Modeling Solutionaids Major Rezoning Study

摘要

The modeling analysis showed that for the three external WPCPs (26th Ward, Coney Island and Rockaway), there was no difference between future build and no-build scenarios. For the Jamaica WPCP, future no-build and build flows were found to be between 2% and 6% greater than the existing conditions for all three parameters. Fecal coliform loads were estimated to be some 12% less than now due to completion of the Paer-degat CSO retention facility (which will reduce storm flows) prior to 2015. The increases in loadings of the future build condition relative to the future no build state tends to be less than 1 %. CSO discharges are likely to decrease by around 11 % with completion of the Paerdegat facility. Again, there is less than 1% difference between build and no-build scenarios. The analysis confirms that the proposed actions would not have significant adverse impacts for the water quality in Jamaica Bay.
