Shorts from the Conservation Commission, April 9

Proposed Fox Hill irrigation. John Bakewell and Kevin Brown, who farm the upper portion of the Fox Hill Conservation Land, met with the Conservation Commission (ConsCom) on April 9 to discuss a potential irrigation well. They currently have a 275-gallon tank on site that they fill by hauling in water. They said the driven point well would likely be less than 20 feet deep, the approximate limit for an above-ground pump. A deeper well with a submersible pump is also a possibility.

Power for the pump would come from solar panels. Warren Lyman of the Land Stewardship Committee indicated they had not yet taken a position on a well. While Lyman had concerns about setting precedent and encouraging others to propose infrastructure on conservation land, he personally favored this project. He also said that he felt the farming agreement requires that the land be restored to its previous condition if farming ceases.

The exact location of the proposed well is still to be determined. The commission decided it needs more information about well design, location, depth, and pump noise levels. A site visit and further discussions are planned.

99 Davis Road. Jonathan Bollen, of the engineering firm Stamski and MNary represented homeowners Larissa Shyjan and Robert Skrivanek at a continued public hearing relative to their request to construct a pool, patios, and a retaining wall, and to do associated grading near bordering vegetated wetland. Based on an impact assessment, the Natural Heritage and Endangered Species Program has approved the project, which is located in Priority Habitat for a state-listed rare species. A Department of Environmental Protection file number has now been received. There being no other outstanding matters, the commission approved the project.

278 South Street. Homeowners Elizabeth Ahern and Andrew Barlow wish to demolish their 1836 house, which is in a wetland buffer zone, and build a new house and attached garage at essentially the same location. They also plan to upgrade the septic system to conform with current Board of Health regulations. The existing barn will remain. Mark Sleger of Alan Engineering presented the project. Conservation Administrator Sylvia Willard complimented him for a highly accurate wetland delineation and report. The commission approved the project. It was noted that the ConsCom’s permitting authority relates solely to protection of wetlands and water bodies and does not extend to the question of removing an historic building.

38 Prospect Street. The commission had issued an enforcement order in September of 2008 stopping unpermitted tree cutting within the 100-foot buffer zone of a bordering vegetated wetland, and requiring homeowners Barbara and Thomas Bjornson to file a permit request with the commission. At the public hearing Thomas Bjornson presented a plan to remove approximately 60 trees. He indicated that they wanted to cut those near the house for safety reasons and others to create lawn areas. According to a case history prepared by Willard, the plan was prepared and signed by Carlisle resident Jeff Brem of Meisner Brem Engineering. Brem had indicated to Willard that Mike Toohill of the environmental consulting firm ENSR had flagged the wetland boundary. The report says the plan “lacks topography, flag numbers and is unstamped.” Toohill and Brem were not present at the meeting and the Bjornsons were representing themselves. The commission asked for more information, scheduled a site visit, and continued the hearing to May 14 at 8:30 p.m. ∆
