Natural Defenses

Oysters

From 17thto the 19th centuries it is estimated that
ysters occupied over 350 square miles of the Hudson-

Raritan estuary between Sandy Hook and Ossining, NY.

Oysters are now functionally extinct, with a loss greater

than ninety-nine percent in the Hudson-Raritan Estuary Marshes

Rule of thumb 3 miles marsh, 1 ft surge dissipation
Loder (2012) – Up to 1.2 m wave height reduction and

35% surge reduction (modeling)

– As marsh elevation decreases, surge decreases and waves increase – 20 km x 20 km marsh

Cuyahoga River Green Bulkhead Project

One of the most heavily polluted waterways

in the U.S.

Heavily utilized industrial shipping channel

Option 1 – CHUBS (Cuyahoga Habitat Underwater Baskets)

system uses plant pillows which sit in baskets that hang by chains at various heights, nestled within the wall's corrugations

Option 2 - Pocket Habitat Option 3 – Tiered Wall

CHUBS are planted in locations with damage An sheltered area is created and only

r corrosion but have sound lower portions. a portion of a bulkhead is replaced.

Alternative Concrete Solutions

Durable material that is

frequently used to construct marine structures

Poor material for biological

recruitment

Can be altered physically and

chemically

Decrease the PH of the concrete
Texturize the surface
