2021 Renovation Update #6 - Lake Banks

We are nearing the completion of the construction aspect of our renovation project, and although several tropical systems have threatened Southwest Florida, we have managed to avoid any significant damage or major delays! Construction and grassing on holes 1, 2, 9, 10 & 18 still needs to be completed. We are hopeful we will be finished and grassing completed on these holes in the next ten days. 

An aspect of the renovation that has gone exceptionally well is the reclamation and stabilization of the lake banks. Although healthy turfgrass provides terrific stabilization of soil, over the last 29 years several shoreline areas did have varying degrees of erosion. 

Two locations where fairly significant erosion occurred were the lake banks adjacent to the greens on holes 1 and 5. These greens are in the closest proximity to water and both have significant sheet flow across their surface to a concentrated area. 

In these areas we used the DredgeSOX Erosion Control system to reclaim and stabilize the shoreline. The DredgeSOX product is a geotextile based system with a patented anchoring design that is used to stabilize shorelines, hillsides and other areas to reclaim deteriorated or lost area and prevent future erosion. The DredgeSox product consists of a double layer of knitted high-density polyethylene (HDPE) mesh. When installed, the mesh is filled with soil and can be shaped to match, or change the slope or shape of the area. In the two areas we utilized the product we were successful in adjusting the shoreline to regain significant area that had been lost. The results are dramatic!

In other areas where sheet flow was not as concentrated and damaging, but improvement and smoothing could be achieved, we utilized a skid-steer to level and reagin the desired slope of the lake bank prior to establishing the new turfgrass.
