New York City Department of Environmental Protection is racing ahead with irresponsible plans to destroy the most successful oyster, mussel, and salt marsh restoration project ever done in New York City, or anywhere else.
These projects, approved by New York State Department of Environmental Conservation, have for 10 years pioneered new methods for restoring these valuable ecosystems, providing habitat for birds, fish, and shellfish, protecting shores from erosion, and improving coastal water quality, which could save the City billions of dollars in adapting to and mitigating global warming and global sea level rise (please see current photos attached).
The MacNeil Park projects have shown for the first time how to restore vibrant marine ecosystems to barren shores where everything had died from toxic waste dumping at the site for more than 50 years. They not only restored life to a wasteland, but showed for the first time how to grow these organisms under extreme stress conditions that they normally could not survive. Our team is now expanding the project to fill in all the gaps.
10 years of work will be destroyed if DEP puts the storm drain where they intend. This will not only flush water shown by chemical analysis to have illegally high concentrations of toxic lead, copper, zinc, hydrocarbons, and untreated sewage, but the water flow will wash away the beach sediment and cause severe local coastal erosion at a site that is a designated public recreational area and entry way for kayaks.
Using the Biorock restoration method, we had 100% survival of oysters during the winter when 93% of control oysters died. The few surviving control oysters stopped growing in winter, and their shells were chalky, crumbly, and dissolving due to cold acidic water, but Biorock oysters grew all winter, and their shells were bright and shiny with no dissolution.
The Biorock restoration method has grown salt marsh lower in the intertidal zone than salt marsh grass can tolerate, it grows taller, faster, greener, and spreads faster than controls, grows back in larger spreading patches after every winter when controls die, and has prolific root growth and mussel populations which bind sediment and prevent erosion by waves.
The mussel growth has been so extraordinary that in a few years we have raised the height of the beach where we are growing them by up to a foot, much faster than the rate of global sea level rise, about an eighth of an inch a year. Therefore, we are able to grow beaches upwards at places where they are now washing away from erosion.
Oysters have spontaneously settled near our projects, but not away from them, showing that oyster settlement is increased by the Biorock process. These oysters have shown exceptionally high growth and survival.
These incredible results show for the first time that it is possible to extend salt marshes seaward to protect coasts from erosion. All salt marshes in the US are rapidly eroding and collapsing into the sea due to global sea level rise and increased storm wave strength caused by global warming. Jamaica Bay is the worst example of this. The methods pioneered at the McNeil Park project could save Jamaica Bay salt marshes, and help protect Kennedy Airport from flooding by the sea and storm surges (remember Sandy!).
This destruction of a historic restoration project is entirely un-necessary! There is an existing storm drain at the site that runs out past the project to the low tide mark, built long ago to prevent contaminated water washing directly onto the beach. But instead of using it or upgrading it, DEP plans to dump polluted water directly at the shoreline high tide mark, and flush away 10 years of extraordinarily successful work with polluted water!
The bulldozers are right at the edge of the project, ready to move into action unless DEC can get them to responsibly act to save New York City’s precious green shorelines! We urgently appeal for your help to save the projects that will make New York the leader in natural shore protection.
