Police Commissioner Ray Kelly honored a cop in Coney Island yesterday for saving two parents and their baby from rushing floodwaters during Hurricane Sandy.

Officer Jonas Guisao received a plaque at the 60th Precinct Hurricane Sandy recognition luncheon.

The night of the hurricane, Guisao was out deploying boats to save stranded Coney Island residents — and wound up getting stranded himself.

At the same time that his truck went dead, Guisao spotted a stranded family in the water.

“As I was getting out of my truck to get them, [a Fire Department vehicle] passed by and I passed the mother and the father and the baby to them,” Guisao recalled.
