Removing any live branches, which interfere with the tree's structural strength and healthful <br />development, will include the following: <br />- Limbs of weak structure or otherwise hazardous. <br />SAFETY TREE PRUNING SPECIFICATIONS - Continued . <br />- Selective removal of limbs obstructing buildings or other structures or traffic signs. <br />Generally, limbs closer than five (5) feet to a building or other structure should be <br />removed unless doing so would severely damage a tree. <br />- Clear trees of sprout or sucker growth to a minimum height of eight (8) feet above ground <br />level. Exceptions are allowed for young trees, which would be irreparably damaged by <br />such pruning action. <br />1.07 POWER LINE CLEARANCE (PLC) PRUNING SPECIFICATIONS <br />When trees are in the proximity of overhead energized lines and equipment, reliability of service, <br />safety, and governmental standards require a reasonable amount of tree pruning to avoid <br />conductor contacts and grounding of circuits through the trees. Power line clearance pruning, <br />therefore, shall consist of the removal of tree branches for proper electric line clearance in order <br />to minimize the likelihood of power outages and improve safety. <br />Specifically, trees shall be pruned in such a manner as to: <br />a. Clear all branches and foliage within ten (10) feet of primary electrical lines. <br />b. Clear all branches that interfere with secondary electric lines within three (3) to five (5) feet. <br />c. Protect current tree health, condition and symmetry using Dr. Alex Shigo's book, Pruning <br />Trees Near Electric Utility Lines as a guide. <br />During the tree pruning process, all safe minimum working distances for energized conductors <br />shall be observed. These clearances are defined under ANSI Z133.1-1994. Current ANSI <br />specifications will supersede these requirements when they take effect. Any contact with <br />energized lines shall be promptly reported to an authorized SAPRF representative. <br />Access to backyards must be closely coordinated with the property owner, whenever feasible. <br />Spikes may be used for PLC pruning on palms or other trees only when needed for proper safety <br />reasons. <br />1.08 PALM PRUNING SPECIFICATIONS <br />Palm pruning shall consist of the pruning of the following palms (Syagrus romanzoffianum <br />(queen palm), Archontophoenix cunninghamiana (king palm), Phoenix Canariensis (Canary <br />Island date palm), Phoenix Dactylifera (date palm), Washingtonia filifera (California fan palm); <br />and Washingtonia Robusta (Mexican fan palm) per these specifications. <br />25H-45 <br />
