The Conservation Administrator stated this is the vacant lot behind 5 John Hosmer Lane, lot 6. It has a shared driveway. The owners have sold both properties and the current owners want their parents to live behind the front lot. The order expires in November. They are working on their preconstruction items, one of the requirements was a conservation restriction. On a motion by Ms. Ladd and seconded by Ms. Dohan, the Commission voted 7-0 by roll call vote to extend the order of conditions to November 30, 2021. Record of vote as follows: Duke Bitsko —Aye Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye Philip Hamilton—Aye Approve the FY21 -FY26 Goal and Priority Setting Subcommittee recommended FY 2126 Goal and Priorities and FY 22-FY26 Capital Improvement Plan for budget development cycle Mr. Hamilton stated the priorities will determine the work of the Stewards over the next five years and highlight projects that will need funding. The Conservation Administrator stated there was one item that was left off. The last item on the chart under FY25 needs to have the cost of construction and it does not. FY26 needs to have the wetland delineation and survey on it. She will circulate an amended version. The Commission had no question regarding the priorities. On a motion by Ms. Dohan and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to approve the priorities. Record of vote as follows: Duke Bitsko —Aye Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye Philip Hamilton—Aye Chiesa Farm: fence update and approve removal Mr. Hamilton stated David Williams, the trustee, asked for permission to remove the fence that is part way up the hill. Mr. Williams provided an estimate of$3,700 to fix the gaps in the fence. At a previous meeting the Commission raised the concern of spending that money on a fence that would deteriorate in the future. Mr. Williams proposed to take it down and to save the pieces to repair gaps in the upper fence. The Commission agreed this proposal makes more sense. The Commission requested notices be sent out. On a motion by Ms. Ladd and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to allow Mr. Williams to remove the middle fence and use the wood to repair the upper fence with the understanding that public outreach will be done so people aren't surprised by the fence removal.

Documentation Submitted.- - ubmitted:- MassDEP Request for Determination of Applicability application dated 811512020 - Detailed Project Description, Plan, and Schematic Layout dated 811412020 Kathryn Flanagan, property owner of 119 Maple Street, presented before the Commission. She stated she has wetlands on two sides of her property and she maintains a buffer area that contains vegetative plantings. She wished to improve that area by removing a section of English Ivy and other invasive shrubs and replace them with native perennials and native shrubs. Concerns of the Commission: - There was mention of a fence falling down. This should be reflected for the record. - The procedure of the removal of the English Ivy and keeping it removed. - The dingo [Dingo: mini loader on rubber tracks for small landscaping projects] be refueled towards the front of the house to prevent runoff to the wetlands as it runs on gasoline. Responses of the Applicant: - If it is allowed they would like to remove the fence. It is a fallen down chain link fence. - The combination of removal by hand and replacing with other native plants. There might be the use of a"walk behind dingo". - Agreed. On a motion by Mr. Langseth and seconded by Mr. Bitsko, the Commission voted 7-0 by a roll call vote to issue a Negative Determination with conditions. Record of vote as follows: Duke Bitsko —Aye Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye Philip Hamilton—Aye ViewPoint Cloud 4CNOI-20-23, DEP 201-XXXX NOI, O Revere Street, Parker Meadow Conservation Area Applicant: Town of Lexington Project: Construction of an ADA universally accessible trail system and associated parking lot, boardwalks, and pond overlook platform Documentation Submitted.- - ubmitted:- MassDEP Notice oflntentApplication dated 811812020 - Project Plans dated 811 712 02 0 - Stormwater Management Report and attachments dated 812020 Kyle Zick, Landscape Architect with KZLA, presented before the Commission. He explained the plan. This request is because there was a petition to make the trails universally accessible. There is a small parking lot on Revere Street which will have improvements. The parking lot is a gravel parking lot and is in the riverfront area for the stream. There are invasive plant species along the trails. The parking lot has no storm water management right now and the water flows out toward Revere Street. They want to delineate the parking spaces, manage stormwater and get the parking all on town land. (The parking area presently encroaches on abutting property.) The trails and boardwalks will be made into an accessible trail system. The trails will have a crushed stone consistency. They will have an overlook of the pond. The Boardwalks will be five feet wide and some existing areas will be realigned. They will be doing Invasive vegetation management. They also plan to remove trees that are a hazard or are dead. They will cut and leave some trees at fifteen feet for habitat. In terms of the parking lot, the pavement material will be asphalt for the curb cut and travel lane, and the parking stalls will be permeable pavement which is FilterPave, a porous material made from recycled glass and stone. Everything drains off the asphalt into the permeable pavement. The Conservation administrator stated they have not received the memo from Engineering. Concerns of the Commission: - Calculation associated with stormwater management for the parking lot. - The invasive plant seed will remain in the soil for some time. How is the area being treated and how will the applicant avoid occurrences of the invasive species. - Was there anything learned from Cotton Farm in reference to the filter pave that should be considered? - Overview of construction schedule. - Describe a scenario where the parking stalls clog and where that water goes? - The size of the overlook area. - How will the entrance to Parker Meadow from the Minuteman Bikeway be closed? - Is there a plan for the following year to follow up with any invasive that resprout? - Snow plowing and removal. Response of the Applicant: - Full stormwater management report was submitted. - The Town does have a steward program and can do work here. The bid documents are not complete so that would need to be discussed. - The filter pave at Cotton Farm has not been in that long. They have learned the stone was a rounded stone and was slippery so a grip has been added. The stone selection should be angular. They had gravel to filter pave at Cotton Farm. - They would go out to bid November and would likely be a spring start. - If it were to clog it would revert to a typical impervious parking lot but it would take a lot of continued use without maintenance to hit that level. If there was clog to the point where the infiltration rate was impacted there would be more frequent over flows in a stable spot. If this is noted on a frequent basis they would do some filter work. It is still better than the existing condition. - The overlook is 15 ft by 10 ft. - It will not be closed, it just won't be improved. - That is typically what they do. - It would not be a high priority lot to plow, if the Town agencies had the time then it would be plowed. They would push the snow away from Revere Street toward the end of the asphalt. Concerns of Abutters: - Is the Commission aware of the changes in the pond over the last several years? The pond level has been reduced over the last several years. As a result there is no apparent inflow or outflow of water. - Confirm that access to the backyard of property owners on Revere Street will not be restricted by the parking lot improvements. Mr. Hamilton stated they are aware of the pond and it is something they will look into. Mr. Zick stated there will be no restrictions to those property owners. On a motion by Mr. Buettell and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to continue the hearing until September 21, 2020 at the applicant's request. Record of vote as follows: Duke Bitsko —Aye Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye ViewPoint Cloud 4CNOI-20-24, DEP 201-XXXX NOI, 43 Sanderson Road Applicant: Evan Freeman Property Owner: Michelle Yanetti Project: Construction of an expanded deck within the 100 foot Buffer Zone from a Bordering Vegetated Wetlands Documentation Submitted.- - ubmitted:- MassDEP Notice oflntentApplication dated 811812020 - Project Plans dated 1112712018 - Wetlands Delineation Report dated 1 011 712 01 7 - Buffer Zone Planting Plan dated 811312020 3 David Sperduto, Wetlands Identification Services, presented before the Commission. He stated this proposal is for the expansion of a deck and restoration of a buffer zone plant area. He explained the deck expansion plan. During the site visit the Commission commented about the existing deck area and proposed area so there is a revised plan. The proposed stairway does not extend past the existing stairway. The existing deck is 237 square feet and the proposed deck is 442 square feet. They are proposing to retain some native species, one plant they are asking the Commission to consider is a Rose-of-Sharon. It is not invasive. Hibiscus Species and the Rose Mallow Bee were discussed in terms of the Rose-of-Sharon being a hibiscus species. The Rose- of-Sharon is providing a food source for these Bees. Concerns of the Commission: - The prior deck had a condition that the stairs not point towards the wetland. Right now the stairway is proposed to point in the direction of the wetland. How big is the landing on the pea stone area at the bottom of the stairs? - What is the surface material between the pea stone and the wetland? Responses of the Applicant: - It is less than four feet. They could reconfigure the stairs so that they point to the left but the wetland is parallel to the house. The stairs are thirty feet from the wetland. When someone comes down the stairs they have a goal in mind. - It is lawn. Michelle Yannetti , homeowner of 43 Sanderson Road, stated they are working with the deck company to come up with other alternatives and they have come up with a couple of ideas. They are not in favor of those ideas but will keep working on it. Krisoula Vardoudakis, deck designer, presented before the Commission. She stated they did look through other options but any option added more footings and more deck space. It would be more invasive to the soils. On a motion by Ms. Ladd and seconded by Ms. Samuels, the Commission voted 7-0 by roll call vote to continue to the September 21, 2020 meeting at the applicant's request. Record of vote as follows: Duke Bitsko —Aye Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye ViewPoint Cloud 4CNOI-20-22 (Bylaw Only) NOI, 400 Shire Way Applicant: Takeda Project: Construct additional impervious surfaces outside wetland resource areas with applicable drainage connections Documentation Submitted.- - ubmitted:- MassDEP Notice oflntentApplication dated 811812020 - Project plans dated 811812020 - Stormwater Management Report with attachments dated 811812020 John Hart, SNMA on behalf of Takeda, presented before the Commission. He stated the addition is proposed to be 12,600 square feet, 105 by 120 ft. It is over an existing impervious surface. It will all be maintained. The existing recharge system will need to be removed and relocated. That will pick up all the roof drains from the existing building and the new roof addition. All the drainage work is kept within the parking lot except for structures out on the perimeter roadway and those are water quality units. There is a planting plan. There is an existing island which will change shape. In 2008 they had a NOL At that time they did permit an addition. He then showed the watersheds and basins based on the 2008 permit. In the filing they were slightly over the impervious area calculated but in fact they are under. Mr. Hart then discussed the Discharge runoff Summary and groundwater Recharge Volume. They will still maintain the bio retention area. There is a 50 percent TSS removal for the water quality unit. Concerns of the Commission: - Did the numbers for preexisting conditions reflect the current regulations with regard to how impervious areas are to be taken out of service should be created as open space and good condition in terms of the storm water calculations? The documentation should reflect the current regulations. - Confusion on the impervious surface document. - Is the current wetland detention consistent with the wetland delineation that was done 15 years ago? Responses of the Applicant: - The existing conditions modeling is the actual existing conditions now. They can provide that. - There was a figure of 1,903,301 square feet that was submitted in the original notice of intent and each project they have done they have come back and worked against that. They looked at the new addition and started new and came up with a number that was higher and then they designed to that. They had about 9,000 square feet that was analyzed as impervious but wasn't so they over designed the system. They can update those calculations. - It is consistent. On a motion by Ms. Samuels and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to continue to September 21, 2020, meeting at the applicant's request.

They were going to rotate the shed to take it out of the 50 foot buffer zone. Concerns of the Commission: - Stated there was a concern from the abutter about the plants that had been removed. - Calculations supporting storm water management. - The shed is listed as being 10 by 15. There is nothing showing this on the plan, nothing showing the stone. - The applicant should discuss the regulations with the Town Engineer. Responses of the Applicant: - There was a dead tree and that abutter had asked for it to be cut down. Happy to pass that request along to the owners. - The shed is 10 by 12. - At the last meeting there was no request for stone. Only to rotate the shed.
