Engineering reports, construction plans and specifications. Preliminary
engineering plans shall be submitted with the filing of the preliminary
plat. At the final plat stage, or before construction begins, plans
for the required improvements, conforming in all respects with the
standards of the Village and Village Engineer and the ordinances of
the Village, shall be prepared at the land divider's or subdivider's
expense by a professional engineer registered in the State of Wisconsin,
under said engineer's seal. Such plans, together with the quantities
of construction items, shall be submitted to the Village Engineer
for approval and for estimation of the total cost of the required
improvements; upon approval, they shall become part of the required
public improvement agreement. Simultaneously with the filing of the
final plat with the Village, or as soon thereafter as practicable,
the subdivider shall furnish copies of the construction plans and
specifications.
