What can the residents of New Orleans, Louisiana do to help rebuild their city?

The two year anniversary of Katrina will be this month. Not much progress has happened there since the storm. My husband and I go down there at least once a month and help out all we can. It seems that the city is stuck in a non productive rut. What do you think would help out? The city is a great place with some great people. It is just filled with so many problems
