Contra Costa County

Here is what the County has to say about removing trees:

“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. Each tree removal permit is subject to individual consideration and approved or denied on a case by case basis by the Planning Division. 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”
