Flood availability depends on the property
Insurers use their own hazard models, data and public flood information to decide whether overland flood coverage is available and at what terms. A municipal or provincial flood map is therefore useful risk evidence, but it does not itself guarantee an insurer will offer coverage.
Optional flood coverage should be compared by wording, not name
Policies can differ in the water sources covered, exclusions, limits, deductibles and treatment of basement contents. Homeowners should distinguish overland flood from sewer backup and from ordinary sudden escape of water because those causes of loss can be handled under different sections of the policy.
DFA is not a replacement for available insurance
British Columbia's Disaster Financial Assistance program supports certain sudden, unexpected and uninsurable essential losses after an eligible disaster. The Province states that assistance is not available for losses where insurance was reasonably and readily available, so relying on potential government assistance instead of available coverage can create a serious protection gap.
Flood maps help explain risk, but insurers make their own availability decisions
The Province says insurers use their own tools, data and public flood information when deciding where overland flood insurance is available. New public floodplain mapping can improve risk information without guaranteeing that a specific property will receive coverage.
