The Hearing was to hear and discuss a stormwater management special permit under Ch. 204 of the Code of the Town of Lunenburg for a 2.4 MW photovoltaic system located at 190 Electric Avenue , (Map 077, Parcel 0014), Lunenbu rg, MA. Applicant- Borrego Solar Systems, Inc. 55 Technology Drive Suite 102, Lowell, MA. Property owner - Lunenburg Solar LLC, 259 Turnpike Road Suite 100, Southborough, MA. The applicant was represented by Brandon Smith, Borrego Solar Systems, Inc. The project was permitted by the Board in 2019. They hope to pull a building permit this year, hence the st ormwater permit application. The stormwater permit application was reviewed by Graves Engineering, Inc. (GEI) in letter dated June 3, 2020 . Borrego responded to that review in letter dated June 8, 2020 received in the Planning Office after the close of business. P. Bertram inquired of any changes to stormwater since the Board’s approval in March 2019. Borrego noted slight changes had been made upd ating calculations based on field observations. P. Bertram also inquired what type of stormwater structure this would be classified as under the Stormwater Handbook. Borrego responded a dry detention basin; within 72 hours of a storm ===PAGE 2=== 190 Electric Avenue, Borrego Solar Minutes 06.08.2020 Page 2 event the basin is supposed to be dry. The dry detention basin is to the south with a swale running to the north. The outlet structure is a culvert. Since the 2019 approval Borrego has done more tree surveyin g. As a result, some of the areas of wooded cover have been fine-tuned. Consequently the basin has been slightly enlarged and is now approximately 35 X 55 square feet. There is a large rip rap area to slow down the flow. Post construction/ post stabilization is a grass field. When it rains, the rain will be diverted to the basin. The goal is to ensure there is not a large quantity of water coming off the site. The basin will catch some of the water to cut down the peak flow. During construction, washing and refueling of vehicles w ould take place; most likely in the turnaround area on the east side of the site. P. Bertram had concerns with this due to the limited decontamination of stormwater in this plan. Borrego responded this would take place in an upland area and be surrounded by erosion control measures. P. Bertram noted those measures are not indicated on the plan. The plan will be updated to indicate same and re-reviewed by GEI. T. Cole questioned what updates had been made based on field observations. Borrego d etermined there was a slight modification to what was actually on site. The HydroCAD model was modified for more accuracy as to what was actually on site. There was no change to the tree clearing lines. The property line was also fine-tuned. P. Bertram made Motion to continue the stormwater permit hearing for 190 Electric Avenue to June 22, 2020, 6:35 PM, T. Cole Seconded, Roll Call Vote- T. Cole, aye; P. Bertram, aye; M. Allison, aye.
