Bioengineered Living Shorelines: Innovation In Erosion Control
Lakes and stormwater ponds are often the biggest source of beauty in our communities, but without proper management, these systems can quickly become eyesores that produce harmful algae and bad odors, lead to damaged and eroded shorelines and result in displeased community members. Unfortunately, these issues often reach beyond the point of a quick fix by the time a professional lake manager gets called in to help implement a solution. This is regularly the case when we arrive onsite to look at an erosion issue on a lake or pond embankment. Rather than finding a few problematic patches of rock or soil, we discover steep, unstable banks, deep washouts, and extensive bottom muck caused by years without an erosion control plan in place.
Erosion is a natural process caused by wind, rainfall, poor design, cultural impacts like mowing and recreation, or simply an aging aquatic ecosystem. These erosion issues are all exacerbated by human disturbance. Unfortunately, erosion can also negatively affect your lake, stormwater pond, canal or coastline by causing loss of habitat and property value, nutrient loading, reduced storage volume and waterbody depth, and excess runoff. When topsoil is displaced, stormwater pipes and structures can be exposed and damaged. Over time, erosion can lead to the formation of trenches and gullies that pose a serious danger to the public.
There are many ways to control erosion with rip-rap, bulkheads, and other hard armoring systems; in certain situations, they may be the preferred option. In my experience, however, reestablishing the embankment utilizing vegetation, whether turf grass for recreation or native vegetation for habitat, has always been an excellent way to halt erosion and enhance community waterbodies. There are several best management practices that can help control erosion and establish vegetation, but a lot of them have a shorter life-span or planting restrictions. Fortunately, there is a exciting solution available for both the immediate and long-term stabilization of shorelines and hillsides.
- Bioengineered Shoreline Install
Bioengineered living shorelines are the latest technology in erosion control. These patented systems offer an innovative, environmentally-friendly solution to immediately stop shoreline and embankment erosion and create a natural foundation for vegetation. The most effective systems available are designed using a combination of eco-friendly, burlap sock-like fabric and heavy-duty knitted mesh. The “SOX” can be filled with local pond muck and sediment, which is why many property managers choose to pair this solution with proactive hydro-raking projects. After the woven mesh SOX systems are filled, they are then secured to the embankment and can be immediately sodded, planted with native beneficial buffer plants, or seeded through the mesh and fabric layers.
Lake and pond managers have relied on several different shoreline restoration techniques over the years, but this innovative system is certainly creating some excitement! It provides immediate stabilization while effectively filtering and buffering run-off water, removing harmful contaminants, and benefiting waterways and water quality, all the while providing a seamless planting platform and long-lasting erosion control. Restored banks and hillsides can be walked on within just a few days, making bioengineered shorelines a fast, aesthetically pleasing, and long-lasting solution for most properties.
Whether you decide to move forward with a complete shoreline restoration or are several years away, it’s imperative to properly budget and integrate proactive management strategies that protect your banks and hillsides, while preserving the water quality of your aquatic resource. Cultivating a beneficial vegetative buffer with flowering native vegetation will help stabilize soil during rainstorms. Deep-rooted flowering plants can also help pull excess nutrients from stormwater runoff, preventing the growth of nuisance weeds and algae in the water resource. Undesirable nutrients can be further combated with the professional application of naturally-occurring nutrient remediation products, which permanently “lock up” and prevent nutrients from fueling aquatic weeds or algae.
Just like lawncare, lake and stormwater pond management is an ongoing commitment that requires different approaches throughout the year. While no two waterbodies are the same, each and every aquatic ecosystem is susceptible to shoreline erosion and can benefit from custom management plans that integrate buffer management and nutrient remediation, as well as other sustainable tools like hydro-raking, aeration, biological augmentation, and regular water quality testing. Whether your waterbody is in its prime or has seen better days, contact your lake management professional to restore and prolong your water resources—starting with the shoreline.
