9-1N-8: TREE REPLACEMENT REQUIREMENTS:

A.   Trees protected by covenant between the city and the property owner:

   1.   Must not be removed without permission of the city;

   2.   Must be trimmed under the guidance of a licensed arborist;

   3.   Must be maintained in good health (every reasonable effort must be made to maintain the tree); and

   4.   Must not be topped (topping of a tree may constitute a removal if the structure is significantly affected).

B.   If a property owner removes a tree protected by covenant, a replacement tree or trees must be provided per Table 9-1N-1. If the replacement tree or trees cannot be provided onsite due to insufficient space, then alternative requirements, such as donation of the tree or trees to the city for planting in the parkway along with reasonable costs for staff time to purchase, plant and maintain the tree for three (3) years may be provided.

*Add half of the difference between the two to the narrowest measurement for the average canopy. **Replace the tree with a combination of both Tree Canopy and Tree Value Standards. The appropriate standard should be set by the City Arborist. Note: Basis of this table is determined by the growth of one 24" box size tree, growing at a rate equivalent to 9 feet of canopy over the course of ten years.
