   (B)   Small Trees are appropriate in street locations where due to space limitations larger trees cannot be properly utilized without creating space 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 tend to be more ornamental than their larger counterparts and can create an added aesthetic dimension to the streetscape.
