According to this, NO has inspected 128,000 homes on the east bank, and they will soon raze 2,500 of those. Around another 3,000 were also marked as inhabitable, but their status will be verified before a final decision is made. But:
The vast majority of the homes in the city -- about 68 percent -- were coded yellow, or judged to be sound but with structural damage. And [chief technology officer, Greg Meffert] said it's likely that as many as half of those homes, or about 43,000, will eventually be demolished. But city officials hope to leave that decision in the hands of the homeowner as much as possible, he said.
