least 14 days prior to the hearing. The Conservation Commission shall
be responsible for posting the notice at the Town Hall. The applicant
shall be responsible for publishing the notice in the local newspaper
and for notifying abutting property owners, by certified mail, return
receipt requested. Copies of the certified mail receipts shall be
submitted to the Conservation Commission for verification prior to
opening the public hearing. The Conservation Commission shall make
the application available for inspection by the public during regular
business hours at the Town of Mansfield Conservation Office.
H. Action. The Conservation Commission may:
(1) Approve the application and issue a permit if it finds that the proposed
plan will protect water resources and meets the objectives and requirements
of this bylaw;
(2) Approve the application and issue a permit with conditions, modifications
or restrictions that the Conservation Commission determines are required
to ensure that the project will protect water resources and meets
the objectives and requirements of this bylaw; or
(3) Disapprove the application and deny the permit if it finds that the
proposed plan will not protect water resources or fails to meet the
objectives and requirements of this bylaw. If the Conservation Commission

or alteration is significant, based on the design requirements listed
in Part II or Part III of the regulations adopted by the Conservation
Commission under this bylaw, the agent of the Conservation Commission
may require that an amended application or a full application be filed
in accordance with this section. If any change or alteration from
the land disturbance permit occurs during land-disturbing activities,
the agent of the Conservation Commission may require the installation
of interim erosion and sedimentation control measures before approving
the change or alteration.
The erosion and sediment control plan shall contain sufficient
information to describe the nature and purpose of the proposed development,
pertinent conditions of the site and the adjacent areas, and proposed
erosion and sedimentation controls. The applicant shall submit such
material as is necessary to show that the proposed development will
comply with the design standards and contain the information listed
in the regulations adopted by the Conservation Commission for administration
of this bylaw.

plan shall fully describe the project in drawings and narrative. The
applicant shall submit such material as is required by the regulations
adopted by the Conservation Commission for the administration of this
bylaw.
The Conservation Commission may require the permittee to post, before the start of land disturbance activity, a surety bond, irrevocable letter of credit, cash, or other acceptable security. The form of the bond shall be approved by Town Counsel, and be in an amount deemed sufficient by the Conservation Commission to ensure that the work will be completed in accordance with the permit. If the project is phased, the Conservation Commission may release part of the bond as each phase is completed in compliance with the permit, but the bond may not be fully released until the Commission has received the final report and as-built plan as required by §
185-26 and issued a certificate of completion.
Upon completion of the work, the permittee shall submit a report
(including certified as-built construction plans) from a professional
engineer (PE) or professional land surveyor (PLS) certifying that
all erosion and sediment control devices, and approved changes and
modifications, have been completed in accordance with the conditions
of the approved permit. Any discrepancies should be noted in the cover
letter. In addition to a paper copy of the as-built construction plan,
one digital file shall be submitted in AutoCad DWG; but DXF format
will be acceptable. The media shall be 3.5 inches floppy disk or CD.
