The proposed gas utility project by National Grid took center stage during the meeting, as it involves complex coordination with another bridge replacement project in the same vicinity. The consultant representing National Grid laid out the plan for the project, which entails the abandonment of the current underground gas regulator station. New gas mains are to be laid within the riverfront area and buffer zone, which necessitates careful consideration of the environmental impact. The commissioners probed the timeline and methods for decommissioning the existing station, as well as the proposed excavation and backfilling processes. Erosion control measures and catch basin inserts were also discussed to mitigate the potential environmental repercussions during construction.

The debate also veered into the ownership of the land where the new gas regulator station is to be located, with confusion over whether it is town-owned or falls under state jurisdiction. Road paving emerged as an ancillary issue, with considerations on whether to repave the road after the bridge construction project is completed. This topic underscores the intricate interplay between town infrastructure and environmental conservation efforts.

Another subject was the management of invasive species, particularly the removal of knotweed around Grove Pond. The commission deliberated on the use of volunteers to tackle the invasive plant and explored the potential of creating honey from knotweed as an innovative byproduct of the environmental management project. The Nashua River Watershed Association’s request for determination regarding native seeding planting along Grove Pond was also a point of discussion. The project aims to restore riparian buffers and increase native vegetation, with an emphasis on minimizing disruption to park activities and maintaining vistas from the park.

The environmental theme continued with conversations about the protection of newly planted saplings from potential damage and vandalism in the park. The commission considered using signs or temporary fencing to safeguard the saplings and discussed coordinating with the Parks Department to ensure their preservation. Technical difficulties with presentation equipment briefly hampered discussions but were eventually resolved, allowing the meeting to proceed.

Stormwater management emerged as another focal point, with the commission tackling issues such as an overflow problem due to an accidentally decommissioned drain on East Main Street. The commission is seeking solutions with the relevant authorities and is also planning to collaborate with the planning board to review and update stormwater regulations.

The meeting touched on the treatment of different ponds for invasive plants, with discussions on the cost difference between treatments and the need to include certain species like fragmites in the treatment for Pine Meadow Pond. Updates were also provided on the Conservation Office’s attendance at the MCC conference and dialogues with the DPW and town planner on stormwater items.

The success of a recent stormwater presentation was noted, as were the challenges of interpreting FEMA flood maps.

In addition to these projects, the commission mentioned plans for site visits to assess trees and potential construction projects, the coordination of trailblazing, and the installation of new markers for the Pine Meadow project. There was also a brief mention of the presence of Easter eggs on the trails and the importance of informing the community about conservation efforts and seasonal wildlife activities.

The commission deliberated on the need for flood storage in certain areas.
