"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.
