3) Clear trees of sprout or sucker growth to a minimum height of eight (8) feet <br />above ground level. Exceptions are allowed for young trees, which would be <br />irreparably damaged by 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 <br />service, safety, and governmental standards require a reasonable amount of tree pruning <br />to avoid conductor contacts and grounding of circuits through the trees. Power line <br />clearance pruning, therefore, shall consist of the removal of tree branches for proper <br />electric line clearance in order to minimize the likelihood of power outages and improve <br />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 <br />(5) feet. <br />c. Protect current tree health, condition and symmetry using Dr. Alex Shigo's book, <br />Pruning Trees Near Electric Utility Lines as a guide. <br />During the tree pruning process, all safe minimum working distances for energized <br />conductors shall be observed. These clearances are defined under ANSI Z133.1-1994. <br />Current ANSI specifications will supersede these requirements when they take effect. <br />Any contact with energized lines shall be promptly reported to an authorized SAPRF <br />representative. <br />Access to backyards must be closely coordinated with the property owner, whenever <br />feasible. Spikes may be used for PLC pruning on palms or other trees only when needed <br />for proper safety reasons. <br />1.08 PALM PRUNING SPECIFICATIONS <br />Palm pruning shall include, but not be limited to, the pruning of the following palms <br />(Syagrus romanzoffianum (queen palm), Archontophoenix cunninghamiana (king palm), <br />Phoenix Canariensis (Canary Island date palm), Phoenix Dactylifera (date palm), <br />Washingtonia filifera (California fan palm); and Washingtonia Robusta (Mexican fan <br />palm) per these specifications. <br />a. The removal of all dead fronds and other dead plant parts from the trunk. All loose <br />frond sheaths shall be removed along the entire length of the palm trunk. <br />b. The removal of all flowers and fruit parts whether dead or alive. <br />c. The use of climbing spurs or spike shoes in the act of pruning trees is prohibited, <br />excepting palms that are more than sixty-five (65) feet in height. <br />d. Canary Island date palm (Phoenix Canariensis) trunks shall be cleaned of any weed <br />species. The immediate area below the green fronds shall be trimmed to a <br />symmetrical (pineapple) appearance. The shape shall not exceed a minimum of <br />forty-eight (48) inches or a maximum of sixty- (60) inches length below the green <br />44 <br />
