significant event today, which is the bios cresting the banks. >> this is unprecedented for houston and you have not experienced this before? >> respectfully yes, we did in tropical storm alison in 2001 and the worst flooding in houston history. we had some 30 inches of rain in about a 24-hour period and much of the area that is underwater today and in fact a vastly large area was under storm because of tropical storm alison. because we have so many bios running through the city in a significant rain event, we have street flooding, what is rare is to have property flooding. >> mayor parker thank you for
