Subsequent damages can be further divided into the following categories: (1) Someone damaged the infrastructure at some time after its initial installation; (2) Someone failed to provide the required industry-standard maintenance; and (3) The damage was caused by a natural event such as an earthquake, tsunami, landslide, storm, or fire.
Although these are subsequent damages from the past, this is not about the past. The fact is, public infrastructure is being damaged today, unless the public agency has an effective program to protect and maintain it.
