Pomona, CA Tree Protection: Protected Tree Species (2026)

Sec. 5 feet above mean natural grade, on public or private property, that sit outside designated historic districts/landmarks and are not already listed as Specimen Trees. No one may trim, prune, cut, relocate, or remove a covered Oak without a Major or Minor Oak Tree Permit (OTP). Trimming on private property needs only a Minor OTP, decided administratively by the Planning Manager with City Arborist review; relocating or removing an Oak, on private or City property alike, needs a Major OTP, decided by the Planning Commission at a public hearing noticed at least 10 days ahead in a daily newspaper and by mail to owners within 400 feet.

Major OTP applications must state the reason for relocation/removal, tree size and species, a site plan, photos, the proposed method, and, for diseased or dying trees, City Arborist verification. Approval requires findings on erosion control, that the tree genuinely impedes a permitted use, utility or street interference, or irremediable disease/fall risk. Exemptions cover City Arborist-initiated trimming on City property, dead-wood removal, nursery/tree-farm stock, railroad right-of-way, Caltrans or LA County Flood Control District land, and Arborist-confirmed hazard trees. Permits are valid 30 calendar days, with one fee-free 30-day extension; the permittee must request a final inspection within 72 hours of completed work.

Removed Oaks must be replaced 1:1, with a minimum 24-inch box tree on residential property or a 36-inch box tree on institutional, commercial, or industrial property, planted on-site where feasible or paid to the City at ISA-determined value for planting elsewhere in the City.
