2. CITY shall not require prior notice from EWEB for "isolated" trouble- <br /> related trimming required for restoration of service, immediate threats <br /> to service reliability or trimming done in response to immediate public <br /> safety concerns. <br /> 3. Once prior notice is given, EWEB and CITY staff shall meet to evaluate <br /> the impact this work will have on the specific trees and reach an <br /> agreement on the extent of work to be performed. <br /> 4. A public notification plan will be developed based on the magnitude of <br /> the work being performed. This plan may include but is not limited to: <br /> a. notice to abutting property owners <br /> b. notice to interested EWEB Board /City Council members <br /> c. notice to Neighborhood Organization <br /> d. news release <br /> 5. In the case of emergency where EWEB needs to perform work which impacts <br /> trees under City jurisdiction to eliminate an immediate threat to life <br /> or property, City waives the requirements of B -1, B -3, and B -4. Where <br /> EWEB has impacted trees under this provision, they shall notify City of <br /> work performed within two working days of the incident. <br /> C. POWER LINE CLEARANCE PRUNING <br /> EWEB and CITY agree that the method of pruning has impacts on both the health <br /> of the tree and the public perception of its aesthetic value. Therefore, both <br /> parties agree to the following: <br /> 1. "Directional Pruning' shall be the preferred method of power line <br /> clearance pruning for use on street trees because of its minimal <br /> detrimental effect on the health of the tree. <br /> 2. Whenever EWEB or CITY are performing pruning on young trees, directional <br /> pruning methods shall be used to "train" the tree to grow away from the <br /> lines to minimize future power line clearance problems. <br /> 3. Where EWEB finds trees which cannot be "directionally" pruned, due to <br /> previous pruning using other methods or due to a tree's structural <br /> inadequacy, then "round over " pruning is acceptable. <br /> 4. If, after one year from line clearance pruning, an abutting property <br /> owner feels the aesthetic appearance of a tree is unacceptable, a <br /> 1 "Directional Pruning" is defined as the practice of pruning of a tree <br /> limb so that the growth is redirected to the subordinate branches of the <br /> parent limb. The subordinate branches must be at least 1/3 the diameter of <br /> the parent limb. <br /> 2 "Round Over Pruning" is defined as the practice of pruning limbs of a <br /> tree so that the natural form of the tree is transformed to a rounded crown. <br /> 2 <br />
