DESCRIPTION

Property insurance underwriters urgently need to ask themselves if they understand the shortcomings of standard floodplain mapping well enough to continue covering flood risk. Read the full blog post here: http://www.genre.com/knowledge/blog/what-you-dont-know-about-flood-can-hurt-you.html

But how accurate is the data being used to underwritethisexposure? Beware of false knowledge; it is more dangerous than ignorance. 16. Do insurers understand floodplain mapping well enough to underwrite the risk due to flooding 17. Northern Canada Central Canada Eastern CanadaWestern Canada 2013 Survey of Canadas Largest Property/Casualty Companies No Dont Know Yes No Response 18. The FederalPublic Safety Department acknowledged the issue and ordered a new study to surveyflood mapping in six countries, includingthe 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. 19. How do we improve understanding of the Flood Risk 20. Increased understanding of: 21. Return Periods Increased understanding of: 22. Flood Maps and Mapping Errors Return Periods Increased understanding of: 23. Flood Maps and Mapping Errors Geocoding and Geocoding Errors Return Periods Increased understanding of: 24. Transforming information into knowledge is a competitive advantage. Remember 25. 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. 26. 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. 27. 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? 100-Year Flood Elevation 31 m. 34 m. 32 m. 33 m. 30 m. 36 m. 39 m. 33 m. 28. Not all locations in the 100-year zone are the same. Dont rate them that way. 64 meters elevation 67 meters elevation 67.5 meters elevation 100 meters elevation 29. 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. 30. 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. Street Level 31.

Using the Latest Mapping Technology Imagery 2014 Google, Map data 2014 Google There is a 268-meter difference between the mapped point and where water actually started entering the facility. If you were underwritingthis risk, would closeenough be good enough? 34. Underwriting using only standard flood maps misses half the properties at risk. 35. About 30% of multi-claim properties located in flood zones are considered to be moderate or minimal risk. Dontbefooled. 36. Be vigilant about examining flood exposure, risk by risk. Use all tools and technology available and understand their limitations. 37. Analyze elevation and topographical features that surround a risk. To avoid adverse selection, uncover as much informationas possible. And know whento investigate further. 38. Remember the old saying, Close in flood underwriting puts you at great risk.
