Project Specifications
- Product: 4ft TrapBags—positioned in trenches along the dune line. 2 rows installed back-to-back.
- Material: UV-resistant geotextile, reinforced with geogrid for added structural stability.
- Filling: Locally sourced sand.
Initial Solution
In the wake of Hurricane Sandy, TrapBag barriers were deployed along the dune line to stabilize the area’s shoreline. The barriers were positioned in trenches and filled with sand. The system was designed for rapid deployment, so TrapBag was able to provide relief to an already struggling area. The barriers have successfully prevented further erosion and safeguarded the community’s infrastructure, proving an effective long-term solution for coastal defense.
Unintended Longevity
Although initially planned as a temporary line of defense, the TrapBag system has provided over 10 years of protection. Despite rising sea levels and continual wave damage, the barriers remained effective.
2024 System Reinforcement
To ensure continued protection against rising sea levels and more intense storm activity, additional TrapBags were installed in May 2024. This expansion strengthened the existing system by reinforcing vulnerable areas and addressing new erosion patterns. By strategically integrating new barriers with the old barriers, the now reinforced system is equipped to provide continual protection to the residents of Fire Island.
Key Outcomes
- Immediate Impact: TrapBag barriers stabilized the shoreline, protecting, homes and critical infrastructure.
- Cost Efficiency: The system’s longevity provided residents with long-term, necessary protection.
- Scalability: The original barriers were easily adjusted and reinforced with new barriers to provide continued protection without the burden of replacing all of the original TrapBags.
- Recognition: The project’s success has been featured on ABCNY.
Conclusion
TrapBag has proven to be a reliable, long-term solution for shoreline defense at Fire Island. The system has a unique ability to adapt to changing environmental needs and deliver continued protection against coastal threats reinforcing its value as a cost-effective and sustainable method for erosion control. The successful integration of additional barriers in 2024 highlights TrapBag’s scalability and commitment to providing sustainable protection to coastal communities.
