New Orleans poor areas still vulnerable to flooding

WASHINGTON (Reuters) - Poor areas of New Orleans hardest hit by Hurricane Katrina remain vulnerable to flooding because flood control improvements have not been completed, a U.S. official said on Thursday as Tropical Storm Gustav threatened a possible new strike on the city.

Gustav hit Jamaica on Thursday and was expected to strength in coming days and head toward the U.S. Gulf Coast, possibly threatening New Orleans.

Improvements in flood control have left the New Orleans area better-protected overall than when Katrina devastated it three years ago, and the government is better prepared to handle a major storm, disaster officials said in a telephone news conference.

The U.S. Army Corps of Engineers was also rushing to install temporary flood-prevention structures along the city's Inner Harbor Navigation Channel.

But the improvements are years from being complete and several neighbourhoods remain vulnerable, said program director Bill Irwin of the U.S. Army Corps of Engineers.

"There are those high-level risk areas -- such as the Lower 9th Ward, Gentilly, St. Bernard, New Orleans East and the West Bank -- still," Irwin said. "There are gaps in the system."

The low-income Lower 9th Ward was broadly devastated by Katrina and became a symbol of the storm's human impact. Its rebuilding has been slow.

Irwin declined to say whether the areas he mentioned were more or less vulnerable than before Katrina, but he said the flood-control improvements remained a "work in progress" that would not be complete until 2011.
