culverts type 1A. 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 the drainage area. In no case, however, shall a pipe
culvert of less than twelve inches in diameter be installed. 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 shall be

C. All areas disturbed in the course of this construction
shall be repaired to their original condition and all waterways shall be hand
raked and seeded as directed by the village administrator.
D. 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 feet horizontal per each vertical foot as
measured from the flow line or invert of the culvert to the edge of the
roadway.
E. The driveway surface shall be graded do that it meets the
edge of the existing street surface and drains toward the culvert at a minimum
slope of 0.50%. 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.
F. All work and materials used on the village right-of-way
shall be in accordance with the Standard Specifications for Road and Bridge
Construction as well as Exhibit A, attached to the ordinance codified in this
section and copies of which are on file in the office of the village
clerk.
G. 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 above the adjacent ground line may be constructed between the existing
road ditch and the property line when approved by the village
administrator.
H. Reflectors may be placed at the top of the slope in line
with the culvert. Reflectors shall not exceed four inches in any dimension and
shall not project more than twenty-four inches above the low point of the
driveway surface.

sidewalk at sidewalk grade causing neither a depression nor a hump in the
sidewalk without the express permission of the village administrator. (Ord.
