beginning construction the applicant shall post a performance guarantee in the form of a bond or
escrow or other guarantee approved by the Planning Board for the amount to cover
decommissioning, including a 20% contingency and calculated with twenty -year inflation factor.
2. The Board must find that the removal of trees will not negatively impact the health, safet y and
welfare of the residents of Northampton by maintaining a robust and diverse ecosystem for the
residents while also creating renewable energy systems. In order for the Board to make such finding,
the applicant shall submit an analysis of the proposed project's impact relative to the benefit of the
solar installation as follows:
a. Analysis showing that tree removal which occurs on more than one acre of slopes greater than
20% will not cause erosion of topsoil and will not increase siltation of any streams present on
the site or within 200 feet of the property boundary.
b. Analysis of the forest type and relevant habitat that will be lost. This analysis must include the
structure and diversity of the canopy, midstory and understory of the forested area to be
cleared. Analysis must be performed by an individual with a master's degree in wildlife biology
or ecological science from an accredited college/university or other competent professional
with at least two years of experience in wildlife habitat evaluation.
i. Any forested area within which certifiable vernal pools are found must be i dentified and a
permit from the Conservation Commission must be granted prior to review by the Planning
Board.
ii. Any forested area containing clusters of five or more healthy trees of 20 inches diameter
breast height or greater that are not in decline shall be preserved in order to continue to
provide high value ecological benefit to the community. Connection of these larger trees to
surrounding stands of trees shall be maintained.
iii. As part of the forest type analysis, the report shall contain information re garding the
abundance and distribution of habitats within the region and of the specific site and any
historical information on the extent and quality of these habitats and impact of clearing on
these habitats. The applicant must show through analysis that habitat is not fragmented and
that connectivity remains in the proposed conditions.
c. Analysis by a qualified third party showing that the project will be carbon -neutral over the first 10
years of operation. The applicant shall provide the following calculations:
i. The total volume of trees to be removed (provided by an independent certified forester) and
the projected volume of trees over a ten-year period of additional growth.
ii. Subtracting the estimated live-wood in replacement trees provided under the significant
tree section of this zoning ordinance 10 years after planting.
iii. Conversion of the net live-wood to be removed to short tons of carbon (using research from
the Northern Institute of Applied Climate Science or other methodology after approval by
the permit granting authority).
iv. Subtraction of the carbon offsets (short tons of carbon) provided by the solar photovoltaic
project over 10 years of operation, including the calculation of potential carbon stored had
the trees continued to thrive in that same ten-year window. 350 Attachment 24:8 Supp 11.4,
May 2020 ZONING e. If there is any net release of carbon with the above calculations, the
applicant shall assign renewable energy credits (REC) to the City to match or exceed said
release of carbon. However, RECs may not be used to fund biomass projects.
d. At least 50% of the property shall be protected from tree clearing and future development for
the duration of the operation of the solar array installation and until such time as the system is
decommissioned and removed.
e. Within the area beyond the first two acres of canopy removed, stumps for removed trees must
remain in place and no excavation/soil disturbance is allowed other than what would be
required to bore support posts for the PV panels.
f. Electrical transformers for utility interconnections may be aboveground only if required by the
utility provider. Power and telecommunications poles and equipment shall not be visible from
the public way.
