The city does not require a specific number of a specific size andtype of tree to be provided. Instead, the city requires that a certain number of "treefactors" be provided.

Tree size and conversion rates are listed in the Material Standards section.The intent of using tree factors instead of a specific number of specific trees is to allowthe design flexibility.One tree factor shall be required for every 700 square feet of the Street YardGreenspace. A bonus of one percent of the tree factor shall be granted for every threepercent that the area of the street yard exceeds the minimum area acceptable (M x W).The tree factors used to meet this requirement shall be located within the greenspacearea.Example.
