A. General.
1. Applicability. The provisions of LUC 20.20.520.A, D, E, G, I, J, K, and L apply to development in the EG-TOD in addition to the provisions contained in this section.
2. Review Required. The Director shall review the proposed landscape development, outdoor storage, retail display, and fencing and may approve a proposed structure, alteration, site development, use, or occupancy only if the requirements of this section are met.
B. Street Frontage Landscape Development Requirements.
1. Purpose/Intent. Landscape development as required by this section is necessary to maintain and protect property values, to enhance the visual appearance of the EG-TOD, to preserve the natural wooded character of the Pacific Northwest, to promote utilization of natural systems, to reduce the impacts of development on the storm drainage system and water resources, to provide a better transition between the various land use districts in the Eastgate Subarea and to enhance the pedestrian environment.
2. Street Trees and Landscaping – Perimeter.
a. Street Tree Species.
i. On the A street on the figure in LUC 20.25P.090.A.3, tulip trees (Liriodendron tulipifera) shall be planted.
ii. On the B streets on the figure in LUC 20.25P.090.A.3 street trees shall be planted. The street tree species may be selected from one of the following: triumph elm – Ulmus “Mortong glossy,” Katsura tree – Katsura japonica, or yellowwood – Cladrastis kentukea.
iii. If the tree species listed above are impracticable to install because of disease or because they are unavailable, the Director may approve a comparable substitute species during the Design Review process.
b. Installation. Street trees, at least 2.5 inches in caliper or as approved by the Director, shall be planted at least 3 feet from the face of the street curb, and spaced a maximum of 30 feet apart. A street tree planter area may also include decorative paving and other plant materials, except grass that requires mowing. The use of planter strips for stormwater treatment is encouraged. Installation shall be in accordance with the Parks and Community Services Department Environmental Best Management Practices and Design Standards, as now or hereafter amended.
