The primary focus of the meeting was the ongoing project on Winter Street, where a single-family home is planned. An existing driveway connects to Winter Street, and the site includes an intermittent stream and bordering vegetated wetlands (BVW). The applicant sought permission to temporarily cross the stream to conduct soil test pits, necessitated by changes in stormwater regulations since the project’s initial approval in 2017. Joe, representing the applicant, outlined the need for updated testing to comply with local stormwater bylaws due to changes in rainfall data and regulations.

Joe described the proposed method for crossing the stream, which involved using steel plates to bridge the channel, minimizing disturbance to the wetlands. He assured the commission that the temporary crossing would take no longer than one day under favorable conditions. A commission member inquired about the BMPs intended for the site and whether the test pits would adequately assess infiltration. Joe confirmed that a septic system design had been developed based on prior testing and that the new test pits would contribute to this assessment. Lucas Environmental’s review, conducted before the meeting, confirmed that the site conditions were favorable for the proposed work and that the stream was currently dry, facilitating the temporary crossing.

The commission discussed the implications of the proposed work, considering the site’s history and the need for updated assessments in compliance with evolving regulations.

In another discussion, the commission considered a proposed project that involved work near a temporary crossing and soil testing. A member suggested that the work be conducted under the existing order already issued by the commission, allowing for a negative determination. This approach aimed to avoid unnecessary administrative work by utilizing the existing order’s conditions, which addressed erosion and sedimentation controls for the project. The consensus leaned towards amending the existing permit rather than creating additional paperwork, with a suggestion for the applicants to withdraw their request without prejudice. This would enable them to proceed under the existing order with written confirmation and a request for before-and-after documentation of the work.

An audience member emphasized the importance of completing the work before adverse weather conditions, sharing concerns based on local historical flooding events. This highlighted the urgency for timely action.

The commission also addressed the continuation of the Notice of Intent for the DPW Wood Street right-of-way project. Representatives from VHB, the consulting firm, provided updates following the receipt of a final number from the Department of Environmental Protection (DEP) and addressed comments from a peer reviewer, Weston and Samson. Further discussion revealed a query from the DEP about the total area of degraded Riverfront Area (RFA) impacted by the project. The response confirmed that the area exceeded the 10% threshold, leading to a suggestion that mitigation measures be proposed. However, the representatives argued that traditional mitigation measures might not be feasible due to the nature of the project being a roadway construction. They presented alternatives, including limited repairs to existing disturbed areas, but contended that these options would likely lead to continued erosion and sedimentation issues.

The conversation included a visual aid showing the flow dynamics in the area, specifically noting a curb cut where water currently flows. An inquiry about the potential for rerouting the flow to mitigate erosion concluded that such rerouting would likely result in further impacts. The proposed project, including adding catch basins along the roadway, was theorized to help manage the flow and reduce erosion.

Another project discussed was the 0129 147 Hayden Road project, where representatives from environmental consulting firms and the engineering team presented updates. The revisions included a phasing exhibit and addressed stormwater comments. Concerns were raised regarding the clarity and specificity of the phasing plan, particularly regarding the full clearing and grubbing of the site. The commission emphasized the need for additional checks and balances within the construction documents to ensure compliance with the approved plans.

The importance of having a carefully laid out and monitored phasing plan was reiterated, given past experiences where inadequate oversight led to issues. The idea of having an owner’s representative on-site was introduced as a layer of management to ensure adherence to the plans. The conversation concluded with a consensus that additional review points should be itemized within the phasing plan to enhance oversight and protect the resource areas.
