DWR Provides Construction and Cost Estimate Updates for Oroville Spillways by Will Holbert Sep 6, 2018 Water News SACRAMENTO – The Department of Water Resources (DWR) on Sept. 5 provided an update on construction activities and estimated costs for the Oroville Spillways Emergency Recovery Project. Total project costs are now expected to exceed $1 billion. A DWR release detailed progress on the main spillway, emergency spillway and projects surrounding work on the dam. As work progresses in order to meet the Nov. 1 public safety construction milestone to fully reconstruct the main spillway, DWR’s current cost estimate for emergency response and reconstruction of the main and emergency spillways is $1.1 billion. Cost estimates are based on actual and projected work and may be adjusted further as work continues through completion of the project in 2019. DWR will continue to submit expenditures to the Federal Emergency Management Agency (FEMA) for reimbursement. To date, FEMA has approved reimbursement of $87.4 million of the $116.5 million submitted by DWR. DWR awarded an initial $275 million contract in April 2017 to Kiewit to immediately plan and mobilize crews and equipment to begin construction in May 2017. This budget allowed Kiewit to begin necessary work while the project design was completed, and was not an estimate of the total project cost. Final plans for the main spillway were completed in July 2017 while final design plans for the emergency spillway were completed and approved in August 2018.
