Streets shall conform to at least all minimum requirements of the general specifications and typical cross-sections as set forth in this subchapter and other conditions set forth by the City 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 the plan.
(2) The street layout shall provide for continuation of 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 Planning 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 Planning 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) (a) Should a proposed subdivision border on or contain a railroad, expressway, or other limited access highway right-of-way, the Planning Commission may require the location of a street approximately parallel to and on each side of the right-of-way at a distance suitable for the development of an appropriate use of the intervening land such as for parks in residential districts.
(b) The 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, and where the Planning Commission finds it will be practicable to require the dedication of the other half when the adjoining property is developed. Wherever there exists adjacent to the tract to be subdivided, a dedicated or platted and recorded half street, the other half shall be platted.
(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 (feet) |
Street Type | Right-of-Way Widths (feet) |
Major thoroughfare | 100 |
Collector streets | 80 |
Industrial | 60 |
Multiple-family residential streets, where platted | 60 |
Minor single-family residential streets | 60 |
Marginal access streets | 34 |
Turn-around (Loop) street | 120 |
Alley | 20 |
Cul-de-sac streets—Turnarounds | |
1. Industrial | 75 (radius) |
2. Residential and others | 60 (radius) |
Maximum length for residential cul-de-sac streets shall generally be 500 feet. Maximum length for industrial and other cul-de-sac streets may exceed 500 feet subject to the approval of the Planning Commission. | |
(C) Street grades. For adequate drainage, the minimum street grade shall not be less than 0.5%. The maximum street grade shall be 6% except that the Planning Commission may make an exception to this standard on the recommendation of the Engineer.
(D) Street geometries. 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 City Commission and shall in no case be less restrictive than the standards of the county road Commission.
(E) Street intersections. Streets shall be laid out so as to intersect as nearly as possible to 90 degrees. Curved streets, intersecting with major thoroughfares and collector thoroughfares shall do so with a tangent section of centerline 50 feet in length, measured from the right-of-way line of the major or collector thoroughfare.
(F) Grading and centerline gradients. Per plans and profiles approved by the Engineer.
(G) Street jogs. Street jogs with centerline offsets of less than 125 feet shall be avoided.
