Streets shall conform to at least all minimum requirements of the general specifications and typical cross-sections as set forth in this section and other conditions set forth by the governing body and the Macomb County Road Commission.
(a) Location and Arrangement.
(1) The proposed subdivision shall conform to the various elements of the Master Plan and shall be considered in relation to the existing and planned major thoroughfares and collector streets, and such part shall be platted in the location and width indicated on such plan insofar as possible.
(2) The street layout shall provide for the continuation of local or collector streets in the adjoining subdivisions or of the proper projection of streets when adjoining property is not subdivided, or conform to a plan for a neighborhood unit drawn up and adopted by the Commission.
(3) The street layout shall include minor streets so laid out that their use by through traffic shall be discouraged.
(4) Should a proposed subdivision border on or contain an existing or proposed major thoroughfare, the Commission may require marginal access streets, reverse frontage or such other treatment as may be necessary for adequate protection of residential properties and to afford separation and reduction of traffic hazards.
(5) Should a proposed subdivision border on or contain a railroad, expressway or other limited-access highway right of way, the Commission may require the location of a street approximately parallel to and on each side of such right of way at a distance suitable for the development of an appropriate use of the intervening land, such as for parks and Residential Districts. Such distances shall be determined with due consideration of the minimum distance required for approach grades to future grade separation.
(6) Half-streets shall be prohibited, except where absolutely essential to the reasonable development of the subdivision in conformity with the other requirements of these Regulations. Wherever there exists, adjacent to the tract to be subdivided, a dedicated or platted and recorded half-street, the other half shall be platted or the adjacent half-street shall be vacated.
(7) All entrances to subdivisions of eighty lots or more shall be boulevard streets designed in accordance with Macomb County Road Commission or Michigan Department of Highways and Transportation specifications, as applicable.
(b) Right-of-Way Widths. Street right of way widths shall conform to at least the following minimum requirements:
Street Type Right of Way Widths (ft.)
(1) Major thoroughfares In conformance with the
Major Thoroughfare Plan of
Clinton Township, as amended
(2) Collector streets 86
(3) Industrial service streets 70
(4) Multiple-family residential streets,
where platted 60
(5) Minor (single-family residential)
streets 60
(6) Marginal access streets 50
(7) Turn-around (loop) streets 120
(8) Alleys 20
(9) Cul-de-sac streets/turn-arounds:
A. Industrial 75 in radius
B. Residential and others 60 in radius
The maximum length for residential cul-de-sac streets shall generally be ten times the average width of lots on the street, but in no instance shall such streets exceed 600 feet in length. Maximum length for industrial and other cul-de-sac streets shall not exceed 500 feet, provided, however, that in such cases where it can be satisfactorily demonstrated that a greater length will not endanger the public health, safety or welfare, a greater length may be requested and submitted to the Planning Commission for its recommendation and to the governing body for its approval.
(c) Street Geometrics. Standards for maximum and minimum street grades, vertical and horizontal street curves and sight distances shall be established by ordinance or published rules of the governing body and shall, in no case, be less restrictive than the standards of the Macomb County Road Commission.
(d) Street Intersections. Streets shall be laid out so as to intersect as nearly as possible to ninety degrees. Curved streets, intersection with major thoroughfares and collector thoroughfares, shall do so with a tangent section of centerline fifty feet in length, measured from the right of way line of the major or collector thoroughfare, where said minor streets are on a curve with a radius of at least 400 feet, which tangent does not make a ninety degree intersection with the thoroughfare being intersected.
(e) Grading and Centerline Gradients. In accordance with the Land Development Regulations.
(f) Street Jogs. Street jogs with the centerline offsets of less than 125 feet shall be avoided.
(g) Truck Wells. Truck wells and receiving and shipping depots will be so located as to provide adequate vehicular movement on the site and shall not face directly onto a public right of way unless at least 100 feet from the right of way, and shall be subject to the review of the Macomb County Road Commission.
(Ord. 268. Passed 7-27-81.)
(h) Driveways. All driveway locations shall be subject to the review and approval of the Macomb County Department of Roads or the Michigan Department of Transportation, whichever shall have jurisdiction of the abutting highway or road, as applicable. Driveway locations for residential homes with detached garages or one-car attached garages shall not exceed twenty-eight feet in width at the roadway and twenty feet in width at the property line. Driveway locations for residential homes with two-car, three-car or larger attached garages shall not exceed thirty-five feet in width at the roadway and thirty feet in width at the property line.
