§ 48-121. Streets and roads.

(a)

The subdivider shall dedicate land and improve public streets in any new subdivision or land division in order to provide public access to all lots created. The arrangement, design and location of all streets and roads shall conform to all applicable plans, official maps or highway width maps adopted by the applicable units of local government and the county and give due regard to other existing and planned streets, other improvements, proposed land uses and natural features of the property in question as well as adjacent lands.

(b)

The arrangement of streets and roads in a new subdivision shall be designed to allow for continuation of existing streets into adjoining areas.

(c)

Where adjoining, developable lands are not subdivided or developed, the arrangement of streets in the proposed development shall allow for the proper projection of streets or roads to the boundary of the proposed development.

(1)

Reserve strips controlling access to streets shall be prohibited except where their control is placed with the town under conditions approved by the county planning agency.

(2)

Dead-end streets other than culs-de-sac shall only be permitted when authorized by the county planner. When such dead-ends are permitted on a temporary basis, and exceed 200 feet or two lot widths, a temporary turnaround shall be provided, and appropriate arrangements made for those portions of temporary turnarounds outside the right-of-way to revert to the abutting property owners upon extension of the street.

(d)

All street right-of-way widths, radii or curvature and grades shall conform to Wis. Stats. § 86.26 and this chapter. Where a range of widths is provided, the actual width to be acquired shall be determined by the county planner:

Street Type	Minimum Right-of-Way (feet)	Minimum Radius of Curvature (feet)	Minimum/ Maximum Paved Widths (feet)	Maximum Grade (percent)
Collector	80	200	20/44	7
Local	66	100	20/44	10
Frontage	50	100	20/44	10
Cul-de-sac	66	100	20/44	10

 

(e)

Where an existing dedicated or platted half-street is adjacent to a tract being subdivided, the other half of the street shall be platted and dedicated by the subdivider. In all other instances, the creation of half streets in new subdivision plats is prohibited.

(f)

Street jogs with centerline offsets of less than 150 feet shall not be allowed on local streets. Offsets of less than 600 feet shall not be allowed on collector or arterial streets.

(g)

Streets shall be designed in accordance with basic principles of functional classification where each street is designed to encourage or discourage through traffic according to its classification as defined in section 48-1.

(h)

No more than two streets shall intersect at one point. Such intersections shall be laid out so that the angle of intersection is as nearly as possible at right angles, and in no instance shall streets intersect at less than a 75-degree angle.

(i)

Whenever a proposed subdivision contains or is adjacent to an arterial street or highway, adequate measures shall be taken by the subdivider to protect residential property and limit arterial and highway access by separating through and local traffic by the following means:

(1)

Reverse frontage with screen planting or fencing contained in a nonaccess reservation along the back property line.

(2)

A marginal access frontage road.

(3)

"No access" provisions.

(j)

Alleys in residential areas are prohibited.

(k)

Cul-de-sac streets designed to have the terminus permanently closed shall not exceed 1,000 feet in length, measured from the centerline of the last through street to the center of the bulb. Where topographical, environmental or other natural constraints warrant, the length may be extended at the discretion of the county planner. Culs-de-sac shall terminate in a circular turnaround centered on the roadway with a minimum right-of-way diameter of 120 feet and a minimum pavement diameter of 80 feet, and a minimum reverse curve radius of 50 feet.

(l)

Street names and numbering.

(1)

Street names for all proposed subdivisions shall comply with the provisions of section 46-93. Street names shall be subject to approval by the county planner.

(2)

Proposed streets which are a continuation of an existing street shall bear the name of the existing street. In all other instances, the proposed street name shall not duplicate existing street names. The use of the "Street," "Road," "Avenue," "Boulevard," "Drive," "Place," "Court" or similar description shall not be a distinction sufficient to constitute compliance with this subsection or chapter 46, article III.

(3)

Dwelling and business addresses for all proposed parcels in towns having adopted chapter 46, article III shall be assigned by the county planner.
