Topanga FAQ
Is my property in a Fire Hazard Severity Zone?
Check the LACoFD Ready Set Go map by address. Most hillside unincorporated areas — Topanga, Altadena, Acton, Agua Dulce, Malibu hills — are mapped Very High. Inland flatland parcels typically are not.
Who clears vegetation along the road frontage?
Owners are responsible for vegetation on their parcel, including out to the road shoulder where the parcel reaches. LA County Public Works clears the paved travel lanes and county-maintained right-of-way only.
Can I appeal a brush clearance notice?
Yes. File a written appeal to LACoFD Forestry within 15 days of the notice. Inspectors can reinspect, adjust requirements for native landscaping plans, or grant short extensions for documented hardship.
