Shade trees are defined as having a height of over forty (40) feet at maturity; ornamental trees are defined as having a height of less than forty (40) feet at maturity.
- A variety of compatible species should be included in the planting plan for a specific site or development. The selecting of tree species shall be reviewed and approved by the Department of Parks and Parkways with particular regard for site-appropriate species.
