Fire-hazard designation & local ordinance
FHSZ: Moderate, High, and Very High all present
Rancho Santa Margarita has Moderate, High, and Very High Fire Hazard Severity Zones all present within city limits. This genuinely varies by sub-area; no single tier applies uniformly across the city, so it should not be characterized by one blanket designation.
The city's 2025 FHSZ map page documents the current designations, and the city's own LRA FHSZ document corroborates the mixed-tier picture.
