I don't buy it. I was the mayor of a municipality and if I had acted as you did, just about every house in the area would have been flooded. It's as simple as that.
For example, when you install storm sewers, you make sure that they are big enough to accommodate the flow of rain water. Otherwise, all of the homes will be flooded. If you had been the mayor of a municipality, everyone would have been flooded out. It's as simple as that. There are no two ways about it. You start by making sure that the infrastructure will be up to the task. But that is not what you did. I can't understand the department's actions.
