16) Regarding the SVT's, other than trees as noted below, plant materials located within existing and future sight visibility triangles shall be limited to ground cover or low-growing vegetation of a species that will not grow higher than thirty inches. Trees may be located within existing and future sight visibility triangles only if clear of leaves and branches to a height of at least six feet above grade upon installation, and at all times thereafter. The trunk caliper of any species selected may not exceed twelve inches in diameter at maturity. Trees with multiple trunks are not allowed. Trees may not be planted in a line that could result in a solid wall effect as viewed from the motorist's perspective. The number and location of trees within existing and future sight visibility triangles may be restricted or modified by the City of Tucson Inspectors in order to preserve visibility.
