The following standards of street design for both public and private streets shall be observed by the subdivider. If the average lot width of the lots served by the public street is in excess of 150 feet, the subdivider may request that the street width and grade conform to the rural standards for local streets. Rural streets do not require curb and gutter. The Planning Commission shall take into account future density of the area when determining whether rural standards are appropriate. The Planning Commission may consider the rural standards for streets where the average lot width is less than 150 feet if a finding is made that the area served by the road has rural qualities and will not support further development.
Street Category | Right-of-Way Minimum Width | Surfaced Minimum Width | Maximum Grade | Minimum Grade |
Arterial | 70 feet | 44 feet* | 6% | 0.4% |
Collector | 66 feet | 40 feet* | 8% | 0.4% |
Local | 60 feet | 36 feet* | 10% | 0.4% |
Local (Rural) | 50 feet | 22 feet* | 10% | 0.4% |

(A) Cul-de-sacs. The right-of-way radius shall measure 50 feet for single-family residential land use and 60 feet for all other land uses. In urban sections, the measurements provided in this division (A) shall be determined from the center of the cul-de-sac to gutter line of curb. In rural sections, such measurements shall be from center of cul-de-sac to edge of roadway surfacing.
(B) Street jogs. Streets jogs shall only be permitted subject to City Engineer approval.
(C) Street intersections. Streets shall intersect at right angles whenever possible and no intersection shall be at an angle of less than 60 degrees, unless otherwise approved by the City Engineer.
(D) Access to arterial and collector roadways. Where a proposed plat is adjacent to an arterial or collector roadway, spacing between access points shall not be to less than 660 feet (one-eighth mile) for collectors and 1,320 feet (one-fourth mile) for arterials unless otherwise approved by the City Engineer.
(E) Alleys. Alleys shall be prohibited in new residential areas unless permission is granted by the City Council.
