What impact does disturbing sand dunes have on V Zone development?

Disturbing sand dunes can significantly impact development in V Zones, which are coastal areas subject to high-velocity wave action during flood events. Sand dunes serve as natural barriers that protect inland areas from floodwaters, essentially acting as a defense system against storm surges and erosion. When these dunes are disturbed—whether through construction activities or other forms of development—their ability to absorb and dissipate wave energy is compromised. This can lead to increased vulnerability to flooding and potential damage to structures built in these areas.

If the sand dunes are not properly evaluated before development, the consequences can be severe, as it may result in an increased risk of damage from flooding. Structures that are built without assessing the impact on the natural landscape, including dunes, could face greater flood hazards, leading to higher repair costs and increased risk to life and property. Therefore, the correct choice highlights the importance of evaluating the impacts of development on natural features like sand dunes to ensure adequate flood protection is maintained.
