Such regulations shall also contain a list of approved species of trees which may be planted on public streets within the city. The existing list as set forth in sections 15-4-12 and 15-4-13 of the preceding tree ordinance is repealed by the ordinance codified in this chapter but is preserved as the initial approved list until such list is altered or modified by regulation passed by the city.
