Body
SUMMARY:
The objective of the Calabazas Creek Rehabilitation Project (Project) is to restore the existing channel to as-built natural conditions, minimize future bank failures, minimize impacts to water quality and riparian habitat associated with bank erosion, remove non-native vegetation, add additional native vegetation and native trees, reduce the need for on-going maintenance, and continue to provide existing flood protection level of service to the community.
Project Background
During past inspections performed by Watersheds Operations and Maintenance staff, deficiencies with respect to current level of service were observed along the creek between Miller Avenue and Bollinger Road, including erosion, bank failures, and surfaces lacking adequate vegetation cover. These deficiencies were exacerbated as a result of 2016/2017 winter storm events.
The Project is being undertaken as part of the Watersheds Asset Rehabilitation Program (WARP). The Project scope of work entails repairing and stabilizing channel banks at 10 locations.
