Kan. Stat. § 12-17,148
A separate fund shall be created for each district and each project and such fund shall be identified by a suitable title. Except as otherwise required by the secretary of transportation in connection with a loan to the municipality from the Kansas transportation revolving fund, the proceeds from the sale of bonds, transportation revolving fund loan, any special assessment and transportation development district sales tax authorized, levied and collected under this act by the municipality and any other moneys appropriated by the governing body for such purpose shall be credited to such fund. Such fund shall be used solely to pay the costs of the project. Upon payment of the principal and interest on the bonds, if any, the municipality shall have the authority to spend any moneys remaining in the fund for the purposes for which local sales tax receipts may be spent.
