Tree Condition Condition Ratings Good: trees in Good condition have no significant issues. Fair: trees in Fair condition may have some issues which are likely to improve with time or maintenance (e.g., dead branches that can be removed during pruning, minor trunk wounds that the tree can heal over time). Poor: these trees have more significant issues which are not likely to improve with time or maintenance (e.g., large sections of dead canopy, decay cavities in the stem or roots). Dead: Dead trees show no signs of life.

Size Class Distribution Preponderance of Established Trees Increase planting of young trees to replace older trees as they age

Size Class Distribution and Condition Mature trees have the highest percentage of Poor & Dying trees and may require more budget allocation to maintain as they age Street Trees (ROW)

Maintenance Recommendations Young Tree Training Prioritize training young trees in the 4”-6” in the first few years of the cycle.

KEY FINDINGS Summary • 8,230 trees, 99 stumps, and 2,525 vacant planting sites were inventoried citywide. • Maples are overrepresented (~51% of trees); future maple planting should be limited to uncommon species. • Overall tree condition is Fair–Good and can improve with proactive maintenance. • ROW stocking is 76%, indicating room for additional tree planting. • Inventoried trees provide ~$79,800 annually in ecosystem services. • Large-stature trees provide the greatest benefits and should be prioritized.
