The April 29, 2024, Meeting

The Currituck Board of Commissioners is scheduled to convene on Monday, April 29, 2024, from 1:00 p.m. to 5:00 p.m. One of the primary agenda items for discussion is the county’s 2023 Shore Stability Study. This comprehensive 58-page report provides detailed analysis and insights into coastal dynamics and erosion trends affecting Currituck County.

A Unique Phenomenon

Unlike its neighbors, Currituck County has experienced a unique phenomenon of gaining sand rather than experiencing erosion. The study offers an in-depth examination of various factors influencing shoreline stability, including sediment transport, beach profiles, and erosion patterns. However, the executive summary provides a concise overview that encapsulates the key findings and recommendations.

Continued Monitoring

Importantly, the study emphasizes that Currituck County’s approach to beach nourishment should prioritize continued monitoring rather than immediate action, given the overall net volumetric gain observed along the Assessment Area. The executive summary serves as a valuable resource for stakeholders and decision-makers, clearly understanding the issues at hand and informing strategic planning and policy development moving forward.

As the Board of Commissioners convenes to discuss the study’s findings, the executive summary will provide a succinct reference point for addressing coastal management challenges and ensuring informed decision-making for the community’s benefit.

The Study Recommendations

The 2023 Currituck Beach Monitoring and Beach Stability Assessment identified several key recommendations for the area’s beach management and erosion concerns. These include continuing to monitor beach profiles, developing a comprehensive beach management plan, and coordinating with neighboring Dare County on regional sand resource investigation.

One notable finding of the assessment was the unique phenomenon of sand gain observed along Currituck beaches, contrasting with the erosion experienced by neighboring areas such as Virginia Beach and Dare County. This unexpected net volumetric gain challenges the conventional understanding of coastal dynamics in the region, where erosional trends have been documented in surrounding areas.

Danger Lurks Under the Sea

Given this context, the question arises as to whether Currituck should allow its neighbors to harvest its sand resources. This debate raises important considerations regarding the potential impacts on coastal stability, sediment transport dynamics, and ecosystem health. Collaborative efforts with neighboring jurisdictions are essential to assess the feasibility and implications of such actions, ensuring a balanced approach to coastal management that prioritizes long-term sustainability and resilience.

The Alteration of the Nearshore Shelf

Harvesting sand for beach nourishment, while intended to mitigate erosion and maintain or restore beach width, can have several effects on coastal environments. One significant impact is the alteration of the nearshore shelf, which can disrupt natural sediment transport processes. By removing sand from offshore areas, the balance of sediment movement is disrupted, potentially leading to changes in coastal currents, erosion patterns, and the distribution of sand along the shoreline.

Marine Habitats and Ecosystems

Furthermore, the process of dredging sand can disturb marine habitats and ecosystems, impacting marine life such as fish, shellfish, and bottom-dwelling organisms. It can also stir up sediment, potentially causing water quality issues and affecting aquatic plants and animals.

A Temporary Solution

Additionally, while beach nourishment projects aim to replenish sand and protect shorelines, they are often temporary solutions. They may not address the underlying causes of coastal erosion, such as sea level rise and climate change. In some cases, beach nourishment can even accelerate erosion in adjacent areas by altering natural sediment dynamics.

Long-Term Environmental Impacts

Overall, while beach nourishment can provide short-term benefits by protecting coastal properties and infrastructure, it is essential to consider its potential long-term environmental impacts and explore sustainable approaches to coastal management and erosion mitigation.
