Protected trees
On sites 2 acres and larger without a recorded tree conservation area, no tree disturbing activity (except minor tree removal) is allowed in a 32-foot perimeter buffer next to vacant property, a 65-foot buffer next to a non-thoroughfare road or non-vacant property, or a 50-foot buffer next to a thoroughfare. In those buffers no tree 10 inches DBH or larger may be removed, except up to 5 trees between 10 and 22 inches DBH in a continuous 5-year period with a city permit. Champion trees and their critical root zones may not be disturbed. Trees in recorded tree conservation areas need a tree conservation permit.
