1109.04  STORM DRAINAGE.
   Adequate provisions shall be made for the disposal of storm water in accordance with the requirements of the City Engineer and Planning Commission.
   (a)   General Design.
      (1)    Preferred runoff pattern. The design of streets for storm drainage shall be such that runoff from roofs, driveways and other impervious areas, will be toward the street, collected along curbs and gutters of the street in short runs (maximum 400 feet), and then be directed from the street surface into storm sewers or natural watercourses.
      (2)    Sewers.  Storm sewers shall ordinarily be required and the design must meet the requirements of the City Engineer. The minimum pipe size will be twelve inches.
      (3)    Location. Storm drains shall be located according to the specifications of the City Engineer.
      (4)    Manholes.  Manholes shall be a maximum of 300 feet apart in pipe size up to twenty-four inches; and a maximum of 450 feet apart on pipes larger than twenty-four inches. The design must be approved by the City Engineer.
   (b)   Open Water Courses. The use of open water courses shall be determined by the Planning Commission on the advice of the City Engineer.
      (1)    Where a subdivision is traversed by a water course, channel, stream, or creek, the subdivider shall dedicate a right-of-way, or provide sufficient easement, construction, or both, to dispose of surface or storm waters. Such improvement shall be in accordance with the requirements of the City Engineer.
         A.   Broad, shallow courses shall be created to prevent steep banks, erosion, and to allow for motorized equipment to work the channel or water course.
         B.   The Planning Commission shall require seeding, sodding, planting, riprap or other measures which will add to the beauty of the area and prevent scouring.
