All plats and subdivisions shall meet the following
requirements:
A. Water supply and sewage disposal.
(1) All water and sewage lines to be installed shall be
constructed to the property line, before the streets are built.
(2) Where an approved public water supply or sanitary
sewer is not located in proximity to a subdivision, any private system
shall meet the requirements as to standards, specifications, construction,
supervision, and maintenance as specified in the Grant County Private
Sewage System and Sanitation Ordinance.
B. Drainage.
(1) Provision shall be made for the adequate disposal
of surface water either to a natural drainage course or to a storm
sewer system, as approved by the County Engineer.
(2) All surface drainage facilities shall connect to an
adequate drainage course.
(3) Land that is subject to flooding periodically shall
be provided with such improvements as may be required to remove flooding
hazards from proposed subdivision lots.
The subdivider shall install monuments in accordance
with the requirements of § 236.15, Wis. Stats.
The developer may apply for final approval and
recording of all or only part of the entire subdivision. The improvements
specified shall be installed and approval of the final plat shall
be given only after the work has been completed or there shall have
been filed with the Planning and Zoning Committee one of the following:
A. A duly completed and executed surety bond in an amount
sufficient to complete the work with surety satisfactory to the appropriate
municipality or the Planning and Zoning Committee.
B. A certified check, in an amount sufficient to complete
the work, drawn on an approved bank and available to the appropriate
municipality or the Planning and Zoning Committee. As the work progresses
the municipality or the Planning and Zoning Committee may permit the
exchange of said check for another check of sufficient amount to complete
the remaining improvements agreed upon. If the improvements are not
completed within the specified time, the municipality or Planning
and Zoning Committee may use the bond or the certified check to complete
the remaining work provided for.
C. Other collateral satisfactory to the appropriate municipality
or the Planning and Zoning Committee in an amount sufficient to complete
the work.
