Bolton Conservation Commission Minutes of Meeting March 6, 2007 PRESENT: Scott Duhaime, Sarah Greenough, Kevin Lord, Lori Stephenson, and Administrator Carol Gumbart. Kevin Lord, prospective member. 1. Town of Bolton, Wastewater Treatment Facility (112-517) Scott Duhaime opened the continued hearing on the Notice of Intent proposing to install sewer lines through wetland and adjacent upland resource areas associated with a new Wastewater Treatment Facility for the Town of Bolton. Christine Chestna of Tata and Howard was present to represent the Town along with Bill Spratt, of the Wastewater Treatment Facility Committee and school representative. Martha Remington was present representing the Bolton Historical Commission. Ms. Chestna said that the Town Administrator, Jodi Ross and Selectmen, Ken Troup have an agreement from Flatly to access the site from their parking lot. Ms. Chestna said they propose to lay 100 feet of pavement at the beginning of the access and the 100 feet of gravel with turn off areas. Ms. Chestna said the remainder will follow the existing cartroad. Carol Gumbart asked if any of this work would be within a resource area? Ms. Chestna said they will evaluate this. Ms. Remington asked why the stone wall was not shown on the plans? Ms. Remington said she has not received the ground penetration study but the former site of William Sawyer Farmstead dating back to 1670 is near the break in the stone wall. Ms. Chestna said that they are proposing to cross the existing culvert by laying down steel sheeting. Ms. Chestna said this is a temporary measure. Ms. Chestna said that the Army Corps of Engineering (ACOE) has approved the stream crossing for the sewer pipes. Ms. Remington asked if there will be trees cut for the crossing. Ms. Chestna said trees will be cut and she said that the two 10” pipes will be laid 20 feet away from the causeway. Ms. Chestna said the trench for the pipes is three feet wider than the diameter of the pipe. Ms. Remington said that the channel in this area is stone lined on the east side of the brook. Ms. Chestna said that the earthwork specs require restoration to original conditions. Ms. Remington question why the pipe was not being jacked under the stream rather that dug through it. Ms. Chestna speculated that it is cost prohibitive to jack the pipe. Ms. Chestna said they have received approval from ACOE, the MA Natural Heritage and Endangered Species Program (NHESP) and the MA Historical Commission. Ms. Chestna said the findings from NHESP is for Blue Spotted Salamander and that they need to avoid impacts during migration. Ms. Chestna said they have hired a wildlife biologist to develop a plan for “critter gaps”. Ms. Chestna said the consultant will develop a barrier plan to comply with the NHESP conditions of approval. Mr. Duhaime said the Commission is looking for the plans to be updated to show (1) a wetland delineation in the vicinity of the access road adjacent to Flatly; (2) the Barrier Plan; (3) location of the historic structure; (4) a tree cutting plan; and (5) the stone wall. Mr. Duhaime said the Commission also wants specifics on the road layout and an Operation and Maintenance Plan for the road. Ms. Gumbart asked if the building footprint was being enlarged. Ms. Chestna said they are adding another membrane but the manufacturer is still reviewing the DEP requirements and she does not know if the building footprint needs to be enlarged yet. With the consent of the applicant’s representative the hearing was continued to April 3, 2007, at 8:30 pm. Bolton Conservation Commission Minutes March 6, 2007 page 1 2. Skinner, Lot 1 Burnham Road (112-527) Scott Duhaime opened the continued hearing on the Notice of Intent proposing to construct a driveway and new single family home on Lot 1 Burnham Road. Present for the hearing were Brandon Ducharme of Ducharme and Dillis Civil Design Group, (CDG) and resident Rodney Ramirez. Mr. Ducharme said that he attended a site walk with commission members Sarah Greenough, Kevin Lord, Scott Duhaime and Dan Gaffney (Bolton Conservation Trust Director and trail committee volunteer). Mr. Ducharme said that the Commission looked at the wetland on the north side of the site and were satisfied with the delineation. Mr. Duhaime said the site had lots of white pine, was fairly level and part of the property was in a meadow condition. Mr. Duhaime that Mr. Gaffney was interested in a trail that runs through the property. Mr. Ducharme said that the Natural Heritage and Endangered Species Program (NHESP) issued a letter saying that the project would not result in “a take” and there would be no adverse impact to the habitat of the Marbled Salamander. Mr. Ducharme said the letter is confusing in that it references the Skinners other property and project for the new warehouse. Mr. Ducharme said that he spoke with Sarah Haggerty of NHESP and this will be corrected. Carol Gumbart asked if the Commission was concerned with the encroachment of the yard around the house in the Riverfront Area. Ms. Greenough said the Commission discussed having a wood rail fence along the edge of the driveway. Ms. Gumbart asked if there is proposed mitigation of for the alteration of 4910 square feet of RFA. The Commission discussed an interest in keeping the meadow maintained as a meadow. Ms. Gumbart said she understood that the owner might be giving a conservation restriction on some of the land. Mr. Ducharme said that he has heard this but he does not have anything definitive yet. Mr. Ducharme said that the owner is still in the preliminary stages of developing and protecting the land. Ms. Gumbart suggested that the Commission could impose a condition that requires that within three years a permanent conservation restriction be provided as mitigation or a mitigation plan be submitted. The Commission also discussed the need to have a permanent barrier along the edge of the landscape yard. The Commission suggested that rocks, vegetation important to wildlife and fencing can be used to blend into the natural landscape. The Commission requested an estimate for the construction of the driveway for escrow security. Mr. Ducharme said he would provide this. The Commission recapped saying that they would like to see the meadow north of the driveway mowed occasionally. Ms. Gumbart said that an issue came up when this land was surveyed and they found that Mr. Ramirez’s septic system was installed on Nancy Skinner’s Lot 1. Mr. Ramirez said that this was done prior to his purchasing the property. Ms. Gumbart said that this is going back to the Board of Health for consideration. With the consent of the applicant’s representative, the hearing was continued to March 20, 2007. 3. Curran, Lot 5 Corn Road (112-520) Scott Duhaime opened the continued hearing on the Notice of Intent proposing to construct a driveway for access to a new single family home. No one was present for the hearing. Carol Gumbart said she spoke with the applicant, John Curran, and he said he had not received any communication from the MA Natural Heritage and Endangered Species Program (NHESP). Ms. Gumbart recommended that the Commission consider adding a condition to the Order of Conditions that requires the owner to comply with any conditions imposed by the NHESP. Ms. Gumbart said that she received the construction estimate and asked if the Commission would require the 1.5 times the cost or if they might top it at $20,000.

Mr. and Mrs. Lupo presented photographs of Ms. Bagdonas’ property taken during on March 2, 2007, while it was raining. Ed Englemann said that the driveway is either contributing sediment or there is an imminent threat of doing so. Kevin Lord said that the condition of the driveway has deteriorated and could use regravelling, which could reduce the threat of sediment being washed down the driveway. After discussion the Commission requested that Carol Gumbart send Elizabeth Bagdonas a letter right away asking her to install the erosion controls as required in their prior correspondence and to file an application by April 1, 2007. The Commission asked Ms. Gumbart to include a copy of their enforcement procedures with the letter and to refer to the photographs submitted by the Lupos. 5. Henderson, 8 Rocky Dundee Road (112-392) Scott Duhaime said he met with Chris Rogers at the site and found the work generally incompliance with the approved plan. Mr. Duhaime said the differences were that instead of planting trees to close the gap to the well from the lawn the replaced the stone wall and Mr. Duhaime said the split rail fence was not located exactly as shown on the plan but it was fine. A motion was made by Scott Duhaime, seconded by Ed Englemann to issue a certificate of Compliance for the project under 112-392. VOTE: Aye, unanimous. 6. Review Request for Proposals for Sunset Ridge, Wattaquadock Hill Road (112-525) The Commission discussed hiring an outside consultant for peer review of the ANRAD. It was agreed to contact several consulting firms as soon as possible. 7. Conservation Restrictions Carol Gumbart informed the Commission about a meeting she attended with Irene Del Bono of the Division of Conservation Services. Ms. Gumbart said that she specifically described the type of Conservation Restriction (CR) the Commission and Dr. Gaby were discussing and Ms. Del Bono indicated that it is possible that the state will find small CR’s in the public interest. Ms. Gumbart said that Ms. Del Bono did not have any problem with a CR being recorded before the Secretary of Environmental Affairs accepts it so long as it can stand alone if the Secretary doesn’t accept it. 8. Forbush Mill Road Conservation Parcels (Old Sawmill CA) Carol Gumbart said that several people have recently expressed an interest in seeing improvements made to these parcels The Commission agreed to conduct a site visit before the trees leaf-out (late April - early May). 9.

Scott Duhaime recommended that Ms. Gumbart contact Becky McEnroe or Dan Gaffney to determine the right location. Bolton Conservation Commission Minutes March 6, 2007 page 3 10.
