<br /> <br /> <br /> <br /> <br /> <br /> 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 /> <br /> a. Clear all branches and foliage within ten (10) feet of primary electrical lines. <br /> <br /> b. Clear all branches that interfere with secondary electric lines within three (3) to five <br /> (5) feet. <br /> <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 /> <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 /> <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 /> <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 /> <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 /> <br /> 251-54 <br />
