No Retreat From The Coastline - Sarah Crean, Gotham Gazette 6/11/2013

“Striking a tone of defiance, Mayor Michael Bloomberg said today that New York City will not retreat from its coastline despite the threat of rising sea levels and the possibility of storms more catastrophic than Hurricane Sandy. On the contrary, he argued, the city should not only continue to build along the waterfront but build better.”

Bay Head NJ | storm barrier

Union Beach NJ | no storm barrier, no house

FARROC | dune living

Staten Island NY | expanding dunes

Staten Island NY | expanding wetlands and living shorelines

Jamaica Bay NY | aquatic habitats

Eelgrass Learned what works and doesn’t work Able to determine best planting methods Water quality not limiting – bioturbation and hydrodynamics

Oysters Reef Ball pilot projects successful

Future oyster sites in NY harbor require: Lower energy Greater depth Structural protection

Reducing the risk of flooding: 1.Reduce negative impacts of storm events

• reducing wave heights and velocity • reducing water velocities • reducing surges

1.Reduce day-to-day erosive forces No one natural coastal feature can do all of this
