Meh that wouldn’t have changed anything. It’s NYC. Lots of people live there. They have places to go. All you can do is warn about impact and communicate that as best as you can. You can’t tell people what to do. You just need to communicate things as best as you can. They have to take that info and do what they please. This was probably 1/100ish year event? Maybe more? Every time there is a risk of FFW, you aren’t going to keep people off the roads or have 300,000 people leave their basement apt.
