Key Points - Structures

To produce the most practical and flexible design, each hydraulic aspect and the resulting design frequencies must be considered and established based upon the relative risks and costs. The hydraulic frequency establishes a design storm and associated discharge and the criteria establish the acceptable level of performance during that storm. Instead of the simple term “design frequency”, use the terms “backwater design frequency”, “roadway overtopping design frequency”, “freeboard design frequency”, etc. The plans are to show the frequency to which each aspect of the project is designed.
