Milwaukee is spending $100 million on a metropolitan flood-control project, hoping to avoid future flood damages that have cost that much since 1997. The centerpiece of the plan is a 17-ft-diameter, half-mile-long tunnel that will drain up to 3,405 cu ft per second of water from a flood-prone creek into a 315-million-gallon detention basin. Slide Show Photo: Mike Larson Tunnel diameter is more than 17 ft, designed to quickly channel stormwater to detention basin. When heavy rain causes nearby Underwood Creek to overflow, the new tunnel will drain the excess water to a 65-acre engineered detention basin that will slowly
On March 3, the U.S. Energy Dept. formally withdrew its application with the Nuclear Regulatory Commission to make southern Nevada the site of national nuclear-waste repository. The move comes after 23 years and $38 billion in studies at Yucca Mountain, 90 miles northwest of Las Vegas, where it had planned to store up to 77,000 tons of radioactive waste from 80 sites in 35 states. The construction price tag was estimated at about $100 billion. It leaves the waste problem unresolved and the federal government exposed to utility lawsuits. Since 1983, ratepayers have paid over $33 billion into the Nuclear
Enbridge Inc. is itching to get going on its proposed Northern Gateway Pipeline stretching from outside Edmonton, Alberta, to Kitimat, B.C. Initially introduced in 2005, the 727-mile pipeline project is headed to Canada's National Energy Board and the Canadian Environmental Assessment Agency for joint review "very soon," according to Jennifer Varey, spokesperson. If approved, construction could start in 2012. Calgary, Alberta,-based Enbridge plans to transport 525,000 barrels per day of petroleum in the 36-inch west-moving pipeline and 193,000 barrels per day of condensate—a product used to thin petroleum products for pipeline transport—in the 20-inch east-moving line. The project, estimated at
In a strongly worded response that was not a surprise to the U.S. military, a San Francisco-based official of the U.S. Environmental Protection Agency has raised concerns about the potentially major environmental and infrastructure damage from the planned relocation of thousands of Marines and others to the tiny Pacific island of Guam. EPA is concerned the movement of thousand of U.S. Marines, construction workers and others to Guam will harm its sensitive ecology and overstress infrastructure. In a Feb. 17 letter to Roger Natsuhara, acting assistant U.S. Navy secretary for installations and environment, EPA regional administrator Jared Blumenfeld says the
De-authorizing navigation on the Missouri River would do wonders to ensure a robust water supply for irrigation and recreation in the Midwest—although at a cost to certain interest groups, many of them downstream.

Every option is on the table as the U.S. Army Corps of Engineers launches a study to challenge whether the “eight purposes” enshrined in a 66-year-old federal act that governs water management policy on
A joint U.S.-European group has presented the low bid to analyze the options for a vehicular crossing at the Atlantic entrance of the Panama Canal, officials said on Monday. Photo: C.J. Schexnayder The Third Lane Expansion project will be built roughly at the site of a previous excavation by the U.S. Army Corps of Engineers, visible to the left of the Gatun Locks. San Francisco-based URS Corp. and the Danish firm COWI A/S submitted a bid of $895,000—the lowest of five tendered—to examine the possibilities of a permanent crossing at the historic waterway’s Atlantic entrance that will allow uninterrupted traffic
The U.S. Environmental Protection Agency declared on March 2 that the Gowanus Canal will be added to the list of federal Superfund cleanup sites. The heavily polluted canal runs through an old industrial sector in the New York City borough of Brooklyn and empties into New York harbor. EPA’s decision will set in motion a $500-million, decade-long effort to clean up the former industrial canal, which EPA says is contaminated with PCBs, coal-tar waste, heavy metals and volatile organics. Mayor Michael Bloomberg (R) had opposed the EPA designation, fearing it would endanger real estate developement plans for the area. EPA
Hours after Chile was hammered on Feb. 27 by one of the most powerful earthquakes in its history, President Michelle Bachelet made it clear the country already is preparing for recovery. Photo: AFP/Getty Images The naval port city of Talcahuano, about 20 km from Concepción, was devastated by a tsunami about an hour after the quake, catching unwarned residents by surprise. No tsunami warnings were issued for Chile’s coastal towns.

The most powerful earthquake to strike Chile in a generation may have left hundreds dead and the South American nation’s infrastructure in tatters, yet the fact the destruction was not far worse is being cited as a testament to Chile’s application of improved building codes and decades of efforts to prepare. Slide Show Photo: AP/Wideworld Nine died and seven were missing—with some believed trapped alive behind a wall that took the load—when the 70-unit Alto Rio Apartment complex in Concepción rolled off its foundations in the Feb. 27 quake. Investigators likely will study the structure’s perfomance for what worked and
