But the buses can be an inconvenience, some say.
"They just stop in the middle of the street, and you have to go around them," said Jadii Joseph, who lives in one of the Make It Right homes.
Wolken said she doesn't need the Lower 9th to show evidence of 2005 destruction. Tour buses are permitted in other areas bouncing back from Katrina. "But everybody wants to see the Lower 9th Ward," she said. "It's the most popular."
Kelly Schulz, spokeswoman for the New Orleans Convention and Visitors Bureau, said the Katrina tours kept the tour companies in business in the storm's aftermath when travel to the city plummeted.
"These tours are important," Schulz said. "People come to New Orleans from all over the world, and they want to see the Lower 9th Ward just like visitors to New York want to see the site of the World Trade Centers. It's human nature. It's curiosity. We certainly need to be respectful and not cause more suffering, but seeing these areas in person brings needed attention."
