2018-19 Permanent Storm Damage Repairs - Cottonwood Creek
In 2017, the City of Livermore experienced storm damage in multiple locations. All projects within this project have been completed, except for the Cottonwood Creek Water Line and Bank Erosion Restoration Project. The storm caused erosion to the banks and creek bed of Cottonwood Creek exposing a major transmission domestic waterline and reducing the cover over a reclaimed waterline to less than one foot. Additionally, the storm damaged riparian mitigation planting areas that were established under the El Charro Mitigation Plan. Temporary repairs were made to protect the domestic waterline, the reclaimed waterline, and the banks. However, further work is necessary to permanently reinforce the utilities, stabilize the banks and creek, and restore riparian mitigation planting areas. This project will incorporate floodplain benches, pools, riffles, and hardening elements.
