A note on these flood-and-natural-hazard guides: These articles provide general, educational information about California flood hazard, flood insurance, landslides, earth movement, soil conditions,and coastal risks for buyers. They are not an insurance policy, a quote, a binder, a coverage determination, a flood determination, an elevation certificate, an inspection, a survey, a geological or geotechnical report, an engineering evaluation, or a guarantee that any property is safe, insurable, or free from flooding, sliding, settling, erosion, or other damage. Flood mapsand other hazard maps describe identified conditions or regulatory zones but do not predict whether a particular property will suffer damage. Professional roles are separate:a real estate professional is not a geologist, engineer, surveyor, insurer, floodplain administrator, or inspector,and Property DNA is only one supporting research service, never a substitute for official flood maps, Natural Hazard Disclosures, insurance quotes, elevation certificates, inspections, surveys, geological or geotechnical investigations, engineering evaluations, public records, or professional advice. Time-sensitive products, eligibility rules, deductibles, limits, waiting periods,maps,and regulations must be reviewed against current official sources at publication time. For a specific property, consult current FEMA, California,and local maps,and resources,and direct underwritingand coverage questions to a California-licensed insurance professional,and geological, geotechnical, engineering,and other technical questions to the appropriately licensed professional.
