Davey Resource Group, Inc. Tree Inventory Analysis & Maintenance Strategy Page 18 PRIORITY MAINTENANCE PRIORITY MAINTENANCE NEEDS Addressing Dead and Poor condition trees identified in the inventory (Figures 10 & 11) in a timely manner will mitigate possible unidentified risk, improve public safety, maximize tree benefits, and reduce long-term costs. In general, Extreme and High Risk maintenance activities should be completed first for larger diameter trees that pose the greatest risk. Once these trees are addressed, recommended tree maintenance activities should be completed for small diameter trees. The inventory identified: ● 60 Dead street trees and 41 park trees recommended for removal (Figure 10). These Dead trees recommended for removal ranged in size from 3 to 32 inches DSH . ● 206 Poor condition street trees and 430 park trees recommended for removal (Figure 11). These poor condition trees recommended for removal ranged in size from 1 to >31 inches DSH. Fair, Good, and Excellent condition trees identified in the inventory are categorized as a part of routine maintenance and are discussed in the Routine Pruning section below. PRIORITY MAINTENANCE RECOMMENDATIONS ● Trees with Dead or Poor condition ratings recommended for removal should be removed as soon as reasonably possible and prioritized based on their condition rating and size class. Tree removal is recommended when pruning will not correct the tree’s defects, will not eliminate the risks caused by defects, or when pruning would be cost-prohibitive. Figure 10.
