A.
After construction is completed, the subdivider shall
request approval, in writing, of the work. The request shall be accompanied
by a sealed certification from the subdivider's engineer that he has
supervised and inspected all construction and that all work is in
accord with the approved plans and specifications.
(1)
Such certification shall include as-built plans where
revisions in the approved plan were required by conditions encountered
during construction.
(2)
As-built plans shall be submitted for sanitary sewers
and water mains. The location of all service Y's and laterals shall
be shown on the as-built plans. Service Y and lateral locations shall
be witnessed by a dimension, in feet, to the nearest downstream manhole
center or water main valve. Where a service lateral is extended from
a Y, the end of the lateral shall be witnessed by an appropriate dimension
and angle. In addition to witness measurements, a pressure-treated
two-by-four shall reach from the service lateral vertically to a point
two feet above finish grade.
B.
The Engineer and department heads shall inspect the work as soon as possible after the requirements of Subsection A are complete. If the work is complete and acceptable, recommendations shall be given to the Planning Board for acceptance by the village. If the work is not approved, the developer shall be notified as to deficiencies. A reinspection will be required if deficiencies are found.
