What species are approved for replacement trees?
Replacement species must be appropriate for Costa Mesa's climate and approved by the Planning Division. Drought-tolerant and native species such as coast live oak and California sycamore are encouraged. The Public Works Department maintains a street tree list for public right-of-way replacements.

Midway City FAQ
How many replacement trees do I need to plant in Orange County?
It depends on the tree classification. Specimen Trees require 3:1 replacement by aggregate trunk diameter. Heritage Trees require 5:1. If on-site replanting is insufficient, mitigation fees apply.
Can I pay a fee instead of planting replacement trees?
Only if on-site replanting cannot meet the required ratio. The county prefers on-site preservation and replanting. Mitigation fees go to the county's urban canopy program when on-site replacement is not feasible.
