Specifications include, but are not limited to: The Consultant shall inventory various trees located on the public rights-of-way and other public properties as designated by the City. At a minimum, the information collected for each tree shall include: 1. Location - Identify the location of each tree. All street tree locations should be organized by sequential tree site number and road name, block side, area and GPS coordinates. An X and Y location will be generated for each site. 2. Species - Trees are identified by genus and species using both botanical and common names and by cultivars where appropriate. 3. Trunk Diameter - Diameter is measured to the nearest inch in one-inch increments at 4-1/2 feet above the ground, or diameter-breast-height (DBH). Record as a single value, ranges will not be accepted. 4. Functional and Structural Condition - The general condition of each tree is rated according to the following categories adapted from the International Society of Arboriculture’s rating system: • Good • Fair • Poor • Dead • Not Applicable • RATE BASE, STEM AND CANOPY 5. Primary Maintenance Need - The following primary maintenance needs will be determined based on ANSI A300 standard specifications: • Train - A pruning recommendation to improve structure, health, and vigor of a young tree. This will correct structural flaws and make tree more aesthetically pleasing. • Thin - A selective removal of live branches to evenly distribute crown weight and to reduce density. The intention of this pruning is to reduce wind resistance, reduce snow and ice loads, and to increase light penetration. • Raise - The removal of lower branches from the crown to eliminate obstructions or clearance issues. The majority of these cuts will be made at the tree trunk. • Clean - A crown cleaning to remove dead, diseased, damaged, poorly attached, or crossing branches to increase longevity and reduce failures. • Remove - The complete removal of a dead or dying tree that has no potential of improving with maintenance. • Stump Removal - This category indicates a stump that should be removed. Any stump in the public right-of-way or park over 2 inches from ground level to be specified for removal. • Plant - A site well suited for a new tree planting and the recommended species size at maturity 6. Maintenance Priority. All of the primary maintenance needs will be prioritized as to the severity of the recommendation. The following descriptions will be used. • Young - This describes a young or newly planted tree that will probably not need immediate attention to increase longevity. • Routine - This maintenance recommendation should be part of a cyclical pruning program.
