8-4-4: INSTALLATION OF CULVERT SPECIFICATIONS:
   A.   Elevation: Culverts shall be installed for each driveway crossing an open existing or proposed ditch. The culvert pipe shall be laid with the invert elevation thereof at the normal or proposed flow line of the ditch. (Ord. 88-240, 2-8-1988)
   B.   Size: Culvert size shall be of the diameter specified by the village but shall not be less than fifteen inches (15") internal diameter. (Ord. 88-240, 2-8-1988; amd. per correspondence dated 7-19-2006)
   C.   Side Extensions: The culvert shall extend a minimum of four feet (4') for each foot of depth on each side of the completed driveway and there shall be adequate side slope between the edge of the driveway and the end of the culvert pipe to prevent the entrance or obstruction of dirt or fill material. This requirement may be waived in instances where a concrete, stone or wood retaining wall is approved by the village.
   D.   Side Slope Protection: Culvert pipes shall be bedded in gravel. Where the invert elevation of the culvert pipe is three feet (3') or more, the side slope protection shall be of bituminous material or concrete. Pipe culverts shall consist of the following materials: corrugated metal pipe or ductile iron pipe.
   E.   Bent Or Damaged Ends: Bent or damaged ends of pipe culverts shall be repaired, straightened or trimmed prior to the bond refund. (Ord. 88-240, 2-8-1988)
   F.   Exception: In situations where the driveway approach is reconstructed and the installation of the new culvert to a village standard sized culvert may be impracticable due to the existing slope, pitch, driveway height or other considerations of the location in question, the village engineer may permit a replacement culvert of a size less than what is required under this section if and only if the integrity of the drainage ditch, the natural flow of water and other safety considerations are not compromised in the absence of a culvert that meets the specifications as specified in this section. (Ord. 2009-801, 12-15-2009)
