(a)   The storm drainage system shall include roadside ditches, culverts, inlets, and retention/detention facilities.  All storm drainage facilities shall be designed to adequately handle the surface runoff from a design storm of five (5) year intensity for residential development with the tributary area assumed to be fully developed.  All storm drainage shall be discharged into natural watercourses or storm sewers, if available.  If, under the above design conditions, the roadside ditch will flow at a depth greater than one (1) foot, storm sewers should be installed from that point of discharge.
   (b)   All culverts shall be of reinforced concrete pipe or reinforced concrete rectangular in cross section, and, in either case provided with headwalls and/or slope protection sufficient to prevent erosions of the slopes and channel bed.
   (c)   No part of the storm drainage system, which includes footer drains, shall be discharged into the sanitary sewer system.
   (d)   Storm sewer facilities shall comply with the Ohio EPA General Stormwater NPDES Permit and the Village's Storm Water Management Ordinance and Erosion and Sediment Control Ordinance.  (Ord. 2012-21.  Passed 7-11-12.)
