6) Large-scale, deciduous, canopy trees are preferred for street tree plantings 7) Select tree species whose canopies do not encroach into pedestrian headroom or into tall curbside vehicles such as buses. 8) Preserve existing mature trees through flexible street designs, where possible. 9) Encourage agreements with private develop- ers and landowners to plant and maintain trees and other right-of-way plantings. 10) Ensure proper sight distance and other safety considerations in designing and landscaping planting strips. Maintenance of street trees within planting strips and medians should be ensured to avoid reduction of sight distance. Certain trees with small trunk diameters can be brought forward, especially in conjunction with the use of curb extensions. 11) Consider the potential for utilizing planting strips and medians for stormwater treatment purposes. 12) The width of a planting strip between curb and sidewalk should be based on the figures in Table 1. The minimum planting strip widths shown in Table 1 shall be regarded as strongly preferred. Total width will be determined by available (or obtainable) right-of-way, other design features, and site-specific constraints. 13) Generally, street trees shall be spaced at intervals between 10 and 50', depending on the species. The average spacing of street trees is 30' 14) Trees at the ends of medians should be maintained with a high canopy to maintain sight distance and permit space for traffic control devices on the median nose. Median tree planting should be extended to the intersection if median widths permits and the median is not required for traffic control devices. .1 Routine tree maintenance is necessary to ensure healthy street trees 15) Along Minor Arterial, Major Collector and Neighborhood Collector streets, planting strips and parking lanes may be constructed within the same area, as depicted in Figure 4. 16) Street trees should be planted a minimum of 35' from the midpoint of the tangent of the curb radius at any intersection.
