Hydraulic reports developed for WSDOT must be reviewed and receive concurrence by the State Hydraulics Office or RHE (per Table 1-1) prior to the project advertisement date. The State Hydraulics Office has delegated concurrence authority to RHEs. PEOs shall contact the RHE to verify the hydraulic report review process.
To help facilitate an efficient design and review process, a hydraulic report review process has been developed. The review will consist of several checkpoints or milestones of the design as it is being developed, followed by a complete review of the report. The purpose of the milestones is to establish communication among the PEO, the RHE, and/or the State Hydraulics Office, and other internal and external stakeholders during the hydraulic design. Each prescribed milestone is considered complete when the corresponding checklist is completed, along with deliverables, and submitted to the RHE reviewer(s).
