San Francisco District Regulatory Division

As chief federal steward of wetlands - marshes, tidelands and vernal pools - the Corps' regulatory team has responsibility for regulating and enforcing rigorous environmental standards while balancing appropriate development. The Corps’ efforts to balance society’s many needs officially begin with the permit process. In cases where an impact on aquatic resources is unavoidable, organizations must obtain a permit from the Corps.  This process is designed to be fair and flexible and to provide timely decisions. In many cases, the Corps works with potential applicants during the planning and design of projects so that problems can be spotted early on and addressed, saving development costs while still reducing potential environmental harm.  The Corps is committed to ensuring that the public has the opportunity to provide input on projects that will have more than a minimal impact on the environment. In carrying out its regulatory program, the Corps works closely with a diverse array of federal, state, tribal and local government agencies, nonprofit groups, businesses and individuals.
