On a motion by Ms. Ladd and seconded by Ms. Dohan, the Commission voted 6-0 by 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—Recused Holly Samuels —Aye Phil Hamilton—Aye 7:01 PM 116 Vine Street: Notice of Intent ViewPoint Cloud Permit# CNOI-21-44, DEP#201-1246 Applicant: Lexington Housing Assistance Board, Inc. Project: construction of 40b housing consisting of two buildings (6 units), a parking lot and associated site development, within the 100-foot buffer to BVW Previous Meeting Date: 1212012021 Supplemental Documentation Submitted: — Supplemental Documentation Package and attachments; Prepared by: Hancock Associates; Date: 1/17/2022; — Permit Site Plan Set; Prepared by: Hancock Associates; Date revised: 1/17/2022; — Stormwater Report; Prepared by: Hancock Associates; Stamped and signed by: Brian G. Geaudreau, PE Civil No. 54495; Date revised: 1/17/2022; — Long Term Pollution Prevention Plan; Prepared by: Hancock Associates; Dated: 1/17/2022; Mr. Brian Geaudreau, Hancock Associates,presented to the Commission. Mr. Geaudreau stated that the test pit locations and proposed building overhangs are now shown on the site plan. Questions and Comments from the Commission: — What is the proposal for the northeast corner? Was a planting schedule submitted? — What is the steepest slope on the contours? — The proposal is disturbing significantly more than 50% of the natural community within the buffer zone. The Commission requires that the applicant submit a request for waiver in writing. — There is a lot of lawn on the steep slopes and would prefer to see those areas more natural. — The planting plan does not provide quantities or sizes of plants and that will need to be worked out since the proposal exceeds the allowed percentage of disturbance. — What do the dimensions of the rip rap, 9'x12', mean on the site plan? Responses from the Representative: — A planting plan has not been provided yet and Lexington Living Landscapes is helping with the preliminary landscape plan. — The steepest slope is 3:1 on the contours — Request a condition be added stating a more detailed planting plan be provided prior to construction — The rip rap stone will extend 9 feet out and be 12 feet in width at its furthest projecting point. Mr. Langseth stated that the Conservation Commission commonly requires overflows at the house and not from the underground structure itself, however it may be justified to have the overflow from the underground structure. It was stated that, on the right-hand side of the site plan, there is a significant slope going down towards the adjacent property. Mr. Langseth asked if there will be a Swale or retaining wall proposed to carry more runoff towards the back of the property. Mr. Geaudreau responded that a retaining wall is proposed three feet from the property line and the Swale will discharge any additional runoff. Mr. Geaudreau added that the land slopes from Vine Street to the wetlands so the existing contours will assist. Mr. Langseth said the plan should include contours showing that Swale. Mr. Matthew Barrett, son of the property owner of 132 Vine Street, stated that no runoff should go onto the property of 132 Vine Street, which abuts 116 Vine Street. The dwelling is very old and the proposal creates a lot of lawn area between the properties. A special condition will be added stating that any areas within the 100-foot buffer zone are required to be natural. On a motion by Mr. Langseth and seconded by Ms. Ladd, the Commission voted 6-0 by roll call vote to continue the hearing to the February 7, 2022 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 —Recused Phil Hamilton—Aye 7:33 PM 3 Goffe Road: Amendment to the Order of Conditions ViewPoint Cloud Permit#AOOC-21-11, DEP#201-1192, CNOI-20-21 Applicant/Property Owner: Lily Y Li Family Trust Project: after-the-fact approval for construction of landscape walls, sinks, island,patio and driveway resulting in an increase of 1,805 square feet of impervious surface within the 100-foot buffer zone to Bordering Vegetated Wetlands Previous Meeting Date: 11/22/2021 Supplemental Documentation Submitted: — Letter Describing Changes (43), 1/19/2022 — Revised Plot Plan, (43) 1/17/2022 — Stormwater Report(43) 1/17/2022 Ms. Maureen Herald, Norse Environmental Services, Inc., stated that the applicant is proposing to remove the 293 square feet of existing pavers within the 50-foot no build zone, and remove 70 square feet of patio walkway within the 50-foot no build zone to be replaced with open paver stone with grass. The applicant is also proposing to install a trench drain system directing to the cultec units and 166 square feet of additional patio surface outside the 50-foot no build zone. Questions and Comments from the Commission: — Want to see a detail for the grass pavers. — Don't want to have an overflow in an area that is easy to miss. Want the overflow at the downspout so any problems become obvious to the property owner. — Want to see an Operation and Maintenance Plan for the trench drain. Unsure of the functionality of a 112-foot trench drain over the long run. It was stated that this type of trench drain has a uniform depth and it doesn't look like the trench would bring water to the chamber system, and rather shed water to the sides of the house. The proposal will need a different kind of trench drain system or a different strategy to move the water. It was asked if there was an update on the fence encroaching onto land owned by the Town of Lexington-Bowman School. Ms. Herald responded that the property owner was attempting to purchase the area within the fence from the town in order to keep the fence where it is currently located. Mr. Beuttell informed the representative that, rather than proposing a trench drain to mitigate stormwater runoff, the applicant could capture an amount of roof runoff equal to that of the impervious patio runoff to meet the performance standards. Ms. Mullins added that the project is already capturing 475 square feet of roof runoff for the building addition. On a motion by Mr. Beuttell and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to continue the hearing to the February 7, 2022 meeting at the applicant's request.
