18J.100.080 Planting Design.
A. The purpose of this Section is to encourage the use of native vegetation as plantings. Wherever possible planting designs should emphasize the preservation and enhancement of existing, native vegetation. The use of native and drought tolerant plantings is also encouraged in all projects. (Refer to PCC 18J.15.040 for other landscaping and buffer requirements and guidelines.)
1. Design Objective – Planting Design. Design plantings to incorporate native plant species. Drought tolerant plantings are allowable substitutes for native species to the extent that invasive species are not introduced into the area. The following planting design standards are intended to supplement the Landscape Standards, PCC 18J.15.040, by providing landscape criteria for projects in Alderton-McMillin.
a. Standards.
(1) At least 50 percent of all trees, shrubs, and/or ground covers shall be native plant species.
(2) Lines of street tree plantings along street frontages are prohibited. Tree plantings shall be grouped or clustered in natural, rather than formal arrangements. No more than three trees shall be planted in a row without an interruption of at least twice the distance of the tree spacing of that row.
(3) Rural Industrial Center properties on the exterior boundary shall install a L3 landscape buffer where abutting a non-industrial use. (Refer to PCC 18J.15.040 H.3.)
(4) The use of fencing shall not be permitted for perimeter screening requirements in the Rural 10 zone.
