Temecula Municipal Code Art. I General Provisions

This chapter shall be known as "The City of Temecula Protected Tree Ordinance."

(Ord. 09-05 § 1; Ord. 2024-04, 7/23/2024)

A. This chapter will incorporate the city's Urban Forest Management Plan which sets forth the city's policies and guidelines for planting and maintenance programs for the care and protection of its trees. The Public Works Director shall periodically update and make revisions and amendments to the plan, subject to city council approval. This plan shall include the species, sizes, and locations of street trees to be planted.

B. This chapter will set forth that trees on the street tree master list shall be designated by the director and approved by the city council. The list shall be reviewed periodically by the director and commission and shall be kept on file in the director's office.

C. This chapter is established to recognize oak (Quercus spp.), California Bay Laurel (Umbellularia californica), California Black Walnut (Juglans californica), Toyon (Heteromeles arbutifolia), and California Sycamore (Platanus racemosa) trees as well as other mature trees as significant valuable ecological resources as well as valuable environmental assets of special significance to the community; and to justify special efforts to preserve and protect them from development activity.

D. This chapter will also encourage the application of management techniques to control the pruning, cutting, shaping, removal, and relocation of Protected Trees within the city. The preservation program outlined in this chapter will contribute to the welfare and aesthetics of the community and retain the great historical and environmental value of these trees.

(Ord. 09-05 § 1; Ord. 2024-04, 7/23/2024)
