2. The Northampton Stormwater Authority or its authorized representative shall be provided
access to the property to conduct inspections before, during, and after construction
activities as necessary. The applicant shall arrange with the Stormwater Authority to
schedule the following inspections: Erosion Control Inspection, Bury Inspection of
subsurface systems, and Final Inspection at the completion of work. The Stormwater
Authority may also conduct random inspections to ensure effective control of erosion and
sedimentation during all phases of construction.
3. The permittee shall be responsible for inspections of the construction of the stormwater
management system. The permittee shall retain a Project Engineer (the design engineer
or another professional engineer of record in the Commonwealth of Massachusetts) to
document the construction of the proposed stormwater system and site development
during all phases of the project as required in Section 12.3.1 of the Stormwater
Management Regulations. All proposed changes to the approved stormwater facilities
and site development shall be documented by the Project Engineer and submitted to the
Stormwater Authority for review and approval by the Stormwater Authority prior to
construction. The Project Engineer shall notify the permittee and the Stormwater
Authority wherein the work fails to comply with the Stormwater Management Plan as
approved. The approved plans shall be maintained at the site during the progress of the
work.
4. Prior to issuance of a final certificate of occupancy and within six (6) months after the
completion of construction and land disturbance activities, the permittee must submit an
As-Built Report and certified As-Built Plans both signed and sealed by a Registered
Professional Engineer (PE) licensed in the Commonwealth of Massachusetts (one hard
copy and one electronic copy). The as-built report shall certify that the stormwater
management facilities have been constructed in accordance with the approved
Stormwater Management Plan, the conditions of the approved Stormwater Management
Permit and any modifications to the plan approved by the Stormwater Authority. The as-
built report must include an inspection of the stormwater management system consistent
with the annual report required by the Stormwater Management Operation, Maintenance
and Inspection Agreement for the project, confirmation that the stormwater management
system has been cleaned of all sediment of debris and certification that the stormwater
management system is functioning as designed. The as-built plans must depict all
structural and non-structural stormwater management systems, including subsurface

components, impervious and pervious surface areas on site, elevations, inverts, grading,
materials, plantings, stormwater storage volumes, discharge points, layout, specification
of proprietary stormwater structures and other critical details of the stormwater
management systems and any easements obtained. Any discrepancies from the approved
Stormwater Management Plan should be noted in the as-built report. The Stormwater
Authority shall review the as-built plans and notify the permittee of any deficiencies with
the plan and compliance issues with the constructed stormwater management systems.
5. Prior to issuance of a final certificate of occupancy and within six (6) months after the
completion of construction and land disturbance activities, the permittee shall record the
as-built plans as approved by the Stormwater Authority and any accompanying
stormwater easements at the Hampshire District Registry of Deeds and provide a receipt
to the Stormwater Authority certifying this action.
6. Prior to issuance of a final certificate of occupancy and within six (6) months after the
completion of construction and land disturbance activities permitted under a Stormwater
Management Permit, the permittee must submit in writing a request for a Stormwater
Management Certificate of Compliance (SMCC). The request shall include the following
certification: "I hereby certify that all construction, development, and/or re-development
has been completed in accordance with the project application and approved plans and all
information is truthful to the best of my knowledge. The Stormwater Authority or its
authorized agent may conduct inspections whenever necessary to determine compliance
with the provisions of the Stormwater Management Permit, all applicable requirements of
the Stormwater Management Ordinance and the Stormwater Management Regulations.
Furthermore, I acknowledge that I am now responsible for the long-term operation and
maintenance of all stormwater management facilities. During a transfer of ownership, I
am responsible for informing prospective new owner(s) of the requirements of the
Stormwater Management Operations, Maintenance and Inspection Agreement." The
permittee must complete Standard Permit Conditions 4 and 5 before the Stormwater
Authority will consider the request for a SMCC.
7. The landowner, its successors and assigns, including any homeowners association, shall
adequately maintain the stormwater management facilities in good working condition and
in compliance with the Stormwater Management Operation, Maintenance and Inspection
Agreement filed at the Hampshire Registry of Deeds (see Specific Condition 1 below).
Annual Reports documenting the actions completed as required by the Stormwater
Management Operation, Maintenance and Inspection Agreement shall be submitted to the
Northampton Stormwater Authority by January 1st of each year.
8. The construction activities shall begin within three years after issuance of the Stormwater
Management Permit. If the project does not begin within three years, the permittee must
request an extension from the Stormwater Authority. If the project has changed, revised
plans and documents must be submitted to the Stormwater Authority for review. The
Stormwater Authority may grant an extension, at its discretion, to the three-year time
limit on a Stormwater Management Permit. If the project has changed in a substantive
way, a new Stormwater Management Permit may be required.

Specific Permit Conditions:
1. Prior to the start of construction and issuance of a Building Permit, the applicant shall
record an executed Stormwater Operation, Maintenance, and Inspection Agreement that
is binding on all subsequent owners of land served by the stormwater management
facility by recording it in the land records of the Hampshire Registry of Deeds. The
maintenance schedule and responsibility for maintenance of all components of the
proposed stormwater management system must be adequately specified in Attachment A
to this Agreement. The draft Long-Term Pollution Prevention Plan and Stormwater
Operation and Maintenance Plan submitted as part of the Stormwater Report must be
revised to the satisfaction of the Stormwater Authority for use as Attachment A to the
Agreement. The Stormwater Authority can provide additional guidance on required
revisions to the maintenance schedule. The final agreement shall be approved by the
Stormwater Authority and signed by the owner and the Mayor of Northampton. The final
agreement shall be recorded at the Registry of Deeds at the owner’s expense. Section 8.6
of the Northampton Stormwater Management Regulations provides additional guidance
for the requirements of this agreement.
2. A copy of the final Stormwater Pollution Prevention Plan (SWPPP) shall be submitted to
the Northampton DPW for approval prior to the start of construction and prior to issuance
of a building permit.
3. Construction plans and specifications shall be submitted to the Stormwater Authority for
approval prior to issuance of a building permit and prior to the start of construction.
4. The proposed stormwater management system is designed to mitigate stormwater flows.
If, after construction of the proposed project and stormwater system, the site is found to
increase stormwater flows or pollutants in these flows to adjacent properties, roadways
and stormwater systems, the owner shall redesign and reconstruct the stormwater
management system to prevent any increased stormwater flows or pollutants in these
flows to adjacent properties, roadways and stormwater systems.
