The Onion Branch Bank Stabilization Project extends from U.S. Highway 79 to near the confluence with Brushy Creek and has experienced some severe erosion problems due to increased flows in recent years.  The existing conditions of the banks have eroded to the point of placing the City's existing water, wastewater and stormwater infrastructure in jeopardy.  This project will consist of protecting the banks with the construction of mechanically-stablilized earth (MSE) walls, protecting the water and wastewater lines with grade-control structures constructed from large diameter rock, extending existing stormwater lines, and revegetating the banks with more drought tolerant vegetation.
