Fire-hazard designation & local ordinance

FHSZ: Very High (point-check basis)

Lake Arrowhead is designated Very High Fire Hazard Severity Zone, confirmed via a direct point-in-polygon query against CAL FIRE's official hazard-zone data. This is a point-check basis; state that plainly rather than presenting it as a full community survey, since this rests on point verification rather than a published map image reviewed for the whole community.
