Effectiveness of Building Codes and Storms

We have found that for different samples of our loss data, the benefit-cost ratios range from a low of 2.67 to a high of 7.93. In other words, comparing the increased construction cost to the expected reduction in windstorm damage across the life of the home shows anywhere from $2 to $8 in expected damage reduction—the benefit—for every dollar of increased cost.

2am While the risk of tornadoes may continue during the night, this will have to end my coverage.  Note the risk of tornadoes farther east later today.  1:35am Wednesday: Tornado watch will likely be issued for the outlined area, including the Kansas City Metro. Make sure you have a way to receive tornado warnings the rest of the night.  11:55p Tuesday: New tornado watch has just been issued for most south central (including Wichita), southeast and east central Kansas.  This watch is in effect until 7am Wednesday.
