A. General Street Design:
1. The design of all streets shall be considered in their relation to existing and planned streets, to reasonable circulation of traffic, to topographical conditions, to runoff of storm water, and to the proposed uses of the area to be served.
2. Where new streets extend existing adjoining streets, their projections shall be at the same or greater width, but in no case less than the minimum required width.
3. Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall make provisions for the proper projection of streets. When a new subdivision adjoins unsubdivided land susceptible to being subdivided, then the new streets shall be carried to the boundaries of such unsubdivided land.
B. Street Width And Grades:
1. The planning commission may require the subdivider to conform to urban section standards of subsection D of this section if the average lot width in the proposed subdivision is less than one hundred fifty feet (150') measured at the street setback line. If the average lot width is in excess of one hundred fifty feet (150'), the subdivider may conform to the rural section standards of subsection D of this section.
2. Unless necessitated by exceptional topography subject to the approval of the planning commission, the maximum centerline grade of any street or public way shall not exceed the following:
a. Arterial streets: Six percent (6%).
b. Collector streets: Eight percent (8%).
c. Local streets, alleys and frontage streets: Ten percent (10%).
d. Pedestrianways: Eight percent (8%) unless steps of acceptable design are provided. The grade of any street shall in no case exceed ten percent (10%) or be less than one-half of one percent (0.5%).
e. Street grades shall be established wherever practicable so as to avoid excessive grading, the promiscuous removal of ground cover and tree growth, and general level of topography.
C. Street Jogs: Street jogs with centerline offsets of less than one hundred twenty five feet (125') shall be avoided.
D. Street Intersections: Insofar as practical, streets shall intersect at right angles, and no intersection shall be at an angle less than sixty degrees (60°). It must be evidenced that safe and efficient traffic flow is encouraged.

Arterial street 4 lane divided | 150 feet | 150 feet | Dual 24 feet; 10 foot outside shoulders; 4 foot inside shoulders (60 foot median) |

Collector street | 70 feet | 70 feet | 22 feet; 8 foot outside shoulders |
Local streets | 66 feet | 66 feet | 20 feet; 6 foot outside shoulders |
E. Cul-De-Sacs: Maximum length of permanent cul-de-sac streets shall be five hundred feet (500') measured along the centerline from the intersection of origin to end of right of way. Each cul-de- sac shall be provided at the closed end with a turnaround having a minimum outside roadway diameter of eighty feet (80') and a minimum street property line diameter of one hundred feet (100').
F. Half Streets: Half streets shall be prohibited except where the board of trustees finds it to be practicable to require the dedication of the other half when the adjoining property is subdivided.
G. Street Names: Proposed streets obviously in alignment with existing and named streets shall bear the names of such existing streets. In no case shall the name of the proposed street not in alignment duplicate existing street names, including phonetical similarities.
H. Private Streets: Public improvements shall not be approved for any private streets.
I. Access To Arterial Streets And Highways: Where a proposed plat is adjacent to an arterial street, spacing between access points to such thoroughfares of less than six hundred sixty feet (660') and in commercial districts, four hundred feet (400'), shall be avoided except where impractical or impossible due to existing property divisions or topography.
J. Street Curvature: When a continuous street centerline deflects at any one point by more than ten degrees (10°), a circular curve shall be introduced having a radius of curvature on said centerline of not less than the following:
1. Arterial Streets And Highways: Five hundred feet (500').
2. Collector Streets: Three hundred feet (300').
3. Local Streets: Two hundred feet (200').
K. Hardship To Owners Of Adjoining Property: The street arrangements shall not be such as to cause hardship to owners of adjoining property in platting their own land and providing convenient access to it.
L. Corners: Curb lines at street intersections shall be rounded at a radius of not less than ten feet (10').
M. Reverse Curves: A tangent at least one hundred feet (100') long shall be required between curves on arterial and collector streets.
N. Alleys: Alleys shall be prohibited in residential areas unless special permission is granted by the board of trustees for their provision. Alley intersections and sharp changes in alignment shall be avoided, but where necessary, corners shall be cut off sufficiently to permit safe vehicular movement. Dead end alleys shall be avoided, but if unavoidable, shall be provided with adequate turnaround facilities at the dead end. (1999 Code § 10.02)
O. Maintenance: Streets included in approved subdivisions, except designated state, federal or county roads, shall be maintained by the village unless other written arrangements are made prior to final plat approval. (1999 Code § 10.02; amd. 2005 Code)
