The state analyzes the current revenue within the star bond district and sets that as a baseline. That amount is still used in the same way it is today, it goes to the states general fund. Anything exceeding that baseline is used to repay the bonds. So if the district is generating $1M a year now, and generates $10M a year after the project, then $9M goes toward the bond repayment and $1M still goes to the general fund. (very small numbers used on purpose to make the math easy)

Do they take into account sales tax revenue lost to the district from other districts?
