It was found in 2005 that they can take your property and give it to another private party simply by making the claim that its for the public good. This has been used to take homes from people so they can be bulldozed and replaced with new construction, the idea being that the larger tax base is for the public good. This makes the power in effect limitless as you can claim almost anything is for the public good.
A major problem I have with this is appraisal prices often don't jive with reality. For example in San Fransisco houses almost always sell above asking, if the government were to step in and give the land away to a private person at asking they would be in effect getting a discount. Similarly my own home has had a lot of work put into it that doesn't effect it's appraisal price meaningfully, if forced to sell at that price I'd lose money.
