Exceptions:

If the two-way road serves a minor subdivision (subdivided into four parcels or fewer) in compliance of Chapter 25 and when permitted in a subdivision's conditions of approval and approved by the appropriate county departments, as identified in the subdivision's conditions of approval, the subdivision may have a two-way road of not less than twelve feet (12') with two-foot (2') shoulders on each side and turnouts and turnarounds. Spacing of the turnarounds and turnouts shall be as set forth in the subdivision's conditions of approval.

a.

If the minor subdivision's conditions of approval do not set forth spacing requirements, then turnarounds shall be at a minimum interval of one thousand three hundred and twenty feet (1,320'). Turnouts shall be a minimum of five hundred feet (500') and shall not be located on the inside of horizontal curves without approval from the fire code official.

b.

The fire code official is authorized to request the installation of turnarounds and turnouts as part of a development approval at locations necessary to provide two- way traffic flow.
