Size: Total protection of 385 feet of stream bank

Features

• Development of 5 alternative designs and preliminary cost estimates for stream bank stabilization
• Utilized bioengineering techniques in alternative designs
• Selected alternative used native plantings on an armorflex slope
• protection with a riprap toe tied into gabion baskets on the upstream
• and downstream ends of the project and bendway weirs with root wads
• to redirect high velocities from the stream bank into the channel centerline
• Focus on long term slope protection and stability

SEH Services
