Proposition 1 Water Storage Investment Program: Funding the Public Benefits of Water Storage Projects
Proposition 1 of 2014 dedicated $2.7 billion for investments in water storage projects. The California Water Commission is administering the Water Storage Investment Program (WSIP) to fund the public benefits associated with these projects.
In July 2018, the Commission approved maximum conditional funding amounts for eight projects that collectively would boost California’s water storage capacity by 4.3 million acre-feet. The projects range from expanding existing reservoirs to boosting groundwater storage to building 21st century surface storage facilities.
Through a rigorous selection process, the Commission chose the eight projects based on the public benefits their projects will provide, such as flood control, ecosystem improvement, water quality improvement, emergency response and recreation. Applicants must now complete the remaining Proposition 1 requirements, including final permits, environmental documents, contracts for the administration of public benefits, and commitments for non-Proposition 1 funding.
Throughout this process, the Commission will continue to meet with the applicants, state agencies and stakeholders to review the status of each project. Once an applicant has obtained all the necessary permits, documents and contracts, the Commission will hold a final award hearing.
The table below shows the $2.7 billion in Proposition 1 funds broken down by Maximum Conditional Eligibility Determinations (MCED) from July 2018, and administrative costs.
