Water is the most powerful force on earth. Year after year, wet weather events cause property loss and result in significant remediation costs.
Calm-water banks and shorelines around lakes, ponds and stormwater basins erode at a gentler rate than coastlines and river banks because the water has a lower velocity. Common causes of calm-water bank and shoreline erosion include rainwater sheets flowing over unprotected areas, high-traffic spaces where people and animals are accessing the water and small-wave action caused from wind.
Proper bank stabilization is one of the easiest methods to protect calm-water shorelines. There are many shoreline stabilization methods, like the use of rock, synthetic materials, vegetation, or a combination of the above, with varying results and costs.
Rock effectively dissipates the velocity of moving water and is ideal for foot traffic. Stone, rock and rip rap come in various sizes. Choosing the correct type of rock and size is as important as the correct technique for placing the rock. Larger stone is more expensive, so protecting a long stretch of shoreline could go way over budget. Small stone can migrate and cause future problems if placed in areas of high flow.
