The hydraulic report is intended to serve as a complete documented record containing the engineering justification for all drainage and stormwater installations and modifications that occur as a result of the project. The primary use of a hydraulic report is to facilitate design review and to assist in PS&E preparation. The hydraulic report should be well written, show conditions before and after construction, and be defensible in a court of law. This section contains specific guidance for developing, submitting, and archiving a hydraulic report.
A Fish Passage and Stream Restoration Design (FPSRD) certificate number is required for all authors and co-authors of any portion of a fish passage and stream restoration design specialty report. See Table 1-1 for a list of specialty reports and other requirements. An FPSRD certificate number is given to those who have viewed all of the training modules and successfully passed the comprehensive exam. Additional information, training resources, and the point of contact for this training can be found on the WSDOT Hydraulics Training web page. As WSDOT updates the FPSRD training modules a re-certification number is also required. Any updates to this training will be posted on the WSDOT Hydraulics Training web page.
A Highway Runoff Manual certificate number is required for the stormwater designer who designs a new stormwater BMP on WSDOT right-of-way (ROW) or modifies an existing stormwater BMP on WSDOT ROW, or where a stormwater BMP is designed or modified and will be turned back to WSDOT ownership. The Highway Runoff Manual certificate number is given to those who have successfully passed the Highway Runoff Manual training course. See training information on the WSDOT Hydraulics Training web page.
A scour analysis is required for all WSDOT projects or WSDOT-managed infrastructure associated with scour or that have a potential to be impacted by scour, such as water crossings, walls, roadway embankments, and other WSDOT infrastructure. A WSDOT Scour Certification Record (SCR) number is required for all stream team members that are conducting scour calculations, lateral migration, scour analysis, and reviews as part of or supporting specialty reports. See Table 1-1 for a list of specialty reports and other requirements. An SCR certificate number is given to those who have viewed all the WSDOT Scour Training Workshops and FHWA Bridge Scour Workshop Recordings; completed National Highway Institute (NHI) Course 135046, Stream Stability and Scour at Highway Bridges, and NHI Course 135048, Countermeasures Design for Bridge Scour and Stream Instability; and successfully passed the comprehensive exam. Additional information, training resources, and the point of contact for this training can be found on the WSDOT Hydraulics Training web page. As WSDOT updates the Scour Training modules a re-certification number is also required. Any updates to this training will be posted on the WSDOT Hydraulics Training web page.
The following training courses are required to obtain a scour certification:
• FHWA Bridge Scour Workshop Recordings
• NHI Course 135046, Stream Stability and Scour at Highway Bridges
• NHI Course 135048, Countermeasures Design for Bridge Scour and Stream Instability
• WSDOT 2023 Scour training
