What Causes Erosion?

Erosion occurs when forces like waves, water levels, rain, wind, groundwater, frost and human activities displace sand and soil from one area to another. These forces act continuously, reshaping the shoreline over time.

Identifying High-Risk Erosion Areas

High-risk areas erode at a rate of at least one foot per year over a minimum period of 15 years. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) conducts studies to identify these areas, guided by state laws.

Determining HREAs

EGLE employs a meticulous process to determine HREAs. By comparing historic and current aerial photos, they measure the distance between the old and current shorelines. We see from these measurements that erosion rates (in feet per year) are problematic.

Mitigating the Risks of Michigan’s Soil Erosion

Building structures too close to eroding bluffs poses significant risks, including the potential collapse of the structure into the lake. Planned development and construction within HREAs require careful consideration and adherence to setback regulations. Locating structures safely away from the bluff not only mitigates risks but also promotes natural shorelines, benefiting both residents and wildlife.

Soil Stabilization is Key to Preventing Soil Erosion

Understanding erosion, its causes, and the identification of high-risk erosion areas are fundamental steps in responsible coastal management. By following regulations, obtaining permits, and implementing mitigation measures, we can protect our shorelines while fostering sustainable development in Michigan’s coastal regions.

Coastal Renew is working hard to keep Michigan’s seawalls and shorelines intact, and we know that together, we can safeguard our coastal environments for future generations.
