I've had to deal with this on a very odd level.
Last year I was purchasing a house. I had already put in my offer, it was accepted, just all the rest had to be finalized. A lady from ADOT (Arizona Department of Transportation) left a note on my door about discussing the widening of the freeway near the apartment and how it would affect me. I was moving out in 4 months, I didn't think it mattered, so I ignored her. She persisted and finally we had a meeting. The freeway widening was going to be demolishing my apartment building in October. She said that I was eligible for relocation fees and rent equivalent reimbursement. I told her that I was already in the process of purchasing a house and was on a month to month lease. I didn't think I really qualified, as we were moving out in July. She insisted, I refused, she continued to insist, I asked if it was going to be taxed, she said no, and I said GREAT! A few months later I received ~$1700 for moving expenses - which we didn't need because we did the move ourselves with the help of friends and family. I also received ~$1700 in compensation for the difference in what we were paying and what we would pay at a similar apartment for the next 12 months. I really didn't understand how or why I was getting this money, but I did. Almost a year later, the lady calls me and says, oh yeah I forgot that you get reimbursed for your home inspection. Send me the receipt and we'll get you that money too.
tl;dr Apartment building was going to be demolished, I was moving out. Got lots of money I didn't deserve.
So I'm not sure its really an eminent domain story, as ADOT was in negotiations with the owners of the property. Also, the destruction/construction was supposed to start last October, it just started last month. Lots of red tape and contract issues apparently.
