The subdivider shall construct streets, roads and alleys as outlined on the approved plans based on the requirements of this chapter, particularly §§
512-39 and
512-40:
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 City Engineer
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. All survey monumentation located adjacent to street
or public rights-of-way, but not located within street pavement, shall
be protected with steel fence posts erected near the survey monumentation.
The City Engineer may waive the placing of monuments for a reasonable
time during public improvement construction on condition that the
subdivider executes a surety 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 City Engineer. 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 an 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, installing curb and gutter, 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 City Engineer. 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
City Engineer.
Pursuant to §
512-43, 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 City Engineer. Only where sump pumps are required, storm sewer laterals of the sizes and materials required by the Director of Public Works or City Engineer 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 City Engineer. 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 City 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.
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 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 §
512-21B.
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 City Engineer'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 City Engineer to be feasibly
accessible.
The subdivider shall be required to grade the full land division in accordance with the requirements of §
512-45.
