The planset was revised so that the wooden steps exiting from the rear wood deck would be outside of the 50-foot no build zone as it was in the initial proposal. Mr. Kirby stated that overall there will be a reduction in impervious surface area. Ms. Samuels, referring to the erosion control at the end of the driveway, stated that the site plan shows filter sock going over the driveway and down to the lot of the abutting property. Mr. Capachietti responded that he will move the filter sock off of the driveway and more towards the proposed pool area. Ms. Ladd asked if there are any demarcations shown for the edge of the Conservation Restriction and stated that it appears there is proposed landscape within the area. Ms. Mullins and Commission members agreed that there should be Feno markers in place to prevent encroachment and Ms. Mullins stated that there may be encroachment as it is. Mr. Kirby stated that he did not propose a landscaping plan as the area around the pool is currently disturbed, however would be replacing with native and non-invasive species. Ms. Ladd responded that the Commission needs to know and approve what the proposed planting would be. Mr. Beuttell requested that more detail be added to the Utility and Grading Plan to clearly show that any surface runoff will flow to the drainage areas around the pool and not down the slope or elsewhere. Mr. Capachietti agreed and will complete that for the next meeting. On a motion by Ms. Ladd and seconded by Ms. Dohan, the Commission voted 6-0 by roll call vote to continue the hearing to the March 15, 2021 meeting at the applicants request. Record of vote as follows: Kevin Beuttell—Aye Alex Dohan—Aye Ruth Ladd—Aye David Langseth—Aye Holly Samuels —Aye Phil Hamilton—Aye 7:31 PM ViewPoint Cloud Permit# CN0I-21-6, DEP#201-1211 Notice of Intent: Valleyfield, Grassland and Waltham Street, Right of Way Applicant: Town of Lexington DPW Project: Drainage improvements to the Valleyfield and Grassland Street Neighborhood and the replacement of a deteriorating culvert at Waltham Street. Documentation Submitted.- - ubmitted:— Notice of Intent application and attachments; Prepared for: Lexington Department of Public Works; Prepared by: Woodard and Curran; Dated February 2021; — Permitting Set; Prepared by: Woodard and Curran; Stamped and signed by: Denise L. Cameron, PE Civil No. 53548 and Michael J. Carter, PLS No. 48373; Scale: 1"=20' and as noted not to scale; Dated February 2021; — Engineering Memo from Marissa Liggiero, Engineering to Karen Mullins, Conservation; RE: 0 Valleyfield St NOI Comments; Dated: 2/23/2021 Mr. Michael Sprague, Town of Lexington DPW, and Ms. Denise Cameron, Project Manager at Woodard and Curran, presented before the Commission the proposal to address localized flooding in the Valleyfield, Grassland and Waltham Street neighborhoods by drainage improvements and replacement of a deteriorating culvert at Waltham Street. Questions from the Commission: — Is it possible to take out the culvert under the farm road entrance and instead place a natural channel underneath a bridge? Response from the Representative: — A natural channel would need to be maintained because the town would consider any passage over it to be a bridge and would not want to be responsible for maintenance. Have to suggest that a culvert is more applicable in this case. Ms. Donna Hooper, abutter at 50 Valleyfield Road, asked for Ms. Cameron to provide a more detailed explanation of where the pipes will drain into and asked if the brook size will accommodate this drainage flow. Ms. Cameron responded that the drainage at the Valleyfield Street and Grassland Street intersection will still drain at the same start and end points, and discharge through a 42 inch outlet into Clematis Brook. Ms. Cameron clarified that there are no new discharges, only an increase in the size of the system so it has more capacity to accept the discharge without causing problems or changes to the Brook. Mr. Matt Kiernan, abutter and property owner of 49 Valley Field Street, asked the representative if repairs will be made to the properties once the work is complete. Mr. Kiernan added that he had a conversation with town staff about two years ago and was told any damage to his property caused by necessary project would be repaired. Mr. Sprague responded that all Mr. Kiernan stated holds true and they intend to use the same landscape architect as was discussed. On a motion by Ms. Samuels and seconded by Ms. Ladd, the Commission voted 6-0 by roll call vote to close the hearing.
