NYC Flooding with Historic Rainfall

By the end of a single day, historic rainfall levels had affected most parts of the city with Brooklyn and Queens experiencing the most impact.

The city’s Environmental Protection department issued an advisory for most of the area’s waterways – due to potential sewage runoff. New York City’s sewage system can handle approximately 1.75 inches of rain an hour. However, as record-breaking rain fell, weather stations located in Central Park and many parts of Queens were recording more than 2 inches of rain per hour. Areas of Brooklyn were receiving nearly 3 inches per hour.

The overall tends to flow toward waterways which can often contains contaminants and more than just rain. The flooding can overwhelm sewers and wastewater treatment facilities which causes untreated polluted water to flow directly into rivers and creeks. Many people reported sewage backing up into lower level apartments, which were also flooding from the streets.

Transportation authorities attempted to avoid service interruptions, but due to uncontrollable flooding and overflow, there were serious interupptions and shut downs. Many subway lines were taken out of service or delayed due to flooding throughout the system.

Schools were open as normal for the most part, but many students never made it to class. Some of them were stuck on their way in. The Department of Education reported attendance at 77% — which is well below normal rates. The students who did make it to school had to figure out how they would get home through the floodwaters.
