05:34The primary focus of the meeting was on a new notice of intent concerning a project proposed by William Hearn for the replacement and elevation of a seawall on River Street. The plan, presented by Kieran Healey from the BSC Group, involves replacing the existing wooden seawall with a structure elevated by approximately two feet to prevent overtopping by rising tides. The project also calls for the removal of several trees within the riverfront area and the coastal bank, raising environmental concerns among commission members. The discussion centered on the methods proposed for stabilizing the seawall, including the installation of wooden dead men, which are traditional anchors used for support, and the potential ecological impact of extensive excavation required for their placement.

15:03Several commission members raised questions about the project’s details, particularly the balance between tree removal and replanting. Concerns were voiced about whether the plan to replace trees with shrubs represented an equitable exchange, given the ecological importance of trees. The conversation also touched on the possibility of using helical anchors, an alternative to dead men, which could reduce excavation and potentially lessen the environmental footprint. This option prompted a discussion about the necessity of an alternatives analysis to explore lower-impact solutions.

09:26The commission also scrutinized the transitional details between the existing seawall and the proposed bulkhead, pointing out potential issues with exposure and infiltration. The need for more comprehensive documentation was emphasized to ensure all environmental implications are adequately addressed. The exchange highlighted the complexities involved in balancing development needs with conservation priorities.

01:31:06Another topic discussed was the enforcement matter involving Susan and Robert Lyn of 57 Pheasant Circle. They were called to address unpermitted vegetation cutting within a velocity flood zone and bordering vegetative wetland. Britney, a commission member, observed the cutting and initiated a draft enforcement order. The homeowners attributed the cutting to a miscommunication with landscapers and expressed willingness to cooperate in rectifying the situation. The commission planned a site visit to assess the damage and explore potential restoration options, emphasizing the importance of collaboration and the need for a restoration plan.

42:43The meeting also covered discussions on several other projects, including a proposal to elevate a foundation and construct a retaining wall on Powers Lane. This project, involving land subject to coastal storm flowage and a coastal dune buffer zone, prompted inquiries about the soil designation and the use of pervious pavers for accessibility improvements. Additionally, a project on Driftwood Lane addressed erosion concerns with plans for trench drains and wildflower planting. The commission expressed urgency in implementing these measures to mitigate further erosion.

01:41:31As the meeting drew to a close, the commission approved the minutes from the previous session and announced upcoming community events, including the Yarmouth annual community cleanup day and a public meeting on the town’s hazard mitigation plan.
