Lake Bank Restoration using Geo-Tubes
Flow Way Community Development District (CDD) has undertaken a restoration program of the lake banks in the Community. Over the years, natural wave action caused by wind and fluctuating water levels has caused lake bank erosion in various portions of the 27 lakes and flow way canal. Lake Inspections were completed in 2022, so a 5-year Capital Improvement Program (CIP) could be prepared to address the non-compliant permitted slopes in a timely manner. The Stormwater Erosion Report prepared by the District Engineer in March, 2022 provides a recommendation for lake bank restoration using geo-tubes. Over the next few months Lakes 2, 7, 9 and 17 will be under construction for the installation of these geo-tubes to restore the lake banks to their original permitted condition.
Schedule of construction is estimated from late-January to mid-March 2024.
Geo-tubes are sediment-filled sleeves that are used to help protect lake shores from erosion. To install a geo-tube, the lake needs to go under a pump dredging procedure. Pump dredging is performed in shallower areas to gather up all the bottom sediments and dispose them to another location or reuse the sediment to recreate a shoreline. There are three types of geo-tube bags that are used to create a new shoreline, which are a base tube, middle tube, and a sacrificial tube. The base tube will help create the new base of the shoreline, the middle tube will help create the vertical height along with setting the long steep slope at a proper ratio, and the sacrificial tube will provide a base for sod to complete the new shoreline.
The reason why shore restoration is important is because recycling soils eliminates the cost of offsite sediment disposal. Addressing the natural process of erosion and saltation will help restore the pond’s depth, slope, and grades that meet permit requirements. The process includes the use of the pond’s old materials to restore the eroded shoreline.
The final product will protect residents from potential fall accidents along the lake’s bank and promote volunteer littoral to grow and create better aesthetics for the entire community.
