Z A tree certified, in a written report, as dead, terminally diseased, damaged, or otherwise dangerous to persons or property by a licensed
landscape architect, or certified arborist, and approved by the City.
3 Critical areas, such as wetlands, streams, floodplains and protected slopes, are defined in RMC 4-3-050.
"Count only those trees to be retained outside of critical areas and buffers.
s The City may require modification of the tree retention plan to ensure retention of the maximum number of trees per RMC 4-4-1301-17a.
6 When the required number of protected trees cannot be retained, replacement trees, with at least a two-inch (2") caliper or an evergreen at least
six feet (6') tall, shall be planted. See RMC 4-4-130.H.1.e.(ii) for prohibited types of replacement trees.
