(1) Except for streets that are less than 150 feet long and streets that will be extended in the future, all streets that terminate shall be designed as a cul-de-sac bulb or an emergency vehicle turnaround.
(2) If a street will be extended in the future, a temporary easement shall be provided and an emergency vehicle turnaround shall be constructed.
(3) There shall be no cul-de-sacs more than 400 feet long from the centerline of the intersecting street to the radius point of the cul-de-sac bulb.
(4) Public accessways to provide safe circulation for pedestrians, bicyclists and emergency vehicles shall be required from a cul-de-sac or emergency vehicle turnaround longer than 150’ in length when measured from the centerline of the intersecting street to the radius point of the cul-de-sac or to the center point of the emergency vehicle turnaround.
(a) Physical conditions preclude development of the connecting street. Such conditions may include, but are not limited to, topography or likely impact to natural resource areas such as wetlands, ponds, streams, channels, rivers, lakes or upland wildlife habitat areas, or a resource on the National Wetland Inventory or under protection by state or federal law.
(b) Buildings or other existing development on the subject property or adjacent lands, including previously subdivided but vacant lots or parcels, physically preclude a connection now or in the future, considering the potential for redevelopment.
