The proposed land division shall conform to:
A. 
The provisions of Chapter 236 of the Wisconsin Statutes;
B. 
All applicable ordinances of the village;
C. 
The Official Map;
D. 
The rules of the Wisconsin Department of Transportation and Waukesha County relating to safety of access and the preservation of the public interest and investment in the streets if the subdivision or any lot contained therein abuts on a state trunk highway or connecting street.
A. 
General considerations. The streets shall be designed and located in relation to existing and planned streets, to topographical conditions and natural terrain features such as streams and existing tree growth, to public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets.
B. 
Conform to Official Map. The arrangement, width, grade and location of all streets shall conform to the Official Map of the village, if any exists.
C. 
Arrangement.
(1) 
Arterial streets shall be properly integrated with the existing and proposed system of major streets and highways.
(2) 
Collector streets shall be properly related to the mass transit system, to special traffic generating from facilities such as schools, churches and shopping areas, to population densities, and to the primary streets into which they feed.
(3) 
Secondary streets shall be laid out to conform as much as possible to topography, to discourage use by through traffic, to permit efficient drainage and sewer systems, and to require the minimum amount of street necessary to provide convenient, safe access to property.
(4) 
Railroad right-of-way or limited access highway. Where a land division borders on or contains a railroad right-of-way or limited access highway right-of-way, the Plan Commission may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land as for park purposes in residential districts or for commercial or industrial purposes in other districts.
(5) 
Access onto arterial and collector streets. Where a land division borders on or contains an existing or proposed arterial or collector street, the Plan Commission may require that marginal access streets be provided, that the backs of lots abut the primary or collector street and be provided with screen planting contained in a nonaccess reservation along the rear property line, and that other provisions be made for the adequate protection of residential properties and the separation of through and local traffic.
(6) 
Width. The right-of-way and roadway of all streets shall be of the width specified on the Official Map or Master Plan or, if no width is specified there, they shall be not less than the width specified below:
Road Type
Right-of-Way
(feet)
Roadway

Arterial street
80

Collector street
60
36
Secondary and marginal access streets

(7) 
Grades. The grade of major and collector streets shall not exceed 6%, unless necessitated by exceptional topography and approved by the Plan Commission. The grade of all other streets shall not exceed 10%. The minimum grade of all streets shall be 0.3%.
(8) 
Horizontal curves. A minimum sight distance with clear visibility, measured along the center line, shall be provided of at least 300 feet on major streets, 200 feet for collector streets and 100 feet on minor streets.
(9) 
Vertical curves. All changes in street grades shall be connected by vertical curves of a minimum length equivalent to 15 times the algebraic difference in the rate of grade for major streets and collector streets and 1/2 of this minimum length for all other streets.
(10) 
Tangents. A tangent at least 100 feet long shall be introduced between reverse curves on major and collector streets.
(11) 
Street names. New street names shall not duplicate the names of existing streets, but streets that are continuations of others already in existence and named shall bear the name of the existing streets.
(12) 
Cul-de-sac or dead-end streets. Streets designed to have one end permanently closed shall not exceed 500 feet in length and shall terminate with a turnaround of not less than 100 feet in diameter of right-of-way and a roadway turnaround of 80 feet in diameter.
(13) 
Reserve strips. Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the village under conditions approved by the Plan Commission.
(14) 
Half-streets. Where a half-street is adjacent to the subdivision, the other half of the street shall be dedicated by the subdivider.
(15) 
Intersections.
(a) 
Streets shall intersect as nearly as possible at right angles and not more than two streets shall intersect at one point unless approved by the Plan Commission.
(b) 
Property lines at street intersections shall be rounded with a radius of 15 feet or of a greater radius where the Plan Commission considers it necessary.
(c) 
Street jogs with center-line offsets of less than 125 feet shall be avoided. Where streets intersect major streets, their alignment shall be continuous.
A. 
Easements across lots or centered on rear or side lot lines shall be provided for utilities where required by the Plan Commission and shall be at least 10 feet wide.
B. 
Where a land division is traversed by a watercourse, drainageway, channel, or stream, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the lines of such watercourse, and such further width or construction, or both, as will be adequate for the purpose. Wherever possible, it is desirable that the drainage be maintained by an open channel with landscaped banks and adequate width for maximum potential volume of flow.
A. 
General. The size, shape and orientation of lots shall be appropriate for the location of the land division and for the type of development and use contemplated.
B. 
Lot dimensions. Lot dimensions shall conform to the requirements of the underlying zoning district.
C. 
Depth and width of properties reserved or laid out for commercial and industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated.
D. 
Residential lots, fronting on major streets and highways, should be platted with extra depth to permit generous distances between the structures and such traffic ways.
E. 
Access to public street. Every lot shall front or abut on a public street. Lots with an access only to private drives or streets shall be permitted only with Plan Commission approval.
F. 
Lots at right angles. Lots at right angles to each other should be avoided wherever possible, especially in residential areas.
G. 
Lot lines. Side lot lines shall be substantially at right angles or radial to street lines.
H. 
Large lots. In case a tract is subdivided into parcels containing two or more acres, such parcels shall be arranged to allow the resubdivision of any parcels into normal lots in accordance with the provisions of this chapter.
I. 
Municipal boundaries. Lots shall follow municipal boundary lines whenever practicable, rather than cross them.
J. 
Double frontage. Double frontage and reversed frontage lots shall be avoided except where necessary to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation.
