(A) Public Streets To Be Provided: A public street shall be provided for convenient access to all property within the subdivision. No private street or thoroughfare shall be permitted.
(B) Street Layout: The street layout of the subdivision shall be in general conformity with the official map of the most advantageous development of adjoining areas in the entire neighborhood. The streets shall be designed and located in relation to existing and planned streets, to topographical conditions and natural terrain features, such as streams and existing street growth, to public convenience and safety and in their appropriate relation to the proposed use of the land to be served by such streets.
(C) Other Requirements: All streets in a subdivision abutting a state or county highway shall meet all the requirements of the state or county regulations pertaining thereto as well as meeting the requirements of this title. Where such requirements are in conflict, the most restrictive shall apply.
(D) Parallel Streets Required: Where a subdivision borders on or contains a railroad or highway, the plan commission may require a street approximately parallel to and on each side of such railroad or highway, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for commercial or industrial purposes in appropriate districts. Such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
(E) Public Streets In Subdivisions: Whenever a tract to be subdivided embraces any part of a public street so designed in the comprehensive plan and official map, such part of such street shall be platted by the subdivision at the location and width indicated on the plan.
(F) Street Classification: Highway, major collector and local streets as classified in this subsection shall be as shown and designed in the official map.
1. Highway: Those state, county and village designated routes which provide continuity of travel and freedom from hazards and congestion necessary for interregional and city traffic movement.
2. Major Street: Those routes so designated by the city to be of importance in intra-city traffic movement and necessary to provide easy access to neighboring communities.
3. Collector Street: Those primary streets within the neighborhood unit which will act to collect traffic from minor streets for travel to major streets and highways.
4. Local Street: Those streets whose prime function is to give access to abutting property. They are not intended to carry heavy through traffic and are designed to discourage such movement.
5. Marginal Access Street: Those local streets which serve to control access to major thoroughfares and permit development of lands adjacent to high speed and high capacity highways. Their primary function is property access.
(G) Proposed Streets: Provision shall be made so that all proposed streets shall have a direct connection with or be continuous and in line with existing, planned, or platted streets with which they are to connect.
(H) Extension Of Streets: Where, in the opinion of the plan commission, it is necessary and desirable for the coordination of the layout of the subdivision with the existing or more advantageous future layout for development of adjacent land, to extend streets within the proposed subdivision, those streets shall be extended to the boundary lines of the proposed street construction, including grades, horizontal curves, vertical curves, and tangents, within the proposed subdivision, shall be in accordance with the "minimum standard for street design" in title 7, chapter 9 of this code.
(I) Street Names: New street names shall not duplicate the names of existing streets, but streets that are continuations of others already in existence shall bear the name of the existing street. All new streets shall be subject to the approval and guidelines of the plan commission.
(J) Cul-De-Sacs: Streets designed to have one end permanently closed shall terminate in a turnaround or tee terminus. A turnaround shall have a right of way of not less than one hundred forty feet (140') in diameter and a paved roadway turnaround of one hundred ten feet (110') in diameter. Cul-de-sac streets shall not exceed five hundred feet (500') in length as measured from center of the turnaround to the center of the intersection.
(K) Half Streets: Half streets shall be prohibited, except where essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations and where the plan commission finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided. Wherever a half street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.
(L) Intersections:
1. Streets shall be designed with no jogs or offsets less than one hundred twenty five feet (125'). Where streets intersect highways, their alignment shall be continuous.
2. Streets shall intersect in a manner to ensure safe traffic flow, preferably at right angles, but in no case shall two (2) streets intersect with an acute angle of less than sixty degrees (60°).
(M) Alleys:
1. Alleys shall not be permitted except that the plan commission may require alleys where other definite and assured provisions are not made for service access, such as off street loading, unloading, and parking, consistent with and adequate for the uses proposed.
2. The width of an alley, where required, shall be a thirty foot (30') right of way and pavement shall not be less than twenty feet (20').
3. Alley intersections and sharp changes in alley alignment shall be avoided, but, where necessary, corners may be modified to allow the vehicle types anticipated adequate space to perform turning maneuvers safely.
4. Dead-end alleys are prohibited.
(N) Reserve Strips: Controlling access to streets shall be prohibited except where their control is placed with the city under conditions approved by the plan commission. (Ord. 455, 4-21-1997)
