A.Â
Arterial streets. Arterial streets shall be arranged so as to provide
ready access to centers of employment, centers of governmental activity,
community shopping areas, community recreation and points beyond the
boundaries of the community. They shall also be properly integrated
with and related to the existing and proposed system of major streets
and highways and shall be, insofar as practicable, continuous and
in alignment with existing or planned streets with which they are
to connect. They shall provide for efficient, safe and direct connection
to, or separation of, neighborhoods and for circulation to destinations
outside the residential area.
B.Â
Collector streets. Collector streets shall be arranged so as to provide
ready collection of traffic from residential areas and conveyance
of this traffic to the arterial street and highway system and shall
be properly related to the mass transportation system, to special
traffic generators such as schools, churches and shopping centers
and other concentrations of population and to the arterial streets
into which they feed. They provide for circulation to serve local
traffic moving between minor streets and arterial streets.
C.Â
Minor streets. Minor streets shall be arranged to conform to the
topography, to discourage use by through traffic, to permit the design
of efficient storm and sanitary sewerage systems and to require the
minimum street area necessary to provide safe and convenient access
to abutting property.
A.Â
In any new subdivision, the street layout shall conform to the arrangement,
width and location indicated on the Official Map, Comprehensive Plan
or component neighborhood development plan of the Town. In areas for
which such plans have not been completed, the street layout shall
recognize the functional classification of the various types of streets
and shall be developed and located in proper relation to existing
and proposed streets, to the topography, to such natural features
as streams and tree growth, to public convenience and safety, to the
proposed use of the land to be served by such streets, and to the
most advantageous development of adjoining areas. The subdivision
shall be designed so as to provide each lot with satisfactory access
to a public street.
B.Â
All proposed streets in the new development shall extend to the boundary
lines of the tract being subdivided unless prevented by topography
or other physical conditions or unless, in the opinion of the Town
Plan Commission, such extension is not necessary or desirable for
the coordination of the layout of the subdivision or for the advantageous
development of the adjacent tracts.
C.Â
Reserve strips or "spite strips" shall not be allowed on any plat
to control access to streets or alleys from abutting property except
where control of such strips is placed with the Town under conditions
approved by the Town Plan Commission.
D.Â
Alleys shall be provided in commercial and industrial districts for
off-street loading and service access unless otherwise required by
the Town Plan Commission, but shall not be approved in residential
districts. Dead-end or crooked alleys shall not be approved, and alleys
shall not connect to an arterial street.
F.Â
Half streets are streets which are only a portion of the required
width and are usually platted along property lines. These half streets
shall be prohibited except where it is deemed essential for the reasonable
development of the subdivision in conformity with the other requirements
of these regulations; and where the Commission finds it will be practical
to require the dedication of the other half when the adjoining property
is subdivided, the other half of the street shall be platted within
such tract.
G.Â
Street names shall be required for all proposed public streets and
shall not duplicate or be confused with the name of an existing street
within the Town. Streets that are extensions, or that are proposed
to be aligned with existing named streets, must bear the names of
these streets. Street signs shall be required at all intersections
and shall be installed by the subdivider. Their location and design
shall be determined and approved by the Town.[1]
The right-of-way of all streets shall be as set forth in the
Town road specifications resolution.
A.Â
Where a subdivision or minor land division abuts or contains an existing
or proposed major highway or classified as an arterial or collector
highway and which may be shown on the Waukesha County Established
Street and Highway Width Map, the Town may require a frontage road
or a nonaccess reservation along the property contiguous to such highway,
or other treatment as may be necessary for adequate protection of
residential properties and to separate minor and arterial traffic
and prohibit direct private vehicular access to such arterial or collector
highway.
B.Â
Where the proposed subdivision or minor land division abuts any other
Town road, mill tax road or other street which the Town deems necessary
to preserve as a public or future public right-of-way, additional
land shall be dedicated to bring the width of the right-of-way up
to Town road standards.
A.Â
Unless necessitated by exceptional topography subject to the approval
of the Plan Commission, the maximum center-line grade of any public
way shall not exceed the following, and the grade of any street shall
in no case exceed 10% or be less than 1/2 this minimum for all other
streets:
B.Â
Street grades shall be established wherever practicable so as to
avoid excessive grading, the promiscuous removal of ground cover and
tree growth, and the general leveling of the terrain. Tree removal
within the right-of-way shall be as required by the Town Board and
may be required by the County Highway Commission along county trunk
highways where it is necessary to obtain proper vision or additional
pavement width. All changes in street grades shall be connected by
vertical curves of a minimum length equivalent in feet to 15 times
the algebraic difference in the rates of grade for arterial streets
and 1/2 this minimum for all other streets.
C.Â
When a continuous street center line deflects at any one point by
more than 5°, a circular curve shall be introduced having a radius
of curvature on such center line of not less than the following:
D.Â
A tangent at least 100 feet in length shall be provided between reverse
curves on arterial and collector streets.
A.Â
Streets shall intersect at right angles, and not more than two streets
shall intersect at one point.
B.Â
Intersections must be approached on all sides by grades not to exceed
4% for a distance of at least 50 feet in length unless exceptional
topography would prohibit these grades.
C.Â
The minimum turning radius at an intersection shall not be less than
40 feet.
D.Â
Vision triangles providing unobstructed views in both directions
perpendicular to the line of sight shall be maintained at all intersections
in accordance with the Town Zoning Code. Where intersections occur
at county trunk highways, the following standards shall apply:

E.Â
No building obstruction to view is permitted in this triangular area,
and appropriate statements regarding those restrictions shall be provided
on the plat or survey document.
F.Â
If a proposed street is to enter a Town, county or state arterial
and it is deemed a hazardous entrance by the governing body having
jurisdiction over the road, it will be the responsibility of the subdivider
to correct the potential hazard through an agreement with the governing
body or else relocate the proposed entrance to a more suitable location.
G.Â
The following distances between intersections must be observed:
(1)Â
Minor and collector streets may not empty into state and federal
highways at intervals less than 1,300 feet and into arterials at intervals
less than 1,000 feet. They shall be in alignment with existing and
planned streets entering the above highways from the opposite side.
(2)Â
If the intersections on minor and collector streets are not in alignment,
the distance between streets opening up on opposite sides of any existing
or proposed streets must be at least 150 feet measured along the intersecting
center line. Where the streets enter on the same side, the intersection
distance measured from the center line shall be at least 300 feet.
The width, length, and shapes of blocks shall be suited to the
planned use of the land; zoning requirements; the need for convenient
access, control and safety of street traffic; and the limitations
and opportunities of topography.
A.Â
The lengths, widths and shapes of blocks shall be determined by provisions
for building sites suitable to meet the needs of the type of use contemplated;
zoning ordinance requirements pertaining to lot size and dimensions;
needs for convenient access; circulation, control and safety of street
traffic; limitation and opportunities of topography. Block lengths
shall normally not exceed 2,000 feet or be less than 600 feet in length.
B.Â
Pedestrianways of not less than 10 feet in width may be required
near the center and entirely across any block over 900 feet in length
where deemed essential by the Town Plan Commission to provide adequate
pedestrian circulation or access to schools, parks, shopping centers,
churches or transportation facilities.
C.Â
Blocks shall have sufficient width to provide for two tiers of lots
of appropriate depth except where otherwise required to separate residential
development from through traffic. The width of lots or parcels reserved
or laid out for commercial or industrial use shall be adequate to
provide for off-street service and parking required by the use contemplated
and the area zoning restrictions for such use.
The size, shape and orientation of lots shall be appropriate
for the location of the subdivision and for the type of development
and use contemplated and shall conform in all respects to the lot
size and width requirements set forth in the Town Zoning Code. The
lots should be designed to provide an aesthetically pleasing building
site and a proper architectural setting for the buildings contemplated.
A.Â
Side lot lines shall be at right angles to straight street lines
or radial to curved street lines on which the lots face. Lot lines
shall follow municipal boundary lines rather than cross them.
B.Â
Double-frontage and reverse-frontage lots shall be prohibited except
where necessary to provide separation of residential development from
through traffic or to overcome specific disadvantages of topography
and orientation.
C.Â
Lots shall normally have a minimum average depth of 150 feet. Excessive
depth in relation to width shall be avoided if possible, and a proportion
of 2:1 is considered to be a desirable ratio under normal conditions.
The depth of lots or parcels reserved or laid out for commercial or
industrial use shall be adequate to provide for off-street service
and parking required by the use contemplated and the area zoning restrictions
for such use.
D.Â
Corner lots shall be 20% wider than the minimum width as required
for lots less than 150 feet in width. Where the required minimum average
width of lots is 150 feet or greater, corner lots shall not be required
to be increased in width.
E.Â
Lands lying between the meander line and the water's edge and any
otherwise unplattable lands which lie between a proposed subdivision
and the water's edge shall be included as part of lots, outlots or
public dedications in any plat abutting a lake or stream. All lands
under option to the subdivider or to which he holds any interest that
abut the proposed subdivision and a lake or stream shall also be included.
F.Â
All lots must abut a public street for at least 60 feet, except that
dimension may be reduced on culs-de-sac or sharp curves where the
lot lines radiate from the street. However, under special conditions
a private road may be utilized in accordance with the applicable provisions
of the Zoning Code.
G.Â
Lots abutting navigable water shall be designed for use by one family
only.
In the design of the plat, due consideration shall be given to the reservation of suitable sites of adequate area for future school, parks, playgrounds, drainageways and other public purposes. If designated on the Comprehensive Plan, Comprehensive Plan component, Official Map or component neighborhood development plan, such areas shall be made a part of the plat as stipulated in § 265-10 of these regulations. If not so designated, consideration shall be given in the location of such sites to the preservation of scenic and historic sites, stands of fine trees, marshes, lakes and ponds, streams, shorelands and ravines and other natural features.
A.Â
Pedestrian easements or dedications, not less than 10 feet in width,
shall be required where deemed necessary to provide access to playgrounds,
parks, schools, shopping centers or other community facilities.
B.Â
Utility easements shall be provided as may be deemed necessary to
those utility companies having installations in the plat. The utility
companies shall review all plats to determine whether easements will
be necessary and where they should be required.
C.Â
Where a subdivision is traversed by a drainageway or stream, an adequate
easement shall be provided as deemed necessary by the Town Engineer.
The location, width, alignment and improvement of such drainageway
or easement shall be subject to approval by the Town Engineer or the
county; and parallel streets or parkways may be required in connection
therewith. Where necessary, stormwater drainage shall be maintained
by landscaped, open channels of adequate size and grade to hydraulically
accommodate maximum potential volumes of flow, subject to review and
approval by the Town Engineer. Where deemed necessary, the Town or
county may require these channels to be enclosed with pipe.
