What's happening today is a result of a long-term history of poor design or mismanagement. A lot of sewer lines have been down there since the '50s and '60s and we have an increased amount of people and therefore more usage.
The sad fact of human nature is when something of this magnitude happens, people do finally pay attention.
If you're gonna do that, make sure it's safe, and have full disclosure in that sense. Take care of the people you're trying to bring in.
