(A) All new or extended public and private dead end streets shall include a properly constructed turn around area at or near the end of the street.
(1) The design and the construction of a turn around area shall be suitable and appropriate for both of the following purposes:
(a) The turn around of large vehicles such as, but not limited to, fire engines, school busses, and snow removal equipment; and
(b) The orderly and efficient clearing of snow from the travel ways and the deposition by snowplows of all the snow that may be reasonably anticipated to accumulate at the end of a dead end street throughout an entire winter. For the portions of division (A) that follow, all references to directions of travel and the terms “right” and “left” are to be interpreted with regard to facing the end of travel.
(2) Within an area that is designated as a turn-around:
(a) The width of the travel way shall be not less than 24 feet;
(b) Junctions of the dead end street with branches of the turn-around shall have each corner rounded to provide a turning radius that forms a quarter circle of not less than a 50-foot radius tangent to the edges of the travel ways.
(c) Provisions for turn-arounds may be in any of the following forms.
1. A dead end street may have a turn-around that is formed by a single side branch near the end of the street. For this case, the area that is designated as a turn-around shall be in the form of a “T” that consists of a section of the dead end street and the side branch.
a. The centerline of the travel way of the side branch shall be located a minimum distance of 100 feet, but not more than 150 feet, from the end of the travel way of the dead end street.
b. The travel way of the side branch shall extend for a minimum distance of 100 feet from the centerline of the dead end street.
c. The area that is designated as the turn-around and that shall be constructed in accordance with this division (A)(2) shall include the side branch and that portion of the dead end street that extends from a minimum distance of 50 feet before the centerline of the side branch to a minimum distance of 100 feet past the centerline of the side branch.
d. The preferred location of a single side branch shall be on the right hand side of the dead end street for convenience of snow removal. A single side branch may be located on the left hand side of the dead end street only under special circumstances and only upon the concurrence in writing of the Town Council.
2. A dead end street may have a turn-around that is formed by double side branches near the end of the street. For this case, the area that is designated as a turn-around shall be in the form of a “+” that consists of a section of the dead end street and side branches directly on opposite sides of the dead end street.
a. The centerline of the travel ways of the side branches shall be located a minimum distance of 50 feet, but not more than 100 feet, from the end of the travel way of the dead end street.
b. The travel ways of the side branches shall extend for a minimum distance of 100 feet from the centerline of the dead end street.
c. The area that is designated as the turn-around and that shall be constructed in accordance with this division (A)(2) shall include the side branches and that portion of the dead end street that extends from a minimum distance of 50 feet before the centerline of the side branches to a minimum distance of 50 feet past the centerline of the side branches.
3. A street that may otherwise be a dead end street may terminate in a loop or circular travel way that may have an irregular shape.
a. Curves shall have a minimum centerline turning radius of not less than 150 feet.
b. The connection of a loop or circular travel way with the dead end street must include a straight section that is perpendicular to the dead end street on the right hand side of the dead end street. The straight section and the associated portion of the dead end street shall be designated as a turn-around and shall be constructed to the same dimensions as in divisions (A)(2)(b)1.b. and (A)(2)(b)1.c. above.
c. Smaller cul-de-sacs shall not be allowed.
(B) Driveway access from turn-arounds shall not interfere with or otherwise disrupt the orderly and efficient clearing of snow from the travel ways. In order to provide for driveway access, the design of a turn-around may be augmented with additional space for the deposition of snow. Locations of driveway access shall be determined only upon the concurrence in writing of the Town Council.
