The Susanville Indian Rancheria Corporation (SIRCO) was formed in 2009 by the Susanville Indian Rancheria (SIR), a federally-recognized Indian Tribal government located in Susanville, California. The Tribe elected to charter under authority of the Indian Reorganization Act (IRA) of 1934. The initial Rancheria Constitution and Bylaws were approved by the Secretary of the Interior on March 3, 1969.
In 2004, SIR developed a Master Plan that is used as a guide to address the utilization of the current land use, future land acquistion, economic development, the housing shortage, environmental concerns, infrastructure building and the overall health and well being of Tribal members. The concept of creating a for-profit holding company and for formulating the Economic Development Department as a formal branch of the Susanville Indian Rancheria Tribal governance infrastructure was identified during a Tribal Business Council Retreat and Strategic Planning Session in February of 2008.
With a grant from the Administration for Native Americans, Social & Economic Development Strategies for Native Americans (SEDS) Governance Program, a new tribal business was established that would operate independently from the Tribal Business Council with its own Board of Directors under accountability to its owner–the Susanville Indian Rancheria. SIRCO was initially chartered as a Tribally-chartered corporation, but was converted to a Federally-chartered, Section 17 Corporation in 2010.
