§ 1248.04 STREET LAYOUTS.
   (a)   Circulation. The street pattern shall provide ease of circulation within the subdivision as well as convenient access to adjoining streets, thoroughfares or unsubdivided lands as may be required by the Planning Commission. Minor residential streets should be so planned as to discourage their use by nonlocal traffic.
   (b)   Consistency with adjoining streets. The arrangement of streets shall make provisions for the continuation of the principal existing or proposed streets in adjoining areas, or their proper projection where adjoining land is not subdivided, insofar as they are necessary for public requirements.
   (c)   Allowance for hardship to adjoining owners. The street layout shall be designed so as not to cause a hardship to owners of adjacent property when they plat their own land and seek to provide for convenient access to it. The Planning Commission may require land to be reserved for future street purposes to be developed by an adjacent land owner at a later date.
   (d)   Extensions to subdivision boundary lines. Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions or unless, in the opinion of the Planning Commission, such extension is not necessary or desirable for the coordination of the layout of the subdivision with the existing layout or the most suitable layout of adjacent tracts.
   (e)   Intersections. Proposed streets shall intersect one another as nearly at right angles as topography and other limiting factors of good design permit.
   (f)   Street jogs. Street jogs with centerline offsets at intersections shall not be allowed unless the distance between such centerline offsets is at least 200 feet on local and collector streets, 300 feet on secondary thoroughfares and 500 feet on primary thoroughfares.
   (g)   Cul-de-sacs. Cul-de-sacs may be approved where necessitated by topography or where, in the opinion of the Planning Commission, they are appropriate for the type of development contemplated. Turnarounds of the circular type shall be required. Except in unusual circumstances, the Commission shall not approve a cul-de-sac with a length greater than 700 feet, and in no case shall such length be greater than 800 feet.
   (h)   Temporary dead-end streets. Except as otherwise provided in these Subdivision Regulations, temporary dead-end streets may be approved where necessitated by the layout of the subdivision or staging of development, provided that temporary paved turnarounds shall be constructed at the end of such streets in cases where more than eight lots front on such streets. The widths of rights-of-way or temporary easements shall be the same as that required for permanent turnarounds. The extra right-of-way in excess of the street right-of-way shall be vacated upon extension of the temporary street, and the reconditioning of such street and all surface improvements and front yards concerned shall be carried out at the expense of the subdivider responsible for the extension of such temporary dead- end street.
   (I)   Half streets. Dedication of half streets shall not be permitted, except in special situations which are in the public interest. Where there exists a dedicated or platted half street adjacent to the tract being subdivided, the other half shall be platted if, in the opinion of the Planning Commission, it is necessary to promote proper development.
   (j)   Private streets. Except in unusual conditions when held desirable by the Planning Commission, or in cases permitted in accordance with the Zoning Code, private streets will not be approved.
