NEW DORP BEACH — Residents of New Dorp Beach are continuing to cleanup after Hurricane Sandy devastated their community — and many are still wondering when power and vital relief was getting to them. Water still covered parts of Cedar Grove Avenue, which is just off the beach in the Lower Bay, and some houses were completely destroyed. Neighbors slowly cleaned their property, some seemingly unsure where to even start addressing the damage. "We need help," said Caroline Tresca who lives in New Dorp.
