Conservation Commission Minutes 06/06/02


	Conservation Commission Meeting June 6, 2002 Peg Arguimbau Chairman, members Hank Langstroth, Peter Holden and Janet Dunlap were present. 7:50 p.m., N.O.I. Sharon School Dept., proposed construction of building additions totally 44,102 sq.ft. Construction of new parking facilities and drop-off loop; as well as associated sewer, water, electrical, gas & stormwater utilities at the Sharon Middle School. DEP# SE-280-426: David McKinley landscape architect from Kaestle Bros., Association, Inc. Manuel & Christopher Garcia engineers from Garcia, Galuska & DeSousa. Peter Collins program manager from Heery International, representing the Sharon Standing Building Committee, appeared before the Commission. David McKinley presented the architectural design to the Commission and stated that ample parking facilities are proposed as well as a separate bus drop-off loop. The Tennis Courts would be relocated. The soccer and baseball areas and the track and field areas would remain unchanged. Four courtyards would be part of the configuration of the proposed building and some of the courtyards would be used for infiltration into the ground. The proposed design of the building would not encroach on the surrounding wetland buffer. Manuel Garcia delivered his presentation on the improvements on the drainage and sewage design and presented the legal packet containing the green cards to the Commission. He explained to the Commission, and the abutters present (see attached list), that the new drainage and sewage systems for this proposed project would be more efficient than the current systems. The current drainage system consists of a network of pipes that travels its way through the site. Drainage from the football and track areas and a series of catch basins collects rainwater and eventually empties into the wetlands. The roof drains flow into the courtyard area into a series of pipes feeding into a trunk line. Mountain Street has a couple of drainage basins that flow into the site and empties into the wetland regime. All the drainage from this site is unmitigated and untreated and empties into the wetlands. He proposes to pump the sewage from this site to the existing Weston and Sampson Sewage Treatment Plant at the High School. This would be economical for the Town, and the increase in flow would make the treatment plant easier to operate. Installation of a water quality structure is proposed for the drainage that flows in from Mountain Road. All new drainage systems brought up to current standards are proposed for the new parking areas and driveways. Installation of new deep sump catch basins and water quality structures are proposed so that they can provide treatment to improve the current drainage system. Groundwater recharge is proposed in the courtyard area to accommodate the roof drains. An underground retention area will hold stormwater. All of the stormwater discharge points from the site will be cleaner and reduced by half. Greg inquired as to what route would the proposed sewer line be traveling. Manuel stated that the preliminary survey for the sewer line is to travel down Mountain Street, East Street, across Pond Street, up Beach Street, and by the ball field at the High School to the sewage treatment plant. (A separate filing will be made for the proposed new sewer line installation). Peg asked if the percentage of increase of impervious area has been calculated for the proposed project. Manuel estimated approximately 45%. Peter Collins mentioned that the proposed construction would not begin for a least one year. The School Committee and the Building Committee's vote of approval would be required and then the whole project would hinge on Town Meeting approval. Abutter Dave Wluka, 64 Massapoag Avenue, brought up a neighborhood issue regarding existing flooding conditions and inquired what efforts could be made to reduce the flooding. Manuel stated he would seek more drainage options before the next meeting. Peg called for a motion to continue the hearing until the July 11^th meeting at 7:45 p.m. Hank moved. Janet seconded. Voted. Unanimous. Page 2 SCC 6/6/02 Minutes 8:15 p.m. N.O.I. A.G.A. Inc. Proposed deck and swimming pool, Lot 2, Lou Stubbs Lane: Peg recused herself from the hearing and left the meeting room. Peter Holden recused himself, as he was an abutter when the development was built. Hank opened the Hearing and explained that due to the absence of a quorum, the Commission could only receive information regarding the proposed project and the Hearing would be continued. James Miller from Miller Engineering represented A.G.A. He explained to the Commission and to the abutters present (see list attached), that this is lot 2 of a 3 lot subdivision that is being constructed off of East Street. The house has been built and the prospective buyers' request is to have a pool and deck added in the backyard. James stated that he previously filed a RDA and the Commission reached a Positive Determination. Proposed is a 20'x30' swimming pool that is 25' from the edge of the 30' No Build Zone around the wetland area and a deck that is 28' long and 12' wide. The edge of the deck is approximately 59' from the No Build Zone. The pool is entirely in the Buffer Zone and the deck is partially inside the Buffer. (The edge of the house is a few feet outside of the 100' Buffer). All of the proposed construction is in the lawn area of the house. The haybale barrier is along the area of the No Build Zone. Most trees in that area have been cleared. Some grading has been done around the pool area. Hank inquired if James Miller could change the plans for the swimming pool The proposed 242 grade line is the limit of clearing around the pool. Abutter, Dennis Friedman, 6 Abbott Avenue, asked where the exact location of the house is in relation to the subdivision. Another abutter questioned if anything that is being proposed requires any changes to the shape or the capacity of the swale located on the south side of the lot. Hank stated that if the swimming pool were moved over to the north side of the lot, it then would be out of the way from the swale. Hank said that the Commission and Greg would like to inspect the site and requested that James Miller stake out the lower two corners of the deck. Hank stated that the Hearing would continue until June 20^th at 8:15 p.m. Janet made the motion to continue the Hearing until the 20^th of June. Hank seconded. Voted. 2-0-1. 8:30 p.m., RDA, 269 Mansfield Street. Driveway construction to proposed workshop. Linda and Chris Callan: Peg stated that there would be an informal discussion on what is being proposed and the Commission would officially discuss the proposed project on July 11^th when the paperwork is completed. Chris presented a plot plan and explained to the Commission that he is proposing to install a workshop type garage outside the Buffer Zone and is proposing to install a gravel driveway across the front of his house that would be inside the Buffer Zone. Peg stated that a Plan showing a sketch of the wetlands needs to be included in the filing and that the meeting would be continued until July 11^th at 8:15 p.m. No official statement was made. 8:40 p.m., Signatures: The Commission signed: Deed, AGA, Inc., Parcel "A" on Plan entitled "Willis Hanscom Estates" Definitive Subdivision.
