The developer shall install survey monuments placed in accordance
with the requirements of Ch. 236, Wis. Stats., and as may be required
by the Village Engineer/surveyor. The Village Board may waive the
placement of lot corner monuments until the submittal of the final
plat.
After the installation of survey control points by the developer and establishment of street grades by the Village Engineer, and unless otherwise stipulated by the Village Plan Commission, the developer 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 Village Engineer. The developer shall grade the roadbeds in the street rights-of-way to subgrade. Any way shall be graded to a maximum slope of three to one, or the soil's angle of repose, whichever is the lesser. All graded lands, with the exception of roadbeds of streets, shall be treated for sediment and erosion control purposes as set forth in §
330-64.
After the installation of all utility and stormwater drainage
improvements, the developer shall surface all roadways in streets
proposed to be dedicated to the widths prescribed by this chapter
and the other Comprehensive Plan components of the Village. Such surfacing
shall be in accordance with plans and standard specifications accomplished
in two lifts or layers of asphalt over a compacted layer of crushed
stone and approved by the Village Engineer and in conformance with
the adopted street construction standards of the Village and with
any developer's agreement. The cost of surfacing in excess of
48 feet in width that is not required to serve the needs of the land
division shall be borne by the Village or other unit or agency of
government having jurisdiction.
In all land divisions the Village Board may require the developer
to construct concrete curbs and gutters in accordance with plans and
standard specifications approved by the Village Board. In addition,
curbs and gutters are required by the Village Board on cul-de-sac
islands, on streets adjacent to uses which generate high volumes of
traffic (in excess of 1,500 ADT), and on streets where steep topography
conditions cannot be overcome by redesigning. 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 Village shall be borne by the Village or other unit
or agencies of government having jurisdiction.
When permanent rural street sections have been approved by the Village Board, the developer shall finish grade all shoulders and road ditches, install all necessary culverts at intersections, and, if required, surface ditch inverts or otherwise prevent erosion and sedimentation in accordance with plans and standard specifications approved by the Village Engineer and as set forth in §
330-64 and in the adopted Village design and construction standards.
The Village Board may require sidewalks if they are necessary,
in its opinion, for safe and adequate pedestrian circulation.
When it is proposed to establish a private sanitary sewer system
to serve two or more lots, the developer shall construct sanitary
sewer facilities in such a manner as to make adequate sanitary sewer
service available to each lot within the land division.
The developer shall construct stormwater drainage facilities
adequate to serve the land division, which may include curbs and gutters,
catch basins and inlets, storm sewers, road ditches, culverts, open
channels, water retention structures, and settling basins. All such
facilities shall be of adequate size and grade to hydraulically accommodate
the maximum potential volumes of flow through and from within the
land division and shall be so designed as to prevent and control soil
erosion and sedimentation and to present no hazards to life or property.
In addition:
A. Unpaved road ditches and back slopes shall be shaped and seeded and/or
sodded as grassed waterways. The bottom or V of all drainage channels
or ditches having a slope of 3% or more shall be sodded with grass
strips laid perpendicular to the slope of the drainage channel. Where
the velocity of flow is in excess of four feet per second on soils
having a severe or very severe erosion hazard and in excess of six
feet per second on other soils, the developer shall install a paved
invert or check dams, flumes, or other energy dissipating devices
as prescribed by the Village Engineer and Village Board.
B. Drainage facilities shall, if required, include water retention structures
and settling basins to prevent erosion and sedimentation where such
facilities discharge into streams or lakes. The design criteria, the
size, type, grades, and installation of all stormwater drains and
sewers and other cross section, invert and erosion control paving
check dams, flumes, or other energy dissipating structures and seeding
and/or sodding of open channels and unpaved road ditches proposed
to be constructed shall be in accordance with the design and construction
standards approved by the Village Board.
C. Where a sanitary or utility district has been created pursuant to
§ 60.70, Wis. Stats., for the purpose of providing and constructing
surface drainage facilities, storm sewers, or other drainage improvements,
such plans and standard specifications shall be further subject to
approval by the sanitary district board or commission.
D. The developer shall assume the cost of installing all storm sewers
within the proposed subdivision except for the added cost of installing
storm sewers greater than 24 inches in diameter which are necessary
to serve tributary drainage areas lying outside of the proposed land
division. In addition, the developer shall pay to the Village or sanitary
district wherein the land division is located 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.
When it is proposed to establish a private water supply and
distribution system to serve two or more lots, the developer 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 land division.
The developer shall cause electrical power and telephone facilities
and, where possible, natural gas to be installed in such a manner
as to make adequate service available to each lot in the land division.
No electrical or telephone service shall be located on overhead poles
unless otherwise allowed by the Village Plan Commission due to exceptional
topography or other physical barrier. Plans indicating the proposed
location of all gas, electrical power, telephone and TV cable distribution
and transmission lines required to service the plat shall be submitted
with the street plans and be approved by the Village Engineer. Such
utilities shall be constructed prior to Village Engineer approval
of final grading. Once installed, it shall be the responsibility of
the developer to complete or cause the completion of the restoration
of any lands disturbed by such installation to the satisfaction of
the Village Engineer.
The Village Board may require the developer to install streetlights. See Chapter
234, Lighting, Outdoor.
The Village Board shall require the installation of street signs
at the intersection of all streets proposed to be dedicated, and the
developer will pay for the cost of signs, plus the cost of installation.
The developer shall also be responsible for all permanent barricades
and regulatory traffic signs within the subdivision or minor land
division.
The Village Plan Commission may require a planting screen between
conflicting land uses, and/or to provide visual and sound screening
along arterial streets or highways. Such plantings shall be placed
by the developer within a designated planting easement of adequate
width, but not less than 30 feet, and shall conform to plans required
as a part of the preliminary plat submittal, which plans shall be
of sufficient accuracy and detail regarding height, size, and species
for review by the Village Plan Commission.
The developer shall plant those grasses, trees, and vines of
a species and size specified by the Village Board necessary to prevent
soil erosion and sedimentation. The Village Board may require, following
review and approval by the Village Engineer, the developer to provide
or install certain protection and rehabilitation measures such as
fencing, slopes, sodding and/or seeding, trees, shrubs, riprap, wells,
revetments, jetties, clearing, dredging, snagging, drop structures,
brush mats, willow poles, and grade stabilization structures. In addition:
A. Tree cutting and shrubbery clearing on wooded parcels shall be kept
to a minimum on the lot or tract and shall be conducted so as to prevent
erosion and sedimentation; preserve and improve scenic qualities;
and, during foliation, substantially screen the development from stream
or lake users.
B. Paths and trails in wooded and wetland areas shall not exceed 10
feet in width unless otherwise approved by the Village Plan Commission,
and shall be so designed and constructed to result in the least removal
and disruption of trees and shrubs, and the minimum impairment of
the natural beauty.
C. Earthmoving, such as grading, topsoil removal, mineral extraction, stream course changing, road cutting, waterway construction or enlargement, removal of stream or lake bed materials, excavation, channel clearing, ditching, drain tile laying, dredging, and lagooning, shall be conducted to prevent erosion and sedimentation and to least disturb the natural flora, watercourse, water regimen, and topography (see §§
330-63 and
330-64).
D. Review of the conduct of all cutting, clearing, and moving may be
requested of the county soil and water conservation district supervisors,
the state district fish and game managers, and the state district
forester by the Village Board or Village Plan Commission as it deems
appropriate.
