Whenever the proposed subdivision contains or is adjacent to
a limited-access highway right-of-way, the design shall provide the
following treatment:
A. Landscape bufferyard easement required. When lots within the proposed subdivision, certified survey map, or condominium back upon the right-of-way of an existing or proposed limited access arterial street or highway, a planting strip (landscape bufferyard easement) a minimum of 30 feet in depth (width), or as otherwise required by Chapter
490, Zoning and Shoreland/Floodplain Zoning, of this Code, shall be provided adjacent to the highway or railroad in addition to the normal lot depth. This strip shall be a part of the platted lots but shall have the following restriction lettered on the face of the plat: "Landscape Bufferyard Easement: This strip is reserved for the planting of trees and shrubs; the building of structures hereon is prohibited."
B. Streets serving commercial and industrial properties. Commercial
and industrial properties shall have provided, on each side of the
limited-access highway, streets approximately parallel to and at a
suitable distance from such highway or railroad for the appropriate
use of the land between such streets and highway or railroad, but
not less than 150 feet.
C. Streets parallel to a limited-access highway right-of-way. Streets
parallel to a limited-access highway right-of-way, when intersecting
a major street and highway or collector street which crosses said
highway, shall be located at a minimum distance of 250 feet from said
highway right-of-way. Such distance, where desirable and practicable,
shall be determined with due consideration of the minimum distance
required for the future separation of grades by means of appropriate
approach gradients.
D. Minor streets adjacent and parallel to arterial streets and highways.
Minor streets immediately adjacent and parallel to arterial streets
and highways shall be avoided in residential areas.
The minimum right-of-way and roadway width of all proposed streets
and alleys shall be as specified by the county development or Village
Comprehensive Plan, plan component, Official Map, neighborhood development
study, or jurisdictional highway system plan of the county or local
municipality, or, if no width is specified therein, the minimum widths
shall be as shown in Table 1. Street sections are for standard arterial
streets only. Cross sections for freeways, expressways, and parkways
should be based upon detailed engineering studies. All public roadways
shall have an urban section unless otherwise authorized by the Village
Board. In addition roadway sections shall conform to the Standard
Development Details and as follows:

NOTES:
|
(a) See Article XV for definitions of "urban area" and "rural area."
|
(b) An easement may be permitted
by the Plan Commission rather than a dedicated public right-of-way.
|
(c) "Curb lawn" is defined as that
area located between curb/gutter and sidewalk.
|
A. Cul-de-sac streets.
(1) Length. Cul-de-sac streets designed to have one end permanently closed
shall not exceed 750 feet in length.
(2) Adequate turnaround to be provided. Cul-de-sac streets shall terminate
in a circular turnaround having a minimum right-of-way radius of 60
feet and a minimum outside curb radius of 45 feet.
B. Temporary street termination. Temporary termination of streets intended
to be extended at a later date shall be accomplished with a temporary
cul-de-sac in accordance with the standards set forth above or by
the construction of a temporary "T" intersection 33 feet in width
and 33 feet in length abutting the right-of-way lines of the access
street on each side.
C. Roadway elevations. Elevations of roadways passing through floodplain
areas shall be designed in the following manner:
(1) Freeways and arterial streets and highways shall be designed so they
will not be overtopped by the 100-year recurrence interval flood.
(2) Collector streets shall be designed so they will not be overtopped
by the fifty-year recurrence interval flood.
(3) Local streets shall be designed so they will not be overtopped by
the twenty-five-year recurrence interval flood.
D. New and replacement bridges and culverts.
(1) All new and replacement bridges shall be constructed in accordance
with all applicable state statutes and codes and shall be submitted
to the Department of Natural Resources to ensure compliance therewith.
(2) All new and replacement bridges and culverts over perennial waterways,
including pedestrian and other minor bridges, in addition to meeting
other applicable requirements, shall be designed so as to accommodate
the 100-year recurrence interval flood event without raising the peak
stage, either upstream or downstream, more than 0.01 foot above the
peak stage for the 100-year recurrence interval flood.
(a)
Larger permissible flood stage increases may be acceptable for
reaches having topographic land use conditions which could accommodate
the increased stage without creating additional flood damage potential
upstream or downstream of the proposed structure.
(b)
Such bridges and culverts shall be so designed and constructed
as to facilitate the passage of ice flows and other debris.
E. Street grades.
(1) Street grades shall be established wherever practicable so as to
avoid excessive grading, the promiscuous removal of ground cover and
tree growth, and general leveling of the topography.
(2) All changes in street grades shall be connected by vertical curves
of a minimum length equivalent in feet to 14 times the algebraic difference
in the rates of grade for arterial streets and 1/2 this minimum for
all other streets.
(3) Unless necessitated by exceptional topography subject to the approval
of the Plan Commission, the maximum center-line grade of any street
or public way shall not exceed the following:
(a)
Arterial and collector streets: 6%.
(b)
Minor streets, alleys, and frontage streets: 8%.
(c)
Pedestrianways: 8% and meeting all applicable Americans with
Disabilities Act (ADA) Accessibility Guidelines.
(4) The grade of any street shall in no case exceed 12% or be less than
0.60% for urban sections and 1.0% for rural sections.
(5) Street grades may be varied as provided for in this subsection, but
in no case shall any street grade be permitted to exceed 12%.
F. Radii of curvature.
(1) When a continuous street center line deflects at any one point by
more than 10, a circular curve shall be introduced having a radius
curvature on said center line of not less than the following:
(a)
Arterial streets and highways: 500 feet.
(b)
Collector streets: 300 feet.
(d)
Rural and suburban streets: may be less than 100 feet in environmentally
sensitive areas as determined by the Plan Commission.
(e)
A tangent at least 100 feet in length shall be provided between
reverse curves on arterial and collector streets.
G. Half streets. Where an existing dedicated or platted half street
is adjacent to the tract being subdivided by either a subdivision
plat or certified survey map, the other half of the street shall be
dedicated by the subdivider. The platting of new half streets shall
not be permitted.
Streets shall intersect each other at as nearly right angles
as topography and other limiting factors of good design permit. In
addition:
A. Maximum number of streets converging at single intersection. The
number of streets converging at one intersection shall be reduced
to a minimum, preferably not more than two.
B. Number and distance between intersections along arterial streets
and highways. The number of intersections along arterial streets and
highways shall be held to a minimum. Wherever practicable, the distance
between such intersections shall not be less than 1,200 feet.
C. Rounding of property lines at street intersections required. Property
lines at street intersections may be rounded with a minimum radius
of 15 feet, or of a greater radius when required by the Plan Commission,
or shall be cut off by a straight line through the points of tangency
of an arc having a radius of 15 feet.
D. Continuous alignment of minor streets required at intersections.
Minor 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 250 feet of each other, measured
along the center line of the arterial or collector street, then the
location shall be adjusted so that the adjoinment across the major
or collector street is continuous. Thus, a jog is avoided.
The widths, lengths, and shapes of blocks that are created shall
be suited to the planned use of the land, zoning requirements, overall
residential density, the need for convenient access, control and safety
of street traffic, and the limitations and opportunities of topography.
In addition:
A. Maximum block length. The length of blocks in residential areas shall not, as a general rule, be less than 600 feet nor more than 1,500 feet in length unless otherwise dictated by Chapter
490, Zoning and Shoreland/Floodplain Zoning, of this Code, exceptional topography, environmental features, request of the Plan Commission, or other limiting factors of good design.
B. Pedestrianways required at center of blocks over 900 feet in length.
Pedestrianways (easement or dedicated public right-of-way) of not
less than 20 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, parks, shopping centers, churches, or transportation
facilities.
C. Block width. The width of blocks shall be wide enough 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.
D. Mid-block utility easements required. Utility easements for electric
power and telephone service shall, where practical, be placed on mid-block
easements along rear lot lines.
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
building contemplated. In addition:
A. Lot lines. Lot lines shall follow municipal boundary lines rather
than cross them.
B. Double frontage lots. 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. Access. Every lot shall front or abut, for a distance of at least
40 feet, on a public street or private road easement.
D. Area and dimensional requirements of lots. Areas and dimensions of all lots shall conform to the requirements of Chapter
490, Zoning and Shoreland/Floodplain Zoning, of this Code for areas of the unincorporated Village of Salem Lakes. Those building sites not served by a public sanitary sewage system or other approved system shall be sufficient to permit the use of an on-site soil absorption sewage disposal system designed in accordance with Ch. SPS 383, Wis. Adm. Code.
E. Lot depth. Excessive depth of lots in relation to width shall be
avoided. 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.
F. Lot width. Width of lots shall conform to the requirements of Chapter
490, Zoning and Shoreland/Floodplain Zoning, of this Code or other applicable ordinance.
G. Corner lots. Corner lots shall have an extra width of 10 feet to
permit adequate building setbacks from side streets.
H. Plats abutting a lake or stream. In any plat abutting a lake or stream,
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.
I. Land remnants. All remnants of lots below minimum size left over
after subdividing of a larger tract must be added to adjacent lots,
or a plan shown as to future use, rather than allowed to remain as
unusable parcels.
J. Large lots. Where lots are created of a size larger than the minimum
lot size required by the underlying zoning district, the Plan Commission
may require that the plat be so designed as to allow for the possible
future resubdivision of such lots into lot sizes compatible with the
underlying zoning district.
This section sets forth vehicular access requirements for certified
survey maps, subdivision plats, and condominiums which abut arterial,
collector, and minor streets. This chapter recognizes that public
streets are a public investment which require control mechanisms in
order to assure both public safety and functional capacity. Proposed
certified survey maps, subdivision plats, and condominiums for residential
and nonresidential uses shall meet the following requirements:
A. Access standards for all residential and nonresidential uses. All
proposed certified survey maps, subdivision plats, and condominiums
proposed for residential and/or nonresidential uses located in residential
and/or nonresidential zoning districts shall meet the following standards:
(1) Controlled access to public streets. Lot and parcel vehicular access
points shall be permitted only at locations in accordance with this
chapter and other Village of Salem Lakes adopted plans, ordinances,
or plans approved by the Plan Commission. The Plan Commission may
limit vehicular access to any adjoining arterial, collector, or minor
street.
(2) Distance between vehicular access points. The spacing of vehicular
access points from arterial, collector, and minor streets to lots
and parcels shall be determined as a function of arterial street and
highway, collector street, and minor street operating speeds. The
minimum spacing between vehicular access points along such streets
or highway shall be determined according to Table 2, unless otherwise
authorized by the Village Board. These spacings are based upon average
vehicle acceleration and deceleration rates and are considered necessary
to maintain safe traffic operation.

(3) Limitation of access to interstate, United States, and state trunk
highways. No new direct vehicular access shall be allowed to interstate,
United States, and state trunk highway public rights-of-way unless
approved by the Wisconsin Department of Transportation, Kenosha County,
and the Plan Commission.
(4) Temporary access.
(a)
On Village streets, the Village Board may grant temporary access
to properties and require their closure when access through adjoining
properties is acquired upon recommendation by the Plan Commission.
Such access shall be temporary, revocable, and subject to any conditions
required and shall be issued for a period not to exceed 12 months.
(b)
Temporary access to state highway rights-of-way is reviewed
and may be approved by the Wisconsin Department of Transportation.
It is the subdivider's responsibility to obtain all necessary
approvals from the Wisconsin Department of Transportation for all
such temporary access points proposed prior to certified survey map,
subdivision plat, or condominium approval by the Village.
(5) Area circulation plan. The Plan Commission may require the preparation
of an area circulation plan for the proposed certified survey map,
subdivision plat, or condominium or covering several properties in
an area surrounding a proposed certified survey map, subdivision plat,
or condominium. The delineation of the area for the preparation of
an area circulation plan shall be determined by the Plan Commission.
Such a plan may require the sharing of access locations or temporary
access. All landowners, except those with a previously approved certified
survey map, subdivision plat, or condominium, shall be required to
conform to such an area circulation plan once it is adopted by the
Plan Commission as a component, or element, of the Village Comprehensive
Plan. The Plan Commission may require that such an area circulation
plan be prepared based upon the conduct of a traffic impact analysis
conducted by a licensed professional engineer with expertise in traffic
engineering. The Village Engineer shall review all such studies and
assist the Plan Commission.
(6) Vehicular nonaccess reservations required. The Plan Commission may
require that deed restrictions be placed on certified survey maps,
subdivision plats, or condominiums in order to limit vehicular access
to abutting arterial, collector, or minor streets and highways. A
landscaped bufferyard of adequate opacity, determined by the Plan
Commission or other Village ordinances, shall be provided in vehicular
nonaccess reservations along the property line abutting a public street
right-of-way. In such situations, vehicular access to such lots may
be provided by an abutting minor or collector street at designated
access driveways. Such vehicular nonaccess reservations shall be graphically
so noted on certified survey maps, subdivision plats, or condominium
plats prior to their approval by the Village.
(7) Arterial street and highway access and street intersections. No new
direct public or private access shall be permitted to an arterial
street or highway within 115 feet of the intersection of the right-of-way
lines of another arterial street or highway, and, where lot or parcel
size permits, no new direct public or private access shall be permitted
to an arterial street or highway within 500 feet of the intersection
of the right-of-way lines of another arterial street.
(8) Minor streets and vehicular access point alignments. Minor streets
and vehicular access points along both sides of a collector and/or
arterial street shall be aligned to assist in reducing the number
of driveways needed and to improve safety conditions related to access
to the street system.
(9) Sight distance and driveway placement. Direct vehicular access placement
on abutting collector and arterial streets and highways shall be such
that an exiting vehicle has a minimum unobstructed sight distance
according to Table 3 based upon the operating design speed of the
abutting collector or arterial street or highway, unless otherwise
authorized by the Village Board.

B. Access standards for nonresidential and multiple-family residential
uses. All proposed certified survey maps, subdivision plats, and condominiums
proposed for nonresidential and multiple-family residential uses located
in nonresidential and/or multiple-family residential zoning districts
shall meet the following standards:
(1) Maximum number of vehicular access points per lot. Generally, along
arterial streets and highways (including lots which abut the frontage
roads of said rights-of-way), where the abutting street frontage is
less than 350 feet, a maximum of one vehicular access point shall
be permitted to a particular lot from each of any one or two abutting
arterial streets and highways. One additional driveway entrance along
a single continuous lot with frontage in excess of 400 feet may be
permitted by the Plan Commission. When a shared vehicular access point
is used by two or more abutting lots, said shared vehicular access
point shall be considered as one single vehicular access point for
each lot or parcel served.
(2) Provision of shared vehicular access points between lots. Vehicular
access points planned to be located along property lines or within
five feet of a property line shall be shared vehicular access points
with the abutting lot or parcel. The vehicular access point center
line may be the property line between two lots or parcels of land
or may be a mutually agreed upon land access easement.
Building setback lines appropriate to the location and type
of development contemplated, which are more restrictive than the regulation
of the zoning district in which the subdivision, certified survey
map, or condominium is located, may be required by the Plan Commission.
