§ 98-82. Streets.

(a)

The width of major and secondary streets shall conform to widths designated on the official maps relative to streets or to such width as the planning commission may determine to be necessary to carry out the intended function of the master plan. The planning commission in making its determination shall require that streets conform to the following minimum right-of-way widths:

(1)

Expressway, 200 to 300 feet.

(2)

Parkway, 80 feet.

(3)

Arterial street, 80 feet.

(4)

Collector street, 66 feet.

(5)

Local street, 60 feet.

(6)

Cul-de-sac, 60 feet.

(7)

Marginal access street, 60 feet.

(8)

Alley, 20 feet.

(b)

The minimum width of streets whose ultimate length is in excess of 500 feet shall be 60 feet or greater. In cases where physical conditions appear to make the required minimum width of street impractical, the planning commission may modify this requirement.

(c)

Streets designed to have one end permanently closed, cul-de-sac, shall be not less than 60 feet in width and shall have a turning circle at the closed end with a right-of-way radius of not less than 50 feet and a pavement radius of not less than 40 feet. Such streets shall not extend for more than 450 feet from the centerline of the nearest intersection street. Where conformance to this provision results in lots of greater depth than 150 feet at the end of such cul-de-sac, the maximum length of such streets may be increased to 500 feet. In cases where physical conditions make this maximum length of cul-de-sac impractical the planning commission may modify this requirement in any proposal for subdividing lands where a street cannot be extended in any practical manner to intersect the cul-de-sac within 450 feet of its terminus because of the existing adjacent development. The property line at the intersection of the turning circle and the straight portion of the street require at or near the middle of the block a public way or easement of not less than ten feet in width for use by pedestrians and/or as an easement for public utilities; and easement may also be required at the end of a cul-de-sac. All easements for public utilities shall not be less than 12 feet wide, and an easement may be required for further expansion of utility lines. The planning commission may require the installation of landscaped islands in the closed end of the cul-de-sac.
