If injury should occur to any tree during construction, it should be evaluated as soon <br />as possible by the Consulting Arborist so that appropriate treatments can be applied. <br />3. Prior to excavation for the storm drain line, tree #448 may require root pruning outside <br />the TREE PROTECTION ZONE by cutting all roots cleanly to the depth of the excavation. <br />Roots shall be cut by manually digging a trench and cutting exposed roots with a <br />sharp saw or other approved root pruning equipment. The Consulting Arborist will <br />identify where root pruning is required. <br />4. No excess soil, chemicals, debris, equipment or other materials shall be dumped or <br />Stored Within the TREE PROTECTION ZONE. <br />5. Any additional tree pruning needed for clearance during construction or around new <br />structures must be performed by a Certified Arborist and not by construction <br />personnel. <br />Maintenance of impacted trees <br />Tree preserved at the Trinity Lutheran Church site will experience a physical environment <br />different from that pre-development. As a result, tree health and structural stability should be <br />monitored. Occasional pruning, fertilization, mulch, pest management, replanting and <br />irrigation may be required. In addition, provisions for monitoring both tree health and <br />structural stability following construction must be made a priority. As trees age, the likelihood <br />of failure of branches or entire trees increases. Therefore, annual inspection for hazard <br />potential is recommended. <br />Hor`tS,~cience, Inc. <br />~W ~ ~ <br />John Leffingwell <br />Certified Arborist WE-3966A <br />Registered Consulting Arborist #442 <br />
