The subdivider shall construct streets, roads and alleys as outlined
on the approved plans based on the requirements of this chapter:
A. General considerations. The streets shall be designed
and located in relation to existing and planned streets, to topographical
conditions and natural terrain features such as streams and existing tree
growth, to public convenience and safety, and in their appropriate relation
to the proposed uses of the land to be served by such streets.
B. Construction standards. Construction of all streets shall
conform to the current standards as established by the City in this chapter
and elsewhere and shall be subject to approval of the Public Works Director
before acceptance.
C. Conform to Official Map. The arrangement, width, grade
and location of all streets shall conform to the Official Map.
D. Survey monumentation. Before final approval of any plat
or certified survey within the corporate limits of the City, the subdivider
shall install monuments placed in accordance with the requirements of Ch.
236, Wis. Stats., or as may be required by the Public Works Director. All
survey monumentation located adjacent to street or public rights-of-way, but
not located within street payment, shall be protected with steel fence posts
erected near the survey monumentation. The Public Works Director may waive
the placing of monuments for a reasonable time during public improvement construction
on condition that the subdivider executes a survey to insure the placing of
such monuments within the time required. On behalf of the City, the City Clerk
is authorized to accept such surety bonds and contracts for monumentation
in an amount approved by the Public Works Director. Building permits shall
not be issued until all survey monumentation for the block(s) of lots in which
the lot(s) for which building permits are being applied for within the phase
of the land division under development has been installed. When the land division
includes and established 1/2, 1/4, 1/4 — 1/4, or such other
section monument, the established monument shall be preserved and/or fully
restored by the subdivider at his cost.
E. Street construction. After the installation of all required
utility and stormwater drainage improvements, the subdivider shall prepare
for surfacing all roadways in streets proposed to be dedicated, to the widths
prescribed by these regulations, by placing crushed rock on said roadways
and, in addition, shall surface said street, in a manner and quality consistent
with this chapter and plans and specifications approved by the Public Works
Director. Construction shall be to City standard specifications for street
improvements.
F. Street cross sections. When permanent street cross sections
have been approved by the City, the subdivider shall finish grade all shoulders
and road ditches, install all necessary culverts at intersections and, if
required, surface ditch inverts to prevent erosion and sedimentation in accordance
with plans and standard specifications approved by the Public Works Director.
After the installation of all utility and stormwater drainage improvements,
the subdivider shall be required to construct concrete curbs and gutters or,
if approved by the City, a system of ditches and culverts, in accordance with
City standard specifications. The subdivider shall install concrete curb and
gutter along both sides of all streets and boulevards shown on the plat. The
cost of the curb and gutter required inspection, supervision and engineering
fees shall be paid for by the subdivider. 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
shall be borne by the City. The size of culverts to be provided shall be determined
by the Public Works Director. All culverts shall be of corrugated steel pipe.
Pursuant to §
474-43, the subdivider shall provide stormwater drainage facilities which include curb and gutter, manholes, catch basins and inlets, storm sewers, storm sewer laterals from the main to the lot line, road ditches and open channels, as may be required. All such facilities are to be of adequate size and grade to hydraulically accommodate maximum potential volumes of flow, the type of facility required, the design criteria and the sizes and grades to be determined by the Public Works Director. Storm sewer laterals of the sizes and materials required by the Public Works Director shall be installed from the mains to the lot line of every lot in the subdivision when storm sewer mains shall be required by this section. Storm drainage facilities shall be so designed as to present no hazard to life or property, minimize shoreland erosion and siltation of surface waters, shall prevent excess runoff on adjacent property and shall provide positive drainage away from on-site sewage disposal facilities. The size, type and installation of all stormwater drain and sewers proposed to be constructed shall be in accordance with this chapter and plans and standard specifications approved by the Public Works Director. 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 Public Works Director. 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.
The subdivider may be required to install street lamps along all streets
proposed to be dedicated of a design compatible with the neighborhood and
type of development proposed. Such lamps shall be placed as may be required
by the Public Works Director.
The subdivider shall arrange with the City and pay the costs of providing
the street signing necessary to serve the development. Such signing shall
include street name signs and such temporary barricades and "road closed"
signs as may be required by the Public Works Director until the street improvements
have been accepted by Common Council resolution.
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.
When any public improvements of adequate capacity are not available
at the boundary of a proposed land division, the City, or its duly authorized
representative, shall require, as a prerequisite to approval of a final plat
or certified survey map, assurances that such improvement extensions shall
be provided as follows in accordance with the following standards:
A. Design capacity. All improvements within or entering
or leaving the proposed development shall be installed to satisfy the service
requirements for the entire service or drainage area in which the development
is located and the improvements shall be of sufficient capacity to handle
the expected development of the overall service area involved.
B. Extra-sized and off-size improvements. Where improvements of adequate size needed to serve the development are not available at the boundary of the development, the subdivider shall proceed under one of the alternatives as identified in §
474-22A.
C. Lift stations. Where sanitary or storm sewer lift stations
and force mains are required to lift sewage to the gravity system, the subdivider
shall have plans, profiles, specifications and estimated operation and maintenance
costs prepared for the installation of such facilities to the Public Works
Director's requirements. Equipment similar to existing City equipment shall
be utilized whenever possible. The installation, inspection, supervision and
engineering fees for lift stations and/or force mains shall be paid for by
the subdivider unless otherwise determined and agreed upon by the Common Council.
Gravity sanitary sewer service shall be employed whenever determined by the
Public Works Director to be feasibly accessible.
