(A) Where natural drainage channels intersect any street right-of-way, it shall be the responsibility of the sub-divider to have satisfactory bridges and/or culverts constructed. The drainage channel is then to be maintained by the property owner and not modified, filled or diverted without the consent of the City Manager.
(B) Where culverts are required, minimum requirements shall be observed as follows: All culverts shall extend for an adequate distance to accommodate the required roadway embankment slopes. The cover over the culvert and its capacity shall be determined by the sub-divider’s professional engineer and approved by the City Manager. The minimum diameter of the culvert pipe shall be 12 inches. Depending on the existing drainage conditions, head walls may be required. Where driveway culverts are wholly or partially in the street right-of-way, they shall have a minimum length of 20 feet and minimum diameter of 12 inches. The driveway culverts shall be placed so as to maintain the flow lines of the ditch or gutter.
