The text
A.
Street Arrangement: The arrangement of streets in new subdivisions shall require the continuation of the existing streets in adjoining areas (or their proper protection where adjoining land is not subdivided), if considered necessary by the planning commission for meeting public requirements. The street arrangement may not cause unnecessary hardship to any owner of adjoining property when the owner plats the owner's land and seeks to provide convenient access to it.
B.
Minor Streets: Minor streets shall approach the major or collector streets at an angle of not less than eighty degrees (80°).
C.
Major and Collector Streets: Major and collector streets shall conform to the width designated on the major street plan where a subdivision falls in an area where a major street plan has been adopted. For territory where such street plan has not been completed at the time the subdivision preliminary plan is submitted to the planning commission, major or collector streets shall be provided as required by the planning commission with minimum widths of one hundred feet (100') for major streets and sixty-six feet (66') for collector streets.
D.
Minor Residential Streets: Minor residential streets shall have a minimum width of sixty feet (60'), except that cul-de-sacs (dead-end streets) or loop streets serving not more than ten (10) lots may have minimum widths of not less than fifty feet (50').
E.
Alleys: Alleys shall have a minimum width of twenty feet (20'). Alleys may be required in the rear of business lots but will not be accepted in residential blocks except under unusual conditions where such alleys are considered necessary by the planning commission.
F.
Cul-de-Sacs: Cul-de-sacs (turnarounds or dead-end streets) shall be used only where unusual conditions exist which make other designs undesirable. Cul-de-sacs are not desirable. Cul-de-sacs are not favorable to the city and will generally not be acceptable in subdivision plans. Each cul-de-sac must be terminated by a turnaround not less than one hundred feet (100') in diameter and cannot be a distance longer than four hundred feet (400') from the center of the intersection to the throat of the cul-de-sac. In the event that surface water drains into the cul-de-sac, necessary catch basins and drainage easements shall be provided.
G.
Easements: Easements for drainage through the property may be required by the city engineer, and easements of not less than ten feet (10') in width shall be provided if required for utilities or other purposes.
H.
Service Roads: Service roads paralleling major streets shall be required unless the planning commission approves double-frontage lots which may back onto major highways or collector streets as designated on the major street plan. Where lots back onto a major highway or collector street, a buffer planting strip of trees or shrubs shall be provided in a width of ten feet (10') or wider, but in no case less than ten feet (10').
I.
Blocks:
1.
Blocks may not exceed one thousand six hundred feet (1,600') in length. A dedicated walkway through the block may be required where access is necessary to a point designated by the planning commission. Such walkway shall be a minimum of four feet (4') in width but may be required to be wider where determined necessary by the planning commission. The applicant shall surface the full width of the walkway with a concrete surface, install a chain-link fence or its equal four feet (4') high on each side and the full length of each walkway, and provide, in accordance with the standards and rules and regulations, barriers at each walkway entrance to allow vehicles no wider than four feet (4').
2.
The width of blocks generally shall be sufficient to allow two (2) tiers of lots.
3.
Irregular shaped blocks, indented by cul-de-sacs, or containing interior spaces, will be acceptable when properly designed and fitted to the overall plat.
4.
Blocks intended for business or industrial use shall be designed specifically for such purposes with adequate space set aside for off-street parking and delivery facilities.
J.
Lots:
1.
The lot arrangement and design shall be such that lots will provide satisfactory and desirable sites for buildings and be properly related to topography and to existing and probable future requirements.
2.
All lots shown on the subdivision plan must conform to the minimum requirements of this title for the zone in which the subdivision is located, and to the minimum requirements of the city engineer and the state board of health for sewage disposal. The minimum width for any residential building lot shall be as required by this title. Where a public sewer is not available, the minimum area of such lot shall be no less than that approved in a letter to the planning commission by the board of health nor less than twenty thousand (20,000) square feet, whichever is greater.
3.
Each lot shall abut on a street dedicated by the recording of the subdivision or on an existing publicly dedicated street, or on a street which has become public by right of use and is more than twenty-six feet (26') wide. Interior lots abutting on more than one street shall be prohibited except where unusual conditions make other design undesirable.
4.
Corner lots shall have extra width sufficient for maintenance of required building lines on both streets.
5.
Side lines of lots shall be approximately at right angles, or radial to the street line.
6.
All remnants of lots below minimum size left over after subdividing of a larger tract must be added to adjacent lots, rather than allowed to remain as unusable parcels.
7.
Where the land covered by a subdivision includes two (2) or more parcels in separate ownership and the lot arrangement is such that a property ownership line divides one or more lots, the land in each lot so divided shall be transferred by deed to either single or joint ownership before approval of the final plat, and such transfer certified to the planning commission by the county recorder.
