What the hell just happened?!

Just got this from the bank that holds my mortgage. Can this be right? What the hell happened to cause a 50% increase in my property taxes?! Quick googling didn’t turn anything up. Any city tax knowers here able to shed light on this? The only thing I can think of is that we are in a proposed up zoning area for the new development plan but as far as I know that hasn’t passed yet. What is going on here? Is anyone else seeing anything like this?
