Street Tree Planting Guidelines

• Tree Diversity will be emphasized (i.e. no more than 10 % of same tree type).
• Ash species will not be costshared by City for planting as street trees due to potential Emerald Ash Borer infestation and will not be allowed to be planted on city rightofways due to existing ash street tree population being greater than 25%.
• Large type trees and small type trees will not be planted on same street because of variance in height, form and growing space requirements. Only exception is that small shade tolerant understory type trees (redbud, serviceberry) can be planted beneath large overstory shade trees, provided there is adequate room to accommodate the mature growth of understory tree.
