With the approval of the Town Engineering Office and the Highway Superintendent, the Planning Board may waive the provision of any or all required improvements which in its judgment and considering the special circumstances of a particular plat or plats, are not required in the interests of the public health, safety and general welfare. For each waiver granted, the Planning Board shall enter upon the records its reasons why the particular improvement is not necessary and it shall attach appropriate conditions or require such guaranties as may be necessary to protect the public interest.
In order to prevent flooding, erosion or any other dangerous or hazardous condition from occurring during the progress and completion of required improvements, the Planning Board may require the developer or his agents to take any action, including the construction and/or installation of temporary facilities, as the Town Engineering Office may recommend. Such recommendations may not supersede state requirements under SPDES permit GP-02-01.
If at any time before or during the construction of the required improvements, the Town Engineering Office, the Highway Superintendent and the Planning Board determine that unforeseen conditions make it necessary or preferable to modify the location or design of any required improvements, the Town Engineering Office may, upon approval of the Planning Board and with the concurrence of the Highway Superintendent, authorize such modifications, provided they are within the spirit and intent of the Planning Board's prior approval and do not extend any waiver or constitute a substantial alteration of the function of any improvements required by the Planning Board. The Town Engineering Office shall issue any authorization under this section in writing and shall transmit a copy of such authorization to the Planning Board prior to its next regular meeting.
A. 
The required improvements shall not be considered to be completed until their installation has been approved by the Town Engineering Office and a map satisfactory to the Planning Board has been submitted indicating the location of monuments marking all underground drainage utilities as actually installed and the corners of all new lots created by the developer.

Where field conditions necessitate modifications to the approved road and drainage maps, the Town Engineering Office shall have the right to require amended maps for the public record.
C.
