Mattacashan Valley residents propose house relocation to address erosion concerns

During the Nantucket Historic District Commission meeting on June 3, 2025, significant discussions centered around a proposed residential project aimed at addressing coastal erosion concerns. The project involves relocating a structure closer to the road to mitigate the impact of ongoing shoreline erosion, with plans for two modest additions to the existing home.

The proposal includes applying for a variance from the Zoning Board of Appeals (ZBA) to allow the structure to be positioned within the 35-foot setback line, a move that has been permitted in similar cases due to the unique circumstances of the area. The applicant emphasized the importance of maintaining the architectural integrity of the home, proposing simple massing and window configurations that align with the existing structure's design.

Commission members raised questions about the proximity of the house to the road, with some expressing concerns about safety and the potential for traffic issues. The applicant clarified that the road in question is not heavily trafficked and is somewhat misrepresented in official maps, which may not accurately reflect its current use due to erosion changes over time.

The discussion highlighted the delicate balance between preserving the historic character of the district and adapting to environmental challenges. The applicant noted that the family intends to make improvements to the home to enjoy it for years to come, despite the structure's limited lifespan due to erosion risks.

As the meeting concluded, the commission acknowledged the complexities of the proposal and the need for further review, particularly regarding the variance request. The outcome of this discussion will play a crucial role in shaping the future of residential development in areas vulnerable to coastal erosion, reflecting broader community concerns about safety, preservation, and environmental adaptation.
