(a) Cul-de-sac streets shall
generally not exceed six hundred feet (600') in length. The length shall be measured from
the end of the cul-de-sac to the closest intersection which provides a means of egress
from the subdivision, either directly or indirectly. Where the agent determines that the
topography, property configuration or other physical constraints are such that a
cul-de-sac of greater length is required or desirable for the effective and efficient
development of the property, the agent may authorize cul-de-sacs which exceed six hundred
feet (600') in length. In such cases, the cul-de-sac street shall generally be designed
with a landscaped median which divides the cul-de-sac street into (2) two distinct and
separate lanes. Such street may, however, be continuously undivided for the final six
hundred feet (600') measured from the end of the turnaround. Median breaks shall be
provided at street intersections and at other appropriate locations along the street to
ensure good traffic circulation and the delivery of emergency services. In general, this
means that median breaks should occur approximately at three hundred foot (300')
intervals. In consultation with the department of
fire and life safety, the agent may waive or
modify the median requirement if it is determined
that such a design will not aid emergency access and operations.
(b)
Cul-de-sac streets shall be terminated by a turnaround
having a minimum pavement radius of forty-five feet (45')
or such other design as may be approved by the department of
transportation with the concurrence of the department of fire and life
safety.
