Chico Water Pollution Control Plant Outfall Replacement

Chico, California

Foothill Associates prepared the Riparian Habitat Mitigation and Monitoring Plan for the City of Chico Water Pollution Control Plant Outfall Replacement Project to addresses requirement of the project’s Streambed Alteration Agreement with the California Department of Fish and Game code, Biological Opinion produced by National Marine Fisheries Service (NMFS), U.S. Army Corps of Engineers (Corps) Nationwide Permits, and Mitigation and Monitoring Plan required by the California Environmental Quality Act (CEQA). The Plan addresses mitigation measures deemed necessary for riparian habitat disturbance associated with levee excavation for placement of a pipeline and a new outfall diffuser into the Sacramento River. The mitigation plan also outlined a monitoring plan for long-term monitoring and maintenance over five years. Foothill Associates prepared a planting plan for the riparian planting area using a re-planting ratio of 3:1 to mitigate for project impacts to riparian habitat.

 

Foothill Associates conducted construction monitoring and prepared daily and monthly compliance reports during construction of the project and a final post construction compliance report in compliance with the California Endangered Species Act Incidental Take Permit issued by the California Department of Fish and Wildlife for covered species including Central Valley spring-run Chinook salmon, Sacramento River winter-run Chinook salmon, and giant garter snake. Foothill Associates also conducted Worker Environmental Awareness Program training for giant garter snake and served as the project’s Designated Biologist. Biologists monitored the site for five years following restoration.
