A new report prompted by Superstorm Sandy says New York City should buy more police boats and develop a system to track patients after hospital evacuations.

It also says the city should line up more generators and take other steps to handle natural disasters.

The self-analysis issued Friday credits the city's preparations and response on many fronts. But it also notes problems.

Among them: Many people didn't evacuate. People ended up staying in shelters too long. Some critically needed city vehicles couldn't get gas.

The report recommends getting more mobile fuel facilities.

It says city staffers should be deployed faster to work with community groups on relief operations.

And it urges working with companies to extend cell phone towers' backup power.
