South Broad Street Corridor Area Plan – PC Hearing Draft February 2012 4.3 STREET TREES AND LANDSCAPING The future growth area shall be landscaped with a palette of street trees and landscaping appropriate in scale and species for each of the differing street types in order to establish the hierarchy of streets and provide a cohesive theme for the area. Street trees should be planted on both sides of streets and generally be spaced no more than forty (40) feet apart. Figure 4.4 Street tree placement Species. Each street should have one dominant species of street tree for in-sidewalk planters or parkways, with alternate tree types for any in-street parking space trees (bulb-outs) and planted medians. Largecanopy, deep-root street trees should be used on all streets, as listed in the City’s Tree Regulations. Tree species should be selected to provide a consistent range in tree form, height, color, and texture, and to provide a canopy over sidewalk and street areas. Preferred street tree species for Entry, Village, and Service Streets are: London Plane (Platanus acerifolia), Chinese Elm (Ulmus paviflolia), Jacaranda (Jacaranda mimosifolia), Chinese Pistache (Pistacia chinensis), and Red Maple (Acer rubrum). Alternative species from the approved City list may be approved by the Architectural Review Commission. Tree Grates. Sidewalks shall be City standard integral curb-gutter with a minimum width of ten (10) feet. Generously sized tree grates should be placed around street trees, off-set in right-of-way, with the edge of the grating spaced eighteen (18) inches from the back of the curb, as shown in Figure 4.5. Tree grates should occur along sidewalks and in public plazas where a continuous walking surface is needed. A standard tree grate size, shape and finish shall be used. Size shall be 48 inches by 72 inches, with longest dimension parallel to the street. The design is shown in Figure 4.5, Neenah Foundry Model R-811, Model R- 8815-1, or equal.
