The provisions of this chapter shall be the minimum township requirements for streets, roads and intersections. In the event that any other public agencies having jurisdiction shall adopt any statutes, ordinances, rules or regulations imposing additional, different or more stringent requirements, the terms of such statutes, ordinances, rules or regulations shall govern.
(A) Street location and arrangement. When a street or transportation plan has been adopted, subdivision streets shall substantially conform to the adopted plan.
(B) Minor street. Such streets shall be so arranged as to discourage their use by through traffic.
(C) Street continuation and extension. The arrangement of streets shall provide for the continuation of existing streets from adjoining areas into new subdivisions.
(D) Stub streets. Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall be extended to the boundary line of the tract to make provision for the future projection of streets into adjacent areas. Stub streets are subject to the requirements of division (I) below and § 156.041 of this chapter.
(E) Relation to topography. Streets shall be arranged in proper relation to topography so as to result in usable lots, safe streets and reasonable gradients.
(F) Alleys. Alleys may not be permitted in areas of detached single- or two-family residences unless approved by the County Road Commission or as private access easements under the township’s planned unit development zoning provisions. Dead-end alleys shall be prohibited.
(G) Marginal access street. Where a subdivision abuts or contains an arterial street, the Township Board may require:
(1) Marginal access streets approximately parallel to, and on each side of, the right-of-way; and
(2) Such other treatment as it deems reasonably necessary for the adequate protection of residential properties and to afford separation of through and local traffic such as planted buffer strips or the redesign of all or part if the street layout within the proposed plat.
(H) Dead-end streets and single access subdivision. Permanent dead-end streets are prohibited unless approved as a cul-de-sac by the Township Board and the County Road Commission. Single access subdivisions serving more than 75 residential lots are prohibited unless it can be shown to be temporary or that topography or subdivision shape precludes an additional access or indicates that a small increase in the number of lots served is warranted. Single-access commercial and industrial subdivisions shall be similarly discouraged. Approval of such shall take into consideration the length of looped utilities, alternative emergency access points, traffic volumes and the ability to adequately handle peak traffic flow with one access without negatively impacting adjoining streets and properties. As a general rule, commercial and industrial subdivisions that are expected to generate more than 300 vehicle trips in the peak hour will be required to have more than one access point to a paved collector or primary street.
(I) Cul-de-sac streets. All temporary and permanent dead-end streets must be provided with cul-de-sacs (turnarounds) at their termini. Temporary turnarounds shall be provided at the termini of streets where a future extension is contemplated. Temporary turnarounds need not be a part of the dedicated right-of-way; however, easements must be furnished to the County Road Commission for their use. Cul-de-sacs shall have a minimum radius of 60 feet for residential plats and 75 feet minimum in commercial and industrial plats.
(J) Half streets. Half streets are prohibited, except where unusual circumstances make it essential to the reasonable development of a tract in conformance with the provisions of this chapter and where satisfactory assurance for dedication of the remaining part of the street is provided. Whenever a tract to be subdivided borders on an existing half or partial street, the other part of the street shall be dedicated within such tract, according to the requirements of the County Road Commission.
(K) Private streets. Private streets and roads are prohibited.
(L) Street rights-of-way and roadway widths. Street and road rights-of-way and roadway widths shall conform to the Major Thoroughfare Plan of the township, if adopted and the rules of the County Road Commission and the State Department of State Highways and Transportation.
(M) Street alignment; horizontal alignment. Horizontal curves are to be used, as practical, at all changes in direction of the centerline of a continuous street. When street lines deflect from each other by more than ten degrees in alignment, the centerlines must be connected by a curve with a minimum radius of 350 feet of centerline radius. On local non-continuous residential streets, 90-degree curves are permissible.
(N) Street names. Street names may not duplicate any existing street name in the county, except where a new street is a continuation of an existing street of the same name. Any street name which is spelled differently, but sounds the same as an existing street name in the county is prohibited. All new streets shall be named as follows: streets with predominant north/south directions shall be named “Street” or “Roads”; streets with predominant east/west direction shall be named “Avenue”; meandering streets shall be named “Drive”, “Lane”, “Path” or “Trail”; and cul-de-sacs shall be named “Circle”, “Court”, “Way” or “Place”.
(O) Outlots. Outlots which are to become the right-of-way for future streets must be described as such on the plat.
