Strict compliance with the requirements of these rules and regulations may be waived only by a recorded vote of the Board, when, in the opinion of the Board, such action is in the public interest and not inconsistent with the Subdivision Control Law. All waiver requests shall be in writing and shall specify the section of these regulations for which a waiver is requested.
For matters not covered herein, reference is made to the Subdivision Control Law.
The applicant is responsible for ensuring all construction is properly inspected by the Board or its agent. Inspections shall be made by the Board or its agent to ensure that construction conforms to the approved plans. Copies of all inspection reports will be made available to the applicant. As a minimum, the inspections listed below shall be performed for all subdivisions. The order and number of inspections may vary or overlap depending upon site conditions. Adequate notification for inspection requests shall be given to the Board. Notification shall be a minimum of 48 hours (excluding Saturdays, Sundays and legal holidays) in advance of the time inspection is needed. Neither inspections by the Board or its agents nor inspections, tests or approvals by others shall relieve the owner from the owner's obligations to perform the work in accordance with the approved plans and these rules and regulations. Work that has been determined to be defective as the result of evidence discovered subsequent to opinions of conformance shall be corrected prior to final acceptance of the work at the owner's expense.
A. 
Clearing, grubbing and excavation. Inspection(s) shall be made of the work after clearing, grubbing and rough grading of the subdivision but prior to placement of any fill required for street or way construction. At this time any areas of unsuitable material for street or way construction will be identified for subsequent removal. Reinspections shall be made after removal of unsuitable material.
B. 
Fill. Inspection(s) of compacted fill in place shall be made. Fill may be tested for conformance of material and required compaction at this time. Fills placed in more than one lift may require multiple inspections.
C. 
Underground utilities. Regardless of the underground utility involved, the backfilling of all trenches requires inspection.
(1) 
Drainage.
(a) 
Outfalls of all drainage shall be staked with location and cut or fill to invert clearly marked thereon prior to any further drainage construction. Location and grade shall then be inspected by the Board or its agent for conformance with the approved plans.
(b) 
Inspection shall be made by the Board or its agent of all drainage pipe and structures prior to backfilling. Prior to inspection, grade and location stakes shall be provided or other arrangements made so that checks on elevation or location can be performed by one man.
(c) 
Inspection of castings shall be conducted prior to application of the surface pavement course.
(2) 
Sewer system. Inspection shall be made by the Sewer Department or its agent. Inspection shall be coordinated with the Board. No pipe or structure excavations shall be covered prior to inspection. Appropriate leakage tests for structures and pipes shall be made on all components of the sewer system. Appropriate field control shall be supplied to enable checking of grades and location by one man. If required by the inspector, water lines shall be uncovered at the owner's expense in the vicinity of the sewer system to verify that proper clearances have been maintained.
(3) 
Water system. Inspection shall be made by the Water Department or its agent. Inspection shall be coordinated with the Board. No pipe or structure excavations shall be covered prior to inspection. Appropriate leakage tests for pipes shall be made on all components of the system. Appropriate field control shall be supplied to enable checking of grades and location by one man. If required by the inspector, sewer lines shall be uncovered at the owner's expense in the vicinity of the water system to verify proper clearances have been maintained.
(4) 
Other utilities. Other utilities shall be inspected by the utility company with jurisdiction; however, the Board shall be given notice of such inspections as indicated above.
D. 
Trench backfill. Inspections shall be made on trench backfill for all underground utilities. Inspection shall be for conformance of material and compaction of material. Frequency of this inspection shall depend upon outcome of initial inspections and experience with contractor on this and other aspects of construction.
E. 
Roadway and sidewalk foundation. Inspection shall be for conformance of material and compaction of material. Samples of material in roadway and sidewalk foundation shall be taken for laboratory testing. Field compaction tests shall be performed on material taken from roadway foundation. Compaction tests shall be performed at least every 100 feet and at utility structures as required.
F. 
Bituminous concrete pavement. Inspection shall be made on the binder course and the surface course of roadway paving and the binder course and surface course of sidewalk paving. Ninety-six hours prior to placement of any material, the contractor shall submit to the Board or its agent for approval mix specifications, name of supplier of mix and name of subcontractor installing the mix. At the time of paving the Board may make any tests or take samples it deems appropriate to check conformance with the approved plans and these rules and regulations.
G. 
Curbing. Prior to backfill of granite curbing, an inspection shall be made.
H. 
Loam and seed. Prior to seeding loam shall be inspected for depth and material conformance.
I. 
Other improvements. Inspection(s) shall be made of all other improvements such as castings, grass plots, side slopes, monuments, street signs, lighting, street trees, walls, guardrails, etc., for conformance with the approved plans. Timing of inspection(s) shall be as required to ensure proper inspection.
J. 
Final inspection(s). Inspection(s) shall be made of the entire work including cleanup. If items of nonconformance are discovered, they shall be listed by the Board and a reinspection of the subdivision shall be made. Reinspection will not be limited to listed items; if evidence of faulty or substandard construction appears between inspections it shall be listed and must be repaired. At the time of request for final inspection, the contractor shall present the following:
(1) 
Copies of written approvals for underground utilities inspected by other agencies. Said approvals shall be in a form acceptable to the Board.
(2) 
As-built plans (three sets) indicating as-built locations of all monuments and structures, said plans to be stamped by a Massachusetts registered professional land surveyor and in a form acceptable to the Board.
A. 
Inspectors or agents shall render opinions to the Board on conformance of work inspected with approved plans. Inspectors or agents designated by the Board do not have the authority to waive any requirements of the approved plans unless such authority is granted to them by the Board. Inspectors may interpret plans when requested by the contractor; such interpretation shall be made either verbally or in writing.
B. 
Inspectors or their agents may offer opinions to the Board regarding changes required to be made in the field due to errors in the original approved plans or errors made during construction. Such opinions shall be made solely as a means of expediting resolution of a problem and shall not be construed as authorization to proceed with changes or modifications to the approved plans. The Board is the only body empowered to allow modification of the approved plans; any conditions that require modification shall be presented to the Board for approval. Any deviations from the approved plans constructed without approval of the Board are constructed at the owner's risk and shall be removed and replaced at his own expense if deemed unsatisfactory by the Board.
