NEW MEETINGS/HEARINGS 6:51pm DEP 201-1055, BL 1012 NOI, Pleasant Street Applicant: Town of Lexington, Engineering Owner: Town of Lexington and Wilson Farm Project: Construct sidewalk and modify drainage infrastructure Dave Pavlik- Town Engineer, Denise Cameron- Woodard and Curran Mr. Pavlik explained that as part of a drainage study of the Town, Pleasant Street was identified as a flooding concern. They are proposing to daylight a stream to alleviate the some of the flooding issues. Ms. Cameron stated that Woodard and Curran did a hydrologic study in the area to determine the cause of the flooding. It was concluded that the inlet pipe is undersized; it is currently12 inches, but should be 24inches. The first phase of the project would be to resize the inlet pipe to an appropriate size. If this does not alleviate the flooding, the will move onto phase two. If needed, phase two would involve re-sizing the stream channel under the road. Currently the stream is in a conduit that drops in diameter from 42 inches to 24 inches. Phase two will only be done if phase one is not successful. Additionally, she stated that they are looking at alternatives to a riprap slope; currently they are thinking about using bionet. They are going to cascade the plants on the slope as well. They are also going to do some invasive species removal. Questions and comments from the Commission: The commission asked for clarification regarding the phasing of the project. Ms. Cameron explained that right now they are seeking approval of only phase one. If phase two is needed, they will come back before the Commission. The commission asked if the hydrologic survey relied on phase two. Ms. Cameron explained that the survey did not identify phase two as a necessary step. Motion to close the hearing made by Mr. Wolk and seconded by Mr. Beuttell. Vote: 5-0 in favor.

Since the last meeting, the applicants have changed their plans so they no longer require Zoning Board approval. The sports court has been reduced in size and the shed has been relocated. Mr. Kirby clarified that the shed is going to be a simple garden shed with a utility sink. The planting plan has also been updated. Questions and comments from the Commission: The commission asked for clarification regarding the stormwater system for the shed. Mr. Capichetti said that all runoff will be collected to the pervious patio and infiltrate through that. At the request of the Commission he said he will do additional test pits in that area. The commission asked for clarification between the discrepancies in the site plan and planting plan. Mr. Kirby explained that the planting plan is for planting purposes only. The planting plan was made before the site plan was revised. The commission asked for an alternatives analysis because the project is within the 100 ft. inner riverfront zone, and is not an exempt project because it proposes work within the 50ft. buffer to the river. The Applicant agreed to provide the alternatives analysis. Motion to continue the hearing to 5/1/2017 at the applicant’s request made by Mr. Wolk and seconded by Mr. Beuttell.

The Lincoln side of the project is much more complex and he will need more time to do a full review and comparison. Mr. Nyman explained that at this point, his best recommendation would be for more test pits to be done in the area of the turf field. The applicant agreed to this.

Mr. Garvin explained that they need that road to service the existing day care center on the adjacent property.
