The Department of Water Resource (DWR) Central Valley Floodplain Evaluation and Delineation Program is a comprehensive effort designed to protect against loss of life, flood damages, and emergency costs for both existing and future developments caused by future flood events. It is intended to support both regulatory and structural solutions as it protects the State’s populace and infrastructure.
The bond expenditure process has been established by DWR, and approved by the Department of General Services to use four five-year regional contracts for engineering support. The contractor selected for each regional contract will be required to perform specific detailed floodplain delineation tasks issued by task order at the direction of DWR. The task order products must meet minimum engineering standards necessary for U.S. Army Corps of Engineers (USACE) studies, FEMA’s National Flood Insurance Program requirements, and DWR application needs.
The detailed floodplain delineation studies for the Central Valley river systems will be the primary task for these contracts. The four regional contracts are structured and managed using the following geographical area assignments:
- Upper Sacramento River System
- Lower Sacramento River System
- Upper San Joaquin River System
- Lower San Joaquin River System
In support of these four regional contracts, the bond expenditure process will include two Letters of Agreement between DWR and USACE. USACE will assist DWR in developing the hydrology studies necessary for the Central Valley, and also serve as a Quality Assurance/Quality Control agency to establish consistent standards for the stream hydraulics for the four regional floodplain delineation contracts.
