Asst. -- Present The duly posted meeting convened at 7:30 p.m. in room 105C. APPOINTMENTS: Ron Nations and George Connors P.E. were present to discuss the development plans for Norfolk Landing on River Road. Mr. Connors passed out copies of the revisions to the proposed 7 lot Open Space subdivision. The lots will be 40,000 square feet in area. Of the 12 acres, 4.5 acres will be open space. All pavement on the entire site will be removed. Approximately 74% of the site will be transformed from pavement to grass surface. The impervious area on the site will be reduced to 1.4 acres which will consist of roadway, driveways and houses. The zoned floodplain is at elevation 140 feet. The FEMA flood elevation is 138.2 feet. The applicant will use LID designs and a drainage swale. There will be rapid infiltration of stormwater runoff due to the sands and gravel on the site. All runoff will be directed to a rain garden/constructed wetland. Lot 4 appears to be within a buffer resource. The parcel currently is encumbered by two Orders of Conditions issued under the Chapter 40B filing. One Order dealt with a proposed detention basin and the other was for drainage discharge on Lark Road. The applicant will plan to amend the Order of Conditions for the detention basin while letting the Order of Conditions for the Lark Street drainage expire. Mr. Connors will be sending a letter to the Commission with their reasoning for requesting an amended Order of Conditions instead of submitting a new filing. Mrs. Terrio will draft a letter to the Planning Board on this project. Mr. Weddleton stated that he would attend a planning board meeting when they discuss the matter. PUBLIC HEARING: 7:55 p.m. 8 Stilwell Ave. – Request for Determination of Applicability. David Crossman from B&C Associates and Mr. and Mrs. Atwater were present. The RFD was filed to determine if a small depression in the rear yard is subject to jurisdiction under the Conservation Commission Minutes of May 12, 2010 2 Town of Norfolk Wetlands Protection Bylaw and Regulations, specifically Land Subject to Flooding by Surface or Groundwater. The property is located at the Norfolk/Medfield border. There is a man made ditch for runoff located on the Medfield property behind 8 Stilwell Ave. The depression area contains wetland vegetation but the soils are upland. Mr. Crossman noted that the groundwater is so high that there is groundwater breakout along the toe of the slope. The water table was found to be 16 inches in one perk hole and 20 inches in another hole. Mr. Crossman stated that this area is not bordering land subject to Flooding. He noted that neither wetlands nor the stream/ditch is shown on the U.S.G. S. maps. An upgraded septic system is being proposed, which will have to be a raised system. The house is serviced by a private well. The septic system cannot be located in the front of the house due to the location of the well. Ms. DeLonga stated that the area is question is about 2,700 square feet, which would be large enough to fall under the criteria for an ILSF. The wetland vegetation consists of Jack-in-the-Pulpit, Jewel Weed and Poison Ivy. Mr. Weddleton asked if the repair work could be done in the same footprint as the old system. The Commission recommended that the Applicants return to the engineer of record to see if the leach field could be located in another area. Mrs. Terrio recommended that more research be done before the Commission takes a vote on this matter. Mr. Crafton made the motion to continue the public hearing to May 26, 2010 at 8:00 p.m. Mr. Weddleton seconded the motion. The vote on the motion was unanimous.
