Conservation Commission Permits Geotube Expansion

Anna Day • April 4, 2025

Nantucket Community Can Vote NO at Upcoming Annual Town Meeting

After nearly 15 months, the Conservation Commission closed the public hearing on the joint SBPF - Town of Nantucket Notice of Intent (NOI) application to extend the existing installation of geotubes on the public beach four times its length to approximately 4,000 linear feet along the base of the Sconset Bluff.  The Commission formally voted (4-1) to issue an Order of Conditions (OOC) permitting the proposed project with conditions.

As data collected by project consultants indicates,
the geotubes are detrimental to the environment, increasing the erosion on surrounding beaches.  The NLWC takes the strong position that there are much more appropriate and less harmful alternatives,  especially given that the Town’s engineers have determined the relocation of Baxter Road can be completed by 2027.

The NLWC participated throughout the hearing process
  submitting seven written comment letters in addition to a multitude of public comments made with our professional consulting coastal engineer Trey Ruthven of Sustainable Coastal Solutions.

The NLWC does not agree with the Commission's final determination
that the project meets the necessary waiver criteria to receive a permit, and that the mitigation sand required by the permit will be sufficient to prevent long term negative impacts to our beaches and eastern shoreline. The Commission Chair cast the lone dissenting vote under the local wetlands bylaw.

One of the most critical issues
  addressed by the Commission in the OOC is the ever-growing deficit of mitigation sand that was required by the previous permit for the existing geotubes, which SBPF has steadfastly refused to provide. The mitigation conditioned in the previous permit was determined with SBPF’s own data, supported by MA DEP, and agreed to by SBPF.  It has been demonstrated by two independent coastal engineering experts that the failure to contribute the required mitigation has already resulted in significant damage to the Town-owned coastal beach  as well as privately owned properties to the north. This includes existing and increased future risk to the Lighthouseproperty. This violation of SBPF’s existing permit resulted in a removal order which was upheld by Superior Court, and is still outstanding.

The Commission did include a condition in the OOC requiring SBPF to provide the deficit, at least 105,465 cubic yards of sand, to the system.
However, they are allowing SBPF a period of 10 years to deliver the mitigation that was a requirement of their prior permit,  and the plan for how this is to be accomplished has yet to be determined. The applicants are required to provide such a plan for Commission approval.

The project’s path forward is not entirely clear. The Select Board must negotiate a new Memorandum of Understanding with SBPF and ultimately draft and vote on a new license agreement. Before they can do so, the Town of Nantucket must secure a positive vote on Article 81 from Town Meeting for permission to lease/license our Town owned beach to SBPF for the construction.
The NLWC strongly opposes Article 81 and the authorization of a lease/license of the public beach for this project.  We opposed the geotube expansion and we are opposed to the Article as drafted because not only would it allow the expansion but it is also too broad. Article 81 would undermine Annual Town Meeting’s ability to exert influence on alternative erosion control projects at this location in the future.
 

Nantucket Needs Your Presence & Support at Annual Town Meeting (ATM), which begins on Saturday, May 3rd to Vote this Article Down! 
Please Mark Your Calendars for ATM and Stay tuned for further updates and more information on our opposition to Article 81!

New partnership will transition conventional moorings in Monomoy to protect and restore Nantucket Harbor habitat The Nantucket Land & Water Council (NLWC) has received a generous grant from the Great Harbor Yacht Club Foundation to support the installation of eelgrass-friendly moorings in Nantucket Harbor, a major step forward in protecting one of the island’s most important marine habitats. Healthy eelgrass is essential to the vitality of Nantucket Harbor. Eelgrass meadows provide critical habitat for wild bay scallops and juvenile fish, improve water quality by filtering polluted runoff, absorb excess nutrients, store carbon, and stabilize shorelines against erosion and storm surge. Yet eelgrass in Nantucket Harbor has declined significantly in recent decades due to nutrient pollution, warming waters, and physical disturbance — including abrasion from traditional boat moorings. Since 2018, NLWC has worked with Harbormaster Sheila Lucey and her team, the Town of Nantucket and island partners on eelgrass restoration initiatives aimed at reversing this decline. One of the most practical and immediate solutions is transitioning conventional chain moorings to eelgrass-friendly systems — a key recommendation of the newly adopted Nantucket Eelgrass Management Plan. In 2022, NLWC partnered with Nantucket Harbormaster Sheila Lucey and Anderson Stillwater Moorings to design and implement an environmentally-sensitive mooring system adapted for Nantucket’s unique needs. The design uses a 300-pound pyramid anchor and an eco-rode that keeps gear suspended above the seabed, preventing the heavy chain “scouring” that destroys eelgrass beds around traditional moorings. The NLWC Waterkeeper vessel has been successfully secured using this mooring system for three consecutive seasons. Thanks to generous funding from the Great Harbor Yacht Club Foundation, NLWC and the Harbormaster’s Office will now launch a pilot program this spring, in partnership with local mooring companies, to transition up to 25 conventional moorings to eelgrass-friendly systems. Ed Orenstein, GHYC Foundation President, states: “The Foundation prioritizes projects that deliver both immediate and long-term benefits to Nantucket Harbor’s ecosystem and our community at large. These new eelgrass-friendly moorings accomplish both. We couldn’t be happier to team with NLWC on this impactful initiative and applaud Emily Molden’s leadership." NLWC will monitor the pilot sites to measure eelgrass recovery and seabed stability, with the goal of informing future harbor management decisions and expanding the program if successful. “Eelgrass is the foundation of our harbor ecosystem — without it, we lose scallops, water quality, and coastal resilience. The beauty of eelgrass-friendly moorings is that they solve a problem without restricting boating. This project shows conservation and harbor use can work together for the betterment of our environment and to the benefit of our community, and we hope it becomes a model for broader adoption.” – RJ Turcotte, Nantucket Waterkeeper The Nantucket Land & Water Council extends its sincere appreciation to the Great Harbor Yacht Club Foundation for their foresight, vision, and generous support for innovative solutions that protect the island’s land and water through science, advocacy, and community engagement.

As the end of the Fall season approaches, we would like to take some time to reflect on Nantucket’s recent Special Town Meeting, held on November 4th. The Nantucket Land & Water Council has been engaged in Nantucket’s discussion about short-term rental (STR) policy and regulation for many years. As an organization, we have, at times, faced questions from residents about the relevance of STRs to the NLWC’s mission . The NLWC’s mission is to help preserve the long-term health of Nantucket’s environment and community through the protection of our land and water resources. Development impacts the environment. This simple fact should come as no surprise. Our actions on the land have a direct impact on the health of our waters. Nutrients like nitrogen and phosphorus from septic systems and fertilizers, along with other contaminants such as those found in stormwater runoff, don’t just disappear. They travel through the soil and into our ponds, harbors, and drinking water. The accelerated development, repurposing of properties, and intensity of use associated with short-term rentals (STRs) as a business put increasing pressure on the island’s infrastructure, reduce habitat and biodiversity, and endanger our water quality. Of course, a community needs to change and develop and grow, but the health of our environment and the ability of a place to naturally support the people who live there are directly related to the intensity and type of development and growth that we, as a community, choose to allow and encourage. The NLWC has always made it clear that we are not opposed to all short-term rentals. We support the ability of island residents to short-term rent with reasonable restrictions. We have, first and foremost, sought to reduce the impact from investor-owned STRs, and reduce the intensity of use and development from properties that are maximized solely for the use of short-term rentals because of the cumulative environmental impacts that this type of use and development creates. We were very disappointed by the November STM vote, which resulted in the full codification of short-term rentals across all residential zoning districts of the island. It is clear that much of the community was incredibly alarmed by the simple messaging provided by Article 1 proponents that asserted this was a matter of maintaining an important property right or losing that right. Alternatively, we, as proponents of Article 2, attempted to communicate a more nuanced message that memorializing this right with reasonable restrictions would actually allow most residents to continue short-term renting in a meaningful way while helping to protect the future of our environment and community. As the dust settles, and our media expresses the reality of the inadequacy of our existing regulations ( https://nantucketcurrent.com/news/nantucket-banned-corporate-owned-short-term-rentals-a-loophole-is-allowing-them-to-continue ) , there is clearly more that needs to be done. All of our policies and practices relative to growth, development, and land and resource management , including STR regulations, must be scrutinized for their impact on our shared natural resources and adjusted where needed to protect the health of our environment and community. It is easy to make the claim that STRs as an issue is not “in our lane” and to suggest that how we use and develop our properties are somehow separate from: PFAS issues, contamination of our public water supply, nutrient pollution, and water conservation , but these are the exact concerns that compel the NLWC to engage in community conversations about growth, development, land use, and STRs. We are the voice for Nantucket’s environment, working to safeguard the present health and future sustainability of the island. This is our lane. We thank all of our members and friends for your support , regardless of your position or vote at STM. We know that, despite differences in opinion, we all share a deep care for this special place and a desire to protect what makes it unique. Together, we can shape policies that reflect both the needs of our community and the limits of our fragile island environment. Your willingness to stay engaged—ask questions, share concerns, and offer ideas—continues to strengthen our efforts. There is more work to do, and we look forward to doing that work with you.
