Medium-sized trees are better suited for planting on normal village parkways than their larger counterparts. Large trees require more living space, and for this reason it is recommended that they be planted on the private side of the sidewalk whenever possible. The overall objective of proper tree selection is to select the right tree for the right location in order that one may benefit from the tree without being subject to future maintenance liabilities or hazards.

Small trees are appropriate in parkway locations where due to space limitations larger trees cannot be properly utilized without creating spacing conflicts with existing trees. Height limitations imposed by overhead utilities also necessitate the use of appropriate small trees in order to avoid line conflicts and the necessity of excessive utility trimming that results in disfigured trees. On the whole, small trees which tend to be more ornamental than their larger counterparts can create an added aesthetic dimension to the streetscape.

*Selected cultivars or varieties of suitable form and resistant to scab disease (see Appendix A for listing of recommended crabs for local use).

Table II

The following is a listing of trees more or less common to our area that are not suitable as street or parkway trees. Their lack of suitability is based upon undesirable growth habits, fruiting habits, form, susceptibility to serious diseases, propensity to storm damage, and a host of other limitations too numerous to mention. The limitations listed for each tree or species group are not all-inclusive and mention only the more serious problems encountered locally. In essence, there are far too many superior street or parkway trees listed in Table I to warrant the use of any of the trees listed in Table II except under special circumstances.

Though many of the trees listed in Table II are presently growing on our parkways as a result of previously unrestricted plantings, they do constitute a maintenance liability to the village and as such should be replaced on removal with species listed in Table I.

 

Scientific Name	Common Name	Problem or Limitation
Abies sp.	Fir	Form — visibility hazard
Acer negundo	Boxelder	Fast growing, weak wooded
Acer Platenoides	Norway maple	Local problem, verticillium w

Ailanthus altissima	Tree of Heaven	Weak wooded, aggressive

Diospiros	Persimmon	Littering fruit
Gleditsia sp.	Honeylocust	Serious disease/insect problem
Juglans sp.	Walnut	Littering fruit
Juniperus sp.	Juniper	Form — visibility hazard

      (1)   Other tree species or their varieties not listed in the foregoing Table I may be planted on village-owned property, but only desirable trees of good appearance, beauty and adaptability that are generally free from injurious inset, diseases or other limitations may be planted.

      (2)   Where certain planting sites have been assigned a particular species or variety, only the designated species or variety shall be planted on such sites, unless the plan is reviewed by the Village Forester with the advice and assistance of the Tree Committee.

      (3)   The Tree Committee, in conjunction with the Village Forester, shall review, al least once every two years, the species, cultivars and varieties listed on Table I to determine whether any should be removed or whether certain new species, cultivars or varieties of proven adaptability and value should be added; and the Tree Committee shall similarly review the trees listed in Table II to determine whether any should be removed or whether certain new species, cultivars or varieties should be added thereto.
