Sidewalks-Sidewalk construction shall be in accordance with section 803 of the MDOT Specification.
1. Location and Width
The sidewalk shall be 5’ in width and the outside edge located 1’ from the right-of-way line.
Sidewalk elevations shall be determined by the existing elevation of the road. Construct the
property side of the sidewalk at 6” above the centerline of the road.
- Grade
- Sidewalks are to have a traverse grade of 2% (1/4” per foot) draining toward the road. The maximum allowed longitudinal grade shall be 5%. This grade shall not be exceeded unless the road grade is of a steeper grade, in which case the longitudinal sidewalk grade shall not exceed the road grade.
- Surface Material Requirements and Specifications
Sidewalks shall meet the following aggregate base course requirements and shall be hard surfaced
with concrete materials as listed below:
| (a) Aggr | egate Base Course Material Gradation Thickness | - M.D.O.T. Spec. 302 - 22A - M.D.O.T. 902-1 Minimum 25% crushed - 6” compacted in place |
| (b) Concrete | Surface Material Thickness | - M.D.O.T. Spec. 802 - 5 sack mix design - 4” - 6” through residential driveways - 8” through industrial driveways |
| 4. Surface Drainage |
All existing drainage shall be accommodated with the construction of new sidewalk. All connections to existing storm sewer systems shall be approved by the Ottawa County Drain Commission.
Non-Motorized Facility Construction Standards Within Right-of-way in Georgetown Township as of November 15, 2004
Any non-motorized facility constructed within the right-of-way in Georgetown Township must receive Ottawa County Road Commission approval for alignment and grade and Township Board approval prior to beginning construction. It is the responsibility of the property owner that the construction meets Ottawa County Road Commission specifications. If the construction does not meet the specifications, the possibility exists that the construction would have to be removed and replaced according to the correct specifications.
Non-motorized facility construction shall be in accordance with section 806 of the MDOT Specifications.
- Location and Width The non-motorized facility shall be 8’ in width and the outside edge located 1’ from the right-of-way line. Non-motorized facility elevations shall be determined by the existing elevation of the road. Construct the property side of the non-motorized facility at 6” above the centerline of the road.
- Grade Non-motorized facilities are to have a traverse grade of 2% (1/4” per foot) draining toward the road. The maximum allowed longitudinal grade shall be 5%. This grad shall not be exceeded, unless the road grade is of a steeper grade, in which case the longitudinal non-motorized facility grade shall not exceed the road grade.
- Vertical and Horizontal Curves Non-motorized facilities shall be designed in accordance with the requirements of the AASHTO-Guide for Development of New Bicycle Facilities (1991 or current edition).
- Surface Material Requirements and Specifications Non-motorized facilities shall meet the following aggregate base course requirements and shall be hard surfaced with either bituminous or concrete materials as listed below:
- Aggregate Base Course - M.D.O.T. Spec. 302 Material - 22A Gradation - M.D.O.T. 902-1 Minimum 25% crushed Thickness - 6” compacted in place
- Bituminous Surface - M.D.O.T. Spec. 500 Material - Bituminous Mixture 13A Leveling
- - Bituminous Mixture 36A Surface Thickness - 2 ½” 275#/Sq. Yd. Min. Asphalt Cement - Performance Grade 58-28 Temperature & Seasonal Limitations Table 502.03.J
- Concrete Surface - M.D.O.T. Spec. 802 Material - 5 sack mix design Thickness - 4”
- -6” through residential driveways
- -8” through industrial driveways
- Surface Drainage All existing drainage shall be accommodated with the construction of non-motorized facilities. All connections to existing storm sewer systems shall be approved by the Ottawa County Drain Commission.
