WADING RIVER - The community of Hampton Bays is concerned that Suffolk County has started housing homeless families at the Hidden Cove Motel in Tiana Bay. Neighbor Gail Liner says she was surprised to learn that the Department of Social Services wants to remove all paying guests from the motel by Nov. 30 and use the entire facility as a temporary homeless shelter. Community Housing Innovations runs the shelter and says its residents must adhere to a strict set of rules, so having a mix of paying guests and shelter residents doesn't work. The group says neighbors shouldn't be worried if the motel becomes a full-time shelter since it will have better on-site security. Some Suffolk County lawmakers, however, say turning the motel into a full-time homeless shelter isn't a done deal yet. "I think there must be better options than a waterfront hotel," says Legislator Jay Schneiderman (I-Montauk).Suffolk Social Services says there are more than 500 homeless families in the county, about 200 of which are being housed in hotels.
