ATTACHMENT 5: TREE SERVICE SPECIFICATION 1.0 INTRODUCTION Trees and other woody plants respond in specific and predictable ways to pruning and other maintenance practices. Careful study of these responses, has led to pruning practices, which best preserve and enhance the beauty, structural integrity, and functional values of trees. In an effort to promote practices, which encourage the preservation of tree structure and health, the following policies and procedures have been established. These specifications are presented as working guidelines, recognizing that trees are individually unique in form and structure, and that their pruning needs may not always fit strict rules. 2.0 OVERVIEW OF SPECIFICATIONS Any tree work performed in the City of Santa Ana Park and Recreation Facilities (SAPRF) must be done according to the SAPRF specifications. There are different criteria for pruning depending on the purpose for the pruning. 2.1 Complete Prune Specifications are used when circumstances deem the entire tree needs to be fully pruned. 2.2 Complete and Aesthetic Specifications are used when circumstances deem the entire tree needs to be fully pruned and in addition shall be reduced on the perimeter of the tree canopy to provide a formal appearance. Examples of when Complete and Aesthetic pruning may occur are government civic centers, commercial -retail centers, and formal landscapes where uniformity in appearance is required. 2.3 Safety Prune Specifications require less pruning and are used when specific, possibly hazardous (dead/dying) limbs need removal to eliminate all safety concerns. Safety pruning may be recommended in some circumstances instead of a complete prune. Safety pruning specifications are used for "as needed" pruning as outlined above and address only safety concerns. Safety pruning includes only the basic requirements and does not include the fine pruning detail work outlined in a complete prune. 2.4 Power Line Clearance Prune (PLC) Specifications are used for private tree power line clearance work and for street tree (PLC) pruning when the tree is pruned between its periodic complete pruning cycles. 2.5 Palm Pruning Specifications are used when pruning any type of palm. All specifications are based on International Society of Arboriculture, National Arborist Association and American National Standards Institute criteria. This guarantees that SAPRF trees receive the best possible care. 3.0 GENERAL REQUIREMENTS The following requirements shall be used during any pruning work to be performed on SAPRF trees: 3.1 Proper disposal of all tree debris generated.
