The order shall fix the day of the election, shall specify the amount of the bond issue, and shall state in general terms that the money raised from the sale of the bonds shall be used for the acquisition of rights of way for, and the construction of, boulevards in the district.

If the election is called for the payment of a contract already entered into by the commission, the order shall state the terms of the contract in such manner as will advise the electors of its contents.  Any money raised by means of a bond issue which remains on hand after the acquisition of rights of way and the construction have been completed, shall be expended in the betterment and maintenance of the boulevard.
