Yes, the port must be re-opened.
But as I've posted on other threads, any building under three stories will need to be condemned and razed due to contamination.
The cost of remediation for these buildings and homes is prohibitive.
Add to that the folly of rebuilding where they don't belong.
"any building under three stories will need to be condemned and razed due to contamination."
If they use lumber in the fill this will create more problems when it rots. (And creates habitat for their formosa termites.) They should take all lumber from the razed structures and burn it their electrical power plants. (In the coal burning ones anyhow.)
