NEW ORLEANS -- In a big step toward restoring the pulse and soul of New Orleans, the mayor announced plans Thursday to reopen over the next week and a half some of the Big Easy's most vibrant neighborhoods, including the once-rollicking French Quarter.\nThe move could bring back more than 180,000 of the city's original half-million residents and speed the revival of its economy, which relies heavily on the bawdy, Napoleonic-era enclave that is home to Bourbon Street, Mardi Gras, jazz and piquant food.\n"The city of New Orleans ... will start to breathe again," a beaming Mayor Ray Nagin said. "We will have life. We will have commerce. We will have people getting into their normal modes of operations and the normal rhythm of the city."\nThe announcement came as President Bush prepared to propose a sweeping plan for the federal government to pick up most of the costs of rebuilding New Orleans and the rest of the hurricane-ravaged Gulf Coast -- estimated at $200 billion or beyond.\n"There is no way to imagine America without New Orleans, and this great city will rise again," the president said in remarks to delivered to the nation from the French Quarter's Jackson Square.\nNagin said the "re-population" of the city would proceed ZIP code by ZIP code, starting Monday in the Algiers section, a Creole-influenced neighborhood across the Mississippi River from the French Quarter. The city's Uptown section, which includes the Garden District's leafy streets and antebellum mansions, will open in stages next Wednesday and Friday. The French Quarter will follow on Sept. 26.\n"The French Quarter is high and dry, and we feel as though it has good electricity capabilities," the mayor said. "But since it's so historic, we want to double- and triple-check before we fire up all electricity in there to make sure that ... if a fire breaks out, we won't lose a significant amount of what we cherish in this city."\nThe plan came a day after government tests showed that New Orleans' putrid air is safe to breathe, even if the receding floodwaters that still cover half the city remain dangerous from sewage and industrial chemicals.\nWhile the areas set to be opened were never part of the 80 percent of New Orleans under water, they still suffered from the failure of services that left them prey to the looting that gripped the city after Hurricane Katrina hit Aug. 29\nNow, the designated neighborhoods have 70 percent to 90 percent of their electricity restored, and have water that will be good for flushing and firefighting, if not drinking. The sewer system works, trash removal is running, and at least two hospitals will be able to provide emergency care, authorities said.\nAnd Nagin said the city's convention center, which became a symbol of the city's despair when thousands of weary refugees gathered amid filth and corpses, will now become a hub of the rebuilding effort. Three major retailers will set up there to sell lumber, food and other supplies.\nSecurity will be tight in the reopened neighborhoods. Nagin said a dusk-to-dawn curfew will be enforced, and residents and business owners will be required to show ID to get back in.\nIf the initial resettlement goes smoothly, Nagin said other areas will slowly be brought back to join in what he called perhaps the biggest urban reconstruction project in U.S. history.\n"My gut feeling right now is that we'll settle in at 250,000 people over the next three to six months, and then we'll start to ramp up over time to the half- million we had before, and maybe exceed that," he said. "I imagine building a city so original, so unique that everybody's going to want to come."
\nAlso Thursday, Nagin asked mayors across the United States to take censuses of displaced New Orleans residents so the city knows where they are and can communicate with them about reconstruction.
