Purchases of supplies and equipment shall be by bid procedures pursuant to sections 3.16.160 and 3.16.170. Bidding may be dispensed with only when an emergency requires that an order be placed with the nearest available source of supply, or when the amount involved is less than fifteen thousand dollars, or when the commodity can be obtained from only one vendor, or when the item to be purchased is purchased surplus from another public agency, or for used equipment not readily available on the general used equipment market.
