When you register your out-of-state car tag for a Florida plate, you might get hit with one (can't remember if they still charge extra for out of state or not). Some counties charge more for new sewer, water, and electric hook-up as opposed to a "transfer" from a previous residence. The idea is that the people growing the population will offset the expense of that growth, such as the need for more roads, more energy consumption, more water, and so forth.
Kinda like charging admission to our giant amusement park.
Yankee go home!

edit: if you're having a new house built, your builder has probably paid impact fees that are built-in to the price of your house. So, those will be transparent to you.
edit again: don't forget to ask about homeowner's insurance. A lot of companies pulled out since Hurricane Andrew years ago. Get your insurance lined up before you make a commitment to buy a house.
