Wilson & Company provided preliminary design, final design support, and prepared the hydraulic analysis and floodplain development permit application package for this channel restoration project. Historical development in the project area had constrained the floodplain in this reach and the low flow channel had incised significantly into highly erodible soils. The floodplain was widened to the extent practical and the low flow channel was relocated and reconstructed to increase its meander and stability.
The project includes:
- Boulder and cobble lined low flow channel
- Soil loaded and seeded turf reinforcement mat lining the floodplain bench
- Outer slopes reinforced with buried soil riprap in critical areas
