Delta Plan Interagency Implementation Committee

The Delta Reform Act (Act) of 2009 charged the Delta Stewardship Council to establish and oversee a committee of agencies responsible for implementing the Delta Plan. Each agency shall coordinate its actions pursuant to the Delta Plan with the council and the other relevant agencies. Water Code Section 85204


The Delta Stewardship Council established the Delta Plan Interagency Implementation Committee (DPIIC/Committee) after adoption of the Delta Plan in 2013 and continues to coordinate and oversee its activities as required by the Act.


The Committee strives to facilitate Delta Plan implementation through increased coordination and integration in support of shared national, statewide and local goals for the Delta. Maintaining focus on the intersection of Delta Plan and California Water Action Plan implementation with federal interests in the Delta, Council staff aims to craft a balanced agenda that highlights progress on achieving the coequal goals through four key elements: water supply reliability, Delta ecosystem health and restoration, Delta as a Place, and best available science in support of “One Delta, One Science.”
