(a) Streets shall conform to the official plan as adopted and shall be accessible to existing or proposed parks, schools or other open public grounds shown on the official plan.
(b) If a tentative or suggested plan or plat for the area has been made by the Planning Commission, the street layout shall be in general conformance thereto.
(c) Arrangement of streets in new subdivisions shall make provision for the continuation of the principal existing streets in adjoining areas, or their proper projection where adjoining land is not subdivided, insofar as they may be deemed necessary for public requirements.
(d) Streets that are obviously in alignment with others already existing and named shall bear the names of the existing streets.
(e) The street and alley arrangement shall be such as not to cause a hardship to owners of adjoining property when they plat their own land and seek to provide for convenient access to it, and shall further the development of a coherent neighborhood street pattern in the vicinity of the subdivision.
(f) Where railroads or undesirable conditions exist, provision of buffer strips or other protective treatment shall be required to the extent and type as may be practicable.
(g) Frontage and high volume traffic-ways shall be provided with parallel service streets or such other means of minimizing access as may be appropriate to the conditions.
(h) Residential streets should be designed to discourage through traffic.
(i) The angle of intersection between minor streets and major streets should not vary by more than ten degrees from a right angle. All other streets should intersect each other as near to a right angle as possible and no intersection of streets at angles of less than sixty (60) degrees shall be permitted.
(j) Dedication of half-streets shall not be accepted unless exceptional circumstances are found by the Planning Commission or Council to justify the same. Where there exists a dedicated or platted half-street or alley adjacent to the tract being subdivided, the other half shall be platted if deemed necessary by the Planning Commission.
(k) The width of streets in new subdivisions shall be not less than the minimum width established herein.
(a) Alleys shall not be used in residential subdivisions except when deemed necessary by the Planning Commission to meet unusual conditions.
(b) Alleys are required in the rear of all commercial and industrial lots if no other provisions are made for adequate service access or for parking. The rights of way of such alleys shall not be less than twenty feet and dead-end alleys shall not be permitted.
The maximum length of Cul-de-sacs or courts shall be six-hundred (600) feet. The terminal shall be a circular area with a minimum right of way diameter of one-hundred (100) feet provided, however, that in unusual conditions the Planning Commission and Council may approve different arrangements.
Required rights-of-way for streets, alleys and easements shall have the following minimum width:
Minimum Width of Rights-of-Way | |
Primary streets | 100 feet |
Secondary streets | 80 feet |
Minor streets | 50-60 feet* |
Alleys | 20 feet |
Easements (on each side of property line) | 5 feet |
* The 50-foot minimum shall be acceptable only for cul-de-sacs, loop streets and short side streets which have no property frontage. | |
The maximum length of blocks shall generally be 1,320 feet. Those of over nine-hundred (900) feet may require a cross walkway at approximately the center.
(a) Where all or part of a subdivision is adjacent to or in the vicinity of a primary or secondary street the greater dimension of blocks shall be generally parallel to the primary or secondary streets to avoid unnecessary ingress and egress.
(b) A single tier of lots facing the minor street shall be the preferred practice where the proposed minor street is parallel to a major street. In other cases, the width of blocks shall generally be sufficient to allow two tiers of lots.
(c) Irregularly shaped blocks, including superblocks, indented by Cul-de-sacs and containing interior spaces, shall be encouraged when properly designed and fitted to the overall plan and when adequate provision for the maintenance of public areas is allowed for.
(d) Blocks intended for business and industrial use shall be designed specifically for such purposes with adequate space set aside for off-street parking and delivery facilities.
