Here is the info from the port:

We have completed a list of vehicles that remain in the Tchoupitoulas surface parking lot and the Fulton St. Garage utilized by the Carnival passengers that were diverted to Galveston because of Hurricane Katrina. Also information for the Poydras Street surface lot and the Delta Queen parking garage is included. These lists are compiled by make, model, color and license number of each vehicle, and a brief description of damages. Almost all of the damage consists of broken windows, steering column damage and removal of cd players and other electronic equipment. Although none of the parking lots flooded, we do not warrant the drive-ability of any vehicle. Some vehicles have been stolen, so if you do not see your vehicle on the lists, it can be assumed to have been stolen. All of the parking lots are open and accessible during daylight hours. However, there are limitations for entry into Orleans Parish. Some passengers have already removed vehicles. Entry into the Parish is controlled by the City of New Orleans, and we cannot predict when it will be accessible to the general public. For further information on entry into Orleans Parish, please contact the City's office of emergency preparedness at (504) 658-2009.
