1 LANSCAP TR LIST The following list of trees was compiled to aid lscape architects designers in selections for parking lot shading, street frontage /or visual screening. Tree selection should be based on adaptability to site conditions. Individual constraints characteristics are shown in columns on the attached list to help choose an appropriate tree: width: Recommended minimum planter width : Approximate tree height near maturity Growth: Growth rate Roots: Root growth depth Soil: Suggested soil type Flowers/: Significant flowers /or fruit / : = deciduous or = evergreen : Characteristics such as fall color, diseases, other miscellaneous information The species listed are not recommended for all situations; other species may be appropriate for a particular use. Consultation with a lscape architect, certified arborist, /or nursery person is urged before any selections are made. Professional guidance is recommended to assure that the optimal design is achieved to meet the goals of each project. Proper planting procedures, adequate space, soil, water requirements, applicable County codes ordinances, maintenance programs should be ascertained at the start of the lscape project. It is important to note that proper planting procedures may include digging past any existing hardpan layer to assure deep rooting proper growth. NOT: Symbols have been placed in front of certain species to indicate that particular tree s potential use for shade or screening purposes. An asterisk (*) indicates that the tree has characteristics appropriate for use as a screen tree. A plus mark (+) denotes that the tree has characteristics to provide good shade.
