Major Post-Sandy Infrastructure Projects
Rebuild by Design-Hudson River . The $230 million project includes new
bulkheads, floodwalls and sea walls, soft landscaping and green roofs, stormwater
runoff systems, and improvements to outfalls and pumping stations.

The Big U . This planned $335 million project will include a continuous 10-mile
flood barrier disguised as a park. It will snake around lower Manhattan and
include innovative features, such as deployable walls, to protect buildings and
property.

Absecon Island . The U.S. Army Corps of Engineers
and contractor J.H. Fletcher Creamer and Son are
WV building two sections of a sea wall and rebuilding
portions of the Atlantic City boardwalk along the
Absecon Inlet as part of a $63.3 million shore
protection initiative.

Bay Park Sewage Treatment Plant . Completed
in August 2016, the project uses concrete and
earth walls and an elevated electrical system to
protect systems from future floodwaters. It
includes a bike path and park.

Coney Island Flood Defense System . The proposed
project would involve the construction of various
systems, including tidal barriers, water circulation
systems and natural stormwater treatment areas, to
reduce risk for 46,000 residents and 6,000 buildings.

Coney Island Yard . Among the permanent protections for
the $107 million project: a 2.5-mile-long flood wall with
eight floodgates, 900,000 gallons of underground storage
and two pump stations, the complete replacement of one
bridge with a new flood-proof structure and a major retrofit
of a second bridge to also make it flood-proof.

Willoughby Spit . This U.S. Army Corps of Engineers project is part of a $34.5
million initiative to reduce storm damage risk to infrastructure along a 7.3-mile
stretch of waterfront in Norfolk, Virginia. Once complete, it will create a
protective berm 5 feet above mean low water for a 60-foot-wide beach.

and schools and public offices were shuttered. In New York City,
11 million daily commuters lost access to bus, subway and rail
services, and at least 110 homes went up in flames in the Breezy
Point neighborhood of Queens. By the time the storm subsided,
Sandy established itself as the second most destructive hurricane
in United States history, after Hurricane Katrina.
John Boulé, senior vice president at Fairfax, Virginia-based
Dewberry, says that before Hurricane Sandy, a pair of severe tropical storms rolled through the region in 2011. These storms were a
"wake-up call" for public agencies, private businesses and citizens.
"The earlier storms served as a dress rehearsal for how to prepare,
evacuate and manage major infrastructure systems such as mass
transit. Yet, after Sandy, the entire mindset shifted. There was a recognition that the planning and execution of capital projects had to
change. There had to be a greater focus on resilience," he says.

Not surprisingly, the initial response centered on restoring power
and operations for transportation systems and infrastructure. For
example, at the Coney Island Yard, a 110-acre site in Brooklyn
that handles maintenance for approximately 1,800 New York City
subways cars, STV Group and others worked with officials to clear
flooded spaces and fix damaged electrical controls. After the storm,
the site resembled a huge lake. Although workers managed to get
subways cars to higher ground before the storm struck, automated
switching systems were inoperable for weeks. Operators had to
switch and move cars manually. "The facility was built in 1926.
Critical infrastructure was below grade," Riverso says.
High-rise buildings in New York City were also inundated. Subterranean flooding was common. "Companies that were impacted
included large telecommunications firms with critical systems and
assets," says Edgar Westerhof, flood risk and resiliency lead for

U.S. Army Corps of Engineers' contractors from Great Lakes Dredging and Dock Co. pump sand dredged from the bottom of the
Chesapeake Bay up to Norfolk, Va.'s Ocean View Beach. The sand is part of a $34.5 million project to reduce storm damage risk to
infrastructure along a 7.3-mile stretch of waterfront, which is susceptible to damage during costal storms.
