Project: Stream Repair at Henderson County Residence




Ambrose Landscapes

... AFTER!

This streambank on the Youngblood property in Henderson County was badly eroded in recent years by hurricane-related stormwater. The pattern we found was typical: Collapsing sections of streambank alternated between the stream's two sides, because water tends to flow across the earth in a serpentine way. In fall 2007, after inspecting the stream, we submitted a plan for repairing it -- based on principles of natural channel design -- to NC Arboretum stream-restoration expert Jason Zink, who quickly approved it.
We began and finished our restoration of this stream in a single day. 


<==Our workers grade each bank back to a gentler angle, which will allow the force of gravity to slow and redirect rushing stormwater, just as a banked speedway track slows a race car.
==>Machinery cannot be used in streams without undergoing an extensive permitting process, but saves time and money elsewhere. 


<==Grasses are planted under the natural-fiber cover, which is staked to hold together. Native shrubs, sharpened like stakes on the root end, are planted through the cover at carefully arranged distances to stabilize the bank, where they begin to grow immediately.
==>As the fiber biodegrades, the shrubs will take root and begin their natural work of holding the streambank's
soil in place.
