Para 4.13.8 Street Tree Landscape
Xeriscape requests for the parkway areas will be reviewed on a case-by-case basis. All submittals shall use a high density of low growing Xeriscape type plants and boulders in conjunction with the proposed landscape material. Unplanted rock or wood mulch areas are not permitted in the parkway. Plants that are 24-inch or lower are preferred where vehicle or pedestrian visibility may be impaired. Street trees located in a Xeriscape parkway using rock mulch should be encircled with a small ring of wood mulch as defined in paragraph 2.13.9(e). Boulders are allowed in addition to some plants, and limited to a maximum size of 24 inches x 24 inches x 24 inches.
