Trans Bay Cable LLC and the City of Pittsburg, CA selected URS to assist in route selection, permitting, remediation and construction phase services for a high voltage submarine transmission line in San Francisco Bay.
The 53-mile-long submarine cable has been successfully permitted and buried in the bottom of San Francisco Bay between project electrical converter stations (AC/DC) adjacent to Pacific Gas & Electric substations in Pittsburg and San Francisco to help meet San Francisco’s long-term energy supply needs in a cost-effective, energy-efficient manner.
Professional services provided by URS include submarine cable siting study/constraints analysis, preparation of environmental studies, multiple Phase I and Phase II hazardous material investigations for proposed and alternate converter station sites in San Francisco and Pittsburg, marine survey (sediment quality and characteristics over the 53-mile-long submarine cable route in the Bay), remediation services, and regulatory permitting for pertinent federal, state and local/regional agencies.
URS, including subsidiary Cleveland Wrecking Company, also performed hazardous material remediation and demolition of buildings in San Francisco and Pittsburg, environmental compliance, and engineering, and construction management.
URS worked with the client, regulatory permitting agencies, and environmental organizations to successfully obtain necessary permits and approvals on a fast-track basis in an innovative and efficient manner for a large and complex project. URS successfully permitted the project and construction has been complete. Commercial operation of the cable began in November 2010.
