APPENDIX <br />ATTACHMENT S: TRIBE SERVICE SPECIFICATION <br />1.0 INTRODUCTION <br />Trees and other woody plants respond in specific and predictable ways to pruning and other <br />maintenance practices. Careful study of these responses, has led to pruning practices, which best <br />preserve and enhance the beauty, structural integrity, and functional values of trees. <br />In an effort to promote practices, which encourage the preservation of tree structure and health, <br />the following policies and procedures have been established. These specifications are presented <br />as working guidelines, recognizing that trees are individually unique in form and structure, and <br />that their pruning needs may not always fit strict rules. <br />2.0 OVERVIEW OF SPECIFICATIONS <br />Any tree work performed in the City of Santa Ana Park and Recreation Facilities (SAPRF) must <br />be done according to the SAPRF specifications. There are different criteria for pruning <br />depending on the purpose for the pruning. <br />2.1 Complete Prune Specifications are used when circumstances deem the entire tree needs to <br />be fully pruned. <br />2.2 Complete and Aesthetic Specifications are used when circumstances deem the entire tree <br />needs to be fully pruned and in addition shall be reduced on the perimeter of the tree <br />canopy to provide a formal appearance. Examples of when. Complete and Aesthetic <br />pruning may occur are government civic centers, commercial -retail centers, and formal <br />landscapes where uniformity in appearance is required. <br />2.3 Safety Prune Specifications require less pruning and are used when specific, possibly <br />hazardous (dead/dying) limbs need removal to eliminate all safety concerns. Safety <br />pruning may be recommcnded in some circumstances instead of a complete prune. <br />Safety pruning specifications are used for "as needed" pruning as outlined above and <br />address only safety concerns. Safety pruning includes only the basic requirements and <br />does not include the fine pruning detail work outlined in a complete prune. <br />2.4 Power Lino Clearance Prune (PLC) Specifications are used for private tree power line <br />clearance work and for street tree (.PLC) pruning when the tree is pruned between its <br />periodic complete pruning cycles. <br />2.5 Palm Pruning Specifications are used when pruning any type of palin. <br />All specifications are based on International Society of Arboriculture, National Arborist <br />Association and American National Standards institute criteria. This guarantees that SAPRF <br />trees receive the best possible care. <br />3.0 GENERAL REQUIREMENTS <br />The following requirements shall be used during any pruning work to be performed on SAPRF <br />trees: <br />City of Santa Ana RFP 16-126 <br />rage 4g <br />
