13.42.395: REQUIREMENTS RELATING TO IMPROVEMENTS:
   A.   Cost of construction of bridges and culverts at arterial streets and major thoroughfares may be borne by the city. The city may, but is not required to, participate in the cost of construction of bridges and culverts at collector streets where the required hydraulic cross section of the bridge or culvert is greater than forty (40) square feet, provided in any event that participation of the city is subject to the availability of funds. Cost to be borne by the city, if any, will be determined by the total cost of bridge or culvert divided by the square feet of cross section all multiplied by the square feet of required hydraulic cross section less forty (40) square feet.
   B.   Nothing in this section shall be construed to prevent an owner from bearing all costs if he so desires. Nothing in this section shall require the city to construct any bridge or culvert. (Ord. 1969, 2011)
