What would be the impact of?
... being flooded out of your office during tax season?
.... a blizzard that shut down your area for several days?
.... a fire in your office building? (water and smoke tend to travel far and fast)
.... an ice storm that cuts power for four days? internet for five days?
.... a fire in a commercial building two blocks away?
.... a chemical spill in a near by truck depot?
This analysis depends on your location, the type of structure, the type of neighbors (in the building and in the neighborhood), and your geography and topography.
