are required as a condition of approval of a land division. The required
improvements described in this chapter shall be installed, furnished
and financed at the sole expense of the subdivider. However, in the
case of required improvements in a commercial or industrial area,
the cost of such improvements may, at the sole discretion of the Town
Board, be financed through special assessments.
B.
General standards. The following required improvements in this chapter
shall be installed in accordance with the engineering standards and
specifications which have been adopted by the Town Board. Where standards
and specifications have not been adopted, the improvements shall be
made in accordance with good engineering practices, approved prior
to the start of construction by the Town Engineer.
A.
Contract. Prior to installation of any required improvements and
prior to the meeting at which the final plat is approved, the subdivider
shall enter into a written contract with the Town requiring the subdivider
to furnish and construct said improvements at his sole cost and in
accordance with plans and specifications and usual contract conditions,
which shall include provision for inspection of construction details
by the Town Engineer.
B.
Financial guarantees.
(1)
The agreement shall require the subdivider to make an escrow deposit
or in lieu thereof to furnish an irrevocable letter of credit, the
amount of the deposit and the penal amount of the bond to be equal
to 120% of the Town Engineer's estimate of the total cost of the improvements
to be furnished under the contract, including the cost of inspection
or otherwise determined by the Town Board.
[Amended 3-13-2019 by Ord. No. 1]
(2)
On request of the subdivider, the contract may provide for completion
of part or all of the improvements covered thereby prior to acceptance
of the plat, and in such event the amount of the deposit, letter of
credit shall be reduced in a sum equal to the estimated cost of the
improvements so completed prior to acceptance of the plat only. If
the required improvements are not complete within the specified period,
all amounts held under deposit or letter of credit, shall be turned
over and delivered to the Town and applied to the cost of the required
improvements. Any balance remaining after such improvements have been
made shall be returned to the owner or subdivider. The Town Board,
at its option, may extend the deposit or letter of credit, period
for additional periods not to exceed two years each period.
[Amended 3-13-2019 by Ord. No. 1]
(3)

requirements of this chapter and other pertinent Town ordinances and
design standards recommended by the Town Engineer and approved by
the Town Board. If the Town Engineer rejects the plans and specifications,
he shall notify the owner, who shall modify the plans or specifications
or both accordingly. When the plans and specifications are corrected,
the Town Engineer shall approve the plans and specifications for transmittal
to the Town Board. The Town Board shall approve the plans and specifications
before the improvements are installed and construction commenced.
C.
Construction and inspection.
(1)
Prior to starting any of the work covered by the plans approved above,
written authorization to start the work shall be obtained from the
Town Engineer upon receipt of all necessary permits and in accordance
with the construction methods of this chapter. Building permits shall
not be issued until all improvements required by this chapter are
satisfactorily completed.
(2)

all street construction shall be completed by the subdivider, approved
by the Town Engineer and accepted by the Town Board. Contractors who
damage Town roads during construction shall be liable for such damage.
(2)
The Town Board may issue a waiver of these requirements in unusual
or special circumstances such as excessively severe weather conditions,
heavy construction temporarily in area or construction material shortages
(i.e., cement, asphalt). The issuance of a waiver shall be at the
discretion of the Town Board.
(3)
The subdivider requesting a waiver shall do so, in writing, presenting
such information and documentation as required by the Town Board.
The waiver shall be in written form and shall detail which improvement
requirements are temporarily waived and for what period of time.
After the installation of all required utility and stormwater
drainage improvements, the subdivider, when required by the Town Board
where determined to be necessary by the Town Engineer, shall construct
concrete curbs and gutters in accordance with plans and standard specifications
approved by the Town Board or its designee. Wherever possible, provision
shall be made at the time of construction for driveway access curb
cuts.
Sidewalks may be required by the Town Board in high traffic
areas and areas in the vicinity of schools, commercial areas and other
places of public assemblage. The Town Board may require the construction
of sidewalks if such walks are necessary, in their opinion, for safe
and adequate pedestrian circulation.
A.
There shall be provided a sanitary sewerage system in conformity
with the master plan of sewers as approved by the Town Board and/or
sanitary district.
B.
The subdivider shall make adequate sewage disposal systems available
to each lot within the subdivision, certified survey parcel or land
division.
C.
Subdivisions and certified survey parcels in a designated urban service
area shall be served by public sewer facilities. The size, type, and
installation of all sanitary sewers proposed to be constructed shall
be in accordance with plans and specifications approved by the appropriate
sanitary district.
D.
Land divisions created by certified survey outside areas served by
public sewer service may be served by private sewage disposal systems,
if public sewer facilities are not available. Private sewage disposal
systems shall comply with the rules of the Department of Safety and
Professional Services contained in Ch. SPS 385, Wis. Adm. Code, and
with the Jefferson County Sanitation Ordinance. Service laterals shall
be provided to all lots served by public sewer.
[Amended 3-13-2019 by Ord. No. 1]
E.
The subdivider shall pay all the costs of all sanitary sewer work,
including the bringing of the sanitary sewer from where it exists
to the subdivision in question, as well as providing all sanitary
sewer work within the subdivision. The size, type and installation
of all sanitary sewers proposed to be constructed shall be in accordance
with plans and standard specifications approved by the appropriate
sanitary district serving the area.
A.
The subdivider shall make adequate domestic water supplies available,
and pay for such improvements, for each lot within the subdivision
or land division in a designated urban service area.
B.
The subdivider shall construct water mains in such a manner as to
make adequate water service available to each lot within the subdivision
or land division. The size, type, and installation of all public water
mains proposed to be constructed shall be in accordance with plans
and specifications approved by the appropriate sanitary district.
Water service laterals shall be provided to all lots served by public
sewer.
A.
The subdivider must prepare a stormwater drainage plan containing the matters set forth in Subsection B that is approved by the Town and its engineer unless the Town waives such requirements in writing. The stormwater drainage plan may not be amended without the consent of the Town.
B.
Pursuant to § 490-37, the subdivider shall provide stormwater drainage facilities which may include curb and gutter, catch basins and inlets, storm sewers, road ditches and open channels, as may be required. Storm sewers are to be of adequate size and grade to hydraulically accommodate the ten-year storm; culverts shall be designed to accommodate the ten-year storm and shall be sized so that the twenty-five-year frequency storms do not cause flooding of the adjacent roadway. Upon the approval of the Town Engineer, stormwater swales and ditches may be sized for from twenty-five-year to one-hundred-year frequency storms, depending upon the estimated amount of damage that would be incurred by adjacent properties if flooding did occur. Storm drainage facilities shall be so designed as to minimize hazards to life or property, and the size, type and installation of all stormwater drains and sewers proposed to be constructed shall be in accordance with the plans and specifications approved by the Town Board, upon the recommendation of the Town Engineer. Storm sewers oversized to handle runoff from off-site properties will be installed by the subdivider; however, the cost of oversizing above a twenty-four-inch diameter storm sewer shall be paid by other users connecting to the system.
A.
The subdivider shall cause gas, electric power and telephone facilities
to be installed in such a manner as to make adequate service available
to each lot in the subdivision, certified survey or land division.
All new electrical distribution television cables and telephone lines
from which lots are individually served shall be underground unless
the Town Board specifically allows overhead poles for the following
reasons:[1]
(1)
Topography, soil, water table, solid rock, boulders, or other physical
conditions would make underground installation unreasonable or impractical;
or
(2)
The lots to be served by said facilities can be served directly from
existing overhead facilities.

and telephone distribution and transmission lines required to service
the plat shall be approved by the Town Board and such map shall be
filed with the Town Clerk.
The subdivider shall install all necessary traffic control signs
and at the intersections of all streets proposed to be dedicated,
a street name sign of a design and installation specified by the Town
Engineer.
Pursuant to the County's or Town's Construction Site Erosion
Control Ordinance, the subdivider shall cause all gradings, excavations,
open cuts, side slopes, and other land surface disturbances to be
mulched, seeded, sodded or otherwise protected so that erosion, siltation,
sedimentation and washing are prevented. The subdivider shall submit
an erosion control plan that specifies measures that will be taken
to assure the minimization of erosion problems.
When the land included in a subdivision plat or certified map
abuts upon or is adjacent to land used for farming or grazing purposes,
the subdivider shall erect, keep, and maintain partition fences, satisfying
the requirements of the Wisconsin Statutes for a legal and sufficient
fence, between such land and the adjacent land. A covenant binding
the developer, its grantees, heirs, successors, and assigns to erect
and maintain such fences, without cost to the adjoining property owners,
so long as the land is used for farming or grazing purposes, shall
be included upon the face of the final plat or certified survey map.
A.
Utility easements. The Town Board, on the recommendation of appropriate
agencies serving the Town, shall require utility easements for poles,
wire, conduits, storm and sanitary sewers, gas, water and head mains
or other utility lines. It is the intent of this chapter to protect
all established easements so as to assure proper grade, assure maintenance
of the established grade, prohibit construction of permanent fences
or retaining walls over underground installation and prevent the planting
of trees in the easement area. The Town shall have access to the easement
to maintain if the develop and/or property owner fail to.
[Amended 3-13-2019 by Ord. No. 1]
B.
Drainage easements. Where a subdivision is traversed by a watercourse,
drainage way, channel or stream:
(1)
There shall be provided a stormwater easement or drainage right-of-way
conforming substantially to the lines of such watercourse and such
further width or construction, or both, as will be adequate for the
purpose and as may be necessary to comply with this section; or
(2)
The watercourse, drainage way, channel or stream may be relocated
in such a manner that the maintenance of adequate drainage will be
ensured and the same provided with a stormwater easement or drainage
right-of-way conforming to the lines of the relocated watercourse,
and such further width or construction, or both, as will be adequate
for the purpose and may be necessary to comply with this section.
(3)
Wherever possible, it is desirable that drainage be maintained by
an open channel with landscaped banks and adequate width for maximum
potential volume flow. In all cases, such watercourse shall be of
a minimum width established at the high-water mark or, in the absence
of such specification, not less than 30 feet. If, in the opinion of
the Town Engineer, the easement will be for a major drainage swale,
the easement shall be of sufficient width to contain a one-hundred-year
frequency storm. If the drainage easement is located in an established
floodway or flood fringe district, the entire floodplain area shall
be included within the drainage easement.
C.
Easement locations. Such easements shall be at least 12 feet wide,
or wider where recommended by the Town Engineer, and may run across
lots or alongside of rear lot lines. Such easements should preferably
be located along rear lot lines. Evidence shall be furnished the Plan
Commission and Town Board that easements and any easement provisions
to be incorporated in the plat or in deeds have been reviewed by the
individual utility companies or the organization responsible for furnishing
the services involved.
