Soil Erosion Control

Our Soil Erosion and Sedimentation Control (SESC) Program strives to protect the waterways of Washtenaw county and beyond. This program assures the appropriate design and execution of SESC measures during earthmoving activities within the county. 

Dust could generated on construction site from vehicle.

Sediment is the greatest pollutant by volume impacting our lakes, streams, and wetlands. Sediment is the product of uncontrolled erosion. Construction is one of the major causes of erosion in Michigan. 

Erosion and sedimentation can: 

  • Cause the loss of fertile topsoil
  • Fill in lakes and streams
  • Increase flooding
  • Cause harm to plant and animal life 
  • Cause structural damage to buildings and roads
