The power to designate the kind and variety of shrubbery, palms or trees to be planted shall be vested in the City Planning Commission. The owners of property fronting on such streets may petition or request the City Planning Commission that the shrubbery, palms or trees to be designated and planted shall be of a certain kind or variety. Such petition or request shall be merely advisory to the action of the City Planning Commission. Upon a written appeal to the City Council, signed by the owners of not less than thirty percent of the property frontage on specific streets where the City Planning Commission has planted or proposes to plant trees or shrubbery of a certain variety, protesting against the planting of such variety of trees or shrubbery or requiring the planting of none or of other varieties of trees or shrubbery, the City Council shall take the matter under advisement and determine what variety of trees or shrubbery, if any, shall be planted. Nothing in this section shall be construed to prevent or prohibit the planting in and upon the streets of the City of shrubbery, palms or trees of the kind or variety designated by the City Planning Commission or to prevent or prohibit the caring for of any shrubbery, palms, or trees upon the streets of the City. (Code 1962, § 35-35)
