Erosion Control Measures Structure No. 110-3 Dave Johnston to Stegall 230 Kilovolt Transmission Line
CX(s) Applied: B1.3
Date: 03/29/2012
Location(s): Wyoming
Offices(s): Western Area Power Administration-Rocky Mountain Region
Western Area Power Administration (Western) will repair erosion damage at Structure No. 110-3 of the Dave Johnston to Stegall 230 kilovolt (kV) transmission line located near southeast Torrington. Wyoming. Flood flows along the North Platte River in 2011 migrated the active channel bank towards Structure No. 110-3. The potential exists for future channel meandering to underline the foundation supports of the 80 foot steel lattice structure. To mitigate this potential, Western proposes to construct an in-ground modular block retaining wall along the perimeter of the structure to serve as a protective barrier.
