In terms of insurable damages, costliest disaster in Canadian history at
C$2.25 billion.
But how accurate is the data being used to underwrite this exposure?
Beware of false knowledge; it is more dangerous than ignorance.
Do insurers understand floodplain mapping well enough to underwrite
the risk due to flooding

No Don’t Know

The Federal Public Safety Department acknowledged the issue and ordered a new study to survey flood mapping in six countries, including the U.S.
Floodplain map boundaries are only as accurate as the topographic map
on which they are drawn. Due to the small scale of Survey maps, the flood boundaries
cannot be precisely mapped… Maps do not always represent exact
conditions on the ground.

advantage.
Remember
Return Periods
For Flood Zone boundaries, indicate the chance of flood waters exceeding that level.
For the 100-year flood plain, the highest point of the water has a 1% chance of being exceeded in any year.
Flood Maps
Represent the primary flood risk assessment tool used by municipalities, insurance companies, banks, etc.
They do not evaluate individual properties and are very broad-based.
The 100-year flood plain is 33 meters, so everything below the line is Zone A.
All houses look the same on a flood map. Is the exposure the same?

Geocoding
Assigns geographic coordinates to street addresses. Hazard mapping using geocoding technology
highlights areas that are vulnerable to a particular hazard, allowing the industry to better determine if a
specific location is subject to natural hazards.
Rooftop Resolution Inputting an address provides the latitude/longitude coordinates of the center of the parcel.
Inputting an address provides the latitude/longitude coordinates of the street in front of where the building is inferred to be.

There is a 268-meter difference between the mapped point and where water actually started entering the facility.
If you were underwriting this risk, would “close enough” be good enough?
Underwriting using only standard flood maps
misses half the properties at risk.
About 30% of multi-claim properties located in flood zones are considered to be moderate or minimal risk.
Don’t be fooled.
Be vigilant about examining flood exposure,
risk by risk. Use all tools and technology available and understand their limitations.
Analyze elevation and topographical features that surround a risk.
To avoid adverse selection, uncover as much information as possible. And know when to investigate further.
Remember the old saying,
Close in flood underwriting puts you at great risk.
“Close only counts in horseshoes and hand grenades.”
