3. Trees Prohibited from Use as Street Trees
All trees of the willow family:
Salicaceae			Some are beautiful trees in proper situation; however, all are rank feeders, requiring large amounts of water & space; trees are fast-growing, short-lived, easily broken, clog sewers, many have suckering root, highly subject to disease and insects
Genus Salix & Populus
Willow Cottonwood Poplar
Russian Olive		*Elaeagnus angustifolia*	Useful in proper location, but in a street tree situation the material gets straggly with age, drops leaves, twigs and fruit
All Fruit Trees (except Crabapple)			Trees drop fruits onto streets and sidewalks creating safety hazard; many are highly subject to insect and disease problem, require special maintenance practices
