The most notable topic at the meeting was the notice of intent filed for the Cherry Hill Drive project, which proposed modifications to stormwater management systems to mitigate potential environmental impacts. Jill Man, representing Millipore, presented the project, emphasizing improvements like reduced pavement in buffer zones and a shift to a one-way traffic pattern to minimize environmental intrusion. Despite previous concerns raised by the commission regarding native tree preservation and invasive species management, Man assured the commission that these issues were addressed in the revised planting plan.

A critical element of the discussion was the peak runoff volumes. The engineering team had raised concerns about the potential impact on local water bodies, emphasizing the need for effective stormwater management following recent restoration efforts in the town. The commission scrutinized these plans, particularly regarding the proposed mitigation measures valued at approximately $250,000. To ensure compliance, a bond of $25,000 was suggested, representing 10% of the mitigation plan’s value. Mr. Baker, identified as a key figure in the project, affirmed that all work would adhere to approved plans. The commission ultimately voted to issue the order of conditions, contingent upon finalizing the stormwater permit and regular oversight to ensure adherence to protocols.

In another significant decision, the commission granted a waiver for work within the 50-foot no-build zone on Cherry Hill Drive, contingent upon compliance with established environmental standards. This decision followed assurances that the project would not adversely affect nearby native species or waterway health.

The meeting also addressed a request for a certificate of compliance for a culvert replacement on Summer Street. Bill Casey presented the completed project, highlighting the replacement of a deteriorating metal pipe with high-density polyethylene pipes and the stabilization of the downstream channel. The commission’s questions focused on the project’s performance, with Casey confirming its successful operation under favorable weather conditions. The commission unanimously approved the certificate of compliance.

Another agenda item involved the installation of a 575-foot gas main by Boston Gas Company along Maple Street. The project was presented by Tracy Set Halter, who assured the commission that the installation, which included 40 feet within a flood-prone area, adhered to best management practices to prevent erosion and runoff. The commission confirmed the necessity of the project and its coordination with town officials, approving a negative determination of applicability contingent upon adherence to outlined practices.

A proposal for a fixed pier extending from a property on Tibbitz Avenue over a salt marsh also received attention. The pier, designed to comply with local environmental requirements, faced scrutiny regarding its height-to-width ratio following recent changes in criteria from the Division of Marine Fisheries (DMF). The commission discussed the potential impact of the pier and float on local waterways, emphasizing the need for the structure to be raised during storms to prevent damage. After ensuring compliance with DMF recommendations, the commission approved the order of conditions for the project, including a waiver for work in a no-disturb zone.

Lastly, the commission deliberated on a real estate transaction involving the Dhys’ property, where unauthorized modifications had been made without proper notice of intent. Concerns included a sport court and other additions that deviated from the original order of conditions. The commission expressed the need for a site visit to assess potential impacts on bordering vegetated wetlands (BVW), considering possible mitigation plantings to compensate for any loss. The hearing was continued to allow time for further evaluation.
