Alfortville was sandwiched between the Marne and the Seine and came to a point just at the place where the two waterways merged. When both rivers overflowed and the two bridges closed, many residents of Alfortville were essentially stuck. With only about eleven percent of the town’s streets served by sewer lines, the water had nowhere to go, instead forming large pools throughout the village. Many homes in Alfortville were immediately overcome by the floodwaters and turned into little more than piles of debris.
