I'm retired and have lived in the area for 28 years. I ride about 20 miles a day on the bike paths and roads. I sometimes ride up to New Rochelle or a short ride to the end of City Island. The photo you are showing is just water pooling in the parking lot. The parking lot holds 12,000 cars and is blacktop. It's old and not perfectly level. The pooling water is just a few small sections. It's a bird bath for the sea gulls for a bit of time.
