Student researchers from the Cohasset Center for Student Coastal Research (CSCR) presented a sobering look at the health of Scituate and Cohasset Harbors on Monday, documenting a significant loss of local eelgrass populations. Students Henry, Bridget, and Amelia explained that eelgrass is critical for carbon sequestration and shoreline stabilization, but their data shows a steep decline in density since 2021. Bridget noted that eelgrass is one of the best remedies for climate change, serving as a vital buffer for wave action. However, the team reported that restoration efforts face steep odds. CSCR representative Susan Bryant told the Commission that while restoration is vital, it currently sees only a 10% success rate these days, though the team is experimenting with new methods such as using mesh bags and attaching seeds to shellfish to improve outcomes. Amelia added that the team is investigating whether invasive tunicates are acting as parasites on the grass.

The Commission also signaled a likely shift toward a formal amendment process for "The Cottages" development after the new owners requested larger decks and staircases for 24 units. Conservation Agent Jen Smith noted that the expanded footprints would be as close as 25 feet to the wetlands in some areas, with crushed stone replacing grass underneath. Eric expressed concern about the loss of natural drainage, stating that any potential infiltration and uptake that any plant could provide in these areas on the rear of the home would be something. Removing that with crushed gravel—I understand it's pervious, but there is no infiltration potential. Chair Frank Snow agreed that the cumulative impact was significant, noting, my gut feeling is that it probably warrants an amendment.

The discussion regarding the 40B project also drew sharp questions from resident Liz O'Reilly regarding equity and safety. O'Reilly questioned if the smaller decks were being relegated to affordable units, arguing that if everybody else is getting a big beautiful deck... I don't think that would be fair. She also voiced concerns about the long-term impact of buried propane tanks near the marsh, suggesting that 20-30 years from now they're going to discover that doing the propane was not the smartest idea especially with the wetlands. Snow clarified that the Commission’s jurisdiction is limited to the environmental impact of the tanks rather than the fairness of deck sizes.

A persistent impasse over unpermitted work at 42 Crescent Avenue continued as the board grew weary of shifting calculations regarding a permeable paver patio. Following previous sessions where the board expressed frustration over unpermitted expansions, Snow demanded a definitive comparison of what was originally allowed versus what was actually built. I want a chart, Snow said. What was conditioned and what did you actually construct? I'm not looking to keep beating a dead horse, but I don't have the numbers. Applicant representative Darren noted that the team had already begun removing portions of the patio, but the board maintained that mitigation plantings would be required for the violation before any final approval is granted.

In other business, the Commission unanimously approved a septic repair and pool removal at 49 Whittier Drive. Joe Webby of Webby Engineering explained the site was a failed system for a home currently for sale. Robbie questioned the stability of the site, noting I want to make sure that material is adequately compacted so the leaching field does not experience any kind of settlement. The board also debated whether to require the applicant to clean up debris and a chain-link fence on the adjacent Ellis Estate town land. While Snow argued that if that debris was placed there by the applicant, it's not unreasonable to ask them to get it out, Roger urged caution regarding work on town property. I think it's going to set some stuff where other folks are going to start to potentially want to clean up areas that may not be theirs to touch, Roger said. Motion Made by P. Scott-Pipe to approve the project as presented. Motion Passed 5-0.

The meeting concluded with the annual reorganization of the board. Snow was reappointed as Chair, with Penny Scott-Pipe noting that Frank, your knowledge of the wetlands—you are a gold mine of information. Brendan, who took on the role of Vice Chair, suggested the importance of shared leadership, noting it is good to have a mix of folks that would be comfortable with different roles. Additional appointments included Scott-Pipe as the Community Preservation Committee liaison, Roger as the Coastal Advisory liaison, and Robbie as the Beach Commission liaison. Motion Made by P. Scott-Pipe to nominate Frank Snow as Chair. Motion Passed 5-0. Motion Made by P. Scott-Pipe to nominate Brendan as Vice Chair. Motion Passed 5-0.
