A.
Street arrangement.
(1)
Street layout shall conform to the arrangement, width and location
indicated on the Official Map, Comprehensive Plan, or development
plan where applicable. In areas for which such plan has 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 land
division or subdivision shall be designed so as to provide each lot
with satisfactory access to a public street.
(2)
Arterial streets shall be arranged so as to provide ready access
to centers of employment, centers of government 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.
(3)
Collector streets shall be arranged so as to provide ready collection
of traffic from residential areas and conveyance of this traffic to
the major street and highway system and shall be properly related
to the mass transportation system, to special traffic generators such
as schools, churches, shopping centers, and other concentrations of
population, and to the major streets into which they feed.
(4)
Local and 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.
Minor streets shall not exceed 800 feet in length measured from center
line to center line of intersecting streets.
[Amended by Ord. No. 1996-08-01]
(5)
Proposed streets 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 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. Temporary turnarounds may be required where the street
ends at the boundary of the subdivision.
(6)
Whenever the proposed subdivision contains or is adjacent to a major
street or highway, adequate protection of residential properties,
limitation of access and separation of through and local traffic shall
be provided by reversed frontage, with screen planting contained in
a nonaccess reservation along the rear property line, or by the use
of frontage streets.
(7)
Stream or lake shores shall have 60 feet of public access platted
to the low-water mark at intervals of not more than 1/2 mile as required
by § 236.16(3), Wis. Stats. The Village shall not be required
to improve any lands provided for public access pursuant to this subsection.
(8)
Reserve strips (usually owned parcels) controlling access to streets
or alleys are prohibited except where control of such strips is placed
with the Village under conditions approved by the Plan Commission.
(9)
Alleys shall be provided in commercial and industrial districts for
off-street loading and service access when required by the Plan Commission
but shall not be used in residential areas. When required, alleys
shall not be less than 24 feet wide and shall be continuous through
blocks. Dead-end alleys shall not be approved, and alleys shall not
connect to a major thoroughfare.
B.
Street names and building numbers.
(1)
Duplication of existing streets names in the Village and adjacent
towns by similar word, spelling, or sound shall not be permitted.
(2)
Where a street maintains the same general direction except for curvilinear
changes for short distances, the same name shall continue for the
entire length of the street. House numbering difficulties shall be
considered the determining factor in considering whether a change
of name is necessary due to curvilinear changes.
(3)
A street name shall be changed when required to conform to the proposed
or existing house number base.
(4)
A name which is assigned to a street which is not presently a through
street, due to intervening land over which the street extension is
planned, shall be continued for the separate portions of the planned
through street.
(5)
The following designations shall be used only in the situations indicated:
(a)
Boulevard: a street with a divided pavement, either existing
or planned. If the divided pavement ends but the street continues,
the same street name and suffix shall continue.
(b)
Lane: a street having a maximum length of 500 feet, serving
a maximum of 10 single-family dwellings.
(c)
Circle: a cul-de-sac of nine lots or more.
(d)
Court: a cul-de-sac of eight lots or fewer.
(e)
Parkway: a street abutting a park or greenway or creek.
(6)
The maximum number of street names at one intersection shall be three.
(7)
Street names shall be assigned so that no two intersections have
the same exact street names.
(8)
The name of any projection of a street shall remain unchanged even
if the projection terminates in a cul-de-sac.
(9)
The changing of a street name that does not duplicate an existing
street name shall only be approved where such change will eliminate
conflicts with other provisions of this section.
(10)
Service roads and highways served by them shall have the same
street name and designation.
(11)
Approval of street names on a preliminary plat will not reserve
the names nor shall the Village be required to accept such names at
the time of final platting.
(12)
A minimum number of letters is desirable in a street name. The
maximum number of letters, not including the prefix or suffix, shall
not exceed 12.
A.
Roadways. The subdivider shall be required to provide improved roadways
to meet the following minimum criteria for each street classification.
The Village of Belleville and Village Engineer may request additional
width or pavement structure based on the anticipated use of the roadway.
Requests for exceptions to these standard specifications shall only
be approved by the Public Works and Parks Committee.

Cul-de-sac streets.
(1)
Culs-de-sac shall not exceed 750 feet in length from the center line
of the intersecting street to the center of the cul-de-sac circle.
(2)
Culs-de-sac shall terminate in a circular turnaround having a right-of-way
diameter of 120 feet. The reverse curve on a cul-de-sac shall have
a fifty-foot minimum radius when the bulb is centered on the street
and a one-hundred-foot minimum radius when the bulb is offset.
C.

The grade of any street shall in no case be less than 0.50%.
(3)
All changes in street grades shall provide safe stopping sight distances
as conditions require.
(4)
Street grades shall be set at elevations which, to the greatest extent
possible, maintain the existing topography, therefore eliminating
the need for removal of natural ground cover for areas outside the
street right of way.
D.
Radii of curvature.
(1)
When a continuous street center line deflects at any one point by
more than 5°, a horizontal curve shall be introduced having a
radius of curvature on said center line of not less than the following:
(2)
A tangent at least 150 feet in length shall be provided between reverse
curves on arterial and collector streets and 100 feet in length between
reverse curves on local streets.
E.
Half streets. Where an existing dedicated or platted half street
is adjacent to the tract being subdivided, the other half of the street
shall be dedicated by the subdivider. Streets less than full width
on the boundary of the tract being subdivided shall not be less than
a width sufficient to produce a full pavement, a full terrace on the
plat side, and a reserve strip as determined by the Plan Commission.[2]
A.
Streets shall intersect each other at as nearly right angles as topography
and other limiting factors of good design permit.
B.
The number of streets converging at one intersection shall not be
more than two.
C.
The number of intersections along major streets and highways shall
be held to a minimum. Wherever practicable, the distance between such
intersections shall not be less than 1,000 feet from center line to
center line.
D.
Local streets shall not necessarily continue across arterial or collector
streets; but if the center lines of such minor streets approach the
major streets from opposite sides within 300 feet of each other, measured
along the center line of the arterial or collector street, then the
location shall be so adjusted that the adjoinment across the major
or collector street is continuous and a jog is avoided.
E.
Whenever practicable, the distance between local street intersections
shall be no less than 250 feet measured from center line to center
line.
A.
The widths, lengths, and shapes of blocks shall be suited to the
planned use of the land, zoning requirements, need for convenient
access, control and safety of street traffic, and the limitations
and opportunities of topography.
B.
Blocks in residential areas as measured in the long dimension from
street center line to street center line shall not be less than 600
feet nor more than 1,200 feet in length unless otherwise dictated
by exceptional topography or other limiting design factors.
C.
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 Plan Commission to provide adequate
pedestrian circulation or access to schools, shopping centers, churches,
or transportation facilities.
D.
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. 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.
E.
All utility lines for electric power and telephone service shall
be placed underground within easements along rear lot lines.
A.
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. The lots should be designed to provide an aesthetically
pleasing building site and a proper architectural setting for the
buildings contemplated.
B.
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 lake orientation.
C.
Lot sizes shall conform to the area and width requirements prescribed
for the zoning district in which the land is located.
D.
Every lot shall front or abut on a public street for a distance of
at least 50 feet, or in the case of culs-de-sac, 40 feet. The minimum
lot width measured at the building setback line shall be 75 feet.
(This applies in lieu of less stringent standard.)
E.
Side lot lines shall, as nearly as practicable, be at right angles
to straight streets or radial to curved street lines.
F.
Lots shall follow municipal boundary lines rather than cross them
whenever practicable.
G.
Corner lots shall have sufficient width to permit adequate building
setbacks from side streets.
H.
Residential lots fronting or backing on arterial streets shall be
platted with extra depth to permit generous distances between the
buildings and such trafficways.
I.
Depth and width of properties reserved or laid out for commercial
or industrial use shall be adequate to provide for the off-street
service and parking facilities required by the type of use and development
contemplated.
J.
Whenever a tract is subdivided into large parcels, such parcels shall
be arranged and dimensioned as to allow the future division of any
such parcel into normal lots in accordance with the provisions of
this chapter.
K.
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.
L.
Lots shall be graded to provide drainage as indicated on the master
site grading and drainage plan.
[Added by Ord. No. 2004-04-02]
Where not adequately controlled by zoning regulations, building
setback lines appropriate to the location and type of development
contemplated shall be recommended by the Plan Commission.
A.
Adequate easements shall be provided and dedicated on each side of
all rear lot lines, and on side lot lines where necessary, for the
installation of storm and sanitary sewers, gas and water mains, electric
lines, and telephone and cable television communication lines.
B.
Easements for electric, telephone, gas, and cable television communication lines shall be noted as "Utility Easements" on the final plat or certified survey map. Prior to approval of the final plat or certified survey map, the concurrence of the electric and communications companies serving the area as to the location and width of the utility easements shall be noted on the final plat or certified survey map (see § 600-19).
C.
All easements for storm and sanitary sewers, water mains, pedestrian
walks, and other public purposes shall be noted on the plat or certified
survey as "Public Easement for" followed by reference to the use or
uses for which they are intended.
D.
Where the electric or communications facilities or both are to be
installed underground, a plat restriction shall be recorded with the
final plat or certified survey map stating that the final grade established
by the subdivider on the utility easements shall not be altered by
more than six inches by the subdivider, his agent, or by subsequent
owners of the lots on which such utility easements are located, except
with written consent of the utility or utilities involved. The purpose
of this restriction shall be to notify initial and future lot owners
of the underground facilities at the time of purchase and to establish
responsibility in the event of damage to such facilities or the need
to alter such facilities.
E.
Where a land division, subdivision, or development plan is traversed
by a watercourse, drainageway, channel or stream, an adequate drainageway
or easement shall be provided as required by the Plan Commission.
The location, width, alignment, and improvement of such drainageway
or easement shall be subject to the approval of the Plan Commission
and parallel to streets or parkways and may be required in connection
therewith. Wherever possible, the stormwater drainage shall be maintained
by landscaped open channels of adequate size and grade to hydraulically
accommodate maximum potential volumes of flow; these sizes and design
details to be subject to review and approval by the Village Engineer
and Plan Commission. Where feasible, drainage easements should substantially
maintain existing water flow patterns onto neighboring lands.
[Added by Ord. No. 2004-04-02]
A.
Minor drainage system facilities must be designed to prevent stormwater
from encroaching on any traffic lane of a collector street, arterial
street, or the center 24 feet of any local street. Notwithstanding
the foregoing, water may inundate to the limits of any drainageway,
cul-de-sac, or permanently dead-end streets serving fewer than 10
dwelling units.
B.
Major drainage system facilities shall be capable of preventing stormwater
accumulation from inundating any buildings at the ground line, unless
such buildings are floodproofed or otherwise designed to prevent inconvenience
or damage from infrequent storm events. On arterial streets and in
commercially zoned districts, the major drainage system facilities
shall be designed to prevent the depth of water at the crown of the
street from exceeding six inches to permit the operation of emergency
vehicles.
C.
Multifamily residential, commercial and industrial developments shall
discharge stormwater to the drainage system at a rate of discharge
no greater than the pre-development ten-year storm event.
D.
Subdivisions and certified survey maps shall be graded to provide
drainageways between lots, blocks and adjacent properties. All grading
must ensure that all stormwater drainage discharges from the site
to the public right-of-way or dedicated drainageways, including storm
sewers. Drainageways shall be located, to the extent possible, along
property lines and may be encumbered by easements dedicated to the
public.
E.
All grades adjacent to the public right-of-way shall be graded consistent
with the grades established by the Village Engineer.
G.
All building floors and basement openings shall be a minimum of two
feet above the regional and/or local flood elevation or be floodproofed.
H.
The master site grading and drainage plan shall accommodate stormwater
drainage through the site as well as from the site.
