Protected Tree Species: Carson vs Santa Monica

How do protected tree species rules compare between Carson, CA and Santa Monica, CA?

Carson has fewer restrictions than Santa Monica.

Carson, CA

Los Angeles County

Some Restrictions

Carson does not maintain a list of 'protected species' (e.g., native oaks, sycamores) in its Municipal Code in the way some Northern California cities do. Carson regulates trees by location (parkway / right-of-way) under Chapter 9 rather than by species. State-level protection applies only to specific listed species under the California Endangered Species Act and CCR Title 14 forestry rules.

Santa Monica, CA

Los Angeles County

Heavy Restrictions

LA County Code Title 22.174 (formerly 22.56.2050) protects native oaks with eight inches or larger trunk diameter at breast height. An Oak Tree Permit from Regional Planning is required before pruning more than 25 percent or removing any protected oak.

Carson FAQ

Does Carson protect native coast live oaks like LA County does?

No. Los Angeles County's Oak Tree Ordinance (Title 22 §22.174) applies in unincorporated LA County and does not apply within Carson city limits. Carson's own code protects only parkway trees under Chapter 9. A native oak entirely on private Carson property is not covered by a city-wide species ordinance, but may still be protected through state CESA if the species is listed.

Are there any tree species banned from planting in Carson?

Carson uses a positive list — the Authorized List of Carson Trees (Exhibit A to Chapter 9). Anything not on the list cannot be planted in the parkway. The City Manager designates which authorized species are planted in any given parkway; planting a non-conforming species in the right-of-way without a permit can result in the tree being removed by the City.

Santa Monica FAQ

Does the oak ordinance apply to dead trees?

A confirmed dead oak generally does not require a permit, but a certified arborist report and Regional Planning concurrence are required first. Hazardous live oaks may qualify for an emergency permit with reduced fees and expedited review.

What if construction must encroach on a protected oak?

Submit an Oak Tree Permit application with arborist-prepared protection plan, root-zone fencing, and impact analysis. Regional Planning may require redesign, deep watering, or replacement plantings before approving encroachment.
