Mr. Dailey explained that the Attorney General and Town Meeting have approved the zoning changes that are required for the proposed assisted living facility expansion. Brookhaven is proposed to build 49 new units and they hope to begin in the fall of 2017. Mr. Dailey stated that in 2007/2008, the commission reviewed this property before and determined that the stream on site is an intermittent stream. Mr. Borabach stated that main areas of concern for the Commission are an intermittent stream that runs through the property and a certified vernal pool. The primary access to the new facility will be pass over an existing culvert that is in the intermittent stream. Mr. Borabach explained that they did explore the option of removing the culvert and installing a proper bridge crossing, but they were unsure of how this would affect the hydrology of the stream. The water and utility service will have to be routed under the stream. The engineering department will not allow them to run the utilities along the culvert. The stormwater design has three main points including a design point at a culvert, a detention basin, and a box culvert in the driveway. Two wetland replication areas are proposed along the side the culvert. The applicant has also removed the sidewalk along the vernal pool buffer. Questions and comments from the Commission: The commission stated that they would like more documentation regarding the status of the stream. The commission asked for more detail regarding the buffer disturbance calculations. The commission stated that they were concerned about the replication area being so close to the road. The commission asked for more detail regarding the trees that are proposed to be planted. The commission stated that they need more detail regarding the limit of work line. The commission asked for a sketch of what the culvert crossing will look like. The commission stated that they normally require overflows on the downspouts. Questions and comments from the audience: Malcom Kasparian, 956 Waltham Street, stated that he and other neighbors were concerned about increased flooding in the area. He also stated, that in previous hearings regarding this site in the back, there were questions over the status of the stream. A representative of the Lexington Elks Club, 959 Waltham Street, also stated concerns about increased flooding in the area. Mr. Borabach stated that there should be no difference in water flow on the site.
