Where natural drainage channels intersect any street right of way, it shall be the responsibility of the subdivider and/or developer to have satisfactory bridges and/or culverts constructed. Where culverts are required, minimum requirements shall be observed as follows:
(a) The length of a culvert, the cover over the culvert, and its capacity shall be determined by the City Engineer. The minimum diameter of the culvert pipe shall be twelve inches. Depending on the existing drainage conditions, head walls may be required.
(b) Where driveway culverts are wholly or partially in the street right of way, they shall have a minimum length of twenty feet and a minimum diameter of twelve inches. The driveway culverts shall be laid so as to maintain the flow lines of the ditch or gutter.
