Our Mission: The U.S. Army Corps of Engineers (USACE) delivers vital solutions, in collaboration with our partners, to strengthen our Nation’s security, energize the economy, and reduce risks from disasters.

 Our History: Serving the Nation since 1866, the San Francisco District is an integral part of the South Pacific Division.

  • Coastal fortifications: From 1860-1900, our Engineers built strategic fortifications in the San Francisco Bay Area.
  • Mapping: By 1879, our topographical engineers prepared maps documenting the western United States.
  • Dredging and Harbor Improvements: By 1889, the district completed harbor improvements in San Francisco, Napa, Petaluma, Redwood City, San Pablo Bay, and many more, significantly boosting the regional economy.
  • Vignette (Oakland Harbor): In 1874, our Engineers began dredging in Oakland Harbor, and in 1898, completed a 19-ft deepening project.  Later deepening work provided material to construct Treasure Island (home of the 1938 World’s Fair).  In 2009, our Engineers completed a 50-ft deepening project that contributed 3 million cubic yards of material for restoring 998 acres of tidal wetlands at the former Hamilton Army Airfield. 
  • Debris Removal: In 1943, the Chief of Engineers directed the San Francisco District to begin a hazard collection program in the San Francisco Bay following a seaplane accident involving Admiral Chester Nimitz.  Today, the district removes an average of 1200 tons of debris from the San Francisco Bay each year.

Our People: We are a diverse and competent workforce of over 260 public service employees.

  • Our workforce includes civilians, active duty, reserve component, and retired military.
  • Over 50 employees possess Ph.Ds or other advanced degrees and numerous employees with professional certifications (among them 27 Professional Engineers and 5 Project Management Professional).

Our Area: Our area of responsibility is an extremely complex operating environment with national significance.

  • Our area is over 40,000 square miles in northern California and southern Oregon, encompassing 23 coastal river watersheds.  Our area includes over 900 miles of coastline and 22 Federal ship channels, internationally-significant agriculture, and is home to over 6.5 million people.
  • Our center of gravity is the San Francisco Bay.  It is the largest estuary on the West Coast and the location of two strategic ports, Silicon Valley, and numerous Fortune 500 companies.
  • We maintain two dams and reservoirs that reduce flood risk and provide water supply to over 600,000 people while providing recreation to over 1.5 million visitors annually.
  • Our U.S. Congressional delegation: California has 26 Members (2 in Senate, 24 in House of Representatives) and Oregon has 3 Members (2 in Senate, 1 in House of Representatives).

Our Program: The majority of our program is focused on the civil works missions of navigation, flood risk management, environmental restoration, emergency management, and regulatory oversight.  

  • Our Fiscal Year 2017 Program is currently approximately $72 million, pending additional work plan funds, with an inventory of over 65 active projects.
  • Our Fiscal Year 2018 Program is estimated to increase to over $100 million with a continued inventory of over 65 active projects.
  • The District performs Interagency and International Support (IIS) work for other federal agencies, such as the Veterans Administration, U.S. Coast Guard and the U.S. Environmental Protection Agency, with the majority being associated with the VA Medical Center facility improvements and upgrades.

Balancing Economic Development and Environmental Stewardship:

  • The San Francisco District’s navigation mission supports the San Francisco Bay Area’s $68 billion annual maritime industry and $660 billion gross domestic product (GDP) that ranks 19th in the world.
  • The District is working on the largest wetlands restoration projects in California and is leading the effort to beneficially reuse dredged material.
  • The District is working collaboratively to restore endangered Coho Salmon in the Russian River Watershed in an effort recognized by the National Oceanic and Atmospheric Administration as a “Habitat Blueprint for Success.”
  • The District’s Regulatory Program executes about 1,000 permit actions per year, enabling billions of dollars of environmentally compliant economic development.
  • The district’s Bay Model Visitor Center, powered by solar energy and the only “Net Zero Energy” facility in the USACE region, hosts over 250,000 visitors annually and serves as a center for strategic outreach.
