No more than twenty five (25) percent of the live wood may be removed from the crown <br />of any tree, without approval of an authorized SAPRF representative, excepting live oaks, <br />which are limited to no more than ten (10) percent. Resulting in keeping as much of the <br />crown of the tree as possible. <br />j. Any extraneous metal, wire, rubber or other material (i.e. stakes, ties) interfering with tree <br />growth shall be removed immediately. <br />k. Any defective or weakened trees shall be reported to an authorized SAPRF representative. <br />Specifically, any structural weakness of a tree, decayed trunk or branches, shall be <br />reported in writing, noting the location of the tree by street address and a description of the <br />hazard found in the tree. <br />The use of climbing spurs or spike shoes in the act of pruning trees is prohibited, except <br />palms that are more than sixty-five (65) feet in height. <br />in. Beneficial animal, bird nests, nesting cavities or other wildlife habitat shall be preserved <br />and protected whenever feasible, unless doing so would create a hazard. <br />1.05 COMPLETE TREE PRUNING SPECIFICATIONS <br />Complete tree pruning shall consist of the total removal of dead or living branches that may <br />threaten the future health, strength and attractiveness of trees. Specifically, trees shall be <br />pruned in such a manner as to: <br />a. Prevent branch and foliage interference with requirements of safe public passage. Over <br />street clearance shall be kept to a minimum of sixteen (16) feet above the paved surface of <br />the street, fifteen (15) feet above the curb and eight (8) feet above the surface of a public <br />sidewalk or pedestrian way. Exceptions are allowed for young trees, which would be <br />irreparably damaged by such pruning action. <br />b. Remove all dead and dying branches and branch stubs that are one half (1/2) inch diameter <br />or larger. <br />Remove all broken or loose branches. <br />d. Remove any live branches, which interfere with the tree's structural strength, and healthful <br />development, which will include the following: <br />1) Branches, which rub and abrade a more important branch. <br />2) Branches of weak structure, which are not important to the framework of the tree. <br />3) Branches, which if allowed to grow, would wedge apart the junction of more <br />important branches. <br />4) Branches forming multiple leaders in a single leader type tree. <br />5) Branches near the end of a limb, which will produce more weight or offer more <br />resistance to wind than the limbs are likely to support. <br />48 <br />19C-51
