  2. 2. 2 Overview of Jamaica Bay  Jamaica Bay is designated for primary contact and it’s tributaries are designated for secondary contact  Water quality in Jamaica Bay is better than its been in 100 years and supports a wide variety of wildlife but there are still impairments:  Waters tend to be eutrophic  Seasonal low DO levels  These water quality impairments are linked to high nutrient loadings in conjunction with man- made physical alterations  DEP is upgrading all for of it’s WWTP that discharge into Jamaica Bay for Step Feed BNR  Loss of the marsh islands is another critical issue within Jamaica Bay  DEP has partnered with ACOE to restore many of these marsh islands ($13M funded)
  3. 3. 3 Historical Water Quality
  4. 4. Additional Water Quality Studies  In 1995/96 DEP conducted comprehensive water quality and ecological studies to calibrate JEM  Subsequent comprehensive water quality, ecological, and finfish studies were conducted in 2005/2006  Ongoing Jamaica Bay Science & Resiliency Institute will be refining JEM  DEP to conduct a comprehensive Post Construction Monitoring Plan from 2016 thru 2019 4 Water QualityWater Quality MarshlandMarshland UlvaUlva PhytoplanktonPhytoplankton

Editor's Notes

  • Historically, the average depth of Jamaica Bay was much shallower than it is today. The north channel of the bay was dredged (for port considerations), as was Grassy Bay (for fill for JFK airport). Depths in these portions of the bay increased from historical levels of 2-4 ft MLW to as much as 35-45 ft MLW. In addition, the construction of the JFK runway and development of the Broad Channel community has reduced the exchange of waters in Grassy Bay with the rest of the Jamaica Bay system.
  • DEP’s efforts to control and reduce CSOs began with the construction of the Spring Creek facility in 1974. It is currently undergoing a design upgrade at a cost of $87 million (M).
    Construction of the 50 million gallon Paerdegat Basin storage facility was recently begun; total construction costs are $300 M.
    The wet weather capacity of the Jamaica Bay WPCP will be expanded by 50 millions gallons per day (MGD) to reduce CSO overflows to Bergen Basin.
    Additional sewers will be constructed to reduce CSOs to Thurston Basin.
    A facility plan is being developed for Fresh Creek that will include cleaning of the sewers and will likely require a storage facility and an increase of wet weather capacity at the 26th Ward WPCP by 50 MGD.
