13-10-007-0001 Horizontal Alignment

Alignment shall be so arranged as to discourage through traffic on local streets. It shall also provide for through traffic around residential districts. Street alignment shall provide adequate access for police and fire protection, snow plows, and for other road maintenance equipment on local streets and good access on arterial and collector streets. The alignment shall provide for the continuation of arterial and collector streets to adjoining properties not yet developed. When topographic or other considerations make such continuance undesirable or impractical, these conditions may be modified. In either case, the access needs of the adjacent developed and undeveloped land must be addressed in the engineer’s design report. (Ord. 2017-22, Rep&ReEn, 07/05/2017)

13-10-007-0002 Other Design Considerations

A.    Tangents from centerline deflection shall be connected by a curve in accordance with Table 13-10-011-01.

B.    Reverse curves shall be separated by a minimum tangent length equal to the greater of 100 feet or a length sufficient to accommodate super-elevation and crown run-out, residential streets excepted.

C.    The maximum tangent length of residential local streets should be five hundred (500) feet to discourage high speeds. (Ord. 2017-22, Rep&ReEn, 07/05/2017)
