existing structures, and reasonable development. Prior to removing any tree on your property, you are advised to contact the Planning Division at (925) 674-7205 to verify your tree does not require a removal permit.
