As hurricane season dawnedon June 1, Shaw Environmental & Infrastructure Group, Baton Rouge, headed into production mode on construction of a $695-million, 2-mile-long, gated storm-surge barrier to help protect the southeast flank of New Orleans. By midsummer, more than 100 cranes and supply barges will be engaged. Under contract to the U.S. Army Corps of Engineers, Shaw is using a 500-ton crane to set and drive 66-inch-dia, 144-ft-long concrete spun-cast cylinder piles to form the vertical face of the surge-barrier wall. By June 4, a second crane of the same type is scheduled to join in. Shaw expects to drive
A vital storm surge barrier for New Orleans has entered a critical and busy phase. By mid-summer, more than 100 cranes and supply barges will be positioned to work on the more than $695-million, two-mile long, Inner Harbor Navigation Canal Lake Borgne Surge Barrier project being constructed by the U.S. Army Corps of Engineers in New Orleans.

The $13.5 billion in stimulus dollars for water projects announced in February could be just the start of a robust funding stream that will keep contractors busy in California for years to come. More than $441 million in American Recovery and Reinvestment Act money will go to California wastewater and drinking water projects through the existing Environmental Protection Agency/California Water Board Clean Water and Drinking Water revolving fund grant programs. News of the influx of funding without the usual 20% match requirement brought a flood of projects to the state Water Board for consideration. Since the beginning of the year,
The U.S. Government Accountability Office has rejected a protest, from a team led by Parsons Corp., of a $3.3-billion, six-year nuclear-waste cleanup contract for the U.S. Energy Dept.’s Savannah River Site in Aiken, S.C., awarded in December to a team led by the Washington division of URS Corp. GAO declined to explain the rationale for its decision until its opinion is redacted. Parsons would not give a reason for the protest.
A federal judge in New Orleans ruled on March 20 that a civil lawsuit against the U.S. Army Corps of Engineers brought by homeowners who suffered flood damage in Hurricane Katrina in 2005 can proceed. The suit claims the Corps is liable for levee failures along the Mississippi River to Gulf Outlet, a navigation channel. The Corps has immunity from claims arising from flood-control failures but does not have the same protection with respect to navigation infrastructure. Judge Stanwood J. Duval Jr. said “substantial questions” have been raised. Damages could reach $100 billion.
The Environmental Protection Agency on March 12 announced that it will funnel $297 million in stimulus aid to three northwestern states, Alaska and tribal governments for clean water projects. The funds are the first installment of the American Recovery and Reinvestment Act funding to come from the EPA. The individual amounts directed to Alaska, Oregon, Washington and tribal governments will be delivered via existing programs: the Clean Water State Revolving Fund, the Drinking Water State Revolving Fund, and the Tribal clean Water & Drinking Water Set-Aside programs. Alaska will receive $43 million, Idaho will receive $39 million, Oregon will receive
The House of Representatives on March 5 approved legislation authorizing $19.4 billion to fund wastewater infrastructure over the next five years. The House voted 317 to 101 to approve the measure, which would authorize $13.8 billion over five years for the Clean Water state revolving funds (SRF), the principal source of federal funding for wastewater infrastructure. The bill also would provide more than $2.5 billion over five years in grants to address combined sewer overflows and sanitary sewer overflows and $750 million over five years for remediation of contaminated sediments in the Great Lakes region. Introduced just March 3 by
At conferences and on Websites, at research centers and out on windswept coasts around the world, increasing numbers of engineers, scientists, planners and policymakers are gathering to share ideas and lessons learned about a growing threat to one of the linchpins of civilization: the delta regions of the world. Those fragile landforms, built patiently over millennia by the sediment deposited at the mouths of the world’s mightiest rivers, are home to great ports and commercial centers of the global economy. They are, by definition, low and coastal; they also are on the front line to suffer hard consequences from climate
For centuries the Dutch took land from the sea by trapping sediment on tidal flats, diking polders and continuously pumping with windmills to dry the land. Now, faced with a need to bolster a 32-km, sea-facing dike built in the 1930s that turned the IJselmeer into Lake IJsel, an Amersfoort, Nl-based consulting firm, DVH, is proposing a return to old ways: Instead of breaking out heavy machinery and adding width and height to the dike to guard against sea-level rise, it proposes weaving traditional snags of willow reeds on tidal flats to trap sediment on the sea side of the
No city in the world takes climate change and sea-level rise more seriously than Rotterdam. The great port is entwined by the channels of the Maas, Schie and Rotte rivers, which are part of the of the vast delta fed by the Rhine draining Germany, and the Meuse, draining out of France. And it stares directly out at the North Sea from the part of the country known as the Southern Lowlands. As larger cargo vessels abandon a wealth of old shipyards and warehouses in the town to move to bigger docks downstream, redevelopment plans for the huge old port
