Gary Trendel - Expires 2022  OSPC - Jane Moran - Expires 2024  TCMC - Dave Paul - Expires 2022    2    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.    2.3.Relevant Materials  ●Email from K.

 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.     2.5.Public Hearing Outline

Sediment shall be removed from silt  fence prior to reaching the load-bearing capacity of the silt  fence which may be lower than ¼ to ½ the height.  d.Sediment from sediment traps or sedimentation ponds shall  be removed when design capacity has been reduced by 50  percent.   e.Soil stockpiles must be stabilized or covered at the end of each  workday. Stockpile side slopes shall not be greater than 2:1. All  stockpiles shall be surrounded by sediment controls.   f.Disturbed areas remaining idle for more than 14 days shall be  stabilized with seeding, wood chips, bark mulch, tarpaulins, or  any other approved methods.  g.For active construction areas such as borrow or stockpile  areas, roadway improvements and areas within 50 feet of a  building under construction, a perimeter sediment control  system shall be installed and maintained to contain soil.   h.A tracking pad or other approved stabilization method shall be  constructed at all entrance/exit points of the site to reduce the  amount of soil carried onto roadways and off the site.  14  i.Permanent seeding shall be undertaken in the spring from  March through May, and in late summer and early fall from  August to October 15. During the peak summer months and in  the fall after October 15, when seeding is found to be  impractical, appropriate temporary stabilization shall be  applied. Permanent seeding may be undertaken during the  summer if plans provide for adequate mulching and watering.   j.All slopes steeper than 3:1 (h:v, 33.3%), as well as perimeter  dikes, sediment basins or traps, and embankments must, upon  completion, be immediately stabilized with sod, seed and  anchored straw mulch, or other approved stabilization  measures. Areas outside of the perimeter sediment control  system must not be disturbed.   k.Temporary sediment trapping devices must not be removed  until permanent stabilization is established in all contributory  drainage areas.   l.All temporary erosion and sediment control measures shall be  removed after final site stabilization. Disturbed soil areas  resulting from the removal of temporary measures shall be  permanently stabilized within 30 days of removal.  3.A minimum of seven days prior to the start of construction, a  detailed construction sequence shall be submitted to the Principal  Planner by the site contractor for review and approval.
