The proposed schedules had start of CDSRP and Anderson Dam Seismic Retrofit Projects in 2021 and 2022, respectively. These schedules were developed to address the water reliability issues discussed above, under the assumption that there was no other way to provide the necessary water supply reliability. Staff continues to evaluate raw water supply options during the construction of these projects and will provide a recommendation to the Board to properly prioritize the dam construction schedules as the permitting phases for both projects progress, and a more determinate timeline for the beginning of construction for each project is known.
