(A) All proposed subdivisions shall conform to the thoroughfare plan contained in the city comprehensive plan as is now or may be set forth hereafter. Whenever any tract to be subdivided abuts or is adjacent to any street shown in the thoroughfare plan, that part of the public right-of-way for that street shall be dedicated and platted by the subdivider in the location and with the right-of-way width as indicated on the thoroughfare plan and the subdivider shall construct the street improvements. The arrangement of streets in the subdivision shall provide for the continuation and extension of existing principal streets in surrounding areas or conform to a plan of the neighborhood approved and adopted by the Plan Commission.
(B) The arrangement, character, extent, width, grade and location of all streets shall be correlated to existing and planned streets, existing topography, public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets.
(C) Local streets shall be laid out so that their use by "cut-through" traffic will be discouraged, but in such a manner that inter-connectedness between neighborhoods and to collector and arterial streets is created.
(D) Where a subdivision abuts or contains an existing or proposed arterial or major collector street as indicated on the thoroughfare plan, the Plan Commission may require:
(1) Marginal access streets;
(2) Reverse frontage with screen planting contained in a "no-access" easement along the rear property line having a minimum width of ten feet;
(3) Deep lots with rear service ways; or
(4) Such other treatments as may be necessary for adequate protection of properties and to afford separation of through and local traffic.
(E) Where a subdivision borders on or contains an existing or proposed arterial, a railroad right-of-way or limited access highway right-of-way, the Plan Commission may require a street approximately parallel with the right-of-way, at a distance from the right-of-way. The land between the street and the right-of-way will have sufficient depth to provide an adequate buffer between the street and the subdivision uses. Such distances shall be determined with due regard for the requirements of approach grades and future grade separations. The Plan Commission may require that the intervening land strips be dedicated to the city, or if located in the unincorporated jurisdictional area, to the county. The land strip shall be maintained by the involved governmental unit from the date of dedication.
(F) Whenever an existing half-street or half-alley is adjacent to a tract to be subdivided, the other half of the street or alley shall be platted within the tract. Whenever the thoroughfare follows a property line, half of the right-of-way of the thoroughfare shall be platted within the tract. Half-streets and half-alleys shall be prohibited otherwise.
(G) Wherever a dedication or platted portion of a street or alley exists adjacent to the proposed subdivision, an extension of the remainder of the street or alley to the right of way width, indicated on the thoroughfare plan, shall be platted within the proposed subdivision.
(H) In designing and approving subdivision streets, the following factors shall receive consideration:
(1) Accessibility for emergency vehicles and school buses;
(2) Safety for both vehicular and pedestrian traffic through the use of roundabouts, curvilinear features, boulevards and other traffic calming design elements;
(3) Efficiency of services for all users;
(4) Livability or amenities as affected by traffic elements in the circulation system;
(5) Economy of both construction and use of land; and
(6) Improving connectivity and dispersion of traffic on local, collector and arterial streets.
