I don't know what happened in this particular case, but given how long it took to hash out the details, I would expect that alternative housing was found for the displaced tenants.

I really should ask around; this detail seems to be something that the various newspapers aren't covering.

I agree that having to figure out alternative housing for yourself would be very, very bad for a few classes of tenants. I mention a mitigation in the last sentence of the comment to which you replied. :)
