Certified forester determines it is a rare or unusual species or of exceptional quality. ii. A smaller tree can be considered a heritage tree if it is specifically used by a developer as a focal point in the project. 4. Other Trees: A tree not included on Table 1011-1 or Table 1011-2 may be included for credit as part of the Tree Inventory subject to City approval if it has: a. A life expectancy of greater than 10 years; b. A relatively sound and solid trunk with no extensive decay or hollow; and c. No major insect or pathological problem; and if d. A certified forester determines it is a rare or unusual species or of exceptional quality; or e. It is specifically used by a developer as a focal point in the project. E. Tree Protection: All trees which are to be retained on any site shall be marked and physically protected from harm or destruction caused by soil compaction, equipment and material storage within the drip line, bark abrasions, changes in soil chemistry, out -of -season pruning, and root damage during construction. 1. Before any construction or grading of any development project occurs, a "safety fence" at least 4 feet in height, and staked with posts no less than every 5 feet shall be placed around the drip line borders of woodlots and/or the drip lines of significant trees to be preserved. Signs shall be placed along this fence line identifying the area as a tree protection area, and prohibiting grading beyond the fence line. This fence must remain in place until all grading and construction activity is terminated. 2. No equipment, construction materials, or soil may be stored within the drip lines of any significant trees to be preserved. 3. Care must be taken to prevent the change in soil chemistry due to concrete washout and leakage or spillage of toxic materials such as fuels or paints. 4. Drainage patterns on the site shall not change considerably causing drastic environmental changes in the soil moisture content where trees are intended to be preserved. 5. Pruning of oak and elm tree branches and roots must not take place from May 1 through July 31. If wounding of oak or elm trees occurs, a nontoxic tree wound dressing must be applied immediately. Excavators must have a nontoxic tree wound dressing with them on the development site. 6.

Allowable Tree Removal: 1. Pursuant to an approved tree preservation plan, significant trees may be destroyed without any required replacement within the width of required easements for public streets, utilities, and storm water ponding areas. 2. Development of Vacant Lots: On individual lots, up to 35% of the total DBH-inches of all significant trees and up to 15% of the total DBH-inches of all heritage trees may be removed for the installation of utilities, driveways, and the building pad without tree replacement or restitution. 3. Redevelopment of Lots: On lots which have been previously platted and developed, where the structures have been removed or destroyed to more than 50% of the current market value, up to 35% of the total DBH-inches of all significant trees and up to 15% of the total DBH-inches of all heritage
