Notes for Table 26
Prohibited trees shall also include any that appear on lists of prohibited or invasive plants published by the Ohio Department of Natural Resources, the Ohio Department of Agriculture, or the Ohio Invasive Plant Council.
Number of varieties per street As a rule, streets are more attractive when they contain only one kind of tree. In new developments where an entire street is to be planted it is suggested that the property owners agree on a single variety. Although the planting along one street may be of a single variety, any one community should have a dozen or more kinds. The use of several varieties adds interest to the street-tree plantings of the City and insures against the loss of all trees in case of an epidemic disease striking any one species. The International Society of Arboriculture's "Diversification Formula" will be used as a guideline to prevent overplanting of a single tree species or family. This formula states that, out of the total tree planting, no more than ten percent (10%) should be from one family, and no more than five percent (5%) should be of one species. Sub-dividers or developers are requested to consult with the Community Development Department for a list of the current recommended street trees.
