San Diego County does not have a specific heritage tree ordinance for unincorporated areas. However, exceptionally old or large native trees receive protection under the Resource Protection Ordinance. Significant native vegetation is evaluated during the development review process.
Unlike some California jurisdictions, unincorporated San Diego County does not have a standalone heritage tree ordinance with formal designation and registry. However, significant native vegetation, including large and old native trees, is protected under the Resource Protection Ordinance (RPO). During development review, the County evaluates impacts to native vegetation and may require preservation of significant trees or mitigation for their removal. Native oaks, particularly coast live oaks and Engelmann oaks, receive attention due to their ecological importance. The County's biological guidelines consider tree age, size, and species rarity. Community groups in some unincorporated areas may advocate for protection of locally significant trees.
Removal of significant native trees during development without proper mitigation may result in enforcement actions, required replacement planting, and project delays.
