In a recent government meeting, discussions centered on the effectiveness of coastal protection measures, particularly the use of geotubes versus quar terraces for safeguarding bluffs and coastal banks. A representative emphasized that geotubes provide superior protection compared to quar terraces, asserting that the decision to proceed with the geotubes has already been made, and no further alternatives need to be considered. They highlighted the importance of having a removal and failure plan approved before construction begins, ensuring that any potential failures can be addressed promptly.
However, concerns were raised regarding the historical performance of geotubes, with one member advocating for an independent review of their effectiveness. This member pointed out that geotubes have consistently failed to provide adequate sacrificial sand, which is crucial for bluff protection during storms. They argued that the proposed design by Dr. Krievel, which includes a significant amount of sand, would better support the coastal system.
Further complicating the discussion, Trey Ruthven from Sustainable Coastal Solutions noted that the project plans are based on outdated survey data from June 2021. He warned that the coastline has eroded significantly since then, potentially affecting the project's viability. Ruthven also highlighted that the applicant has not complied with mitigation requirements since 2015, resulting in a substantial deficit of sediment that could exacerbate erosion rates.
The meeting underscored the complexities of coastal management and the need for updated data and thorough evaluations to ensure effective protection strategies are implemented. As the commission moves forward, the implications of these discussions will be critical in shaping the future of coastal resilience efforts in the area.
