Notwithstanding the fact that the proceedings under this part have provided that assessments are to be levied as contemplated by Section 11202, the legislative body, at any time and either before or after the adoption of the resolution provided for in Section 11311, may determine that such assessments shall not be levied. In lieu thereof the legislative body may provide for the payment of all or any part of the amounts referred to in Section 11501 out of general funds of the city or out of any other available funds. No money available for expenditure within the city from the proceeds of any tax, license or fee imposed by any public agency upon the ownership or operation of vehicles or the fuel used therein shall be used to pay such amounts, except as may be permitted by Section 11005 of the Revenue and Taxation Code. The legislative body may also provide at any time for the payment of all or any part of such amounts by including the same as part of the incidental expenses in any proceeding taken for the improvement of the pedestrian mall under the Improvement Act of 1911, the Municipal Improvement Act of 1913, or similar special assessment law for the improvement of the pedestrian mall.
