Client: Humboldt Bay Harbor Recreation and Conservation District and City of Eureka
Funding Source: Humboldt Bay Harbor Recreation and Conservation District and City of Eureka
Project Location: Humboldt Bay – Eureka, CA
The Humboldt Bay Harbor Recreation and Conservation District and City of Eureka have chosen Pacific Affiliates to complete project permitting, design and management for their maintenance dredging operations for more than 25 years. The cooperative project has been performed every 5-7 years and results in the removal more than 200,000 cubic yards of sediment from the waters beneath publicly owned local marinas and docks.
Pursuant to State of California protocol, the project was reviewed for consistency with state environmental law through the CEQA process and permitted through the United States Army Corps of Engineers, California Regional Water Quality Control Board, City of Eureka, Humboldt Bay Harbor Recreation and Conservation District, California State Lands Commission, Caltrans, County of Humboldt and California Department of Fish and Game. Commenting agencies included NOAA Fisheries and US Fish and Wildlife Service. Additionally, our staff of engineers worked closely with Humboldt Baykeeper in their efforts to preserve and maintain the natural beauty of Humboldt Bay and surrounding areas as part of the project.
As part of the project, Pacific Affiliates completed all conditional, pre and post dredge hydrographic surveys of all ten dredging locations. Collected data was used to design dredge templates, verify quantities and process contractor payments.
The project was successfully completed permitted and completed in 2006. Pacific Affiliates continues to operate as the project engineer with annual monitoring and permit compliance review.Tasks Performed:
