Caltrans District 2 Hwy and Bridge Construction Project
Focus:
Environmental Compliance
Restoration Services
Challenges
This project aimed to repair and upgrade four highway bridges in Lassen and Plumas Counties. Bridge maintenance work included painting and repairing bridge joints to meet State and Federal bridge standards.
The project areas contain sensitive riparian and wetland habitats at four locations: North Fork Feather River, Susan River, Dill Slough, and South Greenville Overflow Channel. The project locations are within or near habitat for the following regulated species:
Migratory Birds and Birds of Prey
Roosting Native Bats
Swainson’s Hawk (Buteo swainsonii)
Bats were observed within the project area at the North Fork Feather River site, and evidence of roosting bats was observed at bridges over Dill Slough and Susan River, prompting careful monitoring of all bridge maintenance work activities.
Innovative Solutions
We developed and implemented a Water Pollution Control Plan (WPCP), a Bat Exclusion Plan, and an Avian Exclusion Plan for the Project. Prior to the start of work activities, we conducted focused surveys for sensitive species. The assessment of bridge specific wildlife activity guided our implementation and adaptation of the plans and enabled us to proactively address environmental concerns throughout the evolution of the project. Once construction began, we closely monitored work activities to ensure the protection of sensitive wildlife.
