Editor's Note: This ordinance also repealed former Ch.
18, Subdivisions, adopted as Title 18 of the 1979 Code, as amended.
A.
The subdivider shall dedicate land for and improve streets as provided
herein.
B.
The proposed subdivision shall conform to:
1.
Any applicable official map ordinance. In areas for which an Official
Map has not been completed, the street layout shall recognize the
functional classification of various street types, and shall be developed
and located in proper relation to existing and proposed streets, with
due regard to topographical conditions, natural features, utilities,
land uses, and public convenience and safety as approved by the Village
Engineer. The subdivision and land division shall be designed so as
to provide each lot with satisfactory access to a public street, as
provided herein.
2.
Village of Grafton Municipal Code Chapter 11, Streets, Sidewalks,
and Public Places.
3.
The provisions of Chapter 236 of the Wisconsin Statutes, which are
adopted by reference.
4.
All applicable ordinances of the Village.
5.
Design and construction standards as established by the Village.
6.
The Comprehensive Plan of the Village.
7.
The rules of the State Department of Transportation, as may be promulgated
from time to time, whenever in the opinion of that Department the
proposed subdivision abuts existing or proposed state trunk highways
or connecting streets, and for the preservation of the public interest
and investment in such highway or street.
A.
The streets shall be designed and located in relation to existing
and planned streets, to reasonable circulation of traffic within the
subdivision and adjoining lands, to topographical conditions, to runoff
of stormwater, to public convenience and safety, in their appropriate
relations to the proposed uses of the area to be served.
B.
Major streets shall be properly integrated with the existing and
proposed system of major streets and highways and, insofar as practicable,
shall be continuous and in alignment with existing, planned or platted
streets with which they are to connect.
C.
Collector streets shall be properly related to the mass transportation
system, to special traffic generators such as schools, churches and
shopping centers, and to the major streets into which they feed.
D.
Minor streets shall be designed to reasonably conform to the topography,
to discourage use by through traffic, to permit efficient storm and
sanitary sewerage systems, and to require the minimum street area
necessary to provide safe and convenient access to abutting property.
Minor street locations and street grades shall be established wherever
practicable in such a manner to avoid excessive grading and to avoid
the excessive removal of tree growth and general leveling of the topography.
E.
Proposed streets shall be extended to the boundary lines of the tract
to be 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.
F.
Limited access highway and railroad right-of-way treatment. Whenever
the proposed subdivision or land division contains or is adjacent
to a limited access highway or railroad right-of-way, the design shall
provide the following treatment:
1.
When residential lots within the proposed subdivision back upon the
right-of-way of an existing or proposed limited access highway or
railroad, the following restriction shall be lettered on the face
of the plat: "Direct vehicular access to [name of road] from lots
abutting said road is prohibited."
2.
Commercial and industrial districts should provide, on each side
of the limited access highway or railroad, 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, unless provision has been made
for frontage roads.
3.
Streets parallel to a limited access highway or railroad right-of-way,
when intersecting a major street, highway or collector street which
crosses said railroad or highway, shall be located at a minimum distance
of 250 feet from said highway or railroad 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.
4.
Minor streets immediately adjacent and parallel to railroad rights-of-way
should be avoided.
G.
Protection of major streets and highways. Whenever a proposed subdivision
or land division contains or is adjacent to an major street or highway,
adequate protection of residential properties, limitation of access
and the separation of through and local traffic shall be provided
by:
H.
Wherever the proposed subdivision contains or is adjacent to a railroad
right-of-way or limited access highway, provisions shall be made on
each side of such right-of-way for streets approximately parallel
to and at a distance suitable for appropriate use of the land and
between such streets and the right-of-way, but not less than 150 feet.
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.
I.
Street widths.

of a minimum length equivalent in feet to 30 times the algebraic difference
in the rates of grade for streets, provided that no curve of less
than 50 feet in length need be used.
N.
Tangents. Tangents of at least 100 feet in length shall be introduced
between reverse curves on major and collector streets.
O.
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 names of the existing streets.
P.
Culs-de-sac. Cul-de-sac streets shall be not more than 700 feet in
length measured along their center lines from the streets of origin
to the ends of their right-of-way, unless specifically permitted by
Plan Commission approval. Each cul-de-sac shall have terminus of nearly
circular shape with the minimum right-of-way diameter being 120 feet
and the minimum outside curb diameter of 90 feet.

of lots of appropriate depth, except where otherwise required to separate
residential development from through traffic, or where lots abut a
lake or stream. 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 provisions of such use.
D.
Blocks intended for commercial, industrial and institutional use
must be designated as such, and the plan must show adequate off-street
areas to provide for parking, loading docks and such other facilities
as may be required to accommodate motor vehicles.

by the Plan Commission where deemed desirable to provide convenient
pedestrian circulation or access to schools, parks, playgrounds, shopping
centers, transportation and other community facilities.
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. In the subdividing of any land, due regard shall
be shown for all natural features such as tree growth, watercourses,
historic spots or similar conditions.
B.
Width and area of lots shall conform with lot width and area requirements
set forth in the Zoning Ordinance and in no case shall a lot in a
residential district have less than a minimum width of 50 feet at
the minimum building setback line and a minimum area of 7,000 square
feet.
C.
Depth of lots shall be in accordance with Plan Commission requirements,
but residential lots shall be not less than 100 feet in depth.
D.
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.
E.
Residential lots abutting on major streets and highways shall be
platted with sufficient depth to permit adequate separation between
the buildings and such trafficways.
F.
Lots abutting upon a watercourse, drainageway, channel or stream
shall be an additional depth or width as required to provide an acceptable
building site.
G.
Excessive depth in relation to width of lots shall be avoided. A
proportion of two to one shall normally be considered as a desirable
maximum for lot widths of 80 feet or more.
H.
Every lot shall front or abut on a dedicated public street right-of-way
for a minimum of 40 feet along cul-de-sac bulbs and 60 feet along
all other street segments. Lots with an access only to private drives
or streets shall be permitted only with Plan Commission approval.
I.
Side lot line shall be substantially at right angles or radial to
street lines.
J.
Where lots are created of a size larger than normal for the area,
the Plan Commission may require that the plat be so designed as to
allow for the possible future resubdivision of such lots into normal
sizes compatible with the area.
K.
Lots shall follow municipal boundary lines whenever practicable rather
than cross them.
L.
Every lot shall front or abut on a dedicated public street right-of-way
for a minimum of 40 feet along cul-de-sac bulbs and 60 feet along
all other street segments. Lots with an access only to private drives
or streets shall be permitted only with Plan Commission approval.
M.
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.
A.
Sidewalks shall be provided within a subdivision in accordance with
Title 11, Streets, Sidewalks and Public Places, of the Code of the
Village of Grafton and/or plans approved by the Village Plan Commission
along with the subdivision plat.
B.
Five-foot-wide concrete sidewalks shall normally be constructed on
one side of all frontage and both sides of all streets within developments.
C.
Sidewalks must be constructed along streets if they provide a link
between developments or link developments with support facilities
such as schools, shopping centers, employment centers, parks and other
public recreational facilities.
D.
The Plan Commission may exempt the following streets from sidewalk
construction: residential culs-de-sac, loop streets (eyebrows) or
dead-end streets serving eight or fewer residences and less than 400
feet in length; commercial or industrial streets that provide access
only to businesses within the immediate area. The Commission may allow
the construction of sidewalks on only one side of all other culs-de-sac
and dead-end streets.
E.
Sidewalk construction shall be in accordance with plans submitted
by the developer along with subdivision street plans and profiles.
In addition, wider than standard sidewalks may be required by the
Plan Commission in the vicinity of schools, commercial areas and other
places of public assemblage.
F.
Pedestrian trails. Pedestrian trails may be allowed or required in
lieu of or in addition to sidewalks within duplex, multifamily and
planned developments. Such trails shall be constructed of bituminous
asphalt materials and shall be at least five feet wide. Where such
trails are also to be used as bikeways, they shall be a minimum of
eight feet wide. Pedestrian trails shall be privately maintained.
Such trails may be allowed in lieu of sidewalks when, due to unique
subdivision design and/or terrain, they will provide a more convenient
link between the subdivision with schools, shopping centers, employment
centers and/or amenities.
A.
To minimize off-site water runoff from the subdivision and to ensure
positive drainage from all lots within each proposed block, the subdivider
shall submit, at time of preliminary plat, stormwater management and
grading plans for the subdivision as a whole and for each block within
the proposed subdivision. The Village may consider failure to submit
stormwater management and grading plans with preliminary plat submittal
a basis for denial of the preliminary plat.
B.
This plan shall be prepared so that storm water runoff from the subdivision as a whole is in compliance with provisions of Chapters 23.01 and 23.04 of the Village of Grafton Municipal Code. The Department of Public Works and their consultant will review the submitted stormwater management and grading plans for compliance with the provisions of these regulations and with the provision of Chapters 23.01 and 23.04, and said Department shall make a determination as to compliance or noncompliance with such provisions prior to action on the final plat by the Village Board.
C.
This grading plan shall include final grade elevations to be maintained
along rear lot lines. Design shall be based on environmentally sound
site planning and engineering techniques. The best available technology
shall be used to minimize off-site storm water runoff, increase on-site
infiltration, encourage natural filtration functions, simulate natural
drainage systems, and minimize off-site discharge of pollutants to
ground and surface water.
D.
Should the approved drainage plan require any grading or the installation
of storm water drainage facilities within any block or blocks, the
subdivider shall cause such grading or other improvements to be installed
at their expense at the same time the subdivision roads are being
graded. To ensure compliance with the approved grading plan, a covenant
shall be included on the face of the final plat referring to the grading
plan and requiring compliance therewith.

approved street tree plan.
D.
There shall be no less than one tree per platted lot.
E.
Alternative planting materials/types may be considered during review
of the plan by the Director of Public Works.
Before final approval of any plat, the subdivider shall install
monuments placed in accordance with the requirements of Chapter 236,
Wisconsin Statutes, and as may be required by the Director of Public
Works. The Director of Public Works may waive the placing of monuments
for a reasonable time on condition that the subdivider executes a
surety bond to ensure the placing of such monuments within the time
required.
A.
The subdivider shall construct sanitary sewers in such a manner as
to make adequate sanitary sewerage service available to each lot within
a subdivision or land division. Laterals extending from the sanitary
sewer main to the lot line to service each parcel of property within
the subdivision shall be installed.

H.
Prior to occupancy of any building, the building drainage system
shall be connected to the available storm sewer lateral. This connection
shall be the responsibility of the property owner. On lots that abut
navigable waterways, such as channels, rivers or lakes, this regulation
shall not apply if the sump water drainage system is designed to direct
sump water into said navigable waterway.
A.
The subdivider shall cause other utilities including but not limited
to gas, electrical power, and telecommunication facilities to be installed
in such a manner as to make adequate service available to each lot
in the subdivision.
B.

barrier.
C.
Associated equipment and facilities which are pertinent to underground
telephone and electric systems (such as, but not limited to, substations,
pad-mounted transformers, pad-mounted sectionalizing switches, pedestals,
mounted terminal boxes), may be located above ground. Such equipment
and facilities shall be located in rear or side yard areas.
A.
Easements shall be provided for any overhead or underground utility
service, including storm sewers or stormwater drainage and detention
where necessary.
C.
Public utility easements shall be a minimum of 12 feet wide, six
feet of same being on each of the adjacent lots or all 12 feet on
one lot where necessary, except where wider easements are required
by the Village Engineer.
D.
Easements shall be established at the rear of each lot and along
such other lot lines as to provide continuity or alignment from block
to block. At deflection points in these easements, if overhead utility
lines are contemplated, additional easements shall be established
for pole-line anchors.
E.
Drainage easements. Where a subdivision 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, the
drainage shall be maintained by an open channel with landscaped banks
and adequate width for maximum potential volume of flow.
F.
Lines to be underground in newly platted areas.
1.
All new utility lines installed within a newly platted area shall
be underground.
2.
Associated equipment and facilities which are appurtenant to underground
utilities, such as, but not limited to, substations, pad-mounted transformers,
pad-mounted sectionalizing switches and above grade pedestal-mounted
terminal boxes, may be located above ground. Such equipment and facilities
shall be located in rear yard areas.
3.
The subdivider or agent shall furnish proof to the Plan Commission
that such arrangements as may be required under applicable rates and
rules filed with the Public Service Commission of Wisconsin have been
made with the owner or owners of such lines or services for placing
their respective facilities underground as required by this section,
as a condition precedent to approval of the final plat or certified
survey map.
4.
Temporary overhead facilities may be installed to serve a construction
site or where necessary because of severe weather conditions. In the
latter case, within a reasonable time after weather conditions have
moderated or upon completion of installation of permanent underground
facilities, such temporary facilities shall be replaced by underground
facilities and the temporary facilities removed.
G.
Easement conditions.
1.
Adequate easements shall be provided and dedicated on each side of
all rear lot lines, and on side lot lines, across lots or along front
lot lines where necessary, for the installation of storm and sanitary
sewers, gas, water, electric and communications lines. Such easements
as required by the utility company or other private utility 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. All easements
for storm and sanitary sewers, water mains, pedestrian walks, and
other public purposes shall be noted thereon as "Public Easement for"
followed by reference to the use or uses for which they are intended.
2.
Where the utility facilities are to be installed underground, the
utility easements shall be graded to within six inches of final grade
by the subdivider, prior to the installation of such facilities, and
earth fill, piles or mounds of dirt shall not be stored on such easement
areas. Utility facilities when installed on utility easements whether
overhead or underground shall not disturb any monumentation in the
plat.
H.
Where the utility facilities 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 to the need to alter
such facilities. When the utility company uses a service application,
said application should also notify the initial and subsequent lot
owners of their responsibility regarding such underground facilities.
