Service Areas Engineering, Natural Resources Project Description Big Horn Riverbank Bioengineering Design and ImplementationIn 2017, the Big Horn River flooded just north of Worland exposing a 24-inch sewer outfall line to the City Wastewater Treatment Plant. The 465 linear feet of sewer line was repaired and rip-rapped under an Army Corps of Engineers 404 Permit. Y2 was contracted to design and implement revegetation or “bioengineered armor” for the existing riprap along the river. Y2 designed a plan that incorporates bioengineered armor that meets the Best Practices for …

Service Areas Engineering, Survey Project Description Y2 completed a geotechnical investigation report for a 1.4-mile road that was being designed on steep slope conditions in Teton County. The field investigation was completed for eight parcels along the proposed road in order to develop future structures. Y2 prepped the field work, used a split spoon drill to complete and select samples for testing, and dug dozens of boreholes. The team completed a full index of lab work including gradation testing, plastic and liquid limit testing, slope stability analysis, …
