(b) The ordinance shall require the designated county officer or department head to cause to be published, pursuant to Section 6063, a notice of intention to sell the seized and forfeited property. The resolution shall do all of the following:

(c) At the time and place fixed for the opening of the bids, the county officer or department head may accept the highest bid, written or oral. The county officer or department head shall not accept an oral bid unless it is made by a responsible person and exceeds the highest written proposal made by a responsible person by at least 5 percent. If the county officer or department head deems the action to be for the best public interest, he or she may reject any and all bids, either written or oral, and withdraw the property from sale.
