STREAM ONE HOW DOES FLUSHING MEADOWS HYDROLOGY WORK ? Blue dashes show general historical runoff paerns STREAMS DIVERTED FROM SALT MEADOWS NOW GO INTO SEWER OVERFLOW INSTEAD 1934, 16 May - Mountains of ash, used to fill the Flushing Meadows marshland, future site of the 1964 World Fair. Drain pipes are being laid to drain dal and spring fed streams 1934 – 11 March, Construcon of Grand Central Parkway across Flushing Creek and the Flushing Meadows dal marshes BURIED STREAM

1924 Fairchild Aerial with new rail line allowing landfilling of Flushing Meadows with coal ash. Marsh streams would be diverted into new sewer pipes (causing sewer overflows into bay when it rains)

“This is a valley of ashes - a fantasc farm where ashes grow like wheat into ridges and hills and grotesque gardens; where ashes take forms of houses and chimneys and rising smoke and finally, with a transcendent effort, of men who move dimly and already crumbling through the powdery air”

WHERE SHOULD WE PRIORITIZE COMMUNITY SEWER OVERFLOW REDUCTION PROJECTS ? (RAIN BARRELS, RAIN GARDENS, STREET CREEKS, ENHANCED TREE PITS, ETC) FLUSHING BAY GETS AROUND Paler water is from eutrophicaon from about 10 dumpster load of sewage poop that gets deposited every year by the 3 BILLION GALLONS OF SEWAGE PER BB-006 and BB-08 combined sewer overflow . The sewage YEAR nutrients cause eutrophicaon (the milky color) and affect fish survival by lowering oxygen levels. High synthec estrogen levels (from human birth control pills), heavy metals and oils are other pollutant problems affecng local ecology survival and health.
