One of the biggest threats to the long-term health and condition of Greensboro's streams is bank erosion. You may have noticed stream banks that suffer from severe erosion.

Eroded stream banks can negatively impact the stream segment and the aquatic habitat by carrying harmful pollutants such as fertilizers, pesticides, pathogens, and heavy metals.

What causes erosion?

As development increases in our community, there is less open space to absorb rainfall. Excess stormwater flows across pollutant filled parking lots and streets into storm drains that lead directly to local streams and creeks.

The amount of water and the speed of the flow has increased in recent years. Fast-moving water rips soil from the stream and exposes tree roots causing unstable trees to fall. 

Sediment is one of the most common pollutants found in local North Carolina waterways. The majority of the sediment is derived from bank erosion. Large amounts of sediment can change the path of the stream.

The Stormwater Management Division works to stabilize and restore eroded stream banks in the community.
