Tom Perry from Northern Construction Services presented plans for the temporary bridge, which is part of a larger project to replace the West Main Street bridge. He explained the need for a crossing to manage construction access and detailed the inclusion of erosion control measures such as drainage stone and geotextile fabric. Perry assured the committee that once the project concluded, the area would be restored to its original state. Concerns were raised over the access road’s width and maintenance, especially regarding potential water level fluctuations due to beaver activity or backflow from the Nashua River.

The discussion probed into the technical specifications of the bridge. Participants questioned whether the proposed eight and a half-foot width was adequate for construction vehicles, with suggestions for alternative routes if necessary. The bridge’s design called for timber construction, potentially reinforced with steel plates, to accommodate construction loads. Concerns about the stability of gabion baskets used for supporting the crossing were addressed, with preferences expressed for minimal excavation to preserve the natural integrity of the site.

As dialogue continued, the committee focused on the bridge’s environmental implications. Participants debated the use of extensive excavation and its impact on the flood zone area. Administrative approval for site clearing was suggested as a prudent step to understand the ground conditions before finalizing plans. The need for a reassessment of the area post-clearing was emphasized.

In procedural matters, the committee discussed the withdrawal of an application without prejudice, allowing for future adjustments. This motion passed unanimously. They revisited a public hearing that had been continued due to pending comments and site visit questions. Adjustments to plans included incorporating a retaining wall to reduce encroachment. The committee stressed the importance of continuing public hearings on projects like Creative Materials on Willow Street.

Further updates from the conservation office revealed issues with a previously issued certificate of compliance, unrecorded until this meeting. The new certificate aims to prevent confusion in future lot sales. Concerns from residents about communication on the Lincoln Hills site plan were addressed, noting that although the conservation commission lacked jurisdiction, their comments influenced the landscaping plans to include native plants.

They planned to distribute a variety of plant seeds to residents, aligning with budget considerations. Additionally, a new state program on climate resiliency was introduced, offering a centralized online resource for local officials to enhance climate-resilient practices.

Lastly, upcoming educational opportunities were highlighted, including the MACC fall conference on October 25th, with discussions on budget allowances and the availability of online courses. The committee concluded with a light-hearted exchange about street lighting aesthetics before unanimously adjourning the meeting.
