The board meeting was dominated by a discussion about the impact of a substantial beaver dam, estimated to be between 60 to 80 feet long, near the Anquidy Dam. The dam has caused elevated water levels, threatening to inundate nearby roads. With concerns about public safety and potential road erosion, the board debated possible solutions, including the contentious option of trapping and euthanizing the beavers. This would require a permit from the Board of Health, given the legal complexities surrounding beaver management.

Roy Chambers raised concerns about previous efforts to control the beaver population and the ongoing risk of flooding. The conversation veered towards alternative solutions that might allow for coexistence with the beavers while minimizing the risk to infrastructure. Suggestions included changing road materials to better handle water flow and prevent erosion. The board acknowledged the historical absence of beavers in Massachusetts and their recent resurgence, which complicates efforts to balance ecological preservation with public safety.

Further complicating the situation is the potential impact of future developments under the MBTA Communities Act, which could increase housing density in nearby areas. Concerns were voiced about the capacity of the existing infrastructure to support these developments, particularly in light of predicted flooding scenarios for 2030, 2050, and 2070. The board noted that rising tides could impact areas like Riverside Drive, Thistle, and Courtland Circle, emphasizing the need for proactive planning.

In addition to the beaver dam issues, the meeting addressed an important sewer pump project on Granite Avenue. The town is set to receive grant funding for a $3 million upgrade to a major sewer pump station. This project involves replacing an underground pump, with some components visible above ground, and constructing a retaining wall to protect nearby wetlands. The board discussed the potential traffic disruptions during construction and the need for careful environmental consideration.

The board also reviewed a proposal by the Boston Gas Company to expand its perimeter security fence at the Milton Take Station. This expansion involves removing approximately 16 trees to ensure a 10-foot clearance beyond the expanded area. The plan includes habitat enhancements for rare species, which are under review by Natural Heritage. Some board members expressed concern over the tree removal, emphasizing the town’s standards for tree replacement based on circumference.

In another matter, the Conservation Commission discussed the modification of planting requirements at five Wagon Wheel Drive. Due to unexpected challenges with planting saplings along a lawn edge, the team proposed utilizing a wetland area for planting. This would involve a diverse mix of native shrubs suited to wetland conditions. The board approved the modification, pending submission of corrected planting numbers.

The meeting also covered a legislative proposal to accelerate wetlands restoration, brought forth by Arthur and supported by the Ottabon Society. The board agreed on the importance of reducing bureaucratic delays in wetland protection and restoration, and a motion was passed to support Senate Bill 557.
