All required improvements shall be constructed in accordance with plans and standard specifications approved by the City Public Works and Safety Committee, City Engineer, Wisconsin Department of Natural Resources and Milwaukee Metropolitan Sewerage District, as may be appropriate. Such plans and standard specifications shall be submitted, reviewed and approved in accordance with § 392-49 of this chapter.
A.
The improving of a dedicated roadway to City specifications must
follow the following guidelines: All land divisions which create new
public right-of-way shall be required to improve, within said right-of-way,
a public road to City of Muskego specifications and detail drawings.
Should the road end with a permanent cul-de-sac, land must be dedicated
per City standards and the road constructed to City of Muskego specifications.
Should the road end with a future possible road extension, a temporary
cul-de-sac may be constructed with a temporary easement; however,
the size must be the same as a permanent cul-de-sac. City of Muskego
stormwater management requirements must be met should the improvements
add more than 1/2 of an acre of impervious surface. All roadway, grading,
storm sewer, and stormwater plans must be reviewed by the City of
Muskego as required by Municipal Code. The following requirements
vary by the size of the parcels being divided:
(1)
Should a land division create parcels with an average size of less
than or equal to 40,000 square feet, the road shall be built to City
specifications that include curb and gutter and storm sewer.
(2)
Should a land division create parcels with an average size of greater
than 40,000 square feet, the developer may choose to request a Public
Works and Safety Committee decision regarding the type of improvements
required. The only option the Public Works and Safety Committee will
consider other than curb and gutter section is ditch section construction
per City of Muskego specifications. Should this option be permitted,
the ditch sections shall be maintained by the developer initially
and ultimately the homeowners' association. Furthermore, these restrictions
outlining the responsibility for this maintenance shall be recorded
in a developer's agreement approved the City's Common Council concurrent
with the final land division document.
(3)
Private driveways within newly created public right-of-way are not
allowed under any circumstance.
B.
Improvements to be extended to farthest limit of parcel or lot. Any
and all improvements, streets, or utility services required by this
chapter, for the subdivision, certified survey map, or condominium
plat, shall be extended to the farthest limit of the parcel or lot
as set forth on the plans and specifications approved by the City.
If determined by the Plan Commission, based on the information of
engineering staff, that a resulting development will cause increased
effects on existing infrastructure, the cost of all reasonably necessary
improvements on the exterior of a development, such as expanded roadways,
intersections, and/or utility extensions, shall be paid by the developer/owner.
C.
Improvements to be extended to farthest affected area. Any and all
improvements, streets, or utility services required by this chapter,
for the subdivision, certified survey map, or condominium plat, shall
be extended to the farthest affected area. If determined by the Public
Works and Safety Committee or Plan Commission, based on the information
of engineering staff, that a resulting development will cause increased
effects on infrastructure, the cost of all improvements on the exterior
of a development, such as expanded roadways, intersections, and/or
utility extensions, shall be paid by the developer/owner.
The subdivider shall install survey monuments placed in accordance
with the requirements of § 236.15, Wis. Stats., and as may
be required by the City Engineer.
A.
Cut and filled lands shall be graded in accordance with the approved
plans or the soil's angle of repose, whichever is the lesser, and
an approved cover shall be established within 30 days following completion
of grading operations or such additional time period as may be approved
by the City Engineer.
B.
The subdivider shall grade the full width of the right-of-way of
all streets proposed to be dedicated in accordance with plans and
standard specifications approved by the City Public Works and Safety
Committee and any agency having jurisdiction, including the Wisconsin
Department of Natural Resources, upon the recommendation of the City
Engineer. The subdivider shall grade the roadbeds in the street rights-of-way
to subgrade.
C.
Where electric and communication 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 or construction materials
shall not be stored on such easement areas.
After the installation of all utility and stormwater drainage
improvements, the subdivider shall surface all roadways, in streets
proposed to be dedicated, to the widths prescribed by these regulations
and the adopted comprehensive plans or adopted plan components. Such
surfacing shall be done in accordance with plans and standard specifications
approved by the City Public Works and Safety Committee, upon the recommendation
of the City Engineer, and adopted by the Common Council or its authorized
agents. The second lift of asphalt shall be installed in accordance
with policies established from time to time by the Public Works and
Safety Committee.
The Common Council may require the subdivider to construct concrete
curb and gutters in accordance with plans and standard specifications
approved by the City Public Works and Safety Committee, upon the recommendation
of the City Engineer, and adopted by the Common Council or its authorized
agents. Mountable curbs shall generally be constructed. Wherever possible,
provision shall be made at the time of construction for driveway access
curb cuts. The cost of installation of all inside curbs and gutters
for dual roadway pavements on the established arterial street and
highway system for the City shall be determined based upon policies
established from time to time by the Public Works and Safety Committee.
A.
The Plan Commission and Common Council may require the subdivider
to construct a concrete sidewalk or asphalt off-road path on one side
of all frontage streets and on one or both sides of all other streets
within the subdivision. The construction of all sidewalks or off-road
paths shall be in accordance with plans and standard specifications
adopted by the Common Council.
B.
Wider than standard sidewalks or off-road paths may be required by
the Plan Commission and Common Council in the vicinity of schools,
commercial areas and other places of public assemblage where the potential
pedestrian density may warrant, and the Council may require the construction
of sidewalks in locations other than required under the preceding
provisions of this chapter if such walks are necessary, in its opinion,
for safe and adequate pedestrian circulation.
When public sanitary sewer facilities are available to the subdivision
plat or certified survey map, the subdivider shall construct sanitary
sewerage facilities in such a manner as to make adequate sanitary
sewerage service available to each lot within the subdivision. When
only private sanitary sewer facilities are available to the subdivision
plat or certified survey map, the subdivider shall follow the rules
and restrictions of Waukesha County and Ch. SPS 383, Wis. Adm. Code.
In addition:
A.
All subdivisions and minor land divisions within the adopted sanitary sewer service area shall be provided with public sanitary sewer facilities, unless a waiver is granted by the Public Works and Safety Committee or Public Works and Development Director or designee in accordance with the procedures of Chapter 290, Sewers, of the City Code due to insufficient service.

except for the added cost of installing sewers greater than eight
inches in diameter which are necessary to serve tributary drainage
areas lying outside of the proposed subdivision, unless the over-sizing
is required to serve vacant lands owned or controlled by the subdivider
or adjacent landowner. In addition, the subdivider shall pay to the
City a sanitary sewer trunk line connection fee based on the added
cost of installing larger sewers in the total tributary drainage area
which shall be prorated in proportion to the ratio which the total
area of the proposed plat is to the total drainage area to be served
by such larger sewers.
A.
The subdivider shall construct stormwater drainage facilities adequate to serve the subdivision which shall include, but not be limited to, curbs and gutters, catch basins and inlets, storm sewers, road ditches, open channels, water retention structures, water detention structures, temporary sedimentation basins, and settling basins. All such facilities shall be of adequate size and grade to hydraulically accommodate the maximum potential volumes of flow and shall be so designed as to prevent and control soil erosion and sedimentation and to present no hazard to life or property. All stormwater drainage facilities shall be constructed in accordance with Chapter 309, Stormwater Management, of the City Code.
B.
The subdivider shall assume the cost of installing all storm sewers
within the proposed subdivision or minor land division, except for
the added cost of installing storm sewers greater than those which
are necessary to serve tributary drainage areas lying outside of the
proposed subdivision. In addition, the subdivider shall pay to the
City a storm sewer trunk line connection fee based on the added cost
of installing larger sewers in the total tributary drainage area which
shall be prorated in proportion to the ratio which the total area
of the proposed plat is to the total drainage area to be served by
such larger sewers.
C.
Copies of all DNR and United States Army Corps of Engineer permits
shall be submitted to the City prior to any construction or disturbances
of land.
When public water supply and distribution facilities are available
to the subdivision plat, the subdivider shall cause such water supply
and distribution facilities to be installed in such a manner as to
make adequate water service available to each lot within the subdivision.
The subdivider shall make provision for adequate private water systems
as required by the City in accordance with the standards of the Wisconsin
Department of Natural Resources and Department of Health Services.
In addition:
A.
All subdivisions and minor land divisions within the water supply
service area of the City shall be provided public water supply and
distribution facilities or community well facilities, unless a waiver
is granted by the Public Works and Safety Committee.
B.
The subdivider shall install water laterals to the street lot line
for all lots.
C.
Where a community well is approved by the Common Council as a water
distribution system for the subdivision, the developer shall require
the installation of water meters in accordance with the rules and
regulations of the City and the State Plumbing Code. The meter water
usage shall be the basis for establishing water rates in the subdivision.
D.
The size, type and installation of all public or private water mains
proposed to be constructed shall be in accordance with plans and standard
specifications approved by the Common Council.
E.
The subdivider shall assume the cost of installing all water mains,
water laterals and water system appurtenances within the proposed
subdivision except for the added cost of installing water mains greater
than eight inches in diameter. The added cost of water mains greater
than eight inches in diameter shall be borne by the City Water Utility.
A.
The subdivider shall cause gas, electrical power, cable television
and telephone facilities to be installed in such a manner as to make

land division. No such electrical, telephone or cable television service
shall be located on overhead poles. In addition, plans indicating
the proposed location of all such utilities shall be approved by the
City Engineer.
B.
All new electric or communication lines from which lots are individually
served shall be installed underground within all newly platted subdivisions
or minor land divisions unless the Plan Commission shall find that
the lots to be served by such facilities can be served directly from
existing overhead facilities. Associated equipment and facilities
which are pertinent to underground electric and communications systems,
including but not limited to substations, pad-mounted transformers,
pad-mounted sectionalizing switches and pedestal-mounted terminal
boxes, may be located above ground. Any landscape screening plan required
for such aboveground equipment shall be submitted to the affected
utilities for approval.
A.
Streetlamps and poles. The subdivider shall pay to the City the cost
to install streetlamps and lamp poles, of a design approved by the
City Engineer, at each subdivision street which intersects an arterial
or collector and at such interior block spacing as may be required
by the Common Council.
B.
Signs. The subdivider shall pay to the City the costs for installing
street signs of a design approved by the City Public Works and Development

conditions in terms of natural tree coverage. The Public Works and
Development Department shall maintain a list of approved street trees
for small and large planting areas.
(2)
Street tree planting shall be completed in accordance with the plans
and specifications approved by the Plan Commission and/or City Forester
and shall be warranted by the subdivider for 12 months following the
day of planting and the City Forester's initial inspection. Twelve-month
warranty may begin after the initial day of planting if the City Forester
is not notified in advance of the day of planting. In this case, the
twelve-month warranty begins the day the City Forester is notified
the planting has taken place and the initial inspection of that planting
has taken place by the City Forester.
(3)
The lot owner shall be responsible for all street tree maintenance
following the initial planting and twelve-month warranty period required
of the subdivider. The lot owner shall replace any dead or dying trees
per the original plans and specifications approved by the Plan Commission
and/or City Forester at the lot owner's full expense.
(4)
The subdivider shall submit a bond or letter of credit in an amount
determined by the City Engineer to cover the costs of trees, planting,
and maintenance for 12 months following initial planting. The bond
or letter of credit shall be in effect for 18 months following initial
planting and shall not be reduced or released until all required trees
have been inspected by the City and deemed to be in a healthy and
flourishing condition. Trees determined by the City to be dead or
dying shall be replaced at the subdivider's full expense.
Where a subdivision or minor land division abuts an existing
street or half street and lots within the subdivision or minor land
division access the existing street or half street, the subdivider
