CPRA evaluates sand sources for Raccoon Island restoration in Terrebonne Parish
Raccoon Island's ecological future is at a critical juncture, as discussions at the Louisiana Legislature's recent meeting highlighted urgent restoration needs. The island, located in Terrebonne Parish, serves as a vital habitat for brown pelicans and various fish species, but it faces significant erosion challenges exacerbated by recent hurricanes.

The meeting revealed alarming data on the island's degradation over the years, particularly following Hurricane Ike in 2008, which breached the island and led to the detachment of its sand spit. Recent assessments show that the island continues to erode, with sediment supply dwindling, threatening its ecological integrity. "Sand is a key component for the restoration techniques that we evaluate," officials emphasized, underscoring the importance of sediment management in the restoration process.

Two potential sand sources for restoration were identified: Ship Shoal and Raccoon Point Shoal. While Ship Shoal is a significant resource, Raccoon Point Shoal is preferred due to its minimal impact on wave climate and alignment with the Louisiana sediment management plan. This plan aims to ensure sediment availability not just for Raccoon Island but for other nearby islands as well.

Financially, the restoration efforts are projected to cost between $30 million and $35 million, with a notable difference in logistics depending on the chosen sand source. The meeting concluded with a commitment to refine these estimates as the project progresses, emphasizing the urgency of action to preserve Raccoon Island's unique ecosystem.
