I took the 2nd paragraph meaning as protecting infrastructure/public works like power, water, hospitals, etc. A call out for those worried that went through 9/11 kinda thing. I've lived in an area where those have been attacked and the disruption of one incident can lasts weeks from a single bullet. Emergency management officials and commissioner are the two key points and this is a city mayor, not state senator or federal leanings.

edit to add: also meant to include religious and anything that might be loosely related to Iran or culture from the area (bigots don't tend to scrutinize connections), leaving it as "sensitive locations" is better than specifically spelling out where extra protection is being laid out to any bad actors wanting to instigate.
