1. Pipe material shall conform to Illinois department of transportation standard specifications for road and bridge construction, latest edition, for pipe culverts type 1A.
2. The culvert shall be sized adequately to handle the drainage area to be served and shall be at least equal in diameter to the nearest crossroad culvert serving this drainage area. In no case, however, shall a pipe culvert of less than fifteen inches (15") in diameter be installed.
3. The culvert shall be placed in line with the existing road ditch horizontally and shall be placed at a vertical depth to provide the necessary drainage of the existing waterway. Minimum depth of cover over the top of the culvert pipe to the surface of the driveway shall be six inches (6"). If the existing ditch is not of sufficient depth to provide these minimum standards, the builder shall regrade the existing ditch as directed by the village superintendent of public works to provide the necessary drainageway.
4. Culvert pipe shall be of sufficient length to extend from toe of slope to toe of slope of the driveway cross section. In no case shall these slopes be steeper than three and one-half feet (31/2') horizontal per each vertical foot as measured from the flow line or invert of the culvert to the edge of the driveway. A channel bottom width of not less than one foot (1') shall be provided.
5. The driveway surface shall be graded so that it meets the edge of the existing street surface and drains towards the culvert at a minimum slope of 0.50 percent. The low point of the driveway shall not be closer to the street than the existing ditch, but in no case shall it be closer than four feet (4'). (Ord., 2-2-2009)
6. All driveways shall cross the existing or proposed sidewalk at sidewalk grade causing neither a depression nor a hump in the sidewalk without the express permission of the streets and public utilities committee. (Ord., 2-2-2009; amd. 2011 Code)

D. Obstructions Prohibited: No fences, posts, retaining walls, shrubs or curbs shall be constructed along driveways between the right of way line or property line and the street pavement, except a curb which does not project more than six inches (6") above the adjacent ground line may be constructed between the existing road ditch and the property line when approved by the village board of trustees.
E. Reflectors: Reflectors may be placed at the top of slope in line with the culvert. Reflectors shall not exceed four inches (4") in any dimension and shall not project more than twenty four inches (24") above the low point of the driveway surface. (Ord., 2-2-2009)
