Basement Flooding and Foundation Damage from Water-Table Rise in the East New York Section of Brooklyn, Long Island, New York

From purpose and scope: The purpose and scope of this report is to present the factors that have caused the water-table rise in the East New York section of Brooklyn. The rising water table in Kings County is not sudden or new; it has a history of more than two decades. It will refocus attention on the problem of changing ground-water levels in areas where intensive ground-water pumping has ceased or is occurring.
