The bonds shall be delivered at the place in the State of Oregon designated by the board in the notice of sale of the bonds.

(2) Proceeds of sale of the bonds equal to the total par value of the bonds refunded shall be deposited at the fiscal agency mentioned in ORS 777.460 in conformity with the laws relating to deposits of funds with the fiscal agency or, at the option of the issuing port, pursuant to ORS 295.001 to 295.108, in a special trust account to be used solely for the payment of the principal of the outstanding refunding bonds and for no other purpose.
