Prior to or at the time of the request for the release
of performance guaranties, the applicant shall submit to the Board
three copies of as-built plans, including profiles and construction
details, bearing a certification by a registered land surveyor or
registered civil engineer that the location, material, elevation and
method of construction or installation of all streets, utilities,
stone bounds or other monuments, street signs and any other required
improvements conform exactly to the approved definitive plans, as
they may have been modified by the Planning Board, and to these rules
and regulations or indicating clearly any departures therefrom and
the actual as-built locations, materials, grades and other particulars
thereof. Work shall not be considered completed and performance guaranties
shall not be released until such certified as-built plans have been
received and the Board determines that any departures from the approved
plans and these rules and regulations are minor and nonsubstantive
or necessary and require no alterations.
