Streets shall conform to, at least, all minimum requirements of the general specifications of this article of this chapter and shall conform to the right of standards of the City and the County Planning Commission.
(A) Layout. The layout of a proposed street shall provide for the continuation of existing streets in surrounding areas and/or shall conform to a plan for the neighborhood approved by the Planning Commission in codes where topographical or other natural or unnatural conditions preclude the continuation of existing streets. Such streets shall be of width as great as that of the street so extended. Local residential streets shall be laid out as to discourage their use by through traffic.
(B) Major thoroughfares. When a subdivision abuts or contains 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.
(C) Private streets and alleys. Private streets and alleys shall be prohibited unless located at the rear of commercial or industrial uses.
(D) Access to property. Each residential lot within a subdivision shall be provided with a satisfactory means of access. Building permits shall not be issued for the construction of buildings which do not have access on a public street. There shall be no reserve strips controlling access to a street except where the control of such streets is definitely dedicated to the city.
(E) Intersections. Intersecting streets shall be laid out so that the intersection angle is as nearly possible to 90°. Streets converging at one point shall be reduced to the least practicable number.
(F) Dead-end streets. When adjoining and not platted, the arrangements of streets in new subdivisions shall be extended to the boundary lines of the tract to make provision for the future projection of streets into adjacent areas. A one-foot public reserve may be required to be placed between stub streets and subdivision boundaries.
(G) Street names. Street names shall not be permitted which might cause confusion for purposes of assessing mail delivery, or locating by the public with names of existing streets in or near the city. Streets that will be continuations of existing streets shall be called by the same names of such existing streets.
(H) Building lines and setback lines. Building lines and setback lines shall conform to the requirements of the Zoning Code.
(I) Street alignment.
(1) (a) Minimum horizontal centerline radii of curvature shall be:
1. Major thoroughfares, 700 feet radius.
2. Collector streets, 450 feet radius.
(b) A minimum 50 feet tangent shall be introduced between reverse curves on local streets, 100 hundred feet on major thoroughfares, except that upon recommendation of the City Engineer an exception may be granted by the City Council.
(2) Visibility requirements.
(a) Minimum vertical visibility (measured from 4½ feet eye level to 18 inch taillight) shall be:
1. Five hundred feet on major thoroughfares.
2. Three hundred feet on secondary streets or collection streets.
3. Two hundred feet on local streets.
4. One hundred feet on local streets.
(3) Street jogs. Street jogs with centerline offsets of less than 150 feet shall be avoided.
(4) Intersection. Curved streets intersecting with major or secondary thoroughfares shall do so with a tangent section of centerline 100 feet in length measured from the right-of-way of the major collection thoroughfares and at 90°, except that upon recommendation of the City Engineer, an exception may be granted by the City Council.
(J) Surface drainage. Adequate and safe disposal of all yard drainage shall be provided in accordance with specifications prescribed by the City Engineer.
(K) Street right-of-way widths.
(1) Street right-of-way widths shall conform to, at least, the following minimum requirements:
Rights-of-Way | Feet |
Rights-of-Way | Feet |
Major thoroughfares | 120 |
Collector streets | 86 |
Industrial, commercial and multi-family | 86 |
Service streets | 60 |
Local residential streets | 60 |
Marginal access streets | 34 |
Alleys | 20 |
Turn-around (loop) streets | 120 |
Cul-de-sac streets | 60, radius |
(2) Maximum length of residential and industrial cul-de-sac shall not exceed 600 feet and shall end in a circle 120 feet in diameter.
