Intuition & Logic provided analysis and final design services for the Galaxy/ Meteor/ Brierhall project, an incising reach of stream extending approximately 2,800 feet behind a residential development.  The incision is progressing through easily erodible loess soil resulting in high, unstable banks and exposed and threatened sanitary sewers and infrastructure. 

 

The final design included a series of rock grade control structures. The severely incised reach upstream of the concrete channel was completely restored by raising the channel bed with excavated soil and reshaping, fabric and planting eroded banks.  High stress areas were further stabilized with composite revetments.
