This Appendix C is designed to encourage an imaginative selection of landscape trees. Careful selection will prevent an over-dependence on a few species. This Appendix C will be useful to residents, nurserymen, horticulturists, landscapers, developers and landscape architects.
Along an individual street, uniform street tree plantings are desirable. However, overuse of a few species is inevitable without a conscious effort to vary plant species and families. Deviations from the recommended list are permitted with the approval of the Planning and Zoning Commission.
The list is divided into three size categories: large trees which mature at a height of 50 feet or more (Group A); medium trees which reach a mature height of between 30 and 50 feet (Group B); and small trees which range from ten to 30 feet at maturity (Group C). Tree lawn sizes must accommodate the tree size planted: Group A (greater than seven feet); Group B (four to seven feet); Group C (three to four feet). Use under utility lines is limited to small trees, although medium trees may be planted as close as ten lateral feet to utility lines.
The approximate mature height and diameter of the crown of each tree are given.
Trees are alphabetized by their scientific name with the common name given. Cultivars best suited to central Ohio are also provided. An asterisked entry indicates a tree which is unsuitable for planting within 15 lateral feet of a sidewalk or bike way.
Habit refers to the three dimensional form of the tree. Six general terms describe the characteristic shape of the trees:

The tolerance category presents information from various sources listed in the bibliography. The tree’s relative tolerance to insects, diseases, pollution and soil conditions is signified by either a “Y” meaning yes, it is tolerant; “N” meaning no, it is not tolerant; or “-” meaning no information is available from these sources.
Comments pertain to any other notable characteristic of the tree.
