A protected size tree is determined by measuring the tree trunk at 4.5 feet above ground. This is commonly known as DBH (diameter at breast height). The tree, within the Austin city limits, is protected once it reaches 8 inches in diameter (19 inches at a single family home). Diameter = Circumference / 3.1416 and Circumference = Diameter X 3.1416.
What is the purpose of a tree survey?
A tree survey tag is usually an aluminum circular or rectangular label attached to the tree trunk. A tag is used for physically identifying a tree with a specific number. This number is referenced on a site plan or survey. It does not mean the tree is marked to be saved or removed.
Who do I call if I have a tree removal question?
The City Arborist (512) 974-1876 should be contacted if you have a tree removal question. If the tree is on public property contact the Parks and Recreation Department.
