A.
Street Arrangement: The arrangement of streets in new developments shall make provision for the continuation of the existing streets in adjoining areas (or their proper protection where adjoining land is not developed) insofar as such may be deemed necessary by the planning commission for public requirements. The street arrangement shall be such as to cause no unnecessary hardship to owners of adjoining property when they plat their own land and seek to provide for 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 master street plan wherever a development falls in an area for which a master street plan has been adopted. For territory where such street plan has not been completed at the time the development 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 a minimum width of 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 (dead end streets) shall be used only where unusual conditions exist which make other designs undesirable. Each cul-de-sac must be terminated by a turnaround not less than one hundred feet (100') in diameter. If surface water drainage is into the turnaround due to the grade of the street, 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 where required for utilities or other purposes.
H.
Service Roads: Service roads paralleling major streets shall be required unless the planning commission approved double frontage lots which may back onto major highways or collector streets as designated on the master 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 a minimum of ten feet (10').
I.
Blocks: Blocks between streets shall 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 developer shall surface the full width of the walkway with a concrete surface.
