What size trees are protected? 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).  A tree within the Austin city limits is protected once it reaches 19 inches.  Diameter = Circumference / 3.1416 and Circumference = Diameter X 3.1416.

What is the review process for a tree removal permit? 

• When development of a residential property contains a protected size tree, the tree review will occur simultaneously with the residential building plan.  The tree permit will be created along with the residential building permit.
• When a protected tree is not development-related, but impacted by utility issues, disease or other conditions, a Tree Ordinance Review Applicaton is required.

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.
