A field entrance or a utility structure driveway may be surfaced with stabilized gravel or with sod over a stable base and may be uncurbed, as determined by the Department of Public Works.
(Ord. 2008-01, passed 5-12-2008)
The surface of a paved driveway, excluding right-turn lanes, shall be concrete, bituminous or equivalent surfacing material. The thickness of the surface and the base to be used shall be sufficient to provide the bearing capacity needed to carry the proposed traffic loads. A two and one-half inch, 250 pounds per square yard, bituminous mix on eight inches of compacted gravel, eight inches of unreinforced concrete or equivalent surfacing material which meets current Michigan Department of Transportation standard specifications for street construction is acceptable for normal driveway traffic loads over stable soil.
(Ord. 2008-01, passed 5-12-2008)
(A) The pavement of a right-turn lane and accompanying tapers shall match the street pavement, unless the Department of Public Works permits the use of an equivalent pavement.
(B) The cross slope of a right-turn lane and tapers shall be:
(1) A continuation of the cross slope of the street, if the street is curbed; and
(2) Equal to the shoulder slope, if the street is uncurbed.
(Ord. 2008-01, passed 5-12-2008)
(A) The surface of the shoulder adjacent to a right-turn lane and tapers shall be of the same material as the street shoulder and conform to the current Michigan Department of Transportation standard specifications for street construction.
(B) If the distance between two paved commercial driveways serving the same property is less than 100 feet, measured between adjacent ends of the curb endings, the applicant shall pave the shoulder between the driveways.
(Ord. 2008-01, passed 5-12-2008)
(A) The driveway curb shall either match the existing street curb or shall conform to the current Michigan Department of Transportation standards for curb and gutter.
(B) The driveway curb height shall be constant if there is no existing or proposed sidewalk or if an inclined sidewalk is permitted by the Department of Public Works.
(C) The driveway curb height shall be tapered to zero height at the sidewalk if the driveway grade meets the grade of an existing or proposed sidewalk.
(Ord. 2008-01, passed 5-12-2008)
(A) A driveway shall be constructed so that it does not adversely affect the street drainage. The drainage and the stability of the street subgrade shall not be altered by driveway construction or roadside development.
(B) Drainage from adjacent parking or storage areas on private property in excess of existing drainage shall not be discharged into the street drainage system.
(C) Culvert pipe shall be of a size adequate to carry the anticipated natural flow of the ditch. The culvert shall be no smaller than the nearest upstream culvert nor less than 12 inches inside diameter. A culvert, catch basin, drainage channel and other drainage structure required within the street right-of-way shall be manufactured or constructed and installed in accordance with the current Michigan Department of Transportation Standard Specifications for Highway Construction. The minimum length of the culvert may be determined as the sum of the distance between driveway edges, measured along the ditch line, plus the distances needed to accommodate an embankment slope not to exceed one foot vertical for six feet horizontal on both sides of the driveway.
