HIGHLANDS RANCH, Colo. -- April 16, 2013

ARCADIS (EURONEXT: ARCAD), the leading pure play global engineering and
consultancy firm, has been awarded two contracts to help restore Louisiana’s
coastal wetlands. For both projects, ARCADIS US will focus on diverting
valuable sediments and nutrients from the Mississippi River to start
rebuilding the thousands of acres of land now being lost every year. The two
projects together represent a potential capacity of 85,000 cubic feet per
second (cfs) of sediment-rich Mississippi River waters to build up to 25,000
acres of wetlands over 50 years.

For the “White Ditch Freshwater and Sediment Diversion” project, the U.S. Army
Corps of Engineers New Orleans District selected ARCADIS US to design a
freshwater and sediment diversion system south of New Orleans. The goal of the
program is to offset the trend of coastal deterioration brought on by years of
human intervention on the river. Delivering valuable land-building sediments
from the Mississippi River will help maintain the current area of marsh
habitat and its ability to reduce vulnerability to coastal storms, waves and

The other ARCADIS US contract is for the Lower Barataria Sediment Diversion
Project, part of the state of Louisiana Coastal Protection and Restoration
Authority’s larger, $50 billion program of coastal restoration and protection.
Intended to rebuild the barrier islands, shoreline and coastal marshes of
Caminada Headland and Shell Island, the program is designed to restore both
habitat and the sustainability of the shoreline itself. An integral component
of the overall program, the Lower Barataria Sediment Diversion Project is
expected to create between 9,000 to 12,000 acres of wetlands over a 50-year

Restoring coastal wetlands and natural barriers are all part of a strategy
critical to the region known as “America’s Wetland.” Reconnecting the
Mississippi River and its fresh water and sediments to the delta will help
rebuild important ecosystems and their ability to make the coastal area more
resilient to storms.

“The coastal wetlands are more than a land mass. They are integral to the
economy and culture of the region,” notes Rudy Guichard, senior vice
president/director of ARCADIS US. “Not only do they act as part of the
multiple layers of defense against storms and flooding, these areas provide
the habitat for fish and wildlife that are part of Louisiana’s economic

“As a global leader for designing sustainable coastlines and waterways,
ARCADIS believes in developing multi-faceted, integrated solutions to restore,
protect, and enhance sensitive coastal areas. We are working with the Army
Corps and the state of Louisiana to design these projects with and from
nature, in effect using nature as a dynamic engine. These projects will
harness the massive power of the Mississippi River to bring sediment and
nutrients to the basin. You couldn’t afford to dredge the same amount in the
same time.”

Anyone who has lived in the region knows that this work can’t happen fast
enough. According to the U.S. Geological Survey, analyses point to the
Louisiana wetlands disappearing at a rate of more than a football field an
hour. These diversion projects are an important part of the overall effort to
both maintain existing wetlands and prevent future losses of valuable acreage.
