From and after the adoption of an official map, the legislative body may establish, by resolution or ordinance, a fund for the advance acquisition of rights-of-way for highways of the county or municipality shown on the official map. In establishing the fund, any revenues may be used that are available for highway purposes, including the state-shared motor fuel and gasoline taxes.
Taxes may be levied for the purpose of establishing and maintaining the fund and bonds may be issued for the purpose of establishing and maintaining the fund in the same manner and subject to the same conditions as bonds are authorized to be issued for highway purposes.
State and federal highways shown on the official map shall be given appropriate consideration in the expenditure of available state or federal funds for the acquisition of rights-of-way.
