Simi Valley requires permits to remove protected trees including native oaks and designated significant trees. The application process requires an arborist report and the city typically mandates replacement planting or in-lieu fees.
The Simi Valley tree preservation ordinance requires a tree removal permit from the Community Development Department for all protected trees. Protected trees include native oaks (coast live oak, valley oak, scrub oak) with trunk diameters of 5 inches or more at 4.5 feet above grade, and any tree designated by the city as a significant or heritage tree. The permit application requires a certified arborist's report documenting the tree's species, size, health, and justification for removal. The review process typically takes 4 to 6 weeks and may require a public hearing for large or prominent trees. Approved removals generally require replacement planting at ratios of 2:1 to 3:1 with same-species trees of specified minimum container size, or payment of an in-lieu mitigation fee.
Removing a protected tree without a permit carries fines from $1,000 to $10,000 per tree depending on species and size. The violator must also plant replacement trees at enhanced ratios (up to 5:1) and pay restoration costs. Criminal prosecution may be pursued for willful violations. Enforcement is handled by Code Enforcement at (805) 583-6238.
