Furneaux Creek & Tributary 6E1
Erosion Control Improvement Study





Existing Erosion Problems

The first phase of the Furneaux Creek and Tributary 6E1 Erosion Improvement study involved the preparation of Preliminary Plans for approximately 15,000 lineal feet of channel. Portions of the overall project area were included in the 1993 Carrollton Bond Program for erosion control improvements. The purpose of the study is to stabilize the channel sideslopes, control future channel downcutting, and protect existing sanitary sewers and other improvements located within the floodplain area. The preparation of Preliminary Plans included hydraulic analyses to define erosive forces within the channel and approximations of future stable channel slopes. The Preliminary Plan utilizes a combination of channel grade control structures, reduction of channel sideslopes, protective armoring and native vegetation to provide an overall stabilization plan. The plan is divided into a series of six reaches and includes a total of 25 grade control structures, relocation of selected sanitary sewers, channel armoring, and approximately 20 acres of proposed planting areas.
