Peer Review

To facilitate the development of a transparent, reproducible, and effective methodology to prioritize the State’s funding for levee work, the Department of Water Resources prepared an interagency agreement with the Council to develop a methodology that uses existing data to quantify assets and other benefits associated with each Delta island and tract to establish a basis to judge the effectiveness of State funds to accomplish State objectives. Following a competitive proposal solicitation, a consulting team led by ARCADIS was awarded the contract for the project.


The methodology will support development of the approach that will be used to prioritize and classify islands to guide a long-term State levee investment strategy that will be based on the best available science and modeling. An Independent Scientific Review Panel was selected by the Delta Science Program to review the methodology developed by ARCADIS and its scientific basis. This review ensures that the approach taken is transparent, robust, and sufficiently sensitive to quantify and prioritize the assets and risks to State interests associated with each leveed island and tract.


Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
