Alliance Pipeline contracted Rachel to provide creek restoration and protection services in the fall of 2015 near Janesville, MN. One of Alliance's natural gas pipelines that crossed the Handy Creek was experiencing erosion nearby and was losing some of the original soil protection that it once had. Rachel was contracted to re-grade the creek bank and provide aggregate and earthen protection. Rip rap material was placed at the toe of the slope and roughly half way up the 10 foot high bank. The remaining upper bank was protected by placing soil in layers and wrapping it with two fabric layers. The earthen retaining wall type approach is a great way to naturally protect the creek bank as it allows grass and plantings to grow through the fabric layers. Inter-Fluve and Alliance's careful planning and design ensured that the project was completed successfully and within budget.
- 320 tons of specialty rip rap aggregates
- 575 sf of fabric-encapsulated soil lifts (earthen retaining walls)
- 46 plantings
