Wilbraham discusses beaver deceiver for Twelve Mile Brook as costs and permit needs rise
Summary
Commissioners discussed rising water at a pedestrian bridge on Twelve Mile Brook caused by beaver dams and identified $10,150 in potential funding (Community Preservation funds plus an MSCPA grant); Beaver Solutions estimated installation at $5,475 but commissioners warned permitting and studies could add significant costs.
Commissioners discussed recent beaver activity that has dammed Twelve Mile Brook beneath an existing pedestrian bridge, causing water to rise toward the bridge. The minutes note that previously approved Community Preservation funds plus a grant from MSCPA total $10,150 and that Beaver Solutions estimated the device installation would cost $5,475. Members cautioned the deceiver may not work under high stream or storm flows and that permitting, professional services and any required studies could substantially increase total project cost.
Chairman Christopher Brown said he would walk to the bridge and assess the situation before further action. The minutes do not record a formal vote to spend funds or to file a MESA application; commissioners discussed options and next steps, flagging the potential for additional permitting costs and uncertainty about the device’s effectiveness in high flows.
