1.1.Discussion of Solar Overlay Town Meeting Article As mentioned at the previous meeting,it was determined that the assumption
that the Frankland Road Solar project was grandfathered with regard to the overlay district due to the timing of the application,was incorrect.To be
grandfathered,a permit needs to be issued prior to the notice of the hearing, not the application being submitted.As this was a reason explicitly stated during
the discussion of removing this lot from the map,it was felt that the Board should understand the situation and be given the opportunity to come back to
this map and make a determination as to whether the Town Meeting Article moves forward as recommended,gets unnoticed and revised,or potentially gets
withdrawn entirely and remanded to ZAC for further review.
1.2.Legacy Farms Road South Trees Dave Paul asked to discuss this issue as he noticed two dead trees in the area
that should be addressed.
1.3.Board Appointments 1.3.1.Zoning Advisory Committee
Madhu Chandrasekar,Ria McNamara,and John Coutinho have applied to be reappointed to ZAC.John Coutinho does not need to be reappointed

Board.
1.3.3.Other Board Appointments Three other liaison or representative positions are appointed by the
Planning Board:Community Preservation Committee,Open Space Preservation Commission,and Trail Coordination and Management
Committee.The representatives to these three boards are still within their terms, as follows:

2.0 0,71 Frankland Road -Solar Special Permit and Stormwater Management Permit -
Seaboard Solar - PB-SPPT-2020-01 and PB-SMP-2020-01
2.1.Background
The proposed development is for a commercial solar photovoltaic installation at
0 and 71 Frankland Road,the former Liberty Mutual site.The development
parcel was recently subdivided through the ANR process,sectioning off the
existing structure and surrounding land from the rest of the property.The
proposed solar site is located on the westernmost parcel of the two,which is ±69
acres of mostly undeveloped forest land,a parking area (used for testing by
Liberty Mutual),and a 30-foot wide gas transmission easement.A portion of the
lot is located within the WRPOD,which may require a Special Permit from the
Zoning Board of Appeals.
At the time of the application,the proposed total site disturbance is ±28 acres,
which is mainly composed of tree clearing.The Applicant asserts that ±60%of
the site will be maintained as undeveloped land.
The proposed solar array is ±5.0 megawatts covering an area of ±28 acres.
Access will be gained via a gravel access road connecting to Frankland Road.The
array will be surrounded by this gravel access road and a security fence.
Portions of the limit of work are located within the wetland buffer area,however,
it appears that no panels will be located within the buffer to on-site wetlands.
Nevertheless,the project will require approval from the Conservation
Commission as well.
2.2.Regulatory Review
Commercial Solar Photovoltaic Installations are regulated under Article XXXI,
§210-200 of the Zoning Bylaw.Stormwater Management Permits are regulated
under Chapter 172 of the General Bylaws.
§210-201. Applicability
The installation of a solar facility is permitted in any zoning district provided they
are allowed through a Special Permit issued by the Planning Board.
§210-202. Use Regulations
Conformance with the zoning dimensional requirements is detailed below.
Agriculture (A) District Professional Office (P) District
Dimension Required Provided Required Provided
Min. Lot Size 3 acres ±69 acres 5 acres ±69 acres
Front Setback 60 feet ±283 feet 60 feet ±283 feet
Rear Setback 30 feet 98.7 feet 100 feet 98.7 feet
Side Setback 30 feet 61 feet 50 feet* 50 feet
3
Max Lot
Coverage 25% TBD 60% TBD
Frontage 200 feet Not
applicable** 50 feet ±970 feet
*The side setback in the P District is taken from parking areas or buildings in relation to the
adjacent zoning district. As the P District is not co-terminus with the side lot lines, a sliver of the
property to the west of the site is within the P District, while the rest of the lot is within the A
District.
**The frontage for the lot is wholly located within the P District, therefore that standard applies.
It appears that the rear setback is not met, as the P District is coterminous with
the rear lot line, requiring a 100-foot rear setback. Lot coverage is not calculated
based on the zoning district and is therefore necessary in order to determine
conformance with the Zoning Bylaw.
As set forth in the Zoning Bylaw, the project is not subject to site plan review.
Chapter 172, Stormwater Management and Erosion Control The proposed work must comply with the Stormwater Regulations,adopted in
2008 and revised in 2014.

2.4.Comments Received
Principal Planner Comments: 1.Provide calculation for lot coverage for both the A District and P Districts,
as applicable. 2.Reduce the northmost section of the array to meet the minimum
required setback for rear yard, as it abuts properties within the A District. 3.Provide visual depictions of the view from Fawn Ridge and Frankland
Street. Provided 4.Provide evidence of agreement with Eversource to perform work within
the easement on-site.Conditioned in the Stormwater Management Permit
4
5.Has there been consideration of raising the bottom of the fence by at
least 6”to accommodate travel of wildlife in,out,and around the fenced
area during operation of the array?
6.What type of vegetation is included in the Ernst Solar Farm Seed Mix?Do
the plants included in this mix flower at less than 12”in height?I would
suggest seeding of the land with a pollinator-friendly mix or other wildlife
mix to encourage use of the land as a meadow,if this mix does not
accomplish this.
